“…Cabello et al (2009) observed a reduction of 15% in melon yield when the nitrogen doses were excessive (390 kg of N ha -1 ). According to Ruiz & Romero (1999), the reduction in the commercial yield is associated with the reduction of the nitrate reductase enzyme in the leaves and, consequently, a reduction in the exportation of amino acids to the fruits.…”

A B S T R A C TThe objective of the present study was to evaluate the response of eggplant, cv. 'Ciça' , with respect to yield, number of fruits and dry matter (root and stem), when grown in a greenhouse and conducted under fertigation with nitrogen and potassium. Resposta da cultura da berinjela fertirrigada com doses de nitrogênio e potássio R E S U M O Objetivou-se, no presente estudo, avaliar a resposta da cultura da berinjela, cultivar Ciça, com relação à produtividade, número de frutos e massa seca (raiz e caule), quando cultivada em ambiente protegido e conduzida sob fertirrigação com nitrogênio e potássio. O experimento foi conduzido no Centro Técnico de Irrigação da Universidade Estadual de Maringá, entre os meses de fevereiro e agosto de 2015. Foram testadas quatro doses de nitrogênio (0,0; 6,43; 12,86 e 25,72 g de N planta -1 ) e quatro doses de potássio (0,0; 5,18; 10,36 e 20,73 g de K planta -1 ), perfazendo 16 tratamentos em esquema fatorial 4 x 4, dispostos em delineamento inteiramente casualizado com quatro repetições, em Latossolo vermelho distrófico, de textura arenosa. O maior número de frutos por planta e produtividade foi obtido na dose entre 14-17 g de N planta -1 (145-177 kg ha -1 ). Doses isoladas de potássio não influenciaram estatisticamente a produtividade nem a massa seca de raiz.

“…OLIVEIRA et al, (2011);CARVALHO et al, (2011);SANTANA et al, (2009);and DOGAN (2008) reported production losses due to excessive application of irrigation water. On the other hand CABELLO et al, (2009) applying 125 and 140% of the ETC found that the treatments did not significantly affect the melon production.…”

“…CABELLO et al, (2009) studied the effect of water stress on the yield of melons cv. Sancho, under field conditions, they found that a deficit of 25% of the crop evapo-transpiration (ETC) did not affect significantly the production; however, water deficit of 40% of ETC resulted in a production decrease of 22% compared with the treatment without water deficit.…”

“…Some surveys have shown that the melon is sensitive to drought with reduced production and size of the fruit if grown with water restriction (DANTAS et al, 2011;ZENG et al, 2009;CABELLO et al, 2009;LI et al, 2012). Moreover, water excess in the soil may result to reduced productivity, and quality problems on fruits in different cultures (CABELLO et al, 2009;OLIVEIRA et al, 2011;CARVALHO et al, 2011;SANTANA et al, 2009;DOGAN et al, 2008).…”

ABSTRACT:The study aimed to evaluate the "Gália" melons productive characteristics grown in greenhouse under different irrigation levels, and conducted with and without soil cover by plastic mulching. Experiments I (WC) and II (WtC) were conducted simultaneously in a protected environment, using a completely randomized design (CRD), where plants of Gália melons (Hybrid Nectar cv.) received five levels of water depth defined by 50, 75, 100, 125 and 150% of evapotranspiration (water requirement), with four replications, differing only by utilization (WC) or not (WtC) of plastic mulching. The results showed that the variables productivity, average weight, length and diameter of the fruits were affected by different levels of water replacement in the soil regardless the use or not of the soil cover. The largest reductions in productivity 46.32 and 32.03% were observed for the treatment of 50%, compared to the treatment of 100% for experiments I (WtC) and II (WC), respectively.

Agricultural practices to improve yields in small‐scale farms in Africa usually focus on improving growing conditions for the crops by applying fertilizers, irrigation, and/or pesticides. This may, however, have limited effect on yield if the availability of effective pollinators is too low. In this study, we established an experiment to test whether soil fertility, soil moisture, and/or pollination was limiting watermelon (Citrullus lanatus) yields in Northern Tanzania. We subjected the experimental field to common farming practices while we treated selected plants with extrafertilizer applications, increased irrigation and/or extra pollination in a three‐way factorial experiment. One week before harvest, we assessed yield from each plant, quantified as the number of mature fruits and their weights. We also assessed fruit shape since this may affect the market price. For the first fruit ripening on each plant, we also assessed sugar content (brix) and flesh color as measures of fruit quality for human consumption. Extra pollination significantly increased the probability of a plant producing a second fruit of a size the farmer could sell at the market, and also the fruit sugar content, whereas additional fertilizer applications or increased irrigation did not improve yields. In addition, we did not find significant effects of increased fertilizer or watering on fruit sugar, weight, or color. We concluded that, insufficient pollination is limiting watermelon yields in our experiment and we suggest that this may be a common situation in sub‐Saharan Africa. It is therefore critically important that small‐scale farmers understand the role of pollinators and understand their importance for agricultural production. Agricultural policies to improve yields in developing countries should therefore also include measures to improve pollination services by giving education and advisory services to farmers on how to develop pollinator‐friendly habitats in agricultural landscapes.
