Abstract

A field experiment was carried out to study the effect of potassium fertilization on growth, yield, quality, soil fertility and economics of chickpea during rabi 2008-09 to 2010-11. The growth and yield attributes were significantly improved by different potash levels. The application of 20 kg K2O/ ha increase the seed and straw yield significantly over RDF alone and absolute control, however, could not influence significantly over foliar application of KNO3 (2%) twice at flowering and 15 days thereafter. Seed yield of chickpea increases up to 40 kg K2O/ha-1 and further decreases with 50 kg K2O/ha though the difference between them remained at par. The highest uptake of nitrogen, phosphorous and potassium was observed at 40 kg K2O ha-1 which was at par with 30 kg K2O ha-1. The seed protein content increased gradually with increase in potash level and maximum protein content were recorded with application of 40 kg K2O/ha-1 along with physical properties. Available N, P and K status of soil after harvest of chickpea were significantly influenced due to potash levels over initial status. The significantly higher net return was obtained with application of RDF+ 40 kg K2O ha-1 which in turn was found at par with lower level of RDF 30 kg K2O ha-1.
