Abstract:
The field experiment was conducted during Kharif 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). 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 treatment consisted of three sources of boron (soil application of 1kg/ha, foliar application 25ppm and soil application 0.5kg/ha + foliar application 15ppm) and the three levels of plant growth regulator (GA1 50ppm, GA2 100ppm and GA3 150ppm) and one control plot respectively. The experiment was laid out in Randomized Block Design with Ten treatments each replicated thrice on the basis of one year experimentation. The treatments which are T1:Control, T2: Soil application Boron 1kg/ha + GA3 50ppm, T3: Soil application Boron 1kg/ha + GA3 100ppm, T4: Soil application Boron 1kg/ha + GA3 150ppm, T5: Foliar application Boron 25ppm + GA3 50ppm, T6: Foliar application Boron 25ppm + GA3 100ppm, T7: Foliar application Boron 25ppm + GA3 150ppm, T8: Soil application 0.5kg/ha + Foliar (15ppm) + GA3 50ppm, T9: Soil application 0.5kg/ha + Foliar (15ppm) + GA3 100ppm, T10: Soil application 0.5kg/ha + Foliar (15ppm) + GA3 150ppm are used. The results showed that application of Soil application 0.5kg/ha + Foliar (15ppm) + GA3 150ppm was recorded significantly higher plant height (185.99 cm), Plant dry weight (187.82 g/plant), Crop growth rate (7.18 g/m2/day), Cobs/plant (1.34), Seeds/row (29.36), Row/cob (14.73), Seed yield (7.70 t/ha), Stover yield (12.28 t/ha), Test weight (215.73 g), Harvest index (38.55%), gross returns (Rs. 1,23,200/ha), net return (Rs. 82,416.31/ha) and benefit cost ratio (2.02) as compared to other treatments.
