MAXIMIZING YIELD AND NET RETURNS TO NITROGEN, PHOSPHORUS AND POTASSIUM FERTILIZER APPLICATION IN RICE (Oryza sativa. L) PRODUCTION ON LOWLAND SOILS

by

ABSTRACT   Rice (Oryza sativa .L) is an important staple and source of income for farmers in Nigeria. Current fertilizer recommendations for rice do not commonly consider fertilizer cost relative to paddy price (CP). The rates needed for maximizing yield rather than profits have been rather estimated. As the cost of fertilizer increases relative to … Read more

KINETICS OF SULPHATE DESORPTION IN SELECTED SOILS AS INFLUENCED BY PARENT MATERIALS AND BIOCHAR IN BAUCHI NORTH, SUDAN SAVANNA, NIGERIA

by

ABSTRACT   The absorptive nature of S by plants depends on desorption of S from soils. Understanding the kinetics desorption of sulphate as influenced by parent materials and biochar is critical for effective precision of S diagnosis and fertilization recommendations to ensure sustainable and profitable crop production and environmental protection. In this study, soils derived … Read more
