Abstract

A field experiment was conducted at the Agronomy Instructional Farm, C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to investigate the “effect of foliar nutrition on yield, quality, nutrient content and uptake of kharif cowpea” during kharif season of 2020. In Randomize Block Design, eight treatment combinations were tested in four replications. Cowpea variety Gujarat cowpea 5 was planted at a distance of 45 cm × 10 cm. Application of 75% of RDF + 2% spray of each urea and urea phosphate at 15 and 30 DAS gave significantly higher yield (1422 kg/ha), protein content (22.93 %), nutrient content of nitrogen and phosphorus in seed (3.67 % and 0.446 %) and in stover (0.73% and 0.273% respectively) and nutrients uptake of nitrogen (71 kg/ha), phosphorus (13 kg/ha) and potassium (56 kg/ha) by cowpea crop it was at par with application of 75% of RDF + 2% spray of NPK 19:19:19 at 15 and 30 DAS

8 of 12 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
