ABSTRACT

Two organic composts i.e. green manure (GM) and farmyard manure (FYM) were added to the soil at three concentrations i.e. C1= 1%, C2=5%, and C3=10%, to amend topsoil. Results revealed that increase in amendment’s concentrations to 10% decreased the chance of plant survival to 68.06% while maximum (89.72%) number of plants survived for 1% amendments concentration. Significantly high number (87.22) of plants survived for green manure as compared to FYM with 78.47. C2 amended was found to be best with lowest (1.19) disease ratings. Significantly higher (i.e. 1.75 and 1.89) disease was observed for C1 and C3 amended soils. FYM was better as it produced significantly less (1.14) disease as compared to green manure with 1.35 disease severity. On the other hand, among concentrations, 5% was the best yielding with 2.17kg plant-1, while the other concentrations i.e. 1% and 10% gave statistically similar and less yield (1.83 and 1.77kg plant-1, respectively). Thus, it was concluded, that the application of green manure compost (used in 1% and 5% V/V concentration) to the soil, suppress the disease more and produced more yield than FYM-treated plants, however, the higher concentration i.e., 10% soil amendments had negative effect.
