- Abstract
A field experiment was conducted during kharif 2019 on Alfisols (Kandicpaleustalfs) of farmers field at Byrasandra situated in the Eastern dry zone (Zone 5) of Karnataka to study the effect of integrated nitrogen management on growth, yield and soil properties of maize (Zea mays L.). The experiment was laid out in RCBD, comprising ten treatments replicated thrice. The results revealed that significantly higher plant height (207.13 cm) and number of leaves (15.53) cob length (19.53 cm), number of rows cob-1 (17.93), number of kernels row-1 (32.87) and test weight (31.53 gm) at harvest were recorded in the treatment which received 75 per cent of RDN + 50 per cent RD FYM + 25 per cent RDN equivalent vermicompost. Similarly, significantly higher kernel yield (79.62 q ha-1) and stover yield (89.07 q ha-1) of maize were recorded in treatment which received 75 per cent of RDN + 50 per cent FYM + 25 per cent RDN equivalent vermicompost was compared to inorganic fertilized treatment (T2) and absolute control (T1). Further, the soil test values of available N, P2O5, K2O (255.82, 51.19 and 169.87 kg ha-1, respectively) after the harvest of maize were significantly higher in the plot treated with 100 per cent RDN through (inorganic 75 per cent of RDN + organic 25 per cent RDN equivalent vermicompost or USWC sources with only 50 per cent RD FYM compared to the application of a recommended dose of fertilizer (RDF) through inorganic source and absolute control (T1). The integrated use of nitrogen along with organic manures could be the main reason for improving growth, yield and soil properties of maize crop grown in Alfisols.
