Yield and Yield Component Responses of Vegetable Crops to Farmyard Manure Rates in the Presence of Inorganic Fertili

Abstract

Results indicated the need for use of organic manures even when a high rate of NPK fertilizer was applied. Farmyard manure (FYM) benefitted fruit set in egg plant and generally enhanced size characters in both onion and eggplants. FYM helped to increase the proportion of grade one onions, especially at relatively high plant densities. Increasing plant density increased yield per hectare, but decreased productivity per plant. Yield increase per hectare was therefore largely dependent on number of plants contributing to yield and, in eggplant, also on the number of fruits set per plant.
