Influence of planting techniques and plant population on biology and pod productivity of summer groundnut varieties.

摘要

Two groundnut cultivars SG 84 and M 522 were evaluated under three planting techniques and three plant population in summer at Punjab Agricultural University, Ludhiana, India. The levels of plant population constituted a most vital factor influencing the pod productivity of groundnut planted in summer. A plant population of 222 000 plants/ha recorded the highest yield irrespective of cultivar compared with the reduced levels of 167 000 (25% less) and 111 000/ha (50% less). SG 84 gave relatively higher pod yield than M 522, however difference was insignificant. Different planting techniques (flat, raised bed and ridges) under the prevailing soil and climatic conditions failed to influence the pod production of groundnut.
