Abstract
A field experiment was conducted in the farmer’s field at Vijaypura, Bangalore Rural District, to study the effect of soil and foliar application of zinc on the growth, yield, and economics of Knol khol. The experiment was laid out in a randomized complete block design with 10 treatments replicated thrice. Results of the study indicated that the combined application of zinc to the soil and foliage significantly enhanced the growth and yield parameters of Knol khol. Significantly higher plant height (39.90 cm), number of leaves per plant (14.83), leaf length (19.68 cm), and yield (23 t ha-1) were recorded in the treatment T9, which received RDF and FYM along with 4 kg of zinc through ZnSO4 as soil application and 0.14% zinc through zinc sulfate as a foliar spray. Also, higher benefit-cost ratio of 3.48 was recorded in the same treatment.
