Abstract Erythropalum scandens Bl. is a kind of leafy vegetable which has high edible and medicinal value in Southern China. However, it has been treated as a kind of wild vegetable for a long time and there is still little researches on its yield and quality after fertilization. This study aimed to assess the effect of yield and quality of E. scandens after using two kinds of organic fertilizer: chicken manure and cow manure, which find out the responses of the edible part in E. scandens after using different dosage and proportion of chicken manure and cow manure and find out a best fertilization treatment. We investigated the yield and quality of the edible part in biennial E. scandens including average yield, titratable acid content, sugar acid ratio, crude protein content, ascorbic acid content, tea polyphenols content, nitrate content, general flavone content and macronutrient content (including total nitrogen, phosphorus and potassium) after using different dosage and proportion of chicken manure and cow manure, which to find out a best fertilization treatment via the yield, nutrient and taste. Compared with CK group, proper fertilization can increase the average yield of E. scandens and promote its growth and macronutrient accumulation at the same time. The content of all kinds of nutrients are higher than CK group after using organic fertilizers and they can be accumulated during the process of fertilization. The E. scandens seedlings had the highest yield and best quality under T6 treatment (0.8kg/plant chicken manure+1.2 kg/plant cow manure). However, nitrate can be accumulated in the edible part of E. scandens during the process of fertilization. Compared with CK group, organic fertilization can increase the yield and quality of E. scandens, but excessive fertilization can lead to a significant increase in nitrate levels in plants, even exceeding food safety standards. The nitrate level of E. scandens is a little bit high in this research and better solution is still needed to ensure the quality and food security of E. scandens in the near future.

Moringa Oleifera Lam

Natural biostimulants obtained by plants are intensively used nowadays to improve crop yield and quality. The current study aimed to evaluate the effects of leaf extract of moringa (Moringa oleifera Lam.) (MLE) in modifying baby leaf characteristics of two genotypes of Brassica. The trial was started in October 2020 in a greenhouse; a cultivar of kale ‘Cavolo Laciniato Nero di Toscana’ (CL) and a Sicilian landrace of sprouting broccoli ‘Broccoli Nero’ (BN) were used. The plants, after 15, 30 and 40 days from sowing, were treated with MLE, while the control plants (C) with distilled water. Treatment with MLE modified morphological and nutritional value, but with different behavior in the two genotypes. In fact, in BN the treatment reduced the antioxidant activity (2.2-diphenyl-1-picrylhydrazyl (DPPH)) by 54%, while in CL the treatment increased this parameter by 40%. For the phenolic concentration and the sugar content the values recorded were significantly increased by MLE compared to control plants in CL, where in BN a significant reduction was registered. The CL plants treated with MLE showed a significant reduction (−70%) in nitrate content compared to the control plants; a negative effect was, instead, observed in BN, where the plants treated with moringa showed an increase of 60%. Results of this study showed how the foliar application of MLE was effective in improving various nutraceutical parameters, in particular in kale, because it appears to be a species-specific response.

Effect of organic (biogrcen) and inorganic fetilizers (ammonium sulphate and SP36) on the yield and quality of the temanggung tobacco in andosol soil was studied at Galapansari - Temanggung, from Februai to December 2001. The organic and inorganic fetilizers were formulated in 10 packages, namely : (1) 570 kg ammonium sulphate (AS) ♦ 100 kg SP36; (2) the recommended rate for temanggung tobacco (20 000 kg stable manure 500 kg AS + 100 kg SP36; (3) 5 000 kg organic fetilizer (OF); (4) 7 500 kg OF; (5) 8 500 kg OF; (6) 10 000 kg OF; (7) 12 500 kg OF; (8) 14 500 kg OF; (9) 7 500 kg OF + 3 500 kg sUble manure (SM); (10) 7 500 kg OF + 4 500 kg SM. All the rates of fetilizers were based on one hectare planted area (16 500 plants) The expeiment was designed as a randomized block in four replicates. Results showed that organic fertilizer waa more effective than stable manure in improving die growth, yield and quality of temanggung tobacco. A the rate of 5 000 kg was sufficient to produce high ( 6 313 kg fresh or 800 kg sliced died leaves), grade index (51.68) and crop index (55.31).

Cultivated Potatoes

In the years 1995–1997 the effect of ecological growing on the yield and selected parameters of quality of consumer potatoes (in comparison with conventional way) were investigated. The ecological way of growing differed in the lack of chemical protection against diseases and pests and industrial fertilizers. Field trials were realised with seven varieties (Impala, Karin, Agria, Korela, Rosella, Santé and Ornella) on two sites (Uhříněves and Valečov). The ecological way of growing had markedly negative effect on the yield (decrease by 36%). In qualitative parameters the ecological way increased inconclusively polyphenol content (by 10.2%), decreased inconclusively nitrate content (by 11.0%) and reducing sugars (by 22%). It did not affect dry matter content, resistance of tubers to mechanical damage, table value and glycoalkaloid content. Variety Santé achieved the best results from the point of view of the yield and majority of qualitative parameters among varieties. Qualitative parameters of ecologically cultivated potatoes were significantly affected by the year of cultivation.

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;

ABSTRACT The results of two years (2010-2011) of field studies using two types of nonwoven mulches (one biodegradable, polylactic acid PLA 54 g m-2, and traditional polypropylene PP 50 g m-2) on the yield and quality of tomato are presented. Seeds of tomato (‘Mundi’ F1) were sown in a greenhouse, in containers filled with perlite and sand, and then the plants at the cotyledon stage were replanted in multipot trays filled with substrate for vegetable plants. In the last week of May, seedlings were planted on mulches in the field at a spacing of 50 × 100 cm. The mulch was maintained throughout the growing season. A plot that remained unmulched served as the control. Tomatoes were harvested once a week. The fruits were evaluated for L-ascorbic acid, dry matter, soluble sugars and nitrate content. In 2011, the analysis of the plant material showed that the concentration of L-ascorbic acid was about 23% higher in the tomato fruits harvested from plants grown on biodegradable PLA 61 g m-2 mulch in comparison to the control. A similar effect was demonstrated for the soluble sugar concentration in 2011 for both types of nonwovens.
