Response of lowland rice varieties to integrated nutrient management in a derived Savannah agro-ecology

Abstract

In the inland valley (FADAMA) of the Directorate of University Farms (DUFARMS) of the Federal University of Agriculture, Abeokuta (FUNAAB) in Nigeria, an experiment was conducted successfully. The objective was to see how integrated nutrient sources influenced the performance of two lowland varieties of rice. A split-plot two-factorial experiment was used in the study, and it was replicated three times in a randomized complete block design. Rice seedlings were transplanted 12 days after being planted in the nursery to a depth of 3 cm and a spacing of 20 cm × 20 cm, one seedling per hill. Two varieties and six nutrient sources were used for the research. Rice yield and growth data were collected. ANOVA (Analysis of Variance) was used on data, and the significant means were separated using Tukey HSD (Honestly Significant Difference) at a probability level of 5%. ARICA 3 grew taller than NERICA L-34 as a result of the research. ARICA (Advanced Rice Varieties for Africa) 3 exceeded NERICA (The New Rice for Africa) L-34 in terms of shoot dry weight (4 WAP (Weeks After Planting) (1.53) and 6 WAP (1.53 g), respectively (5.60 g). Rice cultivars produced the highest grain when 25 kg N ha-1 (NPK 20:10:10) and 75 kg N/ha (Poultry manure) were applied.
