Response of foliar spray of nano dap and nutrients on growth, yield and quality of chickpea (Cicer arietinum L.)

Abstract

A field investigation entitled “Response of foliar spray of Nano DAP and nutrients on growth, yield and quality of Chickpea (Cicer arietinum L.)” was conducted at AICRP on Integrated Farming System, MPKV, Rahuri, Maharashtra, India during the Rabi season of 2023-24, Mahatma Phule Krishi Vidyapeeth, Rahuri to study the growth, yield and quality attributing characters of chickpea in relation to foliar application of Nano DAP, 12:61:00 and Phosphoric acid in combination with soil application of other sources of phosphorus. The experiment consists of eight treatments viz. T1: Absolute control, T2 : GRDF (FYM @ 5 t ha-1, N:P2O5:K2O @ 25:50:30 kg ha-1), T3 : 100% P2O5 through DAP + One spray of Nano DAP @ 0.25% at 30 DAS, T4: 75% P2O5 through DAP + Two spray of Nano DAP @ 0.25% at 30 and 45 DAS, T5 : 100% P2O5 through DAP + One spray of 12:61:00 @ 1.0% at 30 DAS, T6 : 75% P2O5 through DAP + Two spray of 12:61:00 @ 1.0% at 30 and 45 DAS, T7: 100% P2O5 through DAP + One spray of Phosphoric acid @ 0.25% at 30 DAS, T8: 75% P2O5 through DAP + Two spray of Phosphoric acid @ 0.25% at 30 and 45 DAS. As regards yield attributing characters, significantly higher grain yield (34.56 q ha-1), straw yield (41.59 q ha-1) and biological yield (76.11 q ha-1) were recorded under treatment T5: 100% P2O5 through DAP + One spray of 12:61:00 @ 1.0% at 30 DAS. Significantly the highest gross monetary return (₹ 177791 ha-1) was obtained in 100% P2O5 through DAP + One spray of 12:61:00 @ 1.0% at 30 DAS which also recorded a significantly maximum net monetary returns (₹ 113807 ha-1) and B:C ratio (2.78) than other treatments. While, T1: Absolute control obtained minimum gross monetary returns, net monetary returns and B:C ratio among all the treatments.
