Impact of nano dap on growth, yield and economics of summer pearl millet

Abstract

A field experiment entitled “Impact of nano DAP on growth, yield and quality of summer pearl millet” was carried out on medium black calcareous soil during the summer season of 2024 at Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh (Gujarat). The experiment was laid out in randomized block design with three replications and ten treatments. Application of 75% RDF + seed treatment with nano DAP at 5 ml/kg seed + foliar spray of nano DAP at 6 ml/lit at 20-25 DAS and 40-45 DAS found highest growth parameters, yield parameters and yield in summer pearl millet. Application of 75% RDF + seed treatment with nano DAP at 5 ml/kg seed + foliar spray of nano DAP at 4 ml/lit at 20-25 DAS and 40-45 DAS obtained higher net return in summer pearl millet grown under South Saurashtra Agro-climatic zone. This treatment was closely followed by 75% RDF + seed treatment with nano DAP at 5 ml/kg seed + foliar spray of nano DAP at 6 ml/lit at 20-25 DAS and 40-45 DAS and 100% RDF.
