Fertilizer bio urine effectiveness test and the combination with chemical fertilizer on nutrient uptake and rice production

Abstract

The goal of the study was to determine the impact of applying bio urine fertilizers on soil chemical properties and rice yield in order to improve soil fertility. Randomized complete block design with 10 kinds of treatment had adopted in this study for three times. As part of the treatment, bio urine fertilizer and NPK fertilizer are used at various levels. As a result of these findings, the use of bio urine in conjunction with NPK fertilizer had a significant impact on pH as well as total N as well as available P and K as well as absorption of N, P and K, strawweight, dry grain weight and 1000 grain weight. As a result, rice plants can absorb more nutrients such as organic C, total nitrogen, existing P, K, N, P and K when combined with NPK fertilizer. 5.65 t ha-1 of rice was harvested using 30 ml of bio urine and 75 percent NPK fertilizer, while 4.01 t ha-1 of rice was harvested using the farmer's (control) method of treatment. It's 165.66 percent. When used at this dosage, the fertilizer is more in effect than standard fertilizers, and its economic test magnitude is about 1.42, making it a good choice for rice farming.
