The aim of this study was to investigate impact of vermicompost on chemical and biological properties of an alkaline soil with high lime content in the presence of plant under the open field conditions in semiarid Mediterranean region of Turkey. The study also included farmyard manure and chemical fertilizers for comparison and was conducted in two consecutive growth seasons in the same plots to observe any cumulative effect. Plots were amended with fertilizers in different rates and celery (Apium graveolens L. var. dulce Mill.) was grown as the test plant. In general, vermicompost appeared to be more effective to increase organic matter, N, P, and Ca compared to farmyard manure. Soil alkaline phosphatase and β-glucosidase activities, especially in the second growth season, were significantly elevated by the vermicompost application. Urease activity, however, appeared not to be influenced by the type of organic fertilizer. A slight but statistically significant difference was detected between organic amendments in terms of number of aerobic mesophilic bacteria with vermicompost giving the lower values. Results showed that, in general, vermicompost significantly alters chemical and biological properties of the alkaline soil with high lime content during celery production under field conditions compared to farmyard manure and that it has a high potential to be used as an alternative to conventional organic fertilizers in agricultural production in the Mediterranean region of Turkey.

This study was conducted to investigate direct short-term impact of vermicompost on some soil biological properties by monitoring changes after addition of vermicompost as compared to farmyard manure in an alkaline soil with high lime content from semiarid Mediterranean region of Turkey. For this purpose, mixtures of soil and organic fertilizers in different doses were incubated under greenhouse condition. Soil samples collected in regular intervals were analyzed for biological parameters including dehydrogenase,β-glucosidase, urease, alkaline phosphatase activities, and total number of aerobic mesophilic bacteria. Even though soil dehydrogenase activity appeared to be dose-independent based on overall evaluation, organic amendments were found to elevate dehydrogenase activity when sampling periods are evaluated individually.β-glucosidase, urease, alkaline phosphatase activity, and aerobic mesophilic bacterial numbers in vermicompost treatments fluctuated but remained significantly above the control. A slight but statistically significant difference was detected between organic amendments in terms of urease activity. Vermicompost appeared to more significantly increase bacterial number in soil. Clearly, vermicompost has a potential to be used as an alternative to farmyard manure to improve and maintain soil biological activity in alkaline calcareous soils from the Mediterranean region of Turkey. Further studies are needed to assess its full potential for these soils.

Fertility improvement of Ultisol is inevitable to increase growth and yield of chili pepper since the nutrient availability and organic matter of this soil is relatively low. Application of organic fertilizer will enhance microorganism activity in soil, thereafter will improve the availability of nutrients as well as other chemical, physical, biological properties of the soil. Most of manure releases nutrient quite slowly; therefore, addition of nitrogen to soil is expected to speed up the availability of nutrient to plant. Weed based organic fertilizers from Wedelia (Wedelia trilobata) and Siam weed (Chromolaena odorata) biomass have potential to substitute inorganic fertilizer. The objective of the experiment was to compare the effects of weed based organic compost and dry leaves compost with or without addition of nitrogen fertilizer on growth and yield of chili pepper. The experiment was carried out using Completely Randomized Design (CRD) with treatments of 200 kg urea ha-1; Wedelia compost (WDC) 20 ton ha-1; WDC 15, 10, and 5 ton ha-1 with addition of 200 kg urea ha-1 respectively; Siam weed compost (SWC) 20 ton ha-1, SWC 15, 10, and 5 ton ha-1 with addition of 200 kg urea ha-1 respectively; and dry leaves compost (DLC) 20 ton ha-1, DLC 15, 10, and 5 ton ha-1 with addition of 200 kg urea ha-1 respectively. The result revealed that composts with or without addition of nitrogen fertilizer had similar responses on the growth of chili pepper. Wedelia and Siam weeds compost at 20 ton ha-1 tended to give better yield of chili pepper as compared to application of urea alone. This result indicated that weed based organic fertilizers could substitute nitrogen fertilizer.

Consumer demand for cleaned squid generates a substantial amount of waste that must be properly disposed of, creating an economic burden on processors. A potential solution to this problem involves converting squid byproducts into an organic fertilizer, for which there is growing consumer demand. Organic fertilizers are reputed to offer advantages that synthetic fertilizers cannot provide, such as increasing soil water- and nutrient-holding capacity and promoting the growth of beneficial soil organisms. To evaluate the effectiveness of hydrolyzed squid waste as an organic fertilizer, we quantified soil fertility and turfgrass quality on perennial ryegrass turf (Lolium perenne L.) amended with two types of fertilizer: squid-based (SQ) or synthetic (SY). Field plots were established on an Enfield silt loam in Kingston, RI, and liquid (L) or granular (G) fertilizer formulations of squid or synthetic fertilizers were applied at 0, 48, 146, and 292 kg nitrogen/ha/year. Soil physical, chemical, and biological properties were determined monthly and turfgrass quality was determined periodically during the growing season in 2008 and 2009. Squid hydrolysate applied as a liquid (SQL) and granular (SQG) fertilizer consistently provided high-quality, uniform turf when compared with synthetic fertilizer applied at the same rate. Soil concentrations of NO3, NH4, PO4, pH, moisture, soil organic matter, C:N ratio, and levels of trace metals were unaffected by fertilizer type, formulation, or rate throughout the two-year study. Both squid-based organic fertilizer formulations gave significantly higher microbial activity rates than their synthetic counterparts regardless of application rate. Conversion of squid processing byproducts into fertilizer has the potential to improve turfgrass quality while providing a sustainable solution to waste disposal problems in the seafood processing industry.

