Effect of row proportion and nutrient management on growth, yield and economics of pigeonpea(Cajanus cajan (L.) Millsp.) and kodo millet [Paspalum scrobiculatum] intercropping system

Abstract

An agronomic investigation entitled “Studies on row proportion and nutrient management in pigeonpea [Cajanuscajan (L.) Millsp.] and kodo millet [Paspalum scrobiculatum] intercropping system” was carried out at Agricultural CollegeFarm, Raichur during kharif 2021. The experiment was laid out in randomized block design with three replications and tentreatments. Results revealed that, the sole crops of pigeonpea and kodo millet produced significantly higher seed and grainyield (1298 and 2015 kg ha-1, respectively) when compared to their intercropping treatments. Among the different intercroppingtreatments, T4 [pigeonpea+ kodo millet (1:1) with 125 per cent RDF to pigeonpea and no fertilizers to kodo millet] recordedsignificantly higher seed yield of pigeonpea (1101 kg ha-1) and T10 [pigeonpea+ kodo millet (1:2) with 100 per cent RDF topigeonpea and 100 per cent RDF to kodo millet] recorded significantly higher grain yield of kodo millet (1878 kg ha-1).Thehigher net returns was recorded under T6 [pigeonpea + kodo millet (1:1) with 100 per cent RDF to pigeonpea and100 per cent RDF to kodo millet] (`88,698 ha-1). The treatment T5 [pigeonpea + kodo millet (1:1) with 100 per cent RDFto pigeonpea and 50 per cent RDF to kodo millet] recorded significantly higher benefit cost ratio (4.54).
