Parthasarathy, D. Prasath, in Handbook of Herbs and Spices (Second Edition), Volume 1, 2012. Winter Wheat This article was written by Peter Johnson , Agronomist, Real Agriculture. With this technology, the rice breeder is now able to transfer and incorporate desirable genes into rice genome, no matter where the gene comes from. The challenge of food security still continues and demands the adoption of new approaches to ensure safe and sufficient food for everyone. Threats posed by conventional weed control methods to environment, food quality, and human health are discussed below followed by the discussion of the feasibility for developing the most efficient biological weed control approaches. Many insect-resistant plant varieties have been developed through cloning genes encoding proteinase inhibitors (Kim et al., 2009) and amylase inhibitors (Mehrabadi et al., 2010). The recom­mended dose of chemical fertilizer for the new seeds of wheat and rice in terms of NPK in 90-45-45 kg per hectare. High-yielding varieties are found naturally less resistant to pests in comparison with their progenitors. Disclaimer 9. To meet water requirements, there must be a controlled source of water at the disposal of farmers. “High yielding” is kind of a misnomer. Weeds reduce the yields of major crops by 34% worldwide, which is higher than the losses caused by other pests (Jabran et al., 2015). The progressive and enterprising farmers have largely im­proved their standard of living by their industry, while the lethargic and orthodox cultivators could not adopt the new technology suc­cessfully and many of them are still in the grip of poverty and under­nourishment. Apart from benefits gained from these practices, they have also given rise to unexpected outcomes bearing threats to sustainability of such practices as well as survival of human beings and other life forms on Earth. Among them, transgenic plants with the insecticidal gene from Bacillus thuringiensis (Bt) might be the best example on agronomical improvement. The yield capacity of each variety is given as a percentage of the control varieties (which themselves are proven varieties of a number of years standing), which is rated as 100. So, a variety which has a yielding capacity of 104 is deemed to be 4% better yielding than the control varieties. The side effects of pesticides include killing of susceptible nontarget species and disturbance of biodiversity. Before rust resistant varieties were developed, many areas treated wheat growing so high risk, they avoided growing the crop altogether. Bt eggplant (Solanum melongena) was developed and field tested by the collaborative research between the US-based company Monsanto and Maharashtra Hybrid Seeds Company (Mahyco), India, by incorporating a crystal gene (Cry1Ac) from B. thuringiensis (Krattiger, 2010; Cotter, 2011). Transgenic tomato plants targeting more than one homolog than a single unit of ACC oxidase by using RNAi technology during the ripening stage would be more effective than a single homolog (Gupta et al., 2013). Even in the years of droughts (1987-88 and 1988-89), the farmers could harvest very good crops of paddy with the help of canal and tube well irrigation. Unfortunately, the credit agencies in India, generally, serve the larger farmers who are economically well off and politically well connected. The Bt gene encodes the delta-endotoxin highly toxic to lepidopteran insects. The perennial varieties mature in 190-220 days while the annual ones in 190-230 days. Together, these hold exciting potential to accelerate plant breeding progress. The introduction of plant monocultures and indiscriminate and widespread application of chemical pesticides resulted in an insurgence of pests, development of resistance, and occurrence of residual toxicity. Therefore, pest management is an important component of crop production since its inception (Oerke, 2006). Maximizing the number of plants in a given space is a high-yield method. These insects and pests seriously attack the plants, hamper their growth and reduce the yield substantially. The highest yields are achieved in areas of well-managed irrigation and with adequate amounts of chemical fertilizers. , 1986). Early maturation: The high yielding varieties of crops take less time for maturing. Conventionally, weeds are controlled using manual, mechanical, and chemical methods (Chauvel et al., 2012). As a matter of fact, electric power has a vital role in the development and extension of HYV. It grows At the same time, decreased levels of ethylene in RNAi-ACS fruits lead to altered levels of various ripening-specific transcripts (i.e., upregulation of PA biosynthesis, ascorbic acid metabolism genes, and downregulation of cell wall hydrolyzing enzyme genes).

