Efficacy of Fungicidal Seed Treatments on Growth and Yield Parameters of Green Gram

Abstract

The experiment was conducted to perceive the effect of fungicidal seed treatment on growth and yield parameters of green gram cv. GM-3 with nine different fungicides. The results revealed that dry seed treatment with either mix formulation of carbendazim+mancozeb or thiophanate methyl or carbendazim @ 2.5 g kg-1 seeds is very effective in field to get maximum seed germination, better plant growth, root growth, yield parameters and yield. Seed germination was maximum in dry seed treatment with carbendazim + mancozeb (83.85%) which was statistically at par with thiophanate methyl (83.58%), carbendazim (82.53%) and captan (80.77%). Plant height was maximum in dry seed treatment in mixed formulation carbendazim+mancozeb (41.53 cm) which was statistically at par with thiophanate methyl (39.91 cm), carbendazim (39.67 cm) and captan (37.00 cm). Average numbers of pods plant-1 were maximum in dry seed treatment with carbendazim+mancozeb (12.33) which was statistically at par with thiophanate methyl (12.17), carbendazim (11.90), captan (11.85), thiram (11.58) and difenconazole (11.09). Average numbers of seeds pod-1 was maximum in dry seed treatment with carbendazim+mancozeb (7.58) which was statistically at par with thiophanate methyl (7.48), carbendazim (7.31), captan (7.28) and thiram (7.12). The pooled data of two years indicated that grain yield was significantly higher in dry seed treatment with carbendazim + mancozeb (818.40 kg ha-1) as compared to the rest but was statistically at par with thiophanate methyl (790.73 kg ha-1) and carbendazim (771.35 kg ha-1) followed by all the other treatments.
