Influence of Plant Growth Regulator (TA-41) on Growth and Yield of Wheat (Triticum aestivum L.)

A field experiment was carried out during rabi season of 2021, at crop research farm of Department of Agronomy at Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) India. The experiment was entitled as “Influence of plant growth regulator (TA-41) on growth and yield of wheat (Triticum aestivum L.)”. The experiment was laid out in randomized block design (RBD) which consisted of seven treatments and replicated thrice viz., T1: Control (No application), T2: TA-41 at 5.0 liter in 200 liter of water in 1 hectare, T3: TA-41 at 7.5 liter in 200 liter of water in 1 hectare, T4: TA-41 at 10.0 liter in 200 liter of water in 1 hectare, T5: TA-41 at 200 ml in 15 liters of water [full tank], T6: TA-41 at 300 ml in 15 liters of water [full tank] and T7: TA-41 at 400 ml in 15 liters of water [full tank]. he result of experiment showed that growth parameters viz., plant height (90.77 cm) significantly higher in treatment T2 with application of TA-41 at 5.0 liter in 200 liter of water in 1 hectare and dry weight (17.73 g), number of spikes/m2 (442.67), grains/spike (55.56), grain yield (6.88 t/ha) and straw yield (15.7 t/ha) were recorded significantly maximum in treatment T7 with application with TA-41 at 400 ml in 15 liters of water [full tank]. Maximum gross returns (1,85,732.00 INR/ha), net returns (1,32,637.47 INR/ha) and benefit: cost ratio (2.5) were also obtained highest in treatment T7 with application with TA-41 at 400 ml in 15 liters of water [full tank].
