A Study of the Effects of Site, Variety, and Fertilizer Application on Rice Agronomic Traits Using Least Squares Mean Plots (LSMP)

Abstract

This study aimed to examine the effects of site, variety, and fertilizer application on rice growth and that of their interaction that produce the highest average response of plant height, tiller height, and grain yield of rice production using Least Square Means Plot. The experiment was conducted across multiple sites with different soil types and environmental conditions. Four distinct crop varieties were selected and three different fertilizer treatment were applied. Data on various agronomic traits, including plant height, tiller height, and yield were collected to assess the interactions between the factors. Results among the three variables revealed that plant height has the highest mean value indicating robust vegetative growth, site1 demonstrated the most favorable conditions overall with the tallest plant. The result among the four tasted rice varieties faro49, faro55, faro57 and Nerica7 in terms of plant height, tiller height, and yield, Faro49 emerged as the most vigorous and productive variety, exhibiting the tallest plants. The results among the three different responses plant height, tiller height, and grain yield under three fertilizer treatments; control, inorganic fertilizer and poultry manure, the control group exhibits the highest average. The study highlights the critical influence of site and variety on rice growth and yield with site – specific environmental rice conditions proving to be the most significant factor in determining overall performance. Emphasize the need for integrated decisionmaking in rice cultivation, where agronomic practices should align with both environmental conditions and genetic characteristics for improved productivity.
