Производитель: "LAP Lambert Academic Publishing" Rice is a major crop that is grown in more than 110 countries. The total area planted under rice in India is 44. 0 million hectares which is largest in the world against a total area of 156. 6 million hectares. The average yield of rice in India is 3. 2 tonnes/hectare alone. The reasons for low yield are limited area under irrigation, seasonal shortage of resources and delay in land preparation and transplanting. A study on economics and major constraints in rice cultivation in Kaithal district of Haryana was conducted during 2009-10. Total costs in rice production amounted to be Rs. 33778. 68/ha. Average yield was 4. 99 t/ha. Benefit-cost ratio worked out to be 1. 27. Pests and disease incidence, lack of remunerative price and labour shortage were the major constraints in rice production.
