Response of Sulphur and Iron Application on Growth and Yield of French Bean

A field experiment was conducted at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Prayagraj, UP, during Rabi season 2022 on sandy loam soil. The experiment consists of three levels of Sulphur viz., 15 kg ha-1, 30 kg/ha-1, 45 kg/ha-1 and 3 levels of foliar spray of iron viz., 0.25 % at 20 DAS, 0.50 % at 20 DAS and 30 DAS, 0.75 % at 30 DAS and 40 DAS and control i.e, blanket application of 120-60-50 kg/ha-1 of NPK (farmer's practice), which were replicated thrice. The variety Arka Komal of French bean was sown in November 5th 2022. The results of the experiment revealed that the application of 45 kg/ha-1 of Sulphur along with 0.5 % of iron at 20 and 30 DAS significantly increased the growth parameters viz., plant height (46.43 cm), plant dry weight (27.21 g/plant) and yield parameters viz., pods/plant (16.67), seeds/pod (5.67), seed index (43.65 g), seed yield (1.88 t/ha), stover yield (5.39 t/ha).
