The Productivity and Nutrient Use Efficiency of Rice–Rice–Black Gram Cropping Sequence Are Influenced by Location Specific Nutrient Management

Nutrient management is critical for rice farming because the crop grown under diverse conditions, and in most cases, existing nutrient practices fail to achieve an attainable yield target. During recent years site specific gained importance a target with maximum use efficiency. Sufficient research work has not been carried out this direction so far rice–rice–pulse (black gram) sequential cropping system red lateritic belt of West Bengal, India. A multi-locational field experiment was conducted from July 2013 June 2015 at three different locations, namely, Guskara (Burdwan district) Benuriya (Birbhum villages farmers’ fields university farm Visva-Bharati, Sriniketan, The performance nutrients tested by providing ample doses N, P, K, S, Zn compared omission these nutrients. growth parameters, such as biomass production, leaf area index, number tillers, attributes were influenced treatments. Application 100% resulted its superiority other options studied, similar trend also noted treatment expression efficiency (NUE) response (NR). available contents soil increased steadily due increase fertilizer application. study concluded that optimization NPK on along need-based S application beneficial higher productivity.