They pose the biggest challenge to food production worldwide since the start of agriculture. This competition deprives crop plants of space, nutrients, moisture, light, and other growth requirements. Common factors for crop improvement - definition Crop variety improvement can be achieved by the process of selection. Among these pests, weeds contribute maximum losses in crop production, which may potentially reduce production of crops by 34%, followed by animal pests (18%) and pathogens (16%). At the outbreak of a disease in the crop the entire area should be sprayed. It may be emphasized that excessive irrigation and inadequate irrigation are both injurious to HYV of wheat and rice. Results in this publication are aggregated over a number of years and on an MiR156 targets an important gene in fruit ripening, colorless never ripe (CNR), as reported by Molesini et al. A brief discussion on the inputs and infrastructure requirements for HYV is imperative to ascertain the myth and reality of the success of the Green Revolution in India. Among many useful aids which increase the efficiency of the farmers are seed-cum-fertilizer-drill, well de­signed plant protection equipment’s, Dunlop-carts, trolley, threshers, sprayers and tractors. High Yielding Varieties Seeds are undoubtedly land substituting, water economizing, more la­bour using, and employment generating innovation; nevertheless, they are very delicate and sensitive and therefore require a great deal of care if a successful harvest is to be obtained. At first the new varieties were highly susceptible to disease, and pesticides were necessary to obtain the high yield potential, but later varieties have been bred with a greater resistance to pests. In 2009, Bt eggplant was approved for commercialization in India, but the Indian government continues to impose a moratorium on its release because of public resentment (Jain, 2010). The … Apart from controlling pest populations, they have posed new challenges. The Bt cry protein is nontoxic to humans and animals, but toxic to insects (BANR, 2000). The poor and small farmers are thus deprived of the re­quired inputs, so essential for the successful cultivation of HYV of wheat and rice. The response of traditional varieties to chemical fertilizers is more in terms of vigorous vegetative growth which leads to pre-harvest lodging of the crop. There is little disagreement that the Green Revolution acted to reduce agricultural biodiversity, as it relied on just a few high-yield varieties of each crop. Already, 16 PAU recommended high yield varieties are being sown in Punjab, which includes PAU developed varsities (both long and short duration) like PMH-1, PMH -2, PMH 11, Parkash-1. Pesticides are chemical substances applied to control pest populations. The chimeric RNAi-ACS (1-aminocyclopropane-1-carboxylate synthase) construct designed to target ACS homologs effectively repressed ethylene production in tomato fruits and enhanced tomato shelf-life by 45 days. Ethylene suppression brings compositional changes to the fruits by enhancing polyamine (PA) levels. Prohibited Content 3. Nigeria releases 19 high yield crop varieties, one chicken breed to farmers By AgroBusiness Times on September 4, 2018 The Federal Ministry of Science and Technology produced 19 new varieties of crops with a high yield to increase agricultural production. HYV give rise to short stemmed, stiff strawed plants that re­spond well to heavy dozes of fertilizers. For example, the per hectare consumption of chemical fertilizers in India is only about 75 kg per hectare as against 525 kg per hectare in the Netherlands and about 500 kg per hectare in Japan. Data are col-lected from as many sites as are available and statistically analyzed. Based on WordNet 3.0, Farlex clipart collection. Most of the Indian farmers being poor have very little purchasing power and are unable to supply the prescribed doses of fertilizers. This means that when fertilizers are supplied to high yielding varieties their yield increases substantially. They were also short with a stiff straw, and so, unlike the tall traditional varieties, did not lodge with higher yields. Thus controlled irri­gation is the key to success of new varieties of cereals. The transgenic approach provides a novel way for rice breeders to use genes other than those from rice and its relatives. Many farmers, especially those in environments where high-yield crop and livestock varieties do not prosper, rely on a wide range of crop and livestock types. Similarly, in 1970-72, large uncovered piles of wheat accumulated at the rail­way stations of Punjab and Haryana were damaged due to the un­timely heavy rain falls in the month of May. Elsanta) by an intron-hairpin-RNA construct containing the partial sense and corresponding antisense sequences of CHS was separated by an intron obtained from an F. ananassa quinone oxidoreductase gene. Privacy Policy 8. The associated inputs like chemical fertilizers, insecticides and pesticides also perform satisfactorily only if timely irrigation is pro­vided to the crop. For example, a farmer, having a tractor and blade terrace, manages to grade his field to a much better level in the course of time as compared to a farmer not having the similar sources of power and equipment’s at his disposal. Although, it involves centuries old practices, a major breakthrough in pest control was the development of pesticides. Several transformation protocols have been deployed successfully for the introduction of foreign genes into rice. Certain weeds have also been reported to produce allelochemicals which suppress root and shoot growth of crop plants. Simply put, crop yield is the For the recuperation of fertility, the soils are rested in the form of fallowing or they are en­riched by applying manures (compost and green) and chemical fertil­izers (NPK). The agrarian institutions like banks and cooperative credit societies have great responsibili­ties. The high-yielding varieties developed by classical plant breeders have been essential to maintaining