Effect of iron and zinc on growth and yield of buckwheat (Fagopyrum esculentum L.)

The field experiment was conducted during Rabi season 2024 at Crop Research Farm, Naini Agricultural Institute, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, U.P. To determine “Effect of Iron and Zinc on growth and yield of Buckwheat (Fagopyrum esculentum L.)’’ The experiment was laid out in Randomized Block Design with ten treatments which are replicated thrice on the basis of one year experimentation are T., Iron 5 kg/ha + Zinc 15 kg/ha, T₂., Iron 5 kg/ha + Zinc 20 kg/ha, T₃., Iron 5 kg/ha + Zinc 25 kg/ha, T₄., Iron 10 kg/ha + Zinc 15 kg/ha, T₅., Iron 10 kg/ha + Zinc 20 kg/ha, T₆., Iron 10 kg/ha + Zinc 25 kg/ha, T₇., Iron 15 kg/ha + Zinc 15 kg/ha, T₈., Iron 15 kg/ha + Zinc 20 kg/ha, T₉., Iron 15 kg/ha + Zinc 25 kg/ha, T₀.,Control 40-20-20 : N-P-K kg/ha. The result showed that significantly maximum plant height (73.60 cm), plant dry weight (11.03 g/plant), grains per plant (245.56), grain yield (1650 kg/ha), stover yield (4610 kg/ha), were recorded in T₄., [ Iron (10 kg/ha) +Zinc (15 kg/ha)] as compared to other treatments. Similarly, maximum gross returns (INR 147770/ ha), net return (INR 92745/ha) and benefit cost ratio (1.69) was obtained in the T₄ [Iron (10kg/ha) +Zinc (15 kg/ha)] as compared to other treatments.
