Effect of basal and foliar application of boron and zinc on yield attributes in Solanum melongena L.

Abstract

Field experiments were conducted during 1999-2000 and 2000-2001 to study the effect of basal application (BA) of zinc sulphate (5 and 10 mg kg - i soil) or boric acid (1 and 2 mg kg -1 soil) alone or foliar applications (FA) of water or 1% ZnSO 4 or 1% H 3 B0 3 or the combinations of both BA and FA of either ZnSO 4 or H 3 B0 3 on yield attributes (number of flowers and fruits/ plant, fruit weight, size and total yield). On the basis of the two-year data, it was found that all the treatments of BA as well as FA enhanced yield attributes but the combination of BA of 10 mg kg --1 soil ZnSO 4 and FA of 1% H 3 B0 3 gave highest yield as compared to other treatments and control plants.
