Abstract
To find out the organic nitrogen management in agricultural field using neem cake vermicompost and NADEP compost as organic sources in wheat crop. The experiment was carried out in split plot design randomized with three replications. Four organic nitrogen management practices viz., Control (No manure), 50% RDN (1/3 Neem cake + 1/3 Vermicompost + 1/3 NADEP compost), 75% RDN (1/3 Neem cake + 1/3 Vermicompost + 1/ 3 NADEP compost) and 100% RDN (1/3 Neem cake + 1/3 Vermicompost + 1/3 NADEP compost) in main plot and seven weed management practices viz., Control, hand weeding at 25 & 50 DAS, hoeing at 25 & 50 DAS, intercropping with mustard (4:2), straw mulch fb hand weeding at 30 DAS, straw mulch fb hoeing at 30 DAS and green manuring at 25 DAS were applied for the experiment in sub plot. Application of 100% RDN (1/3 Neem cake + 1/3 Vermicompost + 1/3 NADEP compost) recorded significantly higher protein content, protein yield and nitrogen status of grain and straw of wheat over rest of the treatments. Among different weed management practices in wheat crop failed to bring about significant variation on protein content in grain and nitrogen status of grain and straw during both years as well as in pooled analysis.
