Abstract

Field experiment conducted at Hebbal, Bangalore, on TMV-2 groundnut during 1976 and 1977 summer seasons, to study the effect of moisture stress and hormonal influence indicated that the total flowers produced in plants stressed between 30 10 45 days from sowing did not differ significantly from the regularly irrigated plots. The pod yield in stressed plots reduced by 4.7 per cent compared to normally irrigated crop with a yield of 3533.5 kg/ha. The flower primordial initiation and the first flower opening were noticed 14 and 24 days after sowing respectively. The first flush of flowers produced before 45th day from sowing dried up and did not form gynophores in stressed plants. However, a higher percentage of fruit set from the second flush compensated for yield differences in both seasons. NAA spray of 25 ppm at any stage of growth did not influence the total flower production as well as yield significantly in stressed and regularly irrigated plots.
