“…The results obtained corroborate those reported by Rodrigues et al (2014), where for MFI and MSI, there was formation of positive linear models as a function of the N doses applied in a soil cultivation system. Other studies show the beneficial effect of N fertilization on the production of melancholy fruits (Barros et al, 2012), paprika (Santos et al, 2020) and Chamomile (Roza et al, 2016).…”

Jambu is a vegetable, widely consumed in the Brazilian North Region, both in typical foods and medicinal herb. Despite its versatility, there are uncountable challenges in relation to its cultivation, especially with regard to the availability of information on nutritional management, such as the lack of data on the effect of liming associated with the supply of nitrogen (N) on the production performance of the crop. Thus, the effect of nitrogen fertilization and liming on growth, production, physiological responses and post-harvest quality of the yellow-flowered variety jambu was evaluated. The experimental design was randomized in factorial blocks (6 x 2), with five repetitions. The treatments consisted in the combination of six doses of N (0; 60; 90; 120; 150 and 180 kg ha-1) with and without liming application (0 and 70% V). The variables of growth, production, gas exchange and post-harvest quality of jambu were evaluated. Standardly, there was interaction between N-dose and liming factors for most of the analyzed variables, except for titratable acidity and total soluble solids and titratable acidity ratio. In general, the increasing of N doses combined with liming positively affected growth, production, physiological responses and post-harvest quality, and it was observed that in the 170 kg ha-1 dose of N higher response was obtained in the biomass accumulation of the aerial part and in the 180 kg ha-1 dose of N maximum production of inflorescences. Therefore, the use of correctives associated with nitrogen fertilization is recommended to obtain more significant production and quality of jambu.

“…Bell pepper (Capsicum annuum L.) is one of the most consumed vegetables in Brazil, and its production has been increasing in recent years, due to its better adaptation to protected environments compared to other crops, making the country one of the largest producers in the world, standing out as a vegetable of great economic importance in the national market (SANTOS et al, 2020;SILVA et al, 2020a). According to the Anuário Brasileiro de Horti & Fruti, the estimated production of peppers in Brazil in 2019 was 350 thousand tons with a harvested area of 13 thousand hectares.…”

Exogenous application of salicylic acid on the mitigation of salt stress in Capsicum annuum L.

Salinity has limited conventional vegetable cultivation, especially in semi-arid regions. In this regard, the use of elicitors that act to induce tolerance to salt stress, such as salicylic acid, has emerged as a promising alternative. This study evaluated the effects of foliar spraying with salicylic acid on the mitigation of salt stress on the morphophysiology and production of bell pepper cv. All Big. The study was conducted in a greenhouse in Campina Grande - PB, Brazil, adopting a completely randomized design, in a 4 x 4 factorial arrangement, corresponding to four levels of electrical conductivity of irrigation water (0.8; 1.6; 2.4; and 3.2 dS m-1) and four concentrations of salicylic acid (0; 1.2; 2.4 and 3.6 mM), with three replicates. The foliar application of salicylic acid at a concentration of 1.6 mM attenuated the effects of salt stress in gas exchange, growth, mean fruit weight, and total production per plant, and decreased the percentage of intercellular electrolyte leakage of sweet pepper cv. All Big plants, at 80 days after sowing.

Bell pepper germination and seedling’s parameters under different osmotic potentials

et al. 2022

Bell pepper (Capsicum annuum L.) is the third most cultivated Solanaceae species in Brazil and is highly sensitive to osmotic stresses. The increasing soil salinity is a frequent problem that hinders the plant absorption of water and nutrients by the roots, limiting agricultural production. Therefore, this study’s objectives were to evaluate the germination, vigor, and development of bell pepper commercial cultivars after NaCl treatments to simulate osmotic stress. Five cultivars (Yolo wonder, SF134 yellow, Marta, All big red, Cascadura) were submitted to four osmotic potentials (salt stresses of 0, -0.3, -0.6, -0.9 MPa) in a factorial scheme of 5×4, with four repetitions. The results indicated that the bell pepper germination is highly affected according to the presence of NaCl. The bell pepper germination supports NaCl concentrations equal to or higher than -0.3 MPa osmotic potential. Significant reductions in germination, germination speed index, seedling length, and dry mass as the salinity increases - osmotic potential decrease. The yellow bell pepper ‘SF134’ presented similar germination down to -0.6 MPa and can be cultivated in regions with salinity problems. The green bell pepper ‘Cascadura’ presented great germination, germination speed index and dry mass, and superior seedling length, being indicated for cultivation in more diverse environments.
