“…It shows that by reducing the amount of water available to plant for drought stress, the metabolism of the culture is affected. The irrigation level for a higher average height "Biquinho" pepper is 100% WR in this study; it is similar to that achieved by Aragão et al (2011), who studied different irrigation levels of Magali R. They observed a higher average height, using up to 100% of Eto. Barcelos et al (2015) submitted that the red sweet pepper nozzle potassium doses reach 3.7 cm height.…”

The amount of water needed to meet the water requirement of crops and use of alternative organic substrates affect the development of the plants' nutrients. The objective of this research is to evaluate the cultivation of pepper (Capsicum chinense) under different organic substrates and irrigation levels with supply water and wastewater. The experiment was conducted in a greenhouse at Campina Grande, Paraíba, Brazil. Biquinho BRS Moema pepper species was used. The experimental design was randomized block in a factorial design of 2 x 5 x 2. Two types of water (water supply and wastewater) and five water levels (L) were used based on the water requirement (WR) of the crop as follows: 100% WR (L5), 80% WR (L4), 60% WR (L3), 40% WR (L2) and 20% WR (L1); and two kinds of substrates (caprine and bovine) were also used, all in three replicates with two plants each. The germination percentage for bovine substrate averaged 44%, while for the caprine substrate, it was 18%. 24% increase in the number of leaves at level 4 was compared with that of level 5, where there was 20% reduction of WR of the plant. The pepper "Biquinho" irrigated with wastewater had better average, making it an alternative for irrigation. For the growth of pepper, it is not suitable to use irrigation values less than 40% of the water requirement for culture, because it influences negatively the development of the culture. For pepper, the ideal irrigation level is 80% of water requirement.

A utilização de resíduos industriais, como o lodo de curtume, em substratos para produção de mudas é uma alternativa para redução de custos de produção, e para destinação dos resíduos industriais. O cultivo de pimentas tem ganhado espaço no mercado brasileiro favorecendo principalmente a agricultura familiar, onde um dos desafios é diminuir o custo de produção. O objetivo do trabalho foi avaliar o efeito de diferentes concentrações de lodo de curtume bovino adicionado ao substrato comercial na germinação, desenvolvimento e qualidade de mudas de pimenta biquinho. O experimento foi conduzido em delineamento de blocos casualizados com 7 tratamentos, sendo dois substratos comerciais: Provaso® (TP) e Bioplant® (TL0); e cinco diferentes proporções de lodo desidratado (10, 30, 50, 70 e 90%) misturados ao substrato Bioplant®. Avaliou-se nesse experimento o percentual de germinação, características de desenvolvimento e Índice de Qualidade de mudas de Dickson (IQD). O potencial germinativo foi maior para os tratamentos com adição de lodo de curtume ao substrato comercial Bioplant®. Os melhores resultados para as características de desenvolvimento das mudas ocorreram com a adição de lodo desidratado ao substrato Bioplant® nos intervalos de 30 a 70% de lodo no substrato. O índice de qualidade de mudas foi maior para a mistura de 30% de lodo de curtume desidratado com Bioplant®.

“…The Penman-Monteith equation depends on two primary components (radiation and advection), which increase or decrease in response to other variables (Boulard & Jemma 1993). Medrano et al (2005) calculated the theoretical transpiration rate using a transpiration model and compared it to the real measurements during cucumber growth cycles, obtaining satisfactory coefficients of determination of 0.88 and 0.97 in the fall and spring, respectively.…”

Different irrigation times result in variable transpiration rates, due to the water availability and its interaction with the evapotranspiration demand. The vapor pressure deficit is an accurate indicator of the atmosfere evaporative capacity and can affect plants because of the movement of water in the soil-plant-atmosphere continuum system. This study aimed to evaluate the plant growth, yield and water-use efficiency of bell peppers under irrigation times (8 a.m. and 2 p.m.) and water replacement levels (60 %, 80 %, 100 %, 120 % and 140 % of the crop water requirement - ETc) based on the evapotranspiration demand. The increase in the irrigation levels could be fit to linear models for the variables number of fruits per plant, mean and total fruit weight per plant, fruit length, and root, stem and total dry weight. Irrigation at 2 p.m. increased the total and mean fruit weight and number of fruits per plant, as well as fruit length, if compared to the irrigation at 8 a.m., besides increasing the yield by 50.82 % (2,343.0 g plant-1 to 3,533.6 g plant-1) and the water-use efficiency by 55.64 %. In areas subjected to water shortages, establishing irrigation times based on irrigation management practices can increase the water-use efficiency and yield for bell peppers.
