Abstract

Objectives: The effects of different levels of organic fertilizers on the growth and yield of rice were investigated in a coastal field ecosystem under the systems of rice intensification (SRI) technology. Methods/Statistical Analysis: The study was conducted in a coastal rice field with 8.38 pH. It was laid out in a split-plot design with four treatments replicated thrice. Different amounts of organic fertilizer were applied as basal fertilizer. Data were statistically analyzed using analysis of variance (ANOVA). The significance of the treatment effect was determined using the F-test. Least significant difference (LSD) determined which means are statistically different at the 5% probability level. Findings: Results showed that the filled grains and yield increase were 35.6% and 45%, respectively, when applied with an organic fertilizer at the rate of 6 ton/ha compared with the control. Other parameters measured like the height of plants at maturity and the number of unfilled grains were all comparable with the control group. Applications: SRI technology is a potential option for growing inbred rice in coastal rice fields. Keywords: Coastal rice field; Organic-based; Rice crop; System of rice intensification

Highlights

Intensifying agricultural outputs to fulfill the continuously growing demands on food is the focus of a conventional system of producing foods supported by the advancement of science and technology
With a spacing of 25 cm x 25 cm on a square grid, and organic fertilizer was applied to the soil
It appears that the performance of inbred rice in systems of rice intensification (SRI) varied with the amount of organic fertilizer applied

Summary

Introduction

Intensifying agricultural outputs to fulfill the continuously growing demands on food is the focus of a conventional system of producing foods supported by the advancement of science and technology. With the advent of new technologies, the traditional method has multiplied the yielding of crops. It has adverse consequences on human health and the environment[1]. The purpose of the technology is to find sustainable agricultural practices that lead to higher productivity, optimum use of capital and labor, less input cost, and less requirement of water. According to[3], SRI is a way of matching the elements of soil, water, light, and crop to allow crops to receive their fullest potential that is often hidden when inappropriate techniques are used
