“…US267, USM and USHZ significantly increased the stem diameter and plant height of substrate-grown cucumbers. Our findings were consistent with the results of Selvakumar 34 who observed that microbial fertilizers increased the beneficial microorganisms in the rhizosphere and increased plant growth. B. subtilis and Trichoderma were reported as two of the most important plant growth-promoting organisms in commercial agriculture that increased plant growth and influenced the taxonomic composition in the rhizosphere 35 – 38 .…”

Reductions in the quality and yield of crops continuously produced in the same location for many years due to annual increases in soil-borne pathogens. Environmentally-friendly methods are needed to produce vegetables sustainably and cost effectively under protective cover. We investigated the impact of biofertilizers on cucumber growth and yield, and changes to populations of soil microorganisms in response to biofertilizer treatments applied to substrate or soil. We observed that some biofertilizers significantly increased cucumber growth and decreased soil-borne pathogens in soil and substrate. Rhizosphere microbial communities in soil and substrate responded differently to different biofertilizers, which also led to significant differences in microbial diversity and taxonomic structure at different times in the growing season. Biofertilizers increase the prospects of re-using substrate for continuously producing high-quality crops cost-effectively from the same soil each year while at the same time controlling soil-borne disease.

“…This result indicates that the macronutrient content of the red pepper fruit incorporating with hairy vetch appears similar levels to chemical fertilizers, consistent with those found in previous studies (Muchanga et al, 2017;Selvakumar et al, 2018b). In this study, even though N application was reduced with incorporating hairy vetch, N uptake of fruit and N use efficiency of red peppers were no significant different compared to chemical fertilizer treatment group (Tables 5 and 6).…”

Long-term use of chemical fertilizers will impair the physical and biological properties of facility soil environment for crop cultivation. The effective way to reduce the use of chemical fertilizers and improve soil properties is known to utilize green manure crops. The objectives of this study were to investigate the growth characteristics and yields, to analyze the nutrient utilization efficiency, and to measure the effect of soil microbial activity through enzyme activity when incorporating hairy vetch (Vicia villosa Roth) with facility-grown peppers (Capsicum annuum L.). Four different fertilizer treatments were applied: no fertilizer (CON), chemical fertilizer (CF), hairy vetch and 0.5N additional fertilizer (HV0.7N), and hairy vetch and N additional fertilizer (HVN). Soil and plant nutrient content, plant nutrient use efficiency, and soil enzyme activity were analyzed in each treatment. All fertilization treatments significantly increased total fresh weight and fruit dry weight of red pepper compared to the control (CON). However, total fresh weight, macronutrient uptake, and P and K use efficiency were significantly lower in the HV0.7N treatment than the CF and HVN treatments. The HV0.7N and HVN treatments significantly increased soil dehydrogenase activity during entire cultivation period. Whereas, urease and β-glucosidase activity were significantly increased only in the early stages of cultivation. These results suggest that the incorporation of hairy vetch residue as organic fertilizer in cultivation facility, can increase enzyme activity in the soil. Moreover, the yield of red pepper fruits was not small compared to that of CF treatment, even if only a lower amount of nitrogen was applied.

“…Previous studies (Ouedraogo et al, 2001;Birkhofer et al, 2008;Selvakumar et al, 2018) and our results confirmed that compost application increases the soil organic matter content. Although P and K contents were higher in the compost than in the CF, the P and K contents of the plants were similar in both treatments, and the compost application resulted in increased soil-available P and K after red pepper harvest.…”

Green manures and compost have been widely used as alternatives to chemical fertilizers. The present study aimed to assess the changes in red pepper (Capsicum annuum) yield, soil properties, and soil enzyme activities under organic and inorganic nitrogen fertilizer management. The treatments used here were chemical fertilizer (CF), hairy vetch (Vicia villosa L.) residue with CF (HV+N), and livestock compost (LC). The same amount of nitrogen was applied in all treatments. In general, all fertilization treatments significantly increased red pepper growth, yield, and macronutrient content compared to the control (CON); however, no differences were observed among the fertilization treatments. The phosphorous uptake rate was significantly higher in the HV+N treatment than the LC treatment. Post-experiment soil analysis showed that the LC application significantly increased soil organic matter, electrical conductivity, and available phosphorus content compared to the CF or HV+N treatments. The CF treatment significantly increased the nitrate content in the soil. The HV+N and LC treatments significantly increased soil dehydrogenase activity. The CF treatment resulted in significantly higher urease activity in the soil; whereas there were no differences in βglucosidase and phosphatase enzyme activities among the treatments. These results suggest that the addition of hairy vetch residue to inorganic fertilizer, or a compost application, can increase enzyme activities while providing similar crop yield to those obtained with a chemical fertilizer application.
