Knowledge of optimum rates of poultry manure application is of immense significance in the correction of the soil nutrient deficiencies for crop production. Manure application is of importance to both the soil amendment and in the growth and yield of crops. Leaching, pattern of cropping, use of non-certified seeds and non-improved varieties have hampered the efficient growth and yield of okra. The study was conducted to examine the growth and yield responses of okra (Abelmoschus esculentus (L.) Moench) to poultry manure rates in Rivers State. The research study became imperative to examine how rate of poultry manure could affect the production of okra. The experiment utilized three rates of poultry manure, 0-tons (control), 5-tonsha-1 and 10-tonha-1and the treatment combination arranged in a Completely Randomized Block Design (CRBD) replicated three times. Growth characteristics measured were, plant height, stem thickness, leaf area and number of leaves per plant while yield parameters measured were pod length, seeds per pod, total number of pods, pod yield per hectare. The results revealed that appropriate rate of poultry manure application in the production of okra has the capacity to increase okra growth and yield in Rivers State. The use of 10-tonha-1 of poultry manure performed better than other poultry manure rates and so it’s recommended that okra farmers in the study area should apply 10-tonha-1 for high quality and quantity production of okra in  Rivers State.

Abstract A field trial was conducted at the Teaching and Research Farm of the University of Ilorin during the 2015 and 2016 cropping seasons to assess the effect of tillage methods and poultry manure application on the growth and yield of sesame. The experiment was laid out as a split plot arrangement, fitted into a randomized complete block replicated thrice. The factors consisted of three tillage methods and four levels of poultry manure application (0, 5, 10, and 15 tha−1). The result revealed that tillage and poultry manure significantly (P<0.05) increased the growth and yield of sesame. Increasing the rate of poultry manure resulted in an increase in the net assimilation rate, relative growth rate, and crop growth rate. The yield in 2016 was higher than that of 2015 due to higher rainfall and residual effect of the previous cropping season. Yield per hectare was optimized using conventional tillage method and poultry manure at 15 tha−1. Although the conventional tillage and poultry manure treatments produced the highest yield, the control plot gave the highest cost and returns (return per investment) in the two years of study due to high cost of farm inputs. The result of the study further affirms farmer’s reluctance on the use of external inputs for yield enhancement in sesame.
