Myrciaria dubia (Kunth) McVaugh is a fruit tree native to the Amazon with great potential due to its nutraceutical properties; thus, ex situ adaptation technologies should be developed. The objective of this study was to determine the evapotranspiration (ETc) and crop coefficient (Kc) of Myrciaria dubia for domestication and conservation on uplands. Two Myrciaria dubia plants of 2, 4, and 6 years old with similar morphological characteristics of height, number of branches (basal and terminal), and diameter (stem and canopy) were transplanted into drainage lysimeters. Residue of organic mulching composed of a native grass (Trachypogon plumosus) was applied once to one plant of each age category. The mean ETc values for 2-, 4-, and 6-year-old plants in the presence and absence of mulch were 2- and 2.7-mm∙day-1, 3.2- and 3.9-mm∙day-1, and 6.1- and 7.2-mm∙day-1, respectively. The mean Kc values in the EI, EII, and EIII phenological stages with and without mulch were 0.4 and 0.6, 0.6 and 0.8, and 1.1 and 1.3, respectively. The ETc and Kc values for Myrciaria dubia plants with organic mulching can be used in irrigation planning for cultivation, domestication, conservation, and efficient use of water resources in tropical savannas of Roraima, Brazil. |

The level of diffusion of integrated croplivestock systems (ICLS) and integrated livestockforestry systems (ILFS) among cattle farmers in Brazil is still low, despite the environmental and economic benefits and governmental policy support. The present study aims at identifying the factors that determine the adoption of these systems in the State of São Paulo, Brazil. The theory of adoption and diffusion of agricultural innovations takes into consideration several economic and non-economic determinants. Data from 175 farms and multinomial logit models were used to test hypotheses on the role played by farms?scale, farms? topography, farms? type of soil, farmers? knowledge, farmers? capacity for innovation, availability of local facilities for grain trade, extension service, and credit supply. The results highlighted the important role played by farmers? human and physical resources when adopting these systems. Knowledge, scalable agricultural land and fixed capital for crop farming being the most relevant ones. Access to credit and extension service helped to overcome lack of physical capital and knowledge. Farmers with innovative capacity were the ones who showed to be more prone to adopt. Availability of local infrastructure for grain trading facilitated the adoption of ICLS. Adoption of ILFS turn out to be an alternative option in slopping land and sandy soils. Results shed light on strategies to accelerate the diffusion of those systems. |
