Abstract
An investigation was carried out to study the effect of organic manures and inorganic sources of nitrogen on growth, grain yield and its attributes in Rabi maize of rice – maize cropping system planned with three organic manural options viz., no manuring, in-situ incorporation of green manure crop (Sesbania aculeata) and farm yard manure @ 10 t. ha-1 (M1, M2 and M3, respectively) and four levels of Nitrogen viz., 0, 50, 100 and 150% RDN (N1, N2, N3 and N4) and also three more levels of Nitrogen i.e., 50, 100 and 150% RDN (N5, N6 and N7) included among sub plot treatments to observe their residual and cumulative effect on sequence crop of Rabi maize in relation to different levels of Nitrogen i.e., 0, 50, 100 and 150% RDN imposed to maize crop. During kharif (rice) season, three organic manural options as main plot treatments and seven Nitrogen levels (N1, N2, N3, N4, N5, N6 and N7) as sub plot treatments were tested in a split plot design and replicated thrice. In the same experimental lay out, Rabi maize was sown with three organic manural treatments imposed to kharif rice as main plot treatments and seven Nitrogen levels as sub plots; and replicated thrice. The experimental data was recorded on plant growth, development; yield and yield attributes of Rabi maize crop during both the years of study. The results indicated that the organic manural options i.e., in-situ incorporation of green manure crop (Sesbania aculeata) and farm yard manure @ 10 t. ha-1 (M2 and M3, respectively) significantly influenced the plant growth of Rabi maize in terms of plant height, dry matter production etc., in comparison to no manuring treatment (M1). Similarly, the yield attributes and grain yield were also significantly enhanced due to both the organic manural options Variations in growth characters of maize due to residual effect of different N levels applied to rice crop (50, 100 and 150% RDN) were not significant and remained at par. Application of graded levels of nitrogen from 50 to 150% RDN to maize enhanced the plant height, dry matter production during both the years. The days to 50 per cent flowering and days to physiological maturity were not influenced due to residual effect of different pre-rice organic manuring options during both the years of study while, they were significantly shortened due to higher levels of nitrogen. Grain and stover yield significantly increased due to pre-rice organic manuring options and nitrogen levels over the respective control treatments in both the years. (4224 and 3905 kg ha-1 in the first year; and 4428 and 4499 kg ha-1 in the second year, respectively).
