Economic feasibility of applying foliar nutrition in guava (Psidium guajava L) cv Sardar L-49

A field experiment was carried out to study the response of guava (Psidium guajava L) cv Sardar L-49 to foliar application of micronutrients viz zinc, iron and boron in different combinations for economic feasibility. The results revealed that the application of zinc, iron and boron increased the net realization in guava. The treatment zinc sulphate (0.5%) + ferrous sulphate (0.5%) + borax (0.3%) gave maximum net realization of Rs193314. The foliar spray of Zn, Fe and B increased cost/benefit ratio in guava. The same treatment resulted in highest cost/benefit ratio (1:4.39) as compared to other treatments and found to be most economical while lowest cost/benefit ratio (1:2.72) was  found in treatment zinc sulphate (0.5%) alone.
