Abstract
The field trail titled “Effect of Nitrogen and Zinc on growth and yield of Cowpea” was conducted during Zaid, 2022 at Crop Research Farm, Department of Agronomy, Naini Agriculture institute, SHUATS, Prayagraj, Uttar Pradesh. The soil of experimental field was sandy loamy in texture, nearly neutral in a soil reaction (pH 7.8) low in organic carbon (0.62), available nitogen (225 kg/ha), available phosphorus (38.2 kg/ha) and available potassium (240.7 kg/ha). The experiment was carried out in Randomized Block Design with nine treatments each replicated thrice. The treatments combination are T1: N-20 kg/ha + Zn-10 kg/ha, T2: N-20 kg/ha + Zn-20 kg/ha, T3: N-20 kg/ha + Zn-30 kg/ha, T4: N-30 kg/ha + Zn-10 kg/ha, T5: N-30 kg/ha + Zn-20 kg/ha, T6: N-30 kg/ha + Zn-30 kg/ha, T7: N-40 kg/ha + Zn- 10 kg/ha, T8: N-40 kg/ha + Zn-20 kg/ha and T9: N-40 kg/ha + Zn-30 kg/ha. Results revealed thatcombined application of Nitrogen 30 kg/ha along with Zinc 30 kg/ha significantly Higher plant height (51.39 cm), number of branches/plant (4.80), dry weight (16.60 g), number of pods/plant (10.60), number of Seeds/pod (5.47), seed index (100.80 g), seed yield (1.30t/ha), stover yield (1.73 t/ha). And also higher economics viz., higher gross returns (1,01,380.00 INR/ha), net returns (67,812.00 INR/ha) and B:C ratio (2.02).
