The present study analysed the temporal pattern in India's rice production and sources of productivity growth. The study used data from the cost of cultivation surveys for 10 major rice-producing states for the period 1990/91–2012/13 for analysing the sources of productivity growth. The ...
In Asia, more than two billion people are getting 60–70 per cent of their energy requirement from rice and its derived products. Total geographical area under rice in India is 43.73 million hectares with annual production of 106.19 million tones with productivity 2.46 tons per ha in 2013–...
Crop intensification, that is, increasing productivity on existing cropland, can help reduce the need for costly food imports and/or relieve pressure on land conversion for agriculture10,11,18,19,20,21,22,23. In the case of rice in Africa, there is a clear opportunity for increasing product...
Zinc nutrition in rice production systems: a review Background Zinc (Zn) deficiency is one of the important abiotic factors limiting rice productivity worldwide and also a widespread nutritional disorder af... Hafeez-ur Rehman,T Aziz,M Farooq,... - 《Plant & Soil》 被引量: 129发表: 2012...
Increased use of irrigation and nitrogen (N) in rice and wheat would increase productivity. It would also enhance the emission of greenhouse gases from soil causing global warming and climate change. This study quantified the trade-offs between increased production with N fertilizer and irrigation ap...
The abundant supply of agroclimatically suitable wetlands (~239 million ha) and water resources can support a large expansion in rice area and productivity. Currently, less than 5% of the potentially suitable wetlands are planted with rice because of various constraints. Expansion and intensification ...

Research farm, Hyderabad, India, to compare the influence of organic and conventional farming systems on productivity of fine grain rice varieties, cumulative partial nutrient balance, and soil health/quality in terms of nutrient availability, physical and biological properties, and sustainability index....
A total area of about 13.5 million of hectares sustain this system, corresponding to about 50% of all grains produced in India [3]. However, a slowdown in the increase in productivity of the rice–wheat systems has been observed in the last decades, which has generated concern for the ...
Organic fertilizer application is needed to replace nutrients recovered by crops from the fields in order to restore the crop production potential of the soil. The utilization of chicken manure as an organic fertilizer is essential in improving soil productivity and cop production. In Malaysia, ...
