Effect of Humic Acid with Bio-Regulators on the Yield of Greengram [Vigna radiata (L.) Wikzek]

Continuous adaption of cereal-based cropping system has necessitated other alternatives such as pulses, which constitute a major part in agricultural economy of India. An experiment was conducted at Millet Breeding Station, TNAU, Coimbatore during Kharif (July, 2006 - October, 2006) in CO 6 green gram with nine different treatments. The yield and yield components were significantly increased by the application of chemicals and bioregulators. Various yield components such as days to 50 per cent flowering, days to maturity, number of clusters per plant, number of flowers per plant, number of pods per cluster, number of pods per plant, fertility co-efficient, number of seeds per pod, pod weight per plant, seed weight per plant, seed - pod ratio, pod length, hundred seed weight, grain yield per plot, grain yield per hectare and harvest index were favorably enhanced by the foliar spray of 0.1 per cent humic acid with 0.1 ppm brassinosteroid treatment.
