Effect of iron and zinc on growth and yield of French bean in iron and zinc deficient inceptisol soil

Abstract

A field experiment was conducted at National Agriculture Research Project, Ganeshkhind, Pune (M. S.) on french bean (cv. Phule Suyash) during kharif 2017 to study the effect of iron and zinc on growth and yield of french bean on iron and zinc deficient inceptisol with eleven treatments and three replications. Among the various treatments the application of GRDF + soil application of FeSO4 @ 15 kg ha-1 + ZnSO4 @ 10 kg ha-1 significantly increased yield contributing parameters viz. number of branches plant-1, number of green pods plant-1, green pod weight, green pod length, green pod breadth. The green pod yield were increased due to application of GRDF + soil application of FeSO4 @ 15 kg ha-1 + ZnSO4 @ 10 kg ha-1 and it was closely followed by GRDF + three foliar sprays of each chelated iron + chelated zinc @ 0.2 % at 25, 40 and 55 days after sowing. The chlorophyll and protein content was also increased as that of yield due to application of GRDF + soil application of FeSO4 @ 15 kg ha-1 + ZnSO4 @ 10 kg ha-1 followed by GRDF + three foliar sprays of each chelated iron + chelated zinc @ 0.2 % at 25, 40 and 55 days after sowing.
