Sawah Rice Farming Eco-technology Options for Enhancing Sustainable Nutrient Management and Rice Production in Degraded Inland Valleys of Southeastern Nigeria

Abstract

This work was carried out in collaboration between all authors. Author JCN designed the study, wrote the protocol and wrote the first draft of the manuscript. Author AOO managed the literature searches;analyses of the study performed the spectroscopy analysis. Author CAI managed the experimental process and author TW identified the species of plant. All authors read and approved the final manuscript.

Improving soil silicon and selected fertility status for rice production through rice-mill waste application in lowland sawah rice field of southeastern Nigeria

“…Year 2 (2015 cropping season) RHA 120 163 148 192 175 146 157 RHD 146 158 168 170 157 134 155 Mean 133 160 158 181 166 140 156 LSD (0.05) treatments = 1.45; p = 0.041 LSD (0.05) treatment rates = 2.06; p < 0.001 1 3 lowland rice field. This is because pre-farm activities such as bunding, surface field leveling, irrigation and drainage modifications in the sawah system help in preventing erosion (Nwite et al 2016b). Sawah system has been reported to have positive effect in restoring/replenishing lowland with nutrients due to geological fertilization (Wakatsuki et al 2005).…”

Effect of Different Land Preparation Methods for Sawah System Development on Soil Productivity Improvement and Rice Grain Yield in Inland Valleys of Southeastern Nigeria

“…Farmers need to know that rice field environment determines how soil fertility, weed and water control can best be managed for optimum rice production. at in order to realize and sustain the potential benefits accruable from cultivating the inland valleys of West Africa, much of the research effort in these land resources is geared towards alleviating verally as an Indo-(Malay word for paddy) or lowland rice management system comprising bunding, puddling, levelling and good water management through irrigation and drainage system through its control/ maintenance ield surface water level during plant growth period, contribute to the alleviation of global warming problems through the fixation of carbon soils in ecologically It restores/replenishes the lowland with nutrients through geological fertilization as it resists sawah system of nutrient replenishments in lowlands through geological fertilization encourage not only rice growth, but also the breeding of various microbes, which improves biologi fixation [16].…”
