Use of sugarcane industrial by-products for improving sugarcane productivity and soil health

Purpose An investigation was carried out to evaluate the effect of the integrated application of organic and inorganic fertilizer effect on Bradyrhizobium effectiveness on nodulation and yield of peanut at the major growing areas of Eastern Ethiopia, Babillae and Fedis sites. Methods Systemic combination of compost, manure, Bradyrhizobium inoculation and NP application was laid out in Randomized Complete Block Design with three replications. Results The result showed that Bradyrhizobium integrated with organic inputs significantly improved the nodule number at Babillae while Bradyrhizobium when applied with DAP resulted in a significant increase of nodulation at Fedis site. The highest total biomass and total pods weight at both sites were found to record when Bradyrhizobium integrated with manure and compost. Integration of Bradyrhizobium, manure and compost at Fedis and Bradyrhizobium with manure at Babillae was found to increase the kernel yield by 44 and 66.6% over the control check, respectively. Integration of Bradyrhizobium, manure and compost at Babillae and Bradyrhizobium with starter N at Fedis significantly increased plant N accumulation. The effect of organic and inorganic application on soil N and organic carbon content was not significant at Fedis, but the slight increase was observed in Babillae site. A significant increase in the soil available P by organic and/or DAP application was found in either of the experimental sites. Conclusion Organic fertilizer when integrated with Starter N and DAP is better in improving the effectiveness of Bradyrhizobium, nodulation and yield of peanut in either of the sites.

Organic and inorganic fertilizer application enhances the effect of Bradyrhizobium on nodulation and yield of peanut (Arachis hypogea L.) in nutrient depleted and sandy soils of Ethiopia

“…Because organic manures are characterized by slow release of nutrients, the complementary applications of organic manures with fast nutrient release-characterizing mineral fertilizers have been advocated. The beneficial effects of this practice in terms of improved crop productivity, soil fertility and sustainability, and balanced plant nutrition have been reported (Rady 2011a;Moyin-Jesu 2015;Riaz et al 2015;Semida et al 2015;Dotaniya et al 2016;Kalaivanan and Hattab 2016;Kumar and Chopra 2016). In addition, application of FYM and green manures have positive effects on the soil characteristics (Kumar et al 2014;Suja and Sreekumar 2014).…”

Purpose The effect of a novel organo-mineral fertilizer (OMF) compost, as a partial alternative to mineral fertilizers, on soil characteristics, growth, physio-biochemical attributes, Cd 2? and NO 3 -concentrations, and yields of Phaseolus vulgaris L. plants grown under salt stress was investigated. Methods Six organic and mineral materials were well mixed with water and composted in a polyvinyl house in a concrete trench of size 4 9 5 9 2 m (W 9 L 9 D), respectively. The moisture content was maintained at 50-60% throughout the active composting period by frequent checking. The mixture was turned at 7-day intervals for about 2 months to maintain porosity. This OMF compost was applied for the tested saline soil at 10, 20 and 30 ton ha -1 while reducing the recommended NPK to 50%. In addition,100% NPK was applied as a control to achieve the purpose of this study. Growth characteristics, quantitative and qualitative yield, Cd 2? and NO 3 -concentrations, and physio-biochemical attributes in common bean plants were assessed. Results Addition of OMF compost improved the soil chemical and physical properties. Application of OMF compost at a rate of 20 ton h -1 , as an alternative to 50% of the recommended dose of mineral-NPK fertilizers, significantly decreased the concentrations of Cd 2? and NO 3 -in plant leaves, pods and seeds, showing the same growth characteristics, and pod and seed yields compared to the control (100% of mineral-NPK fertilizers). This treatment also improved all determined physio-biochemical attributes and tested soil characteristics compared to the control. Conclusion The benefit of this OMF compost, as a partial alternative to chemical fertilizers, demonstrated the validity and possibility of sustainable agronomic performance of common bean using locally available recycled organic materials for manufacturing the studied OMF.

“…Intensive use of soils, specifically those oriented to horticultural production, has caused the decrease of organic matter and nutrient; that has been identified as one of the most important threats to the quality of soils (Bevacqua and Mellano 1994;Maynard 1995;Khoshgoftarmanesh and Kalbasi 2002;Hu and Barker 2004;Maftoun et al 2004;Campitelli and Ceppi 2008;Amusan et al 2011;Kabirinejad and Hoodaji 2012;Sohrabi et al 2013;Giannakis et al 2014;Rajaie and Tavakoly 2016;Dotaniya et al 2016;Kalaivanan and Hattab 2016).…”

Purpose Farming production in the lower part of Río Negro Valley (Argentina) has increased considerably during recent years, causing soil degradation and, specifically, decreasing the organic matter contents. This fact requires recovery measures, as organic amendments for soils, to improve its quality. The marked objectives for the present research is to evaluate compost as organic fertilizer, based on a mix of onion waste and bovine manure. Methods The experiment was carried out in a completely randomized design, involving five treatments and one control, with ten copies of each one. Tests were performed in a greenhouse, using flowerpots and experimental plots, in a typical soil of the region (Aridisol), pH 8.3 and 2.2% of organic matter, mixed with different compost dosages (20, 40, ) and the chemical treatment, Urea (0.26 Mg ha -1 ). A horticultural farming of 1 lettuce was sowed (Lactuca sativa). A conventional handling was carried out for the whole cultivation period, and at the end was harvested. Ten plants per plot were taken and were determined total fresh weight, aerial part fresh weight, root part fresh eight. In the dry controls total dry weight, aerial dry weight and root dry weight was determined. Results Results show, with an error (p \ 0.05), significant differences in the fresh weight per plant calculated, between treatments and control; a noticeably greater effect can be observed in the treatments with 6 and 8 kg m -2 compost amending and urea treatment. There is no evidence of the existence of significant differences (p \ 0.05) between treatments and control, according to the values obtained for root size as well as aerial dry weight and root dry matter. Conclusions It can be concluded that the addition of organic fertilizer to soils, has positive effect on the Fresh weight of the plant, recommending the use of doses of 6 kg m -2 while the dose of 8 kg m -2 could replace the use of chemical fertilizers such as Urea.
