Influence of Planting Geometry and Nitrogen Levels on Nutrient Content, Uptake and Soil Fertility Status in Scented Rice (Oryza sativa L.)

2022 Indian Journal of Ecology  
An experiment was carried out during 2018 at Research Farm, College of Agriculture, Kaul (Kaithal) to study the influence of kharif planting geometry and nitrogen levels on nutrient (N, P and K) content, uptake and soil fertility status under scented rice (Pusa 1121). The experiment was conducted using split plot design with four replications having three planting geometry in main plots and five nitrogen levels in sub plots. N, P and K concentrations in grain and straw were Grain and straw

However, these concentration increases significantly with increase in nitrogen level and maximum at 120 kg N/ha. N, P and K uptake by both grain and straw were significant at planting geometry 20 cm x 15 cm and nitrogen rate of 120 kg/ha. The available N, P O and K O of experimental field before cultivation were 163, 27 and 379 kg/ha, respectively. N, P O and K O content in soil after 2 5 2 2 5 2cultivation was higher under 30 cm x 20 cm. However, N content in soil after cultivation was maximum at 120 kg N/ha, but P O and K O content 2 5 2was in control.
