“…In this context, knowledge of crop sensitivity to stress due to water deficiency is fundamental to reduce impacts on production (MIORINI et al, 2011) and on irrigation costs (ALI et al, 2007). Experiments addressing this theme have shown positive results regarding melon tolerance to stress due to water scarcity (DOGAN et al, 2008;SHARMA et al, 2014).…”

-Local knowledge about irrigation management in yellow melon can promote higher precision to water supply for irrigation purposes, increasing productivity and reducing production costs. The aim of this study was to evaluate the effects of different irrigation depths for yellow melon production and on yield response factor to water (Ky) in the productive phase. The experiment was carried out in Fortaleza, state of Ceará, Brazil, in complete randomized blocks with six treatments, four replicates and six plants per plot. Treatments were applied from intermediate (III) to final (IV) physiological state with water depths equivalents to 25%, 50%, 75%, 100%, 125% and 150% of the crop evapotranspiration (ETc). Ky was calculated according to FAO-33 report methodology in the range from 25% to 100% ETc. The variables analyzed were number of fruits per plant, polar and equatorial diameters, fruit fresh weight, commercial yield, skin and pulp thickness, and soluble solids. Treatments influenced the number of fruits per plant, equatorial diameter, fruit fresh weight, commercial yield, and soluble solids. The best results were reached with commercial yield equal to 32.2 Mg ha -1 , 1.46 fruits per plant, equatorial diameter equal to 16.3 cm, fruit fresh weight equal to 2.3 kg and soluble solids equal to 12 ºBrix with 100.3% ETc in the productive phase. The crop was tolerant to water supply reduction on the productive phase (Ky < 1) through daily irrigation with controlled water deficit. Index terms: Cucumis melo, evapotranspiration, drip irrigation. PRODUÇÃO E FATOR DE RESPOSTA DO MELOEIRO AMARELOA LÂMINAS DE IRRIGAÇÃO NA FASE PRODUTIVA RESUMO -Informações locais sobre manejo hídrico em olerícolas podem oferecer maior precisão ao fornecimento de água pela irrigação, concorrendo para elevar a produtividade e reduzir os custos. Neste trabalho, foram avaliados os efeitos de distintos níveis de irrigação sobre a produção do melão-amarelo e sobre o fator de resposta da cultura frente à irrigação deficitária (Ky). O experimento foi conduzido em Fortaleza, Ceará, utilizando o delineamento em blocos casualizados, com seis tratamentos, quatro repetições e parcelas de seis plantas. Os tratamentos foram diferenciados nas fases fenológicas intermediária (III) e final (IV), com lâminas de água correspondentes a 25%, 50%, 75%, 100%, 125% e 150% da evapotranspiração da cultura (ETc). O Ky foi estimado pela metodologia do Boletim 33 da FAO, no intervalo de 25% a 100% da ETc. Foram analisadas as variáveis número de frutos por planta, diâmetros polar e equatorial, massa fresca do fruto, produtividade comercial, espessuras da casca e da polpa e sólidos solúveis. Os tratamentos influenciaram significativamente sobre o número de frutos por planta, o diâmetro equatorial, a massa fresca do fruto, a produtividade comercial e os sólidos solúveis. As irrigações com 100,3% da ETc na fase produtiva do meloeiro maximizaram a produtividade comercial, estimada em 32,2 Mg ha -1 e proporcionaram 1,46 fruto por planta com diâmetro equatorial de 16,3 cm...

“…Since the difference in soil water availability during the crop cycle was small in both treatments, a similar yield would have been expected. Previous results on common beans have shown that, under stress, the plants have a reduced number of pods (Miorini et al, 2011), less pods per plant (Miorini et al, 2011;Stone et al, 1988), less grains per pod (Carvalho, 2013) and number of pods (Miorini et al, 2011). Also, the plant size was smaller independently of the event of water stress (Miorini et al, 2011).…”

