Effect of Plant Density on Performance of Summer Green Gram (Vigna radiata L. Wilczek) Varieties

A field experiment was conducted during summer, 2016 at Agronomy Instructional Farm, C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat to study the Response of different greengram (Vigna radiata L. Wilczek) cultivars to varying plant populations Nine treatment combinations comprising of three plant densities (main plot) viz. , 4.44 lakh plants/ha (P1) (22.5 cm × 10 cm), 3.33 lakh plants/ha (P2) (30 cm × 10 cm) and 2.22 lakh plants/ha (P3) (45 cm × 10 cm) and three varieties (sub plot) viz. , Meha (V1), GM 4 (V2) and GAM 5 (V3) were evaluated in split plot design with four replications. Results revealed that greater plant height was obtained from plant density of 3.33 lakh plants/ha, which was closely followed by plant density of 4.44 lakh plants/ha. Number of branches/plant, pod length and number of seeds/pod were significantly higher under plant density of 2.22 lakh plants/ha followed by plant density of 3.33 lakh plants/ha. Number of pods/plant was significantly higher under plant density of 2.22 lakh plants/ha. Highest seed and stover yield were recorded under plant density of 3.33 lakh plants/ha whereas stover yield was at par with plant density of 4.44 lakh plants/ha. Higher protein yield was found under plant density of 3.33 lakh plants/ha which was at par with planting density of 4.44 lakh plants/ha. The variety GM 4 took significantly lower number of days to 50 per cent flowering and physiological maturity and produced highest number of pods/plant, seed index, seed yield and stover yield. The highest protein content was recorded in variety Meha which was at par with variety GAM 5 where as variety GM 4 gave significantly higher protein yield which was statistically at par with variety GAM 5. VMaximum gross income and net income along with higher BCR value were recorded with plant density of 3.33 lakh plants/ha and variety GM 4.