Abstract To evaluate the effect of different micronutrients (Mn, Fe, Zn) and farmyard manure (FYM) on the vegetative, phenological, and achene yield components of sunflower a field experiment was conducted in Maragheh, North West of Iran during the growing season 2018–2019. The treatments were arranged in a split-plot design- with three replicates. The main plots assigned to two levels of FYM (0 and 20 t ha−1) and sub plots assigned to the recommended dose of three micronutrients (Mn, Fe, Zn). The results revealed significant improvements in the growth and yield of sunflower due to the main and interaction effects of farmyard manure and inorganic fertilizer application. The highest number of leaves and the highest leaf area was observed in a plant grown by FYM + Zn. However, there was no significant difference between micronutrients under inorganic condition (without FYM application). The highest leaf relative water content (RWC), plant height, internode distance, and chlorophyll was recorded for plants grown by Fe or Zn under FYM applied condition. Application of FYM and micronutrients reduced the number of days to flowering. However, the application of FYM significantly delayed plant maturity. Achene number per head, 100-achene weight, achene length, achene width, achene oil percent, achene yield, and harvest index significantly increased with the application of FYM and the best performance was in a plant grown by FYM + Zn and FYM + Fe. The percentage of hollow and empty achene was significantly reduced by the application of FYM. Combined applications of FYM and micronutrients has become an increasingly common practice.

ABSTRACT Cucumber is a horticultural product which becomes one type of fruit vegetable and has a great demand in the community. The potential productivity of cucumber itself is still relatively low, that is in 2016 amounting to 10.19 tons / ha, this also occurs in the productivity of local cucumbers which are quite low, but until now there are still many cultivated by farmers in Jember area. In addition to the increase in production, it is also necessary to improve the quality of fruit which affects the competitiveness of the selling value of cucumber fruit. Regarding the increase in production and quality of fruit, the efforts need to be made to improve cultivation methods. One of them is the use of organic fertilizers which contain more complex nutrients and the application of plant regulators. One of the organic fertilizers, vermicompost organic fertilizer, is the result of decomposition by worms which affects plant growth and the application of gibberellins (GA3), it can improve fruit quality and increase the percentage of fruit formation. This study aimed to determine the effect of using the combination of vermicompost organic fertilizer and the addition of giberelin (GA3) on cucumber plants by using a randomized group design (RGD) with 2 factors and 3 replications. The first factor was giving vermicompost organic fertilizer, namely (K0) 0 g/plant (control), (K1) 120 g/plant (3 tons/ha), (K2) 240 g/plant (6 tons/ha), (K3) 360 g/plant (9 tons/ha). The second factor was the addition of gibberellin concentrations (GA3), namely (G0) 0 ppm, (G1) 50 ppm, (G2) 100 ppm and (G3) 150 ppm. The data obtained were then analyzed using variance analysis, if between treatments had a significant difference, then further tests were carried out by using Duncan's Multiple Distance Test at the level of 5%. The best treatment ofvermicompost organic fertilizer dosage and giberelin hormone concentration was found in the treatment of 360 g/plant or 9 tons/ha (K3) at the optimal concentration of 100 ppm giberelin hormone. Key words: Cucumber, Vermicompost fertilizer, Gibberellin (GA3), Production and Quality of Fruit ABSTRAK Mentimun merupakan produk hortikultura yang menjadi salah satu jenis sayuran buah yang banyak diminati oleh masyarakat. Potensi produktivitas mentimun sendiri masih tergolong rendah yaitu pada tahun 2016 sebesar 10,19 ton/ha, hal ini juga terjadi pada produktivitas mentimun jenis lokal yang cukup rendah, namun sampai saat ini masih banyak dibudidayakan oleh petani pada daerah Jember. Selain peningkatan terhadap produksi, perlu juga dilakukan perbaikan kualitas buah yang berpengaruh pada daya saing nilai jual buah mentimun. Terkait peningkatan produksi dan mutu buah, maka perlu dilakukan upaya perbaikan cara budidaya. Salah satunya adalah penggunaan pupuk organik yang mengandung unsur hara yang lebih kompleks dan pengaplikasian zat pengatur tumbuhan. Salah satu pupuk organik yaitu pupuk organik kascing, yang merupakan hasil dekomposisi oleh cacing yang berpengaruh terhadap pertumbuhan tanaman dan aplikasi giberelin (GA3) yang mampu meningkatkan kualitas buah dan meningkatkan persentase pembentukan buah.

Global warming is the leading cause of the extreme meteorological events increase in the last three decades. Increase of annual average air temperature and temperature values during winter and early spring has been recorded in comparison to the (1961-1990) referent period in Plovdiv region. The lettuce development was researched in a greenhouse in the Agricultural University- Plovdiv. During the lettuce growth six different variants were used: no fertilizer, one chemical, and four organic fertilizers. The effect of the different organic fertilizers was studied through specific physiological parameters and productivity. This paper analyzed changes in functional activity of the plant photosynthetic apparatus and productivity of variants with different fertilizers in an unheated greenhouse. The ratio between photosynthetic active radiation (PAR) and quantum yield (qY-Fv/Fm) of PS II was determined to be more optimal in dark-adapted leaves for the organic fertilizer variants, compared to the no fertilizer variant. The lower and significant difference was observed in the values of the minimal fluorescence Fo in reaction centers of PS II after the dark-adaptation of leaves for organic fertilizer variants compared to the no fertilizer variant. Higher values of chlorophyll content index (CCI) were estimated for organic and chemical fertilizers compared to the no fertilizer variant. All variants fertilized with organic and biofertilizers comply with the quality standard from the beginning to the end of harvesting.