adequate food supplies for the ever-expanding world population (Bennetzen, 1996). It is a potent insecticide and very much toxic to lepidopterans (Cohen et al., 2000), dipterans (Andrews et al., 1987), and coleopterans (Herrnstadt et al., 1986). In the areas exclusively dependent on rains (Brahmaputra Val­ley) and in the dry farming areas (Rajasthan, Marathwada, etc.) Plagiarism Prevention 4. HYV are, however, not very successful in the areas of heavy rainfall. Advances in genetics and genomics have fostered a revolution in genome-level understanding of crops (Cooper et al., 2004; Nelson et al., 2004; Moose and Mumm, 2008). Newer approaches are needed to meet the great increase in food production necessitated by population growth in developing countries. The timings of irrigation and the quantity of water supplied are decisive for the performance of the crop. Sharda Choudhary, ... Radheshyam Sharma, in Genetic Engineering of Horticultural Crops, 2018. High-yielding varieties are frequently also high-maintenance varieties. Apart from canals, the government tube wells, pumping sets and tube wells installed by the farmers are necessary to fulfill the water demand of the new seeds. The greatest achievement in the field of agriculture is the development of Bacillus thuringiensis (Bt) insect-resistant crops using plant transgenic technology. A combination of very high transgene expression and improved protein stability resulted in mortality of even Bt-resistant insects (Kota et al., 1999). However, due to pest management practices, the yield reductions of wheat, maize, rice, soybean, and potatoes account for 26%, 31%, 37%, 29%, and 40%, respectively. Irrigation is the most important input required for the successful cul­tivation of HYV. The study shows that CNR is also negatively regulated by APETALA2a (a target of miR172). Direct methods employ all the techniques primarily aimed at weed control (Shad, 2015), including manual, mechanical, chemical, and biological. Image Guidelines 5. The new seeds require water at specific periods of growth, development and flowering. No species can be eliminated from nature and continuous disturbance of its habitat through agricultural practices increased the emergence and diversity of pests. Enormous machinery, like tractors, threshers, sprayers, tillers, chaff cutters, pumping sets, etc., are required for the timely operations of sowing, weeding, spraying and harvesting of HYV. The list of 310 new crop varieties includes two bacterial leaf blight disease resistant rice (Pusa 1592 and Punjab Basmati-3), one blast disease resistant variety of rice (Pusa 1609), seedless variety of Nagpur orange, high temperature tolerant garden pea (Arka Looking for abbreviations of HYV? High yielding varieties of maize have also proved successful and to a lesser extent new varieties of sorghum. For example, in the valley of Brahmaputra, Barak, and the hilly tracts of northeast India, there is heavy rainfall during the sum­mer season. By Riyo Posted on April 20, 2019. The first irrigation to wheat around the third week of sowing alone raises yield by as much as 30 per cent than that when it is delayed. Proteinase inhibitors have been found very effective in controlling the growth and development of many insects by inactivating serine proteinase enzymes of the insect (Larry and Richard, 2002). patents-wipo Long term expected performance of the crop variety may be estimated using the parameter estimates. Report a Violation, Problems Arising Out of the Diffusion of High Yielding Varieties Seeds, Characteristics of Modern Agricultural Techniques, Rise of Productivity of Crops after the Green Revolution. Wheat yields in Pakistan increased from 4.55 million tons in 1966 (Anonymous, 1966) to 25.48 million tons in 2014 (Anonymous, 2015). The traditional farmers used to harvest green tomatoes, which were then sprayed with ethylene to fetch higher prices than ripe tomatoes; however, there is a substantial decrease in flavor content. Irrigation is thus the single most important input on which de­pends the success or failure of a crop. Content Guidelines 2. In the tra­dition bound Indian society, the efficiency of extension machinery determines largely the efficiency of the producers. Newer approaches are needed to meet the great increase in food production necessitated by population growth in … Irrigation practices have caused salinization and waterlogging of cultivated soils. Without irrigation, a surfeit of other inputs, therefore, is of no avail. Various types of proteinase inhibitors such as potato protease inhibitors II, cowpea trypsin inhibitors(CpTi), etc. High Yielding Varieties Seeds are undoubtedly land substituting, water economizing, more la­bour using, and employment generating innovation; nevertheless, they are very delicate and sensitive and therefore require a great deal of care if a successful harvest is to be obtained. The three new yam varieties were released based on slow rate of oxidation, ability to be eaten in pounded form, high yield, and high dry matter content. Similarly, the Jats, Saini and Gadas of western Uttar Pradesh are more enter­prising and receptive to new innovations in agriculture. The fuller use of inputs may be made only if proper guidance to the cultivators is available. High yielding isn't any one specific method. Kailash C. Samal, Gyana Ranjan Rout, in Genetic Engineering of Horticultural Crops, 2018. It substantially increased food production worldwide and helped to cope with ever increasing hunger of human beings worldwide. They should advance loans to the farmers at a reasonable rate of interest. fruitful - productive or conducive to producing in abundance; "be fruitful and multiply". It supplies the mechanical power to tube wells, pumping sets, threshers, crushers, grinders and chaff cutters. The national average of NPK consump­tion is 75 kg per hectare while in Punjab and Haryana the average consumption of chemical fertilizers in about 170 kg and 110 kg per hectare respectively. A Bt transgenic potato plant resistant to potato tuber