Abstract
The field experiment was conducted at Ambagarathur village,Thirunallar Taluk, Karaikal District of Puducherry during the kharif season (June-September, 2021) for“Enhancing greengram crop architecture through intervention of foliar nutrition on growth and yield of irrigated greengram”. The experiment was laid out in Randomized Block Design (RBD) with thirteen treatments and three replications.The treatment schedule were as follows : T1- RDF + water spray (control), T2- RDF + foliar application of 2 % DAP and NAA 40ppm on 30 and 45 DAS, T3- RDF + foliar application of 1 % potassium sulphate on 30 and 45 DAS, T4- RDF + foliar application of 1 % TNAU Pulse wonder on 30 and 45 DAS, T5- RDF + foliar application of 2 % poly feed on 30 and 45 DAS, T6 - RDF + foliar application of 2 % DAP and NAA 40ppm + 3% seaweed extract on 30 and 45 DAS, T7- RDF + foliar application of 1 % potassium sulphate + 3% seaweed extract on 30 and 45 DAS, T8 - RDF + foliar application of 1 % TNAU Pulse wonder + 3% seaweed extract on 30 and 45 DAS, T9 - RDF + foliar application of 2 % poly feed + 3% seaweed extract on 30 and 45 DAS, T10 - RDF + foliar application of 2 % DAP and NAA 40ppm + 3% seaweed extract + 2 % humic acid and fulvic acid on 30 and 45 DAS,T11 - RDF + foliar application of 1 % potassium sulphate + 3 % seaweed extract + 2 % humic acid and fulvic acid on 30 and 45 DAS, T12 - RDF + foliar application of 1 % TNAU Pulse wonder + 3 % seaweed extract + 2 % humic acid and fulvic acid on 30 and 45 DAS, T13 - RDF + foliar application of 2 % poly feed + 3 % seaweed extract + 2 % humic acid and fulvic acid on 30 and 45 DASAmong the different treatments, application of RDF + foliar application of 1% TNAU Pulse wonder, 3% seaweed extract, 2% humic acid and fulvic acid on 30 and 45 DAS (T12) recorded significantly higher yield attributes such as number of pods plant-1(32.45), number of seeds pod-1(9.00), test weight(3.69), yields( seed yield 1583 kg ha-1and haulm yield 3561 kg ha-1), and harvest index (30.87). From the above results, it has been concluded that the application of RDF + foliar application of 1% TNAU Pulse wonder, 3% seaweed extract, 2% humic acid, and fulvic acid on 30 and 45 DAS (T12). The higher N (48.60 kg ha-1), P (
