Nutrient management in wheat - mustard intercropping system with different row proportion

Abstract

Field experiment was conducted at Main Agricultural Research Station, Dharwad in split plot design whichcomprised of four row proportion as main plots and two fertilizer levels as sub plots. The experiment was conducted todetermine the effect of wheat –mustard row ratio and to find out the optimum doses of fertilizer in intercropping systemon growth and yield of wheat-mustard. The treatment detail comprise of wheat-mustard in different row proportions viz.,5:1, 4:1,3:1, and 4:2 and fertilizer level include 100 and 125% RDF. The results of the study revealed that significantlywheat grain yield (2,942 kg/ha) was recorded in wheat –mustard 5:1 row proportion and higher mustard seed yield (1,197kg/ha) was recorded in wheat –mustard 4:2 row proportion . Application of 125% RDF recorded significantly higher wheatgrain yield ( 2,742 kg/ha) and mustard seed yield (1075 kg/ha). It can be concluded that wheat-mustard in 5:1 rowproportion with 125% RDF recorded significantly higher wheat equivalent yield (4746 kg/ha) and higher land equivalentratio (1.35) as compared to other row proportions and fertilizer level.Similarly higher gross returns ( 1,18976) net returns( 80,910 ) and BC ratio (3.13) were obtained in wheat-mustard 5:1 row proportion with 125% RDF
