Two years Evaluation of Four contrasting organic wastes on soil productivity and maize yield in Ultisol at Igbariam soil south east Nigeria (Published)
Famers since history in agriculture use animal waste to conserve their soil and improve crop yield. A randomized complete block design (RCBD) was set up to study the effect of four (4) contrasting animal wastes on soil productivity and maize grain yield for two consecutive years in Igbariam soil south east Nigeria. The waste comprising of cow dung (CD), pig dropping (PGD), poultry droppings (PD) and goat droppings (GD) were applied at rate of 24kg/plot (equivalent to 20 tha-1) in the first year and their residual effect tested in the second year cropping. Results showed that application of animal wastes significantly (P < 0.05) enhanced the soil properties and yield parameters of maize tested, for the 2 years study. The immediate effect of animal wastes in improving the soil pH of the amended plots gave corresponding increases in the values recorded for the soil parameters tested with a reduction in bulk density relative to the control plot for two consecutive years of study. Maize grain yield showed highest value (3.54 tha-1) and plant height 163.9 cm in PD first year cropping but second year cropping result depicted PGD to record highest maize grain yield value (1.96 tha-1) among the other treatments. The findings from the study showed that the use of animal wastes in crop production system can improve the productivity of soil and increased crop yield.
Effect of Adding Different Organic Fertilizers in the Absorption of Some of Nutrient Elements from Soil in Properties of Plant Growth and Yield of Cucumber Plant (Published)
The experiment was conducted in one of the greenhouses of the College of Agriculture – University of Wasit for spring season 2013 to study the effect of adding some organic fertilizers in the growth of cucumber plant . The experiment included 6 Treatments : (T1 comparative treatment ( without any addition ), T2 adding ground for Fertilizer organic Humic plus by 250 g / Dunam , T3 addingthe organic nutrient Vegeamino Foliar with concentration of 1 ml / l , T4 adding compost Humic plus Foliar concentration of 3 g / l , T5 adding organic fertilizer Humic plus Foliar + Vegeamino and T6 adding organic fertilizer Humic plus ground addion + Vegeamino) . The experiment was carried out using a Randomized Complete Block Design (RCBD) with three replications and tested moral differences between averages , according to the less significant moral differences between averages and the probability of 0.05.The results showed a significant superiority of treatment T6 ( Adding Organic Fertilizer Humic plus Add ground + Vegeamino Foliar) in the dry weight of the plant and the percentage of chlorophyll , nitrogen ,and potassium , and holds rate per plant , and the sum total of the plastic house as it was ( 23.99 g , 52.40 % , 4.50% , 2.970 % , 0.641 kg 0.721 kg) , respectively, with no significant difference for treatment T2 in the percentage of chlorophyll , nitrogen , potassium and rate yield per plant sum total of the plastic house which recorded ( 51.19 % , 4.48 % , 2.960 % , 0.585 kg 0.681 kg). From this study , we are conclude that using Organic Fertilizer Humic plus as ground applied + Vegeamino as foliar applied can be enhance from cucumber growth and increase the yield it .
