Abstract:
The present investigation was carried out during 2017-18 and 2018-19 at Research farm, Indira Gandhi Krishi Viswavidyalaya, Raipur to evaluate the “Influence of rice establishment method on Nutrient use efficiency and Water use efficiency in chickpea under rice- pulse cropping system in a Vertisols. Influence of rice establishment method and water and nutrient management practices in chickpea under rice- chickpea cropping system on nutrient use efficiency and water use efficiency in post rice, chickpea crop were evaluate. Nutrient use efficiency, physiological efficiency, internal efficiency, recovery efficiency and partial factor productivity of nitrogen under chickpea was found significantly higher under direct seeded rice than puddled and unpuddled transplanted rice establishment method. Water use efficiency was found significantly higher in direct seeded rice establishment method. Under rice chickpea cropping system, on the basis of nutrient use efficiency, agronomic efficiency, physiological efficiency, internal efficiency, apparent recovery, partial factor productivity and water use efficiency, the performance of direct seeded rice establishment method was best during rabi followed by unpuddled transplanted rice. Direct seeded rice establishment method of rice followed by unpuddled transplanted rice for chickpea proved to be more remunerative as compared to the other treatments as above fact.
