In this work are determined the prospects of application new complex fertilizer chelate “Naliv” for apple plants non-root nutrition in connection with optimization of economic yield formation in the Southern Russia organic plantations. The field experiment was carried out in the organic apple tree plantations of the educational farm "Kuban" of the KubSAU, planted in 2002. The experimental field soil is leached chernozem. Trees foliar dressing was carried out with organic fertilizer 40-45 days before harvest. Control variant was trees treatment with water. The accumulation of glucose and fructose, associated with a significant (1.4 times) increase in their average weight, activate in ripening fruits under fertilizer application as a late-summer foliar dressing. Equally, the economic yield increases by 14% compared to control value. The fertilizer application accelerates the generative apple bud dormancy beginning and, accordingly, dormancy ending. An increase in the abscisic acid content in generative buds in late autumn, initiated by the fertilizer action, plays a certain role in achieving this effect. Equally, the plants resistance to low temperatures of the spring increases. Thus, favorable conditions are created to improve the commercial quality of fruits and optimize fruiting in adjacent years under fertilizers application in organic apple plantations.

Postharvest Quality

Long-term use of inorganic fertilizers on leafy vegetables can increase soil acidity, harmful to the environment and leaving bad effects on human health. Organic fertilizer application is one of the safer alternatives with many beneficial effects by supplying nutrients for plant growth, environmental-friendly and producing an optimum quality of vegetables. Different organic amendment such as vermicompost, biochar and microbial compost has different effect on plant growth performance since good bacteria could improve structure of the soil and nutrient absorption. Therefore, this study aims to evaluate the effects of organic fertilizer on the growth performance and postharvest quality. The experimental design during planting was conducted in randomized completely block design with a factorial arrangement of treatmentswhile for postharvest quality study was conducted in completely randomized design. Organic fertilizer of vermicompost (110 g/plant), biochar (100 g/plant), microbial compost (80 g/plant) and chicken manure (37.5 g/plant) were treated on Pak choy two times on day 10 and day 24 after transplant. This research revealed the plant growth including plant height, leaf number and leaf length of Pak choy in all treatments were increased as growing stage increased. However, at the end of growing stage, microbial compost and vermicompost resulted in the highest of growth characteristics. In terms of postharvest quality, microbial compost showed the highest fresh weight and premium quality. This study proved that microbial compost at 80 g/plant exhibited optimum growth performance and the best postharvest quality of Pak choy.

Nowadays soils for vegetable growing are poor in humus because the possibility of using stable dung is limited. The application of Lignofert organic carbonaceous fertilizer made of ground lignite seems to be a solution. It is intended as a fertilizer for the field or greenhouse growing of vegetables, as a component to composts, soil substrates and likewise. Lignofert effects on the formation of lettuce yield, weight of heads and NaNO<sub>3</sub> content were studied in 2003 to 2005. Head lettuce grown in a greenhouse and in field conditions was a biological material. Average lettuce yields and average weight of heads in 2005 were statistically highly significantly higher in variants with Lignofert in comparison with the control variant grown in the greenhouse and in the field. The Lignofert effect on nitrate content in lettuce heads was not proved statistically. &nbsp;

Growing environmental impact of conventional farming practices, gradually impacts soil structure and biological balance. This has forced the development of alternative practices to reduce and mitigate these effects. Types of fertilizers influence the quantity and quality of production. Following this idea, in 2016, in a crop of melon in a polyethylene tunnel, Lignohumat organic fertilizer was used, a granular humic product, which was applied during vegetation, in three stages and three fertilization doses: 100; 150 and 200 g/ha. Melon plants (Charentais variety) fertilized with Lignohumat at different doses showed positive results compared to the unfertilized variant. Results showed that application of the 150 g/ha dose significantly improved (P ≤ 0.05) the average number of fruits/plants, their average weight, fruit/plant production and the production/m2 but also the quality of fruits: soluble dry matter – 8.55%, total dry matter – 12.12%, reducing sugars – 3.40%, vitamin C - 21.12 mg/100 g, carotene - 36.42 mg/100 g f.m and antioxidant activity of 175.92 μMTE/100 g (ABTS method) and 228.16 μMTE/100 g (DPPH method). Antioxidant activity was evaluated using 2.2-diphenyl-1-picrylhydrazyl (DPPH) 2.2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS). Significant positive correlations were identified for very importants parameters.

To achieve food-self sufficiency in Indonesia, it is necessary to apply sustainable agriculture practices to improve soil quality. Most of paddy fields have been applied with chemical fertilizers intensively for more than 40 years without the addition of organic matter.  The purpose of this study was to understand the effects of lignite-based organic fertilizer application on the quality of paddy soil and yield of rice. The study was conducted in April until August 2014 in the irrigated rice fields in Belitang, Ogan Komering Ulu Timur District. The study was arranged in a Factorial Randomized Block Design, with 9 treatment combinations and 3 replicates. The first factor was the types of fertilizers, consisting of recommended chemical fertilizers (250 kg urea ha-1 + 150 kg SP36 ha-1 + 50 kg KCl ha-1), organic fertilizer from plant residue at 5 Mg ha-1,  and lignite-based organic fertilizer (namely Baranik fertilizer) at 0.75 Mg ha-1.  The second factor was rice varieties, consisting of Mentik Wangi, Gogo Aromatik and Ciliwung. The application of Baranik fertilizer at 0.75 Mg ha-1 has improved the quality of paddy soil with the increase of organic-C content from 1.44% to 2.90%. Application of Baranik fertilizer at 0.75 Mg ha-1 has increased the vegetative components and the yield of rice about 7.17 Mg ha-1 compared to the organic fertilizer from plant residue, but the yield is still the same as that in the recomended dosages of chemical fertilizers.  Among the rice varieties, the yield of Ciliwung variety was higher than other varieties, i.e. 7.62 Mg ha-1.  The yield of Gogo Aromatik variety is significantly lower than that of Ciliwung variety.  Baranik organic fertilizer can be used to improve soil fertility for food security purpose.

Fertirrigation of melon still presents problems in relation to the type of the fertilizer used, mainly the biofertilizers. This experiment, installed in Uberaba, MG, Brazil, in a plastic module greenhouse of 768 m², tested treatments consisting of the conventional mineral fertirrigation and the organic fertirrigation, using two frequencies: daily and weekly. The best yields were obtained with daily fertilizer application, with superiority in relation to biofertilizers, with yield of 45.5 t ha-1 of fruit. This value was higher as compared to chemical products, that lead to a yield of 42.4 t ha-1. The weekly fertigation had lower productivities, and in this case, the biofertilizers also overcame the mineral, on the average 2.0 t ha-1. The best melon soluble solids values were obtained for the daily application of fertilizers, and the best treatment (P < 0.05) was the organic daily fertigation, with values of soluble solids content of 13.60° brix, followed by the daily chemical fertigation, with values of 12.52°. On the average, the amounts of soluble solids in melon were superior to the average found for Brazilian melons. Differences were not verified among the treatments for the variables pulp thickness and fruits pH. Regarding the peel thickness, the application of organic fertilizer sources presented a slight superiority in relation to chemical fertilizer treatments. No differences were verified among treatments in relation to the amount of fruits protein.
