Os tratamentos foram compostos de quatro lâminas de irrigação: L1 = 80; L2 = 100; L3 = 110; L4 = 120% da evapotranspiração da cultura (ETc) e quatro doses de potássio: K1 = 80; K2 = 100; K3 = 150 e K4 = 200 kg ha-1 de K2O, totalizando 16 tratamentos, com 3 plantas efetivas por parcela. O delineamento estatístico adotado foi o inteiramente casualizado em parcela subdividida, com 4 repetições, sendo os tratamentos arranjados em esquema fatorial 4 x 4, num total de 64 parcelas experimentais. Foram avaliados a altura e diâmetro do colo da planta, peso médio do fruto, comprimento e diâmetro do fruto e produtividade. Fixando-se a dose de 150 kg ha-1 de K2O. O peso médio máximo alcançado foi de 106,69 g para lâmina de 100,48% da evapotranspiração da cultura. Para um rendimento máximo do pimentão, recomenda-se aplicar uma lâmina de 100% da evapotranspiração da cultura e uma dose de potássio de 80 kg ha-1 de K2O.

SWEET PEPPER PRODUCTIVITY UNDER DIFERENT IRRIGATION AND POTASSIUM DOSES IN SEMI-ARID REGION 2 ABSTRACT The objective of this work was to evaluate the effect of irrigation levels and potassium levels in the production of Rubia sweet pepper hybrid. The treatments comprised four irrigation levels: L1 = 80, L2 = 100 L3 = 110, L4 = 120% of crop evapotranspiration (ETc) and four potassium levels: K1 = 80, K2 = 100, K3 = 150 and K4 = 200 kg ha-1 of K2O, performing 16 treatments with three effective plants per plot. The statistical design was completely randomized in split plot with four replications, with treatments arranged in a 4 x 4 factorial, with a total of 64 experimental plots. We evaluated the height and diameter of the plant, average fruit weight, length and diameter, and productivity. The dose was set at 150 kg ha-1 K2O. The maximum average weight reached was 106.69g for 100.48% of the crop evapotranspiration. For maximum yield of peppers, it is recommended to apply a depth of 100% of crop evapotranspiration and potassium dose of 80 kg ha-1 of K2O.

Salinity is one of the major issues that lead to a reduction in crop productivity. This study aimed to investigate the response of sweet pepper (Capsicum annuum L.) to saline soil. The research was conducted in Agricultural Research Field at Noakhali Science and Technology University during 2018-19 with two sweet pepper varieties as treatment named Red Army (V1) and California Wonder (V2). The results indicated that there were significant variations between the two varieties in different parameters of growth as well as yield performance. The result showed that between the treatments V2 (California Wonder) gave the higher yield ie., 10.65 ton/ha while V1(Red Army) produced 9.61 ton/ha. Moreover, the taller plants and longer fruit were obtained from the V2 which were 32.43 cm and 8.23 cm respectively. Even among the other parameters, V2 gave higher growth and development than V1. Furthermore, average single fruit weight/plant was recorded 76.33 g in California Wonder (V2) whereas Red Army (V1) provided 74.16 g. The finding of the experiment indicated that the overall better performance could be obtained from V2 California Wonder variety of sweet pepper. This study evaluated the varietal performance of two varieties and it can be said from the experiment that the California Wonder is the best variety for cultivation in saline region in Bangladesh.

Experiments using an artificial windbreak and polyethylene mulch were conducted in 1983 and 1984 with sweet pepper in Ste-Anne de Bellevue, Quebec. When analyses were conducted on pooled distance data plant fresh weight was increased by sheltering but not by mulching. In 1983, the windbreak increased yields up to a distance 24 times the windbreak height but only if plants were not mulched. Yield increases were due to greater fruit number per plant rather than a greater mean fruit weight. The windbreak had no influence on yield in 1984. Mulching resulted in a significant increase in yield in both years and appeared to be a more reliable practice than the use of windbreaks to increase pepper yields.Key words: Windbreak, paraweb, pepper, Capsicum annuum L.

Capsicum Annuum L

Sweet pepper (Capsicum annuum L.) is one of the most important vegetable crops in the world because of the nutritional value of its fruits and its economic importance. Calcium (Ca) improves the quality of sweet pepper fruits, and the application of calcite nanoparticles in agricultural practice has a positive effect on the morphological, physiological, and physicochemical properties of the whole plant. The objectives of this study were to investigate the effect of commercial calcite nanoparticles on yield, chemical, physical, morphological, and multispectral properties of sweet pepper fruits using a combination of conventional and novel image-based nondestructive methods of fruit quality analysis. In the field trial, two sweet pepper cultivars, i.e., Šorokšari and Kurtovska kapija, were treated with commercial calcite nanoparticles (at a concentration of 3% and 5%, calcite-based foliar fertilizer (positive control), and water (negative control) three times during vegetation). Sweet pepper fruits were harvested at the time of technological and physiological maturity. Significant differences were observed between pepper cultivars as well as between harvests times. In general, application of calcite nanoparticles reduced yield and increased fruit firmness. However, different effects of calcite nanoparticles were observed on almost all properties depending on the cultivar. In Šorokšari, calcite nanoparticles and calcite-based foliar fertilizers significantly increased N, P, K, Mg, Fe, Zn, Mn, and Cu at technological maturity, as well as P, Ca, Mg, Fe, Zn, Mn, Cu, and N at physiological maturity. However, in Kurtovska kapija, the treatments increased only Ca at technological maturity and only P at physiological maturity. The effect of treatments on fruit morphological properties was observed only at the second harvest. In Šorokšari, calcite nanoparticles (3% and 5%) increased the fruit length, minimal circle area, and minimal circle radius, and it decreased the fruit width and convex hull compared to the positive and negative controls, respectively. In Kurtovska kapija, calcite nanoparticles increased the fruit width and convex hull compared to the controls. At physiological maturity, lower anthocyanin and chlorophyll indices were found in Kurtovska kapija in both treatments with calcite nanoparticles, while in Šorokšari, the opposite effects were observed.

Pepper Fruit

During the ripening of sweet pepper (Capsicum annuum L.) fruits, in a genetically controlled scenario, enormous metabolic changes occur that affect the physiology of most cell compartments. Peroxisomal catalase gene expression decreases after pepper fruit ripening, while the enzyme is also susceptible to undergo post-translational modifications (nitration, S-nitrosation, and oxidation) promoted by reactive oxygen and nitrogen species (ROS/RNS). Unlike most plant catalases, the pepper fruit enzyme acts as a homodimer, with an atypical native molecular mass of 125 to 135 kDa and an isoelectric point of 7.4, which is higher than that of most plant catalases. These data suggest that ROS/RNS could be essential to modulate the role of catalase in maintaining basic cellular peroxisomal functions during pepper fruit ripening when nitro-oxidative stress occurs. Using catalase from bovine liver as a model and biotin-switch labeling, in-gel trypsin digestion, and nanoliquid chromatography coupled with mass spectrometry, it was found that Cys377 from the bovine enzyme could potentially undergo S-nitrosation. To our knowledge, this is the first report of a cysteine residue from catalase that can be post-translationally modified by S-nitrosation, which makes it especially important to find the target points where the enzyme can be modulated under either physiological or adverse conditions.
