Effect of organic manures in germination and vegetative growth of black gram (Vigna mungo L.)

Abstract

The efficiency of different organic manures on germination and vegetative growth of black gram was evaluated. A total of five organic manures were used for the study viz., vermicompost, FYM, poultry manure, rice husk compost and wood ash compost. It was thoroughly mixed with soil in the ratio 2:1. The experiment was laid out in Completely Randomized Design (CRD). Different parameters such as germination percent, time required for germination, plant height, number of leaves per plant and root length were taken into account. Among all the treatments, soil + poultry manure showed the best results in all aspects. The highest germination percent was observed in case of soil + poultry manure i.e., 93.75 percent. The minimum time required for germination was 1.5 days in treatment soil + poultry manure. The mean germination rate was observed to be highest in treatment soil + poultry manure i.e., 0.67. The plant height was observed to be highest in soil + poultry manure with value 42.62 cm. The number of leaves was observed at 35 days after sowing and was found to be highest in treatment soil + poultry manure i.e., 18.70 numbers. The root length during vegetative growth of black gram was observed at 35 DAS and was found to be longest in soil + poultry manure with value 38.60 cm.
