Behaviour of growth of groundnut under different environments and row spacing

A field experiment to study the effect of sowing time and row spacing on behaviour of growth of groundnut crop in Southern Telangana Zone was conducted during kharif 2006 at College Farm, College of Agriculture, Rajendranagar, Hyderabad. The results revealed that LAI, CGR and dry matter production were significantly more in early sown crop at 30, 60 DAS and at harvest. The crop sown at inter-row spacing of 30 cm recorded significantly more LAI, CGR and dry matter accumulation at 60, 90 DAS and at harvest. Correlation studies between dry matter partitioning at 30, 60 and 90 days after sowing and at harvest and pod and haulm yield revealed that dry matter partitioned into stem at 60, 90 DAS and at harvest had significant positive correlation with final pod and haulm yields, the dry matter partitioned into leaves showed significant positive correlation with both pod and haulm yield at 60 DAS and later with haulm yield only at 90 DAS and at harvest. The dry matter partitioned into pods at 90 DAS and at harvest had significant and positive correlation to final pod and haulm yields. The total dry matter produced during sampling dates at 60, 90 DAS and at harvest showed significant positive correlation with final pod and haulm yields. However, the dry matter production and partitioning at 30 DAS did not show significant relation with pod and haulm yields. The results highlighted that groundnut should be sown latest by end of July and spacing of 30 cm be adopted for better crop growth.
