Effects of Integrated Nutrient Management and Moisture Regime on Hybrid Rice, Oryza Sativa L.

Abstract

Hybrid rice, Oryza sativa L., has been extensively investigated because of the consequences of integrated nutrition management and moisture regime on rice production. In order to maximize nutrient availability and utilization by the crop, integrated nutrient management involves integrating several types of nutrients, such as organic manures, chemical fertilizers, and biofertilizers. On the other hand, the term "moisture regime" is used to describe the methods used to regulate the flow of water to the rice field. Silt loam soil was used for the experiment, and its pH ranged from 8.2 to 8.4, its organic carbon content was 0.30 to 0.31 percent, and its available nitrogen (N), phosphorus (P), and potassium (K) contents were around 185.00 to 189.0, 16.0 to 16.2, and 282.00 to 284.00 kg ha-1. The rice variety Arize-6444 was planted with a fertilizer solution of 150 N:75 P2O5:60 K2O kg ha-1. Twenty kilograms per hectare were planted with seeds. 7 cm irrigation at 1 DADPW significantly increased plant height, dry matter accumulation, leaf area index, shoot number per running meter, yield, and yield characteristics compared to 7 cm irrigation at 4 and 7 cm DADPW and conventional irrigation.
