Effect of nitrogen scheduling on yield, nutrient content and uptake in boro rice lowland rice ecosystem

Author(s): Pooja, Sandeep Kumar, Khushboo Gupta, Sudhanshu Verma and UP Singh
Abstract: A field experiment on boro rice was conducted at Agricultural Research Farm, Banaras Hindu University, Varanasi, Uttar Pradesh, 2014-15 to evaluate the effect of different N levels on yield attributes, yield, nutrient content and uptake by rice variety IR-8. Experiment was laid out in randomized complete block design involving different N levels (0, 90, 120 and 150Kgha-1) at different stages (Active tillering, Panicle initiation, Flowering and Heading) replicated three times. Results revealed that increasing N levels up to 150kg (¼ at Basal + ¼ at AT + ¼ at PI+ ¼ at H) significantly improved yield attributes, grain yield and straw yield as well as nutrient content and uptake by grain and straw. However, application of N 120 Kg Nha-1 (¼ at Basal+ ¼ at AT+ ¼ at PI + ¼ at H) produced comparable results regarding yield attributes and yield. Hence, the study suggests that higher fertilizer dose when applied in splitting at different doses give better performance of the boro rice crop.
