This study investigates the influence of soil composition, soil type, and agricultural
techniques on rice (Oryza sativa) productivity and quality in Naic, Cavite. Through
detailed soil analyses of three distinct sampling sites, key physicochemical properties such
as pH, total nitrogen, available phosphorus, exchangeable potassium, electric conductivity,
organic matter, and moisture content were assessed. The research aimed to correlate these
properties with rice growth parameters and yields while evaluating the effectiveness of
various agricultural practices. Results showed significant differences in soil properties
impacting rice productivity. Sampling Site 1, characterized by balanced soil properties and
optimized farming techniques, achieved the highest yield of 94.44 kg/ha. Sampling Site 2,
despite sandy loam soil’s nutrient retention challenges, produced high-quality grains with
the longest average grain length of 0.73 mm due to effective nutrient management.
Sampling Site 3, despite applying fertilizers at a rate of 131.58 kg/ha, had the lowest yield
of 71.58 kg/ha, suggesting that the higher fertilizer application was insufficient to
overcome the inherent soil and water management challenges. The study emphasizes the
critical role of tailored agricultural practices, particularly in irrigation and fertilization, to
maximize rice yields and quality.
