Influence of organic and inorganic amendments on growth parameters of black gram

Abstract

A study was undertaken to assess the influence of organic and inorganic amendments on growth parameters of black gram. The results from the experiment revealed that the various organic and inorganic amendments added to the soil had significantly influenced the germination percentage in black gram. Among the various amendments added to the soil, it was observed that application of Spent Wash @ 5.0 lakh litres ha-1 (T6) recorded the highest germination percentage and Leaf Area Index of 93 and 4.84% respectively which was followed by T7 (Pressmud @ 8 tonnes ha-1) recording 82 and 4.33% respectively. Among the various amendments added to the soil, it was observed that application of Spent Wash @ 5.0 lakh litres ha-1 (T6) recorded the highest root length and shoot length of 7.7 and 11.54 cm respectively which was followed by T7 (Pressmud @ 8 tonnes ha-1) recording 6.2 and 10.82 cm respectively. Based on the present study, it can be concluded that application of spent wash @ 5.0 lakh litres ha-1 significantly influenced the growth parameters of black gram.
