Effect of phosphorus, sulphur and seaweed sap on growth, yield and nutrient uptake of chickpea (Cicer arietinum L.)

Field experiment was conducted during two consecutive rabi seasons in India in 2012–13 and 2013–14 to assess the response of different seaweed saps (prepared from Kappaphycus alvarezzi and Gracilaria sp.), phosphorus and sulphur levels on growth, yield and nutrient uptake of chickpea. The results revealed that P fertilization at 40 and 60 kg/ha significantly increased the yield components viz., pods/plant, grains/pod, grains/plant, grain yield/plant 100-grain weight, grain yield, haulm yield and biological yield. The application of sulphur at 20 and 40 kg/ha significantly influenced the yield parameters. Seaweed sap sprays at 10% significantly enhanced the yield attributes and yield of chickpea.
