EFFECT OF ORGANIC MANURE ON SORGHUM PRODUCTIVITY GROWN IN RESIDUAL MOISTURE IN BAKURA, NIGERIA

Abstract

Agriculture is mainly under rain-fed conditions in Zamfara State as the rainfall is very uncertain and temperature is increasingly high which is a major challenge and detrimental to crop growth and development. Therefore, climate risk management in agriculture (rainfed and residual moisture) is among the most important pillars of food security and resilience of agro-ecosystems. The objective of this study was to address residual farming system in Bakura area of Zamfara State. The experimental design was a dispersed randomized complete block design with 4 to 6 replications where each farmer was considered as a replication. The findings revealed that the treatment F7 (18 kg ha^-1 of NPK + 500 kg ha^-1 of organic manure gave the highest mean grain yield in 2012, 2013 and 2014; and the treatment F0 (0 kg ha^-1) gave the lowest mean grain yield.
