Harvest maturity of groundnut variety MKT1 for seed production

A. S. Halimathul Saadiah

Abstract

Studies were carried out to determine the optimum stage to harvest groundnut MKT1 for seed. Pods were harvested at 10-day intervals, beginning from 90 to 130 days after sowing. Statistical analysis showed harvest from the 90th day gave the highest number of immature pods and weight of immature seed than later harvests. However, there was no significant difference in number of mature pods and weight of mature seed at all harvest dates. Harvesting on the 90th day gave highest seed moisture content, lowest 100-seed weight and lowest seedling weights. Seed from harvests of the 90th, 100th and 110th day had germination above 80%. Seed (in pod) yields from harvests on the 90th to 110th day did not differ significantly; however yield was lower from later harvests. Thus, harvesting for seed should be done at 100–110 days after planting.
