EFFECTS OF NPK FERTILIZER AND FARMYARD MANURE RATES ON MILLET PERFORMANCE IN SUDAN AND SAHEL SAVANNA SOILS OF NORTHEAST NIGERIA Effect t of NPK and FYM manure on millet growth

Effects of Ridge Tillage and Organic Manure Treatment on Growth, Leaf Nutrient Concentration and Pearl Millet (Pennisetum glaucum) Stover Yield in Semi-arid Northeast Nigeria

“…Combining land preparation practice of ridge tillage with organic solid waste management such as wood shavings (Chiroma et al, 2004a;Chiroma et al, 2006abc) had been shown to improve soil properties and crop yields in the savanna northeast Nigeria. Whereas the fertilizer value of farm yard manure had been demonstrated in previous studies conducted in this area (Chiroma et al, 2004b;Ngala et al, 2020), no study has evaluated its value in association with the land configuration practice of ridge tillage. The enhanced nutrient supply through solid wastes decomposition coupled with favorable moisture condition creates conducive environment for plant growth and development (Dass et al, 2013).…”

“…The enhanced nutrient supply through solid wastes decomposition coupled with favorable moisture condition creates conducive environment for plant growth and development (Dass et al, 2013). Several studies reported that soil organic carbon content, as an indicator of soil fertility, is increased through conservation tillage systems that incorporate organic solid wastes into the soil (Singh et al, 2003;Busari et al, 2015;Ngala et al, 2020). According to Busari et al (2015), maintaining at least 30% year-round soil surface residue cover, offers the potential to sequester carbon, enhance soil organic matter, and reduce erosion.…”
