“…Insufficient nutrient supply at flowering stage of the plants due to immobilization (Petersen et al 2005) might have been the reason, which limited the remarkable effect of organic inputs. Limitation in plant growth due to nutrients immobilization particularly N and P had also been stated by Herencia et al (2011).…”

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.

“…The main features of organic farming are claimed to be sustainability, low-impact cropping methods, use of non-chemical fertilizers, and high-quality production; nevertheless, an objective and exhaustive assessment on the supposed higher nutritional value of organic food and on the benefits on consumers' health is still missing. Generally, organic food presents lower nitrates and higher content in vitamin C, but this is not true for all species; spinach, for example, accumulates more nitrates under organic farming than other farming systems [6][7][8]. A literature-based study including potato [7] revealed that organic vegetables are not significantly better than conventional ones and, in addition, experimental findings are often contradictory due to the influence of environmental factors and large genetic diversity among potato varieties tested.…”

Organic farming practices are commonly thought to reduce the environmental impact of agriculture and to preserve the naturalness of the products. Herein, we report the effect of crop management practices on nutritional and toxicological value of potato tubers. Comparative studies are often controversial and the results are dependent on genotype and methodological approach. Targeted analysis and "omics" strategies are discussed, pointing at the nutritional aspects and the corresponding biological and molecular processes involved. Organic farming supporters still do not accept the use of genetic modification to produce new varieties suited for organic agriculture and crop improvement by genetic engineering still sparks hot debate among various scientific and social factions whose major concern is the possible existence of unintended effects both on human and world health. In this context, the advent of "new plant breeding techniques" has reignited the discussion on genetic engineering and on the compatibility of the new technologies with an eco-friendly agriculture. Could cisgenic and genome-edited potatoes be new good options for organic agriculture? We discuss how these approaches can be used to address food security challenges and to overcome specific problems based on the biological characteristics of potato tubers, producing new varieties that can improve farmers' profit with a lower impact on public opinion. However, political, ethical, and social fears will probably persist much longer, mainly in Italy, historically a fiercely anti-GM country with a European leadership in organic food production and export.

“…The increase in juice content may be due to an interactional effect of mixture of manures and inorganic NPK applied through treatment T4 which might have improved cell elongation, cell thickening and fruit development, resulting in better ripening with more succulent fruits. Several reports have indicated that manure and fertilizer combinations in strawberry have led to the production of softer fruits Karma Beer et al, (2017), Rayees et al, (2015), Ayesha et al, (2011), Herencia et al, (2011), Singh et al, (2010, Singh et al, (2009), Mahadeen et al, (2009), Ghaderi et al, (2008; Odongo et al, (2008) and Macit et al, (2007). The maximum TSS (14%) was found in treatment T5 and the minimum (9%) in treatment T1, likewise total sugar was highest in treatment T5 and lowest in treatment T1 (Table 2 and Figure 3 and 4).…”
