 ABSTRACT

The pulses are an important source of nutritional security with cereals to mitigate malnutrition in undeveloped and under-developing countries. An experiment was conducted to study the effect of foliar application of six growth regulators viz., Indole acetic acid (600 ppm), Ethrel (250 ppm), Gibberellic acid (30 ppm), Thiourea (500 ppm), Salicylic acid (100 ppm) and Naphthalene acetic acid (40 ppm) and two micronutrients viz., Boron (0.5%) and Ferrous sulphate (0.5%) at two growth stages (30 and 45 DAS) in black gram cv. LBG-625 on seed quality. The results revealed that foliar application of gibberellic acid recorded significantly higher test weight (59.03 g), germination (88.10 %), seedling vigour index I & II (2,531 and 514), total dehydrogenase activity (0.440 OD at A480 nm), protein (24.96%), field emergence (85%), electrical conductivity (275.48 dSm-1), mean seedling length (28.72 cm), seedling dry weight (5.84 mg) and seed mycoflora (16.00%) in comparison to control. Foliar application is ultra-efficient when roots are incapable of absorbing the required amount of nutrients from the soil.

Key words: Black gram, Growth regulators, Micronutrients, Seed quality, Seedling vigor index.
