Abstract

The field experiment was conducted during rabi 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (UP). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 6.8), low in the organic carbon (0.49 %), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out in Randomized Block Design with nine treatments including control each replicated thrice on the basis of one year experimentation. The treatments consist of T1: Nano zinc 40 ppm + Chloromequat chloride 0.25 mg/l, T2: Nano zinc 40 ppm + Salicylic acid 400 mg/l, T3: Nano zinc 40 ppm + Benzyl amino purine 200 mg/l, T4: Nano zinc 80 ppm + Chloromequat chloride 0.25 mg/l, T5: Nano zinc 80 ppm + Salicylic acid 400 mg/l, T6: Nano zinc 80 ppm + Benzyl amino purine 200 mg/l, T7: Nano zinc 120 ppm + Chloromequat chloride 0.25 mg/l, T8: Nano zinc 12 ppm + Salicylic acid 400 mg/l, T9: Nano zinc 120 ppm + Benzyl amino purine 200 mg/l and T10: Control are used. The results obtained that growth parameters viz., plant height (83.50 cm), Number of tillers per plant (12.67) and dry weight (35.12 g/plant) were recorded higher with the application of Nano zinc 120 ppm + Salicylic acid 400 mg/l. Significantly maximum yield parameters viz., number of grains per spike (28.00), number of effective tillers/hill (9.47), and test weight (42.39 g) were recorded superior with the application of Nano zinc 120 ppm + Salicylic acid 400 mg/l.

8 of 9 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.
