Impact of TNAU Pulse Wonder on Physiological and Yield Parameters in Blackgram (Vigna mungo)

Investigations were undertaken to study the effect of pulse wonder on growth and productivity of black gram variety CO 6. Morphological and growth characters were measured at seven days after the foliar application of MAP and Pulse wonder and physiological and biochemical parameters were estimated at seven days after the foliar application of MAP and Pulse wonder of green gram. The number of pods per plant and yield per plant were assessed at the time of harvest of green gram. The foliar application of pulse wonder @ 2 kg per acre favourably influenced the shoot length and root length. The number of leaves was increased due to foliar application of pulse wonder @ 2 kg per acre. Increase in the total dry matter production was recorded by the foliar spray of pulse wonder @ 2 kg per acre in black gram. There was also increase in the Leaf Area Index (LAI) and chlorophyll Stability Index of the leaf due to foliar spray of pulse wonder @ 2 kg per acre in black gram. The biochemical constituents such as soluble protein content and the activity of nitrate reductase were also greatly enhanced by the foliar spray of pulse wonder @ 2 kg per acre treatment in black gram. The number of pods per plant was significantly increased by the foliar application of pulse wonder @ 2 kg per acre in black gram. The overall results as evidenced by the yield per plant in black gram revealed that foliar spray of pulse wonder @ 2 kg per acre is advantageous and can be recommended for foliar application by the farmers to increase the black gram production and productivity.
