Abstract:
A field experiment was conducted during 2022-23 Kharif season at Regional Agricultural Research Station, Vijayapura to study the influence of zinc and iron on growth and yield of mothbean. The experiment was laid out in a split plot design with four levels of zinc in main plot (0, 2.5, 5 and 7.5 kg ha^-1) and four levels of iron in sub plot (0, 2.5, 5, 7.5 kg ha^-1) with one absolute control. Application of zinc sulphate alone @ 7.5 kg ha^-1 and iron sulphate alone @ 7.5 kg ha^-1 recorded maximum plant height, dry matter accumulation, number of pods per plant, test weight, grain yield, straw yield, nutrient content of zinc, iron and uptake of zinc and iron of mothbean. The combined application of zinc sulphate and iron sulphate each @ 7.5 kg ha^-1 recorded no significant difference however, numerically higher values of growth parameters, yield parameters and nutrient uptake of mothbean was noted. All the growth, yield parameters and nutrient uptake increased with increase in zinc sulphate and iron sulphate levels.
