Description |
A . pot cul~ure experiment was conducted for kharif season on black cotton soil, brought from A·R·S· Lam, Guntur to stud~ · the effect of graded levels of nitrog~n with and without inoculation for increasing productivity of soybean. The different treatmen~s of nitrogen .(0, 20,40,60 and 80 kg .. - haf " > with and without inoculat ior. wer·e tested in ra~domised block design with three replications a on simp 1 e . Har·dee variety. Effect of treatments on the NR activity, Protein content, oil content, nodule number and nodule weight, dry matter and yield were studied. Native bacteria of the soil has greatly influenced in producing more number of nodules and nodule weight at all the stages of plant growth. The contribution of native bacteria in increasing the dry matte~ was great and led to the incrased yields in terms of grain• The enzyme activity of ni tr·ate r·ed1..tctase was significantly influence wi th uninoculation at all the stages of growth. The similar trend was observed in protein content of grain but oil content of seed was sign~ficantly decreased· Increasing levels of nitrogen from 0 to 60 kg ha-1 increased the nodule number and nodule weight at all the stages of . plant growth and at eo·kg ha-1 reduced both nodule number and weight· 60 kg ha-1 has produced more of dry matter per plant at all the stages of growth but 80 kg ha-1 had nonsignificant increase over 60 kg ha- 1 • Application of nit~ogen from 0 to 60 kg ha-1 had increased significantly the grain yield· Increasing levels of nitrogen upto 60 kg ha-1 has induced the activity of the enzyme nitrate reductase and inhibited at 80 kg ha-1 at all the stages of plant growth· Protein content of grain increased significantly upto 60 kg and the SO kg ha- 1 showed a non significant influence. The oil content of the seed decreased significantly with increasing the nitrogen application upto .eo kg ha- 1 • Thus from the view of ecnomy, application of nitrogen at 60 kg ha-1 level with no inoculation in continuo~~ly cropped area with pulses was th9 best b~lanced fertilization for increasing productivity of soybean. |
