El-Farghal, W. M.; Wafaa M.T. El-Eterand A. M. Morsy ( 2019). Influence of Successive Additions of Some Organic Conditioners and Mineral Fertilizers on Soil Chemical Properties and Wheat Yield in Sandy Soils. Nature and Science 2019;17(4)
Abstract: Two field trials were conducted in sandy soil of the farm at Ismailia agriculture Research Station during successive winter seasons (2011 / 2012 and 2012 / 2013) cultivated with wheat crop (Giza 168) under sprinkler irrigation system to study the influence of successive additions of some organic conditioners such as molasses, compost tea and their combinations in presence of NPK mineral fertilizers on soil properties and wheat yield components. The experiment was laid out in a split-plot design with four replications, the main plots rates of mineral fertilizers (50 and 100 % of the recommended NPK dose) whereas the sub main plots treatments included the molasses (2.5 and 5 ton fed.-1) and compost tea (400 and 600 L fed.-1) and their combinations. All organic conditioners were applied every 15 days until booting growth stage of wheat plants at two growth seasons. The obtained results indicated that, at both seasons, the successive addition of molasses and tea compost either alone or their combinations in presence of mineral fertilizers at 50 or 100% to the sandy soils led to a decrease in soil pH values, while increased soil EC values, organic matter content (OM), cation exchange capacity (CEC) and available contents of N, P and K as well as increased wheat yield parameters. Moreover, the application of molasses (M2) 5.0 ton fed-1 combined with compost tea (CT2) 600 L fed-1 at 100 % of NPK were high significant effect on the soil chemical properties as compared to other treatments and control. In addition, wheat yield components such as plant height, spike length , weight of 1000 grain and biological yield as well as protein content, P and K concentrations in wheat grain were significantly increased by addition of all organic conditioners either alone or associated with each other in the presence of NPK mineral fertilizers (50 and 100 % ). Moreover, the highest mean values of straw and grain yields were (4.70 ton fed-1) and (13.83 rd. fed.-1), respectively, when applied 100 % of NPK fertilizers associated with (M2 + CT2) as compared to control treatment. In general, these results suggest that the successive addition of molasses and compost tea either alone or mixed with each other in the presence of mineral fertilizers at 100 % of recommended dose to the sandy soils had a positive impact on some soil properties and so on the wheat yield components
