Abstract

A field study was carried out during summer season (2011) with the objective to assess the physiochemical and root parameters of seven blackgram genotypes under rainfed situation as influence by foliar feeding with boron. There were three treatment combinations comprising of control (T1), foliar application of 100 ppm boron at 20 DAS (T2) and foliar application of 100 ppm boron at 20 and 35 DAS (T3). Significant variations in root parameters, physiological and biochemical parameters were recorded in all the genotypes. Genotype USJD-113 followed by SB-121-36 was recorded to be the best genotypes in terms of physiological parameters like photosynthetic rate, chlorophyll contents, leaf nitrogen content and root characters. Foliar application of boron caused significant alteration in root parameters, physiological and biochemical parameters of all the genotypes. The treatment T3 was found to be more effective in enhancing all the parameters as compared to T2. Genotypes USJD- 113 and SB-121-36 were found to be more responsive towards foliar application of boron.
