Abstract

Green house experiments were conducted with greengram ev KM-2 during June 2002, to find out the effect of plant growth regulators on yield and quality of greengram under graded levels of nitrogen. The experiment was conducted in a factorial RBD with 3 replications. The treatments constituted 4 levels of N viz. 0, 25.0, 37.5, 50 kg ha and growth regulators viz. naphthalene acetic acid (NAA), mepiquatchloride (MC) and triacontanol at recommended levels compared with water spray. The results revealed that application of 50 kg N ha-1 along with NAA spray excelled other treatments in increasing the growth, yield characters and protein content of greengram, followed by MC spray at 50 kg ha-1 of N.
