Abstract
An experiment was conducted during summer season of 1993 and 1994 to study the effects of sowing date, irrigation and spacing on nodulation, dry-matte r production and yield of summer groundnut (Arachis hypogaea L.), at Kalyan i. Sowing on 15 February recorded significantly highest number of nodules/p lant, dry weight of nodules and dry weight of pods/plant and pod yield than that on 15 January. Irrigation had no significant effect on nodulation. Tw o irrigations given at first phase of flowering and pod initiation recorded higher shoot and pod dry weight/plant than 1 irrigation. Three irrigations resulted in highest pod yield (2, 420 kg/ha) and moisture stress at pod-de velopment stage and both at pod initiation and development stages reduced p od yield by 13.4 and 44.2 % respectively. The crop sown at 25 cm x 12 cm sp acing recorded the highest nodules/plant, shoot dry weight and pod yield.
