Última Crop coefficient and water consumption of eggplant in no-tillage system and conventional soil preparation REA Carvalho,Daniel F. de; Lima,Marcio E. de; Oliveira,Alexsandra D. de; Rocha,Hermes S. da; Guerra,José G. M.. Under organic management in Seropédica-RJ, Brazil, using a weighing lysimeter, the crop coefficients (kc), the maximum evapotranspiration and the productivity of eggplant cultivation under two cropping systems (no tillage with straw plus soil with conventional preparation) were determined. A whole randomized layout with two treatments (no tillage and conventional) and five replicates during 134 days of cultivation were adopted. There were no significant differences in the eggplant cultivation in the two cropping systems, with a maximum commercial productivity obtained from 47.42 Mg ha-1 for the no-tillage system, and 47.91 Mg ha-1 for the conventional tillage. The accumulated ETc was 285.15 and 323.44 mm for the no-tillage and conventional, respectively....

The class A pan coefficient (Kp) has been used to convert pan evaporation (ECA) to grass-reference evapotranspiration (ETo), an important component in water management of irrigated crops. There are several methods to determine Kp values, using wind speed, relative humidity and fetch length and conditions. This paper analyses the following methods to estimate Kp values: Doorenbos & Pruitt (1977); Cuenca (1989); Snyder (1992); Pereira et al. (1995); Raghuwanshi & Wallender (1998); and FAO/56 (Allen et al., 1998). The estimated values of Kp and the observed Kp, obtained from the relationship between ETo measured in a weighing lysimeter and ECA measured in a class A pan, were compared by regression analysis. The same routine was adopted to... Tipo: Info:eu-repo/semantics/article Palavras-chave: Pan coefficient; Irrigation scheduling; Weighing lysimeter.

P. de; Sousa,Elias F. de; Pereira,Vinícius R.; Ferreira,Fernando H. A.; Carvalho,Daniel F. de. ABSTRACT This study was carried out to determine the evapotranspiration (ETc) and crop coefficients (Kc) for four stages of “Caatingueiro” corn under the climate condition of Seropédica, RJ, Brazil, using weighing lysimeters. The field trial occurred in 2015, from March 18 to June 25, in two areas cultivated with “Caatingueiro’ corn intercropped with jack bean and in monoculture. The reference evapotranspiration (ETo) was estimated by the FAO-56 Penman-Monteith model and the Kc values were determined by the ratio between ETc and ETo. The Kc values obtained for the intercropping and monoculture systems, were respectively: 0.78 (I); 1.01 (II); 1.10 (III) and 1.01 (IV), and 0.62 (I); 0.92 (II); 1.27 (III) and 0.81 (IV), and they were different from the values...
