INFLUENCE OF SPACING AND SCHEDULING OF IRRIGATION ON GROWTH, YIELD, YIELD ATTRIBUTES AND ECONOMICS OF SUMMER GREENGRAM (VIGNA RADIATA L.)A.N. Chaudhary , K.J. Vihol , J.H. Chaudhary, V.B. Mor and L.J. Desai
A field experiment was carried out during the summer season of the year 2013 to study the Influence of spacing and scheduling of irrigation on growth, yield and yield attributes of summer green gram (Vigna radiata L.). The plant height at harvest significantly influenced and recorded highest under treatment I3 (1.0 IW:CPE ratio). Number of branches plant-1 was significantly the highest, while number of pods plant-1, pod length, number of seeds pod-1, seed yield (1107 kg ha-1) and stover yield (1970) were observed significantly higher under the irrigation treatment of I3 (1.0 IW:CPE ratio) followed by I2 (0.8 IW:CPE ratio). In case of spacing, the number of branches plant-1, number of pods plant-1, number of seeds pod-1 were significantly higher under treatment S1 (30 x 10 cm) followed by treatment S10 (22.5 x 10 cm). An interaction effect between irrigation schedule and spacing levels on number of pod plant-1 and seed yield were found to be significantly higher under treatment combination I3S1 (1.0 IW/CPE ratio with 30 x 10 cm spacing) followed by treatment combination I2S1 (0.8 IW/CPE ratio with 30 x 10 cm spacing). Treatment combination I3S1 (1.0 IW:CPE ratio with 30 x 10 cm) registered highest net realization of Rs. 49118 ha-1 with BCR value of 1:3.14 followed by treatment combination I2S1 (0.8 IW:CPE ratio with 30 x 10 cm).
