“…Regardless of the gel use, the levels obtained in this study were higher than appropriate -35 g kg -1 , according to Moreira et al (2010)and similar to those obtained in the long pepper by Wadt et al (2011) -33 to 51 g kg -1 . The chlorophyll content did not differ significantly with the gel use, ranging from 57-58 SPAD units, but the values were higher than those obtained with the Malagueta pepper by Pagliarini et al (2012). The yellow lantern chili productivity received no significant effect from the hydroretentor gel application.…”

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

“…The increase of leaf area promotes an increase in the plant's ability to take advantage of solar energy aiming photosynthesis and, then it can be used as a parameter related to productivity (Gonzalez-Sanpedro et al, 2008). Pagliarini et al (2012) state that pepper plants showing higher heights are able to sustain a larger number of leaves, without damage on the structure, avoiding, for example, seedling damping-off. Moreover, these leaves may show higher leaf area, which enables luminous incidence, accelerating the photosynthetic processes essential to the plant development.…”

Harvest seasons and pruning management in pepper: production and pungency of the fruits

et al. 2017

Changes in plant architecture, such as apical pruning and harvesting at the right time, are management practices to obtain not only greater fruit production, but mainly quality and pungent fruits, preferred by the consumer market. We evaluated the effect of management of pruning and harvest seasons on growth, production and pungency of fruits conducted in the field. Nine seasons of harvest were studied {90, 101, 116, 131, 146, 161, 176, 191, 206 and 221 days after transplanting (DAT)} and two management systems (pruning and no pruning). The treatments were arranged in a factorial design (9x2) with split plot in a randomized block design with three replications. The agronomic traits analyzed were: height, chlorophyll, leaf area, soluble solids, number of fruits and pepper yield. The content of capsaicin and dihydrocapsaicin was determined using fruits harvested in two seasons (146 and 161 DAT) and in management systems (pruning and no pruning), in a factorial scheme (2x2), in a randomized complete block design with five replications. Growth and production traits did not differ significantly for pruning and no pruning managements, with an average of 71.8 fruits/plant and productivity of 429.7 g/plant. The agronomic traits were adjusted to the quadratic model. The maximum yield (529.09 g/plant) and the maximum number of fruits per plant (95.34) were estimated at 164.83 and 163.21 DAT, respectively. The use of pruning resulted in fruits with a higher content of capsaicin (363.89 mg/kg) and dihydrocapsaicin (198.27 mg/kg) at 161 DAT. Pruning management results in more pungent and better quality fruits for industry, and the maximum production of BRS Mari pepper was estimated at 164.83 DAT, important information for pepper producers, in order to schedule the harvests.

“…Essa relação é atribuída, principalmente, ao fato de que 50 a 70% do N total das folhas é integrante de enzimas (Chapman & Barreto, 1997) que estão associadas aos cloroplastos (Wood et al, 1993). Pagliarini et al (2012), trabalhando com mudas de pimenta malagueta em função de doses de fertilizantes obtiveram Rev. Ceres, Viçosa, v. 63, n.5, p. 698-705, set/out, 2016 resultados positivos com o incremento do fornecimento de nutrientes às plantas.…”

“…O cultivar Liso de Calcutá apresentou a menor MSR na solução 100% (34 mg, para cinco mudas) (Figura 3C). Esses resultados mostram que o substrato fibra de coco, irrigado apenas com água, não forneceu nutrientes suficientes para atender a exigência das mudas e assemelham-se aos obtidos por Pagliarini et al (2012), que avaliaram mudas de pimenta malagueta fertirrigadas. Efeito positivo da fertirrigação sobre a produção de biomassa de mudas de beterraba, pepino japonês e melancia são relatados por Guimarães et al (2002), Cañizares et al (2002) e Ramos et al (2012).…”

Production of gherkin seedlings in coconut fiber fertirrigated with different nutrient solutions

et al. 2016

View full text Add to dashboard Cite

Seedling quality is a key factor to achieve success in vegetable production. The present work aimed to evaluate the production of gherkin seedlings in substrate of coconut fiber fertirrigated with different concentrations of nutrients. The experimental design was completely randomized in a 3 × 5 factorial with four replications. The treatments consisted of combinations of three cultivars of gherkin (Do Norte, Liso de Calcutá, e Liso Gibão) with five concentrations of nutrients in the solution (0, 25, 50, 75, and 100%). The nutrient solution, considered standard, matches the recommended solution for melon in hydroponic systems. We evaluated the variables: chlorophyll index, shoot length, number of leaves, stem diameter, main root length, dry weight of leaves, roots, and stem, mass of total dry matter, leaf area, specific leaf area, and leaf area ratio. All variables were affected by the ionic concentration in nutrient solutions. The use of coconut fiber in the production of gherkin seedlings is more efficient with nutrient solutions in concentrations ranging from 75 to 100% of the recommended solution for melon cultivation.
