dc.description.abstractIn order to study the effect of various nitrogen sources on growth, yield and yield attributes and soil properties, a field experiment was conducted during Kharif 2020 at farm of Krishi Vigyan Kendra, Fatehabad (Haryana). The experiment was planned in a randomized block design with fourteen treatments replicated thrice Based on the research investigation, it was observed that different nitrogen sources significantly affected the growth, yield, yield attributes, economics and soil properties under rice cultivation. Among different sources, treatment with 100% RDN through urea recorded significantly higher plant height (95.42 cm), number of tillers (372.17 m-2), grain yield (44.61 q ha-1) and straw yield (96.88 q ha-1). Highest gross net return (Rs. 87355 ha-1), net return (Rs. 50635 ha-1) and benefit cost ratio (2.38) was observed in treatment 100% RDN through urea. Decrease in soil pH, EC and increase in soil organic carbon was observed in treatments where nitrogen was applied through organic manures viz. FYM, vermicompost and poultry manure as compared to initial value. The highest available N (120.30 kg ha-1), P (19.13 kg ha-1), K (237.20 kg ha-1) and S (34.50 kg ha-1) was observed in treatment where RDN was applied through poultry manure. The content of micronutrients increased with application of FYM, vermicompost or poultry manure alone or in combination with chemical fertilizer and found highest in treatment receiving 100% RDN through vermicompost. Highest nitrogen, phosphorus, potassium and sulphur content and its uptake in rice was observed where 100% RDN applied through chemical fertilizer.en_US
