Impact of phosphorus, sulphur and seaweed sap on yield and economics of chickpea (Cicer arietinum L.)

A Field experiment was conducted during two consecutive rabi seasons viz. 2012-13 and 2013-14, to assess the response of different phosphorus, sulphur and seaweed sap (prepared from Kappaphycus alvarezzi and Gracilaria sp.) levels on growth, yield and nutrient uptake of chickpea. The results reveal that application of phosphorus fertilizer at 40 and 60 kg/ha significantly increased the grain, haulm and biological yield in chickpea. Application of sulphur at 20 and 40 kg/ha significantly influenced the economic parameters. Seaweeds sap sprays at 10 % also significantly enhanced the economics of chickpea. Applications of 40 kg phosphorus, 20 kg sulphur and 10 % seaweed sap spray recorded better yield, net return and B:C ratio.
