摘要

A field experiment was conducted during the kharif 1997 and 1998 at the Crop Research Centre, Pantnagar, to study the effect of copper application on nodule leghemoglobin content, grain yield and quality of soybean (Glycine max L.). Sixteen treatment combinations consisting of four varieties (Bragg, PK 262, PK 416 and PK 1042) and four copper levels (0, 2.5, 5 and to kg Cu ha~(-1)) were tested in split plot design with three replications. Soybean varieties differed significantly in their copper requirement in terms of nodule leghemoglobin content, grain yield, protein and oil content. The variety, PK 416 showed an increased trend of these characters and can be grown in soils containing high available copper, while Bragg was sensitive. Copper @ 2.5 kg ha~(-1) significantly increased the leghemoglobin content in nodules both at 45 and 60 days. Application of copper did not increase the grain yield significantly in both years but interactions between varieties and copper levels for grain yield weresignificant. The variety, PK 416 consistently out yielded other varieties and gave the highest grain yield at 5 kg Cu ha~(-1) (1785 kg ha~(-1)) and Bragg yielded the lowest. Application of 2.5 and 5 kg Cu ha~(-1) significantly increased grain protein and oil content during 1997 and 1998 resulting in 4.30 and 9.69, 1.92 and 4.82 percent increase over control.
