Abstract

The characters of groundnut like yield of pods, size of kernels and shelling out-turn are greatly influenced by the spacings adopted. The effect of various spacings on the irrigated groundnut are discussed in this paper. John et al (1955) have reported that the yield of pods, size of kernels and shelling percentage are influenced by the seasonal conditions and other environmental factors. Nagi and Dalal (1957) have observed that in the spacing and manurial trials in Punjab, a spacing of 12"x9" registered 5.24% higher yield over the commonly adopted spacing of 12"X24". In the spacing trials conducted at the State Agricultural Farm, Bhuvaneshwar a spacing of 24"x9" was found to be the best for spreading groundnut (Anon, 1962). In the trials conducted at the Agricultural Research Station, Annigiri, Mysore State with three spacings and three seed rates viz, 12", 15" and 18" and 80 lb, 100 lb and 120 lb seed rate / acre, the spacing of 12" with a seed rate of 80 lb acre is reported to have recorded 4.2% higher yield over the general mean. (Anon, 1962b). In the spacing trials conducted on the spreading groundnut at the Botanical sub-station, Purnea, Bihar, the results revealed that a spacing of 6"X12" recorded the maximum yield of 6.4% over the general mean. (Anon, 1962c). In the spacing trials conducted at the Agricultural Research Station, Tindivanam during 1953-1955 on summer irrigated groundnut, a spacing of 9"x9" was found to be optimum for spreading groundnut (Anon. 1953, 1954 and 1955). In order to find out the influence of spacing on the various economic characters of irrigated spreading groundnut, trials were conducted at the Regional Research Station, Tindivanam, during three consecutive seasons from 1962 to 1964. During 1962 and 1964 seasons, enough irrigations could not be given due to inadequate water position in the wells. The results of the trial are presented in this paper.
