Effect of Customized Fertilizer Application on Physiological Aspects of Chickpea (Cicer arietinum L.)

It is predicted that India will required around 32 million tons of pulses to feed around 1.68 billion people by 2030. Therefore, improved technologies must be needed to increasing production. And increase in physiological efficiency of crop is important to improve the productivity and production of crop. Hence, the experiment entitled "Effect of customized fertilizer application on physiological aspects of chickpea (Cicer arietinum L.)" was carried out at Department of Plant Physiology, AB & MAP, College of Agriculture, IGKV, Raipur (Chhattisgarh) during rabi 2020-21. The experiment consists of five treatments with replicated four times in RBDS design and Indira chana 1 variety of chickpea used as a test crop. The study highlighted that that the T5 CFG 3 (NPKSZnMo 5.5:4.6:4.5:8.3:1.4:0.034 %) based on recommendation (125%) was found effective to minimize the phenophase like 50% flowering, physiological maturity significantly. Higher chlorophyll value was observed in T5 CFG 3 (NPKSZnMo 5.5:4.6:4.5:8.3:1.4:0.034 %) based on recommendation (125%) and Maximum Fv/Fm (chlorophyll florescence) was observed in T4 CFG 2 (NPKSZnMo 5.5:4.6:4.5:8.3:1.4:0.034%) based on recommendation (75%). T3 CFG 1 (NPKSZn Mo5.5: 4.6:4.5:8.3:1.4:0.034%) based on recommendation (100%) was also observed effectively increased dry matter partitioning towards the economic sink and maximize Crop growth rate, Relative growth rate, economic (seed) yield, biological yield and harvesting index. Thus, it is proved that in comparison with the recommended doses of fertilizers application of CFGA has enhanced the plant yield.
