Effect of fertility on growth, yield and economics of sunflower, Helianthus annuus L

摘要

Sunflower responds to fertilizer application for high yield.Singh et at. (1999) reported that the sunflower hybridsrequire more nutrients than the varieties. This adds toadditional expenditure. On the other hand, if the hybridsare not fertilized with optimum level of nutrients then thesoil available nutrients may be greatly depleted. Thisrequires a comparative study on the relative performanceof a variety and hybrid grown under rainfed condition withdifferent levels of fertilizers. Hence, this experiment wasplanned.
