Abstract

The rising demand for high-quality rice and rice products motivates farmers to produce traditional rice varieties. Rice production needs to be substantially increased with suitable nutrient management practices to meet the demand. Hence, the present study was carried out to evaluate the influence of integrated nutrient management practices on nutrient yield and quality of improved black kavuni rice. The research was conducted during the Early kar (April-August 2023) and Late samba (September - January 2023-24) seasons in a randomized block design (RBD) with three replications and twelve treatments consisting of N in equivalent basis with organic manure and inorganic fertilizers and one control. Based on an N equivalent basis, the required quantity of inorganic fertilizer, farmyard manure (FYM), vermicompost (VC) and poultry manure (PM) were applied to rice. Observations on nutrient uptake, yield and quality were recorded, and the data were analyzed using LSD at a 5% probability level for significance differences. The results revealed that higher nutrient uptake, yield and quality parameters of rice were recorded with 50% recommended dose of nitrogen through inorganic fertilizer + 50% recommended dose of nitrogen through VC + foliar spray of 0.5% ZnSO4 & 1% FeSO4 at tillering, panicle initiation (PI) and flowering stage (T11).

8 of 14 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
