Effect of Zinc and Salicylic Acid on Growth and Yield of Green Gram (Vigna radiata L.)

Abstract

A field experiment was carried out through the growth season 2022 at Zaid Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). To Study the effect of Zinc and Salicylic acid on improve growth green gram (Vigna radiata L) in sandy loam. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36 %), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out on Randomized Block Design with nine treatments each replicated thrice on the basis of one year experimentation. The treatments which are T1: Zn (75PPM) + Salicylic acid (100PPM), T2: Zn (75PPM) + Salicylic acid (150PPM), T3: Zn (75PPM) + Salicylic acid (200PPM), T4: Zn (100PPM) + Salicylic acid (100PPM), T5: Zn (100PPM) + Salicylic acid (150PPM), T6: Zn (100PPM) + Salicylic acid (200PPM), T7: Zn (125PPM) + Salicylic acid (100PPM), T8: Zn (125PPM) + Salicylic acid (150PPM), T9: Zn (125PPM) + Salicylic acid (200PPM) are used. The results showed that treatment T9- Zn (125PPM) + Salicylic acid (200PPM). Result was recorded significantly higher growth parameters i.e. Plant height (35.14 cm), Plant dry weight (6.64 g/plant) and Crop growth rate (2.99 g/m2/day). However, yield attributes and yield parameters like No. of Pods/plant (21.22), No. of seeds/pod (11.35), Test weight (34.04 g), Seed yield (1100.97 kg/ha), straw yield (4471.00 kg/ha) were affected with the treatment T9- Zn (125PPM) + Salicylic acid (200PPM) than other treatments. Higher gross returns (Rs. 82572.75/ha), net return (Rs. 56228.32/ha) and benefit cost ratio (2.13) was obtained in the treatment T9- Zn (125PPM) + Salicylic acid (200PPM) as compared to other treatments.
