“…The scheduling of irrigation at 1.25×ET c with a 40-cm SSDI recorded a significantly higher seed cotton yield in both 2016 and 2017 (Table 2). Azevedo et al [33] reported that irrigation with 120% of that crop evapotranspiration under sprinkler irrigation produced the maximum seed cotton yield. Moreover, Shruti and Aladakatti [34] determined a significantly higher seed-cotton yield (4024 kg ha -1 ) in drip irrigation at 1.0 × ET c .…”

The purpose of this study was to improve irrigation water use and cotton yield using real-time crop evepotranspiration based on the FAO-56 Penman-Monteith and canopy cover using surface drip and subsurface drip irrigation. The experiments were conducted Southeast Anatolia Region of Turkey, during 2016 and 2017. The experimental design was split-plots in randomized blocks using three replications. The main plots were surface drip irrigation (SDI), subsurface drip irrigation (SSDI-30 cm) and SSDI-40 cm. Sub-plots were three different irrigation levels based on real crop evapotranspiration (ETc), 0.75×ETc, 1.00×ETc and 1.25× ETc. There were significant differences (657 kg ha -1 ) between the seed cotton yield of SDI (3667 kg ha -1 ) and SSDI with a 40-cm lateral depth (4323 kg ha -1 ). Irrigation water and crop consumptive water use were 552 and 589 mm for the SSDI-40 cm recommended treatment, respectively. According to the projection using the results for cotton cultivation area in the study region, SDI and SSDI could save water about 37 and 42% compared to furrow irrigation, respectively. Net income based on unit area in SDI and SSDI was higher 20 and 69% than it in furrow irrigation, respectively. Irrigation scheduling based on real crop evapotranspiration (1.0×ETc) was more appropriate for water saving and increasing water productivity (0.84 kg m -3 ). The use of drip irrigation systems (especially SSDI) is significantly important to improve cotton yield, water use and economic contribution considering possible water shortage, decreasing water resources, farmers conditions, irrigation schemes, regional and national incomes.

CONSUMO HÍDRICO E COEFICIENTE DE CULTIVO DA MAMONEIRA, CULTIVAR BRS ENERGIA JOSÉ MARCELO DIAS1; PEDRO VIEIRA DE AZEVEDO2; JOSÉ RENATO CORTEZ BEZERRA3; NAPOLEÃO ESBERARD DE MACÊDO BELTRÃO3; GERALDO DOS SANTOS OLIVEIRA3 E MARIA IDALINE PESSOA CAVALCANTI4 1Embrapa Produtos e Mercado, marcelo.dias@.embrapa.br,2Centro de Tecnologia e Recursos Naturais – UFCG, pvieira@dca.ufcg.edu.br.3Embrapa Algodão, jose.cortez-bezerra@embrapa.br; geraldo.oliveira@.embrapa.br.4Centro de Ciências Agrárias – UFPB, idalinepessoa@.hotmail.com. 1 Resumo O presente trabalho objetivou a determinação das exigências hídricas da mamoneira cultivada sob irrigação. Os experimentos de campo foram conduzidos na Estação Experimental da Embrapa Algodão, localizada em Barbalha – CE, nos anos de 2005 e 2006. A cultivar utilizada foi a BRS Energia, de ciclo precoce e porte baixo com 107 dias de ciclo, composto de 5 fases fenológicas: I - Germinação até 10% de cobertura do solo; II - Até inflorescência do 1º cacho; III - Até inflorescência do 2º cacho; IV - Maturação do 1º cacho; V - Maturação do 2º cacho, em uma área de 1 hectare. A estimativa da evapotranspiração da cultura (ETc), para as diferentes fases fenológicas, foi obtida pelo método do balanço de energia baseado na razão de Bowen. O coeficiente de cultivo (Kc) foi obtido pela relação entre a evapotranspiração da cultura (ETc) e a evapotranspiração de referência (ETo), estimada pelo método FAO-Penman-Monteith. A evapotranspiração média para os dois anos de cultivo foi de 565,1 mm, com um consumo mínimo de 47,4 mm na fase I e um máximo de 212.3 mm na fase IV. Os valores médios de Kc por fase fenológica foram de 0,74; 0,93; 1,00; 1,18 e 0,92. O Kc pode ser definido em função dos dias após a emergência, pela equação Kc = -0,0001DAE2 + 0,016DAE + 0,556.

P.WATER CONSUMPTION AND CROP COEFFICIENT OF CASTOR BEAN CROP, CV. BRS ENERGIA 2 ABSTRACT The objective of this study was to determine water requirement of castor bean under irrigation. Field experiments were conducted at the Experimental Station of Cotton Embrapa in Barbalha city, Ceará State, Brazil in 2005 and 2006. With early maturity and low height, cv. BRS Energia was used, 107-day cycle, consisting of five phenological phases: I- germination up to 10% soil covering; II- up to inflorescence of the first bunch; III- up to inflorescence of the second bunch; IV- up to maturation of the first bunch; V- up to maturation of the second bunch, in 1 hectare area. The estimate of crop evapotranspiration for the phenological phases throughout the crop cycle was obtained by the Bowen-ratio energy balance. Crop coefficient (Kc) was obtained by the ratio between crop evapotranspiration (Etc) and reference evapotranspiration (ETo), estimated by the FAO-Penmam-Monteith method. The mean evapotranspiration for the 2 year-cultivation period was 565.1 mm, being 47.4 mm minimum consumption in phase 1 and 212.3 mm maximum consumption in phase IV. Mean values of Kc by phenological phase were 0.74; 0.93; 1.00; 1.18 and 0.92. Kc was defined as a function of days after emergence (DAE) by the equation Kc = -0.0001DAE2 + 0.016DAE + 0.556. Keywords: Ricinus communis, evapotranspiration, Bowen ratio.
