Influence of growth regulators on growth, phenological traits and yield attributes of wheat [Triticum aestivum L.] under restricted irrigation condition

Abstract

Water limiting condition creates imbalance or deficiency of growth regulators in plant, which leads toward reduce crop yield. The present investigation entitled “Influence of growth regulators on growth, phenological traits and yield attributes of wheat [Triticum aestivum L.] under restricted irrigation condition” was conducted during the Rabi season during 2017-18 and 2018-19 at Students’ Instructional Farm, Nawabganj, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur-208002 (U.P.), India in randomized block design with three replications and exogenous application of growth regulators with control wheat plants viz., Control, GA3 20 ppm, GA3 40 ppm, Alar 100 ppm, Alar 200 ppm, ABA 25 ppm, ABA 50 ppm, SA 50 ppm, SA 100 ppm, Kinetin 5 ppm and Kinetin 10 ppm on wheat variety (K1317) under restricted irrigation condition. Crop growth and yield attributes were assess during the experimentation. Study revealed that crop reduced growth and yield in term of plant height at maturity stage, number of leaves plant-1 at all observation stage, days to anthesis, days to maturity, main spike length and grains weight plant-1 under restricted irrigation, while, these parameters were improved with application of growth regulators. Maximum crop growth and yield traits were recorded with application of growth regulators GA3 40 ppm as compare to other treatments.
