The field investigation entitled “Effect of plant geometry and fertilizer levels on yield and economicsof cowpea (Vignaunguiculata L. Walp)” was conducted at Department of Agronomy, College of Agriculture, Latur. The experimental field was levelled and well drained. The soil was clay loam in texture, low in available nitrogen, very low in available phosphorus, very high in available potassium and moderately alkaline in reaction. The environmental conditions prevailed during experimental period was favourable for normal growth and maturity of cowpea crop. The experimental plot was laid out in a Factorial Randomized Block design (FRBD) with four spacing and three levels of fertilizer which comprises twelve treatment combinations. Each experimental unit was repeated three times. The gross plot size of each experimental unit was 5.4 x 4.5 m2 and net plot size was 4.8 × 3.5 m2(S1), 4.8 × 3.6 m2(S2), 4.5 × 3.5 m2(S3), 4.5 × 3.6 m2(S4)respectively. Sowing was done on 4th July, 2013 with four spacingviz.30 x 10 cm2 (S1), 30 x 15 cm2(S2), 45 x 10 cm2 (S3), 45 x 15cm2 (S4) and three levels of fertilizerviz.30:60:00 NPK kg ha-1, 25:50:00 NPK kg ha-1 and 20:40:00 NPK kg ha-1 as per treatments. Sowing was done by dibbling method. Cowpea crop grown in kharif season produced significantly higher seed yield, straw yield, gross monetary return, net monetary return and benefit cost ratio of cowpea crop was observed with the wider spacing 45 x 10 cm2. The higher seed yield, straw yield, gross monetary return, net monetary return and benefit cost ratio was obtained due to higher fertilizer level i.e. application of 30:60:00 NPK kg ha-1. The interaction effects of spacing x fertilizer levels were found non-significant.
