Response of Groundnut Crop to Stand Geometry in Rice Fallows in Coastal Sandy Soils of Uttara Kannada District in Karnataka

C.A. Agasimani, M.M. Hosmani

Abstract


Experiments were conducted on the sandy loam soils of west coast of Uttara Kannada district in rice fallows under receding soil moisture conditions during rabilsummer seasons of 1983-84, 1984-85 and 1985-86. These experiments were laidout at three locations namely Amadalli, Ankola and Holanagadde to find out the optimum stand geometry for Cv. Dh-3-30. During 1983-84 at Ankola significant differences were observed for pod yield. Highest pod yield of 3427 kg per ha was obtained in local method of sowing behind the plough with spa­cing of 20cm x 10-15 cm. During 1984-85 at Ankola significantly higher pod yield of 3687 kg per ha was recorded at the stand geometry of 20cm x 5 cm over rest of the stand geome­tries except 20 cm x 10 cm. The pod yield data of mean over locations and years indicate that the pod yields differed significantly due to various stand geometries The stand geome­try of 20 cm x 5 cm recorded significantly higher pod yield (3238 kg/ha) than other treat­ments except 20 cm x 10 cm. (2706 kg/ha). There was no significant differences among other stand geometries.