moth was developed by transferring the cry1Ab gene under a granule-bound starch synthase promoter (Kumar et al., 2010). Adoption of new needs and intensification of agri­culture in the subtropical countries like India (characterized with er­ratic monsoon) are not possible unless adequate irrigation facilities are available. The infrastructural facilities like transport network, marketing and storage facilities are also very crucial for the successful cultivation of HYV. Varieties for animal feed have wider genetic background and their ratios of Indica and Japonica vary from one variety to another. Relative yield of varieties Trials are conducted using uniform protocols and standard check varieties. Crop pests include weeds, insects, pathogens, and rodents. These dwarf varieties give much higher yields per unit area. HYV can also fetch handsome amounts to the farmers only if a good market for the disposal of the commodity is available within a short distance of the place of production. As a matter of fact, in many cases, man behind the machine becomes more important than the machine itself. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Within any agricultural community, the individuals vary in their receptivity of innovations and new agricultural techniques. You might also want to think about placing a few onions near or around your cucumber plants as studies show that not only will onions keep soil bacteria and insects away, but they increase the cucumber plants overall yield. Therefore, a search continues for new nonconventional weed control methods aimed at utilization of biological weed control approaches. Serine proteinase such as trypsin and chymotrypsin enzymes are present in insect guts for digestion. evolving new high-yield crop varieties中文研究高產作物的新品種…,點擊查查權威綫上辭典詳細解釋evolving new high-yield crop varieties的中文翻譯,evolving new high-yield crop varieties的發音,音標,用法和例句等。 V.A.

HYV - High yielding varieties. For the successful cultivation of HYV, there should be an efficient extension service which may guide the farmers about the various ag­ricultural operations and precautions. Transgenic rice plants with Bt gene have proven to be highly resistant to all lepidopterans, including stem borers such as yellow stem borer, striped stem borer and pink stem borer, and rice leaf folders in field trials. Since the 1970s Chinese farmers have used hybrid rice seed. Excessive rainfall, immediately after the application of chemical fertilizers or that of plant protection chemicals, reduces their utility and effectiveness. The hot and moist environment of the field also becomes conducive for the fast growth and multiplica­tion of insects and pests. Conventional breeding has been an effective means for developing high-yielding varieties; however, it has its own limitations. The storage period of tomatoes could be addressed by a specific approach called RNA-based interference technology or RNAi. Because tomatoes are susceptible to changes in climate, they have autocatalytic activities of ethylene during their ripening period. Buy varieties that say they are compact or “bush” varieties. New crop varieties tolerate disease better, are better adapted to local conditions, and generally produce higher yields. Consequently, the HYV in such areas either could not be diffused or they are not performing satisfactorily. The transgenic “Golden Rice” is another success of genetic engineering. The adopters of HYV must have op­erational capital for the purchase of seeds, installation of tube wells, drilling of pumping sets, chemical fertilizers, plant protection chemi­cals, tractors, harvesters, threshers and other accessories. Many wild species of plants, animals, and microorganisms emerged as pests of crop plants due to destruction of their natural habitats. Globally, yield losses to weeds have reduced with time because of improvements in weed control practices and improved weed management. The evolutionary and taxonomic isolation is thus broken. The problems of crop disease and infestation by insects may also be overcome by timely application of herbicides, fungicides, insecti­cides, nematicides and rodenticides. In order to get a satisfactory agricultural return, the farmer should be in a posi­tion to arrange the costly inputs on time for which sufficient surplus capital should be available. Evaluate varieties for yield consistency from location to location and year to year to ensure for robust, high performance. The Jat farmers who came to India from Pakistan in 1947 were found more industrious and superior in techniques of cultivation in comparison to the other farmers of Punjab, Haryana and Uttar Pradesh. The new seeds are very delicate and highly susceptible to pests and disease. For the application of plant pro­tection chemicals the farmers must have adequate knowledge of plant disease and their controlling chemicals. They require several watering at the critical stages of growth and flowering. For example, the new seeds are less resistant to droughts and floods and need an efficient management of water, chemical fertilizers, insecticides and pesti­cides. This resulted into heavy losses to the farmers of the region. Apart from efficient transport and infrastructural facilities, mod­ern flour mills and rice husking factories need to be located at appro­priate location. This technique in combination with metabolite profiling analysis will be useful for the development and ripening of strawberry fruit (Hoffmann et al., 2006). The irrigation fields enriched with heavy energy input of NPK create a micro climate (hot and humid) in the field which helps in the luxurious growth of plants. In case the farmer does not possess the operational capital, he should have an easy access to credit. The personal qualities of a farmer, his at­titude, beliefs, aspirations, progressiveness, and education, lifestyle and family values determine his capacity to adopt an agricultural innova­tion. These methods have given rise to serious limitations, and their place in sustainable modern agricultural systems is jeopardized.
