Productivity assessment of two different management systems in sub-divided four different gradients (Published)
Watersheds are naturally productive but most ecologically vulnerable section of the landscape. Productivity assessment of two contrasting watershed were studied in Amawbia south east, Nigeria using amaranthus as test crop under field and pot experiments. The experiments were arranged in randomized complete block design (RCBD) and complete randomized design (CRD) respectively in managed and unmanaged system of the watershed with NPK at the rate of 150kg/ha. Findings from the study showed significant differences (P < 0.05) among the slopes, managements, slope and management as well as natural environment and NPK in all the parameters assessed. Higher values were recorded in managed system in all the parameters and values obtained from NPK were observed to be higher than the values obtained from natural environment. Natural environment of the four slopes studied in managed plot significantly recorded increased growth and yield of amaranthus than the unmanaged plots. Thus, the findings of the study are evidence that sustainable management of soil and water resources is based on the judicious and scientific management of all landscape units within a watershed. As land degradation beyond the point of no return, pollution and eutropication of water and environment are all traceable to poor and mismanagement of landscape units within a watershed.

Effect of Organic and Inorganic Fertilizers on Yield and Economic Return of Acha (Digitaria Spp) Varieties in Lafia, Nigeria (Published)
These studies were conducted at the Teaching and Research farm, College of Agriculture, Lafia, Nasarawa State, Nigeria during the wet seasons of 2013 and 2014. To determine the effect of poultry manure and NPK fertilizer on growth and grain yield of Acha varieties and profit margin for using these inputs in Lafia, Nasarawa state, Nigeria. The experiment was carried out in a randomized complete block design, replicated three times. The results showed that application of poultry and NPK fertilizer rates significantly enhance growth parameters in both two seasons. 10/ha of poultry manure and 120kg/ha of NPK produced plants with highest number of tillers (12.93 and 13.24); whil D. eburua variety produced the tallest plant (14.78 and 16.24) in both years. Application of 10t/ha of poultry manure produced the highest grain weight of 0.98t/ha and 1.27t/ha; while NPK fertilizer rate at 120kg/ha also produced the highest grain weight of 1t/ha and 1.21t/ha in both years. All these grain weight are statistically at par with application of 5t/ha of poultry manure and 60kg/ha of NPK fertilizer, but lower than the control in both years. Varieties also had a significant effect on the grain yield of Acha. Digitaria exilis proved its superiority agains D. eburua by producing the highest grain weight of 1.31t/ha and 1.52t/ha in both years. Interaction between poultry manure and NPK did not produce ant significant effect on the grain weight of acha in both years. The total revenue (TR) under organic manure was N54,775.00 and N54,950.00 under inorganic (NPK) fertilizer. The gross margin (GM) was estimated to be N27,575 and N25,900.00 under organic manure and inorganic fertilizer respectively. Various ratios calculated gave a positive value which shows that Acha production in the area is viable and profitable.

EFFECT OF ORGANIC AND INORGANIC FERTILIZER ON THE YIELD AND NUTRIENT COMPOSITION OF JUTE MALLOW (Published)
Soil fertilization influences crop yield and nutrient composition of the leafy vegetable. An experiment was conducted to evaluate the effects of organic and inorganic fertilizers on the yield and nutrient composition of Jute Mallow. The treatment consists of eleven fertilizer applications (2.5t/ha OBF, 5.0t/ha OBF, 2.5t/ha OBF +50kg NPK, 2.5t/ha OBF+75kg NPK, 2.5t/ha OBF+100kg NPK,5.0t/ha OBF+50kg NPK, 5.0t/ha OBF+ 75kg NPK,5.0t/ha OBF+100kg NPK,50kg NPK,75kg NPK,100kg NPK ) and a control. Jute seeds were sown into the pots at the rate of two plants per stand. The experiment was arranged in a Complete Randomised Design (CRD) with three replicates. Organic sunshine fertilizer was applied two weeks before planting to allow the fertilizer to mineralize in the soil for prompt absorption of nutrients after planting. Two weeks after planting, the supplementary application of inorganic fertilizer was carried out using compound fertilizer (N: P: K: Mg 12:12: 17: 2).The results demonstrated that at eight weeks after planting (8WAP), plant heights levelled-out across the treatments applied. There was significant difference(p<0.05) in the number of leaves per treatment but a comparable highest number of leaves was found in pots treated with 2.5t/ha OBF+50kg NPK and 5.0t/ha OBF +75kg NPK.Whereas the control pots had the least number of leaves. The effect of fertilizer application significantly influenced the nutrient composition of Jute leaf number, yield performance, plant height, and stem diameter. There was a positive correlation between fertilizer application, crop yield and nutrient composition of jute mallow.
