Increasing rice yield potential

The results of resreach showed that rice areas were not distributed relatively uniform in all districts and the rice yield had average level when compared with the other rice cultivation areas. Rice yields in Thai Nguyen province sharply increased from 4.87 tons/ha (2010) to 5.49 tons/ha (2020) with the slightly decreasing the rice areas, it is proved that the farmer was not concerned to increase the planting areas while they focused on rising the yield potential and quality.

Micronutrients are not only essential for plant growth and development but are also integral to human health. Fe and Zn deficiencies cause serious nutritional problems in human beings. Increasing the micronutrient content of grain by bio-fortification offers great potential to combat micronutrient deficiency and dramatically impact human health. To find out the most suitable and profitable method of bio-fortification in aromatic rice with Zinc and Iron, a field experiment was conducted during kharif, 2019 at the Research Farm, Bihar Agricultural University, Sabour, Bhagalpur.

Rice is staple food for more than half of the world’s population. The fast growth of the world population demands an increase of 26 % in rice production to fulfill the requirement. The rice blast caused by Magnaporthe oryzae is considered to be the most significant and potentially damaging rice disease in the world and has been responsible for 35 to 50 % global loss in rice yield causing serious constraint in global food supply.

Conservation agriculture is a potential solution for increasing yield in wheat crop in the rice wheat cropping system. A study was carried out to assess the impact of the conservation practices in rice-wheat cropping system. The experiment was conducted at the PAU, Ludhiana during 2010-2013. The design of an experiment was split-plot with 12 treatments and 3 replications.

A long-term field experiment was conducted to design and implement alternative production systems with increased resource use efficiency, productivity and to determine the effect of tillage systems and mineral fertilizers on soil organic carbon patterns. This experiment intended to evaluate the effects of these management strategies on soil structural formation and structural stabilization of a sandy loam soil. The shift from puddled - transplanted rice on the flat land to raised bed systems affects the productivity and resource use efficiency of the rice-wheat system.

Maize is the 3rd most important crop in the Bihar next to rice and wheat. It is grown throughout the year in one or other part of state. Due to continuous cropping of maize and other factors like improper use of fertilizers, pesticides and climate change, the disease problem has increased in tremendous proportion. Almost all parts of the maize plant are susceptible to numerous diseases that considerably reduce the yield and quality of the crop.

Rice is one of the most important food crops that feed over half of the global population and biggest consumer of fresh water diverted from irrigation. Water scarcity is burning issue of agriculture, outcome of climate change and unpredictable rainfall. It threatens the future of irrigated rice cultivation. Researchers developed new technology called ―Aerobic Rice‖ to cope up with present situation. Rice is grown in well-drained, non-puddled and non-saturated soils. Aerobic rice cultivar has drought tolerance capacity as well as yield potentiality.

The accumulation of Cr in soil is a major concern because of its possible phytotoxicity or increased movement of metals into food chain and the potential for surface and ground water contamination. Excessive metal accumulation in contaminated soil can result in decrease in soil microbiological activities, soil fertility and overall soil quality which may lead to reduction in yield.

Rice is sensitive to high temperature, especially at the reproductive stage, which causes spikelet sterility and yield losses. The increase in both frequency and intensity of high temperature, along with its large variability, is emerging as a potential threat to the sustainability of rice production. The predicted 2–4°C increment in temperature by the end of the 21st Century poses a threat to rice production.

Rice based production systems in the sub-humid region (Purvanchal) of Uttar Pradesh are traditional, with low yield and low farm income, and they have largely missed out on the benefits of the Green Revolution. To enhance productivity, alleviate environmental and management constraints, and enhance farmers’ income in the rice–wheat cropping system of the sub-humid Purvanchal region, Uttar Pradesh, new approaches that are more productive and sustainable need to be developed.

System of Finger millet intensification or SRI-finger millet cultivation is a method of cultivating finger millet by applying cultivation principles adopted in SRI (System of Rice Intensification) in order to get higher productivity. This method is also called as Guli type of Planting. This POP developed for SRIFinger Millet is an integration of the farmers’ practice and standard practices of finger millet cultivation along with two levels of two doses of fertilizers.

Increases in rice grain yield depend on introduction of potential cultivars including hybrids into Andaman and Nicobar islands that with small acreage (5340 ha) won’t merit developing hybrids locally. The objective of this study was to evaluate newly released hybrids and high yielding varieties of rice elsewhere in the country and identify promising ones for augmenting the huge production shortages in the islands.

Rice-Wheat cropping system pre-dominated in the India covering an area of about 10.5 million hectare. Adverse effect of continuous puddling in rice field forced scientists to search for other methods of rice establishment like direct seeding; machines transplanted and dry seeding with ZT machine and wheat by zero tillage etc. In a 3‐year study, we assessed the effects of crop establishment methods in participatory mode on farmers’ field through on farm on productivity and profitability in a rice–wheat (RW) system at Basti, Siddharthnagar and Gorakhpur district of U.P.

Chhattisgarh, the 26th state of the Indian Union came into existence on November 1st, 2000. In Chhattisgarh, maize is a kharif season crop and second most important crop next to paddy in terms of both area and production. The state has got very good potential for maize but the productivity is very low due to cultivation of open pollinated varieties (OPVs) and improper input management practices. The real potential can be realized by the adoption of hybrid maize especially single cross hybrids with full package of practices.

The agricultural sector faces daunting challenges because of climate change, particularly amidst increasing global water scarcity, which threatens irrigated lowland rice production. By 2025, 15-20 million ha of irrigated rice is estimated to suffer from some degree of scarcity. Rice systems provide a major source of calories for more than half of the world‟s population; however, they also use more water than other major crops. Irrigated lowland rice not only consumes more water but also causes wastage of water resulting in degradation of land.