“…Drought can modify leaf development and thus, affect grain yield by reducing the active leaf area for photosynthesis (Guimarães, 1996;Fancelli and Dourado Neto, 1991). Plant height, leaf area index, number of seeds per pod, number of pods per plant and yield are reduced in plants suffering from water stress (Monteiro et al, 2010), although the number of pods per plant was the most sensitive variable to maintain a potential yield (Guimarães et al, 2011;Miorini et al, 2011). Likewise, the bean root system develops mostly in the upper soil layer enhancing the sensitivity of the crop to water stress and reinforcing the role of irrigation water supply for proper crop development during scarce rainfall periods (Carlesso et al, 2007).…”

“…Since crop is sensitive to water stress, irrigation is needed in regions where rainfall is unevenly distributed to maintain yield and farmersí benefits (Didonet, 2005;Guimarães et al, 2011). Farmerís revenue in irrigation areas is about 70% higher than in rain fed crops although under stress conditions, a 20% yield decrease has been reported by Miorini et al (2011) In Brazil, irrigation demands about 72% of the water (Alves, 2015) and water resources are increasingly scarce every year. Considering this scenario, we can expect that water resources will be less available for irrigated agriculture and competition for water will increase in the near future.…”

a b s t r a c tBrazil is one of the top world producers of the staple commodity common bean (Phaseolus vulgaris L.). Irregular distribution of rainfall and the lack of rain during the crop reproductive phases affect its yield and increase the demand of water for irrigation. However, in recent years, water resources have decreased and water saving has become an issue. Thus, soil management techniques, which reduce evaporation, and efficient irrigation programming, through the monitoring of soil water content, could be adopted in water scarcity scenarios. This study assesses the effect of crop residues management (incorporated IR or left on soil surface NR) in soil water availability (and its retention in the soil pore space), and yield in common beans cultivated under no-till and directly seeded in an irrigated farm located southwest of São Paulo state. Soil water content was monitored with TDR probes installed within the 0-20 cm layer and its retention was assessed through the soil water retention curve. For the same irrigation management, the IR led to soil water content was lower than NR but both soil managements had similar available water and their demand of water for irrigation was similar. For the same soil water content, NR soils could hold it tightly in the pore space and the root plant system would require higher energy to absorb it. Then, it is foreseen that the root system in IR soils will be shallower than in NR soils, since it will withdraw water easily within the first 20 cm, however, in NR, the roots will extend deeper searching for available water. Considering 40 kPa as a threshold value, the plants suffered water stress during all crop cycle at the same physiologic stages in both soils. The variables studied to assess yield presented no-statistical significance in the T test at significance level of 0.05.

“…Many researches are mentioned on the effects of hydric restriction applied to different vegetative and reproductive stages, where Such Miorini et al (2011) evaluated the influence of water suppress, in comparison with irrigation in all and none growing stages of common beans (Miorini et al, 2012). In addition, Catuchi et al (2012) evaluated the interference of potassium fertilizing in physiologic parameters of two soybean cultivars, under hydric restriction (Catuchi et al, 2012), as well as Artigiani et al (2012), which aimed to evaluate yield compounds, productivity and industrial quality of rice grains of the cultivar BRS Primavera, in function of the silicon application combined with broadcast nitrogen fertilizing, in dry and irrigated conditions (Artigiani et al, 2012).…”

The hydric resources are primordial for plants growth and development, under conditions where the growing environment express hydric shortage. These conditions can directly or indirectly affect development, the formation of new organs, yield and quality seeds. The study aimed to evaluate the physiological quality of rice and soybean seeds, produced under hydric restriction. Experiment 1: for rice, the scheme was completely randomized with four repetitions, the treats of hydric restrictions were applied in the periods of 0, 24, 48, 72 hours at the phenological stage of filling seeds. Experiment 2: for soybean, the scheme was completely randomized, conducted in factorial scheme, four replicates with four hydric restriction periods of 0, 24, 48 and 72 hours, at the phenological stage of filling seeds. It was verified that as the hydric restriction hours increase, at the rice seeds filling, the physiologic quality is affected, the higher effect occurred at 72 hours of restriction. While at the soybean seeds production it was not verified such effects, only the thousand seeds mass was negatively affected. The physiological quality of rice seeds were more affected, when compared to soybean seeds submitted to the same treats of hydric stress.
