“…Studies on fertilization in castor crops were resumed recently in tropical conditions (Oliveira et al, 2010;Moro et al, 2011;Diniz Neto et al, 2012;Ferreira et al, 2014) due to the importance of the crop in the production of biofuel. However, they are still scarce and contemplate few genotypes commonly used by producers, besides being recommended mostly for the northeast region of Brazil (Lisboa et al, 2018).…”

This study was to evaluate the nutrition and the agronomic part of bean intercropped with castor crops submitted to sources and levels of B in the Anápolis-GO, Brazil. The treatments consisted of two sources of B (borax = 11% B and boric acid = 17% B) combined with five levels of B (0.0, 0.5, 1.0, 2.0 and 4.0 kg ha -1 in soil) in bean intercropped with castor, plus monoculture, using 1.0 kg ha -1 B. That leaf levels of B and S in beans, and of B, N, Ca, Mg and Fe in castor were influenced by the sources and levels of B in the intercropping. The bean yield intercropped with castor was not influenced by borated fertilization, neither by the interaction of factors. The highest yield of castor intercropped with beans, 2.040 kg of grains ha -1 , was obtained with the 1.9 kg ha -1 of B, regardless of the source used.

Intercropping of castor bean and sugarcane under irrigation: part 2: yield and agronomic indices

et al. 2019

Intercropping can be an alternative to maximize yields of castor bean and sugarcane. This work aimed to investigate the yields and agronomic indices of castor bean and sugarcane in intercropping system. The experiment was carried out in the field, at the Ponta da Serra Farm, in the municipality of Queimadas-PB, Brazil. Treatments resulted from a 4 x 4 factorial arrangement, with twelve replicates. The irrigation depths (drip system) tested were: 50, 75, 100 and 125% crop evapotranspiration, and the spacings used for castor bean were: (1 x 0.5 m), (1 x 1 m), (1 x 1.5 m) and (1 x 2 m), that is, 20,000, 10,000, 6,666 and 5,000 plants per hectare, respectively, with total area of 2,880 m², each one with twelve plots of castor bean spacing. The following variables were evaluated: land equivalent ratio and relative crowding coefficient. For all irrigation depths tested, sugarcane yield increased linearly with the increment in castor bean spacing. The highest value of land equivalent ratio was found at 1 x 0.5 m spacing, and the lowest values of relative crowding coefficient for sugarcane occurred at 1x 0.5 m spacing for all irrigation depths.
