Abstract: Appropriate management techniques, such as fertilization programs and the use of technology in the production process, have been employed to meet the demand for vegetables year-round. Because vegetables require a considerable amount of water for their development, hydrogels can guarantee the supply of water in regions with water deficits. The aim of this study was to evaluate the use of hydrogel and nitrogen fertilizer on the development and productivity of arugula cv. Cultivada in two successive crops. The ex… Show more

Water is an essential resource in agriculture, and its efficient use is fundamental to ensuring the sustainability of the sector. The use of more rational and sustainable technologies is an important strategy for optimizing the use of water in agriculture. In view of the above, the aim of this study was to evaluate the effect of different irrigation depths on both chemical and physical variables of melon fruits, and yield, in plants grown with or without hydrogel application. The experiment was conducted in a randomized block design with ten treatments and four blocks. The treatments were arranged in a 5 × 2 factorial scheme, referring to five irrigation depths (50, 75, 100, 125, and 150% of crop evapotranspiration - ETc), and with or without hydrogel application (4 g L-1). The irrigation system used was drip irrigation. Irrigation depths positively influenced the variables evaluated, with the highest yield (39,075.69 kg ha-1) obtained with the highest water depth of 394 mm (150% ETc), while the use of hydrogel reduced the internal cavity of the fruit. The fruit physical characteristics (pulp thickness and internal cavity) showed positive linear increments within the interval of irrigation depth evaluated. Fruit electrical conductivity showed a linear decrease as the irrigation depths increased, while the pH was described by a quadratic polynomial equation. The use of hydrogel was not enough to mitigate the negative effects of deficit irrigation. However, the increase in irrigation depths improved the quality and yield of melon fruit.

Rocket plants in response to nitrogen concentration in nutrient solution

et al. 2021

View full text Add to dashboard Cite

Nitrogen (N) is the second most accumulated nutrient in rocket. This nutrient greatly affects growth, productivity and quality of the vegetable. Rocket is the second most widely grown leafy vegetable in hydroponic system; however, no studies on how N concentration in nutrient solution affects this crop can be found in literature. We studied four concentrations (79.2; 118.8; 158.4 and 237.6 mg L-1 of N) in a randomized block design with five replicates. Maximum number of leaves, leaf area, dry mass and productivity of rocket cv. ‘Folha larga’ were obtained with the highest N concentration. The rocket quality, evaluated by the nitrate content, was maximum with 210.2 mg L-1 of N and its value in the concentration which maximized productivity is in the acceptable range for vegetables; so, it is recommended to grow rocket with 237.6 mg L-1 of N in the nutrient solution.

Pepper cultivation is widely accepted by consumers and is responsible for supporting the establishment of family farming by providing employment for manpower. This study aimed to investigate the effects of nitrogen fertilization and hydroretentor gel application on the development and productivity of Capsicum sp. Each experiment applied a 2 x 5 factorial randomized block design, with and without the application of hydroretentor gel (factor A) with five N (factor B) doses (0; 50; 100; 150 and 200 kg ha-1), and four replications. Analysis was made of the foliar nitrogen content, chlorophyll content, plant height, stem diameter, fruit length, fruit diameter, fruit number and weight, and productivity. The application of gel hidroretentor only influenced the culture of chilli pepper in the development and productivity. The nitrogen doses increased the productivity of yellow chilli and favored only the development of chilli pepper
