“…The comparison between systems focuses mainly on their efficiency compared to monocultures (ALBUQUERQUE et al, 2012). The area equivalence index (AEI) indicates the sum of the areas required to be cultivated in monoculture with both crops in order to achieve a yield of 1.0 ha of the intercropping system; the higher the index, the more advantageous the system (SANTOS et al, 2016;ARENAS-CORRALIZA et al, 2018).…”

The objective of this work was to evaluate the potential of agroforestry systems in the semiarid, and to evaluate the productivity of eucalyptus in three planting spacing, in single cultivation in agroforestry systems. The comparison of the systems was in a randomized block design with four systems (monoculture; peanut systems; castor bean; cassava) and three eucalyptus spacing (10 m x 2 m, 10 m x 3 m and 10 m x 4 m). Monocultures and other characteristics were compared by randomized block design. Peanut productivity was evaluated at three and a half months, castor productivity at five and eight months and cassava productivity at 21 months. Eucalyptus productivity was measured at 13 and 21 months of age. The results showed that the wood production was greater in the 10 m x 2 m spacing and in the system with castor and single cultivation. The castor yield was higher in the system, in the 10 m x 3 m spacing, while the cassava productivity was higher in monoculture. The area equivalence index of the systems was higher than that of monocultures. Therefore, eucalyptus agroforestry systems intercropped with castor and cassava are suitable for the semiarid region. The 10 m x 2 m spacing provided a larger volume of wood (m³ ha-1). Castor yield was higher in the 10 m x 3 m spacing. For cassava, the highest yield was obtained in monoculture and in the system with 10 m x 3 m or 10 m x 4 m spacing.

“…This methodology has been used satisfactorily by breeding programs in the selection of superior genotypes in perennial crops, such as cashew (MAIA et al, 2009), eucalyptus (ROSADO et al, 2012) and annuals, rice (REGITANO et al, 2013), cowpea (TORRES et al, 2016SANTOS et al, 2016;CARVALHO et al, 2017, TORRES FILHO et al al., 2017 in several regions.…”

Combined selection for adaptability, genotypic stability and cowpea yield from mixed models

et al. 2021

The potential expression of crop productivity is a constant challenge for plant breeders in the face of oscillations in environmental variables, making selection difficult and increasing the operational and methodological costs in obtaining the ideal cultivar for a determined region. The objective of the research was to investigate the effects of genotype x environment interaction in the selection of cowpea lines with high grain yield, adaptability, and genotypic stability simultaneously, in environments of the Northwest region of Rio de Janeiro State, using mixed models (Maximum Restricted Likelihood - REML/Best Linear Unbiased Prediction - BLUP). 27 cowpea genotypes were evaluated in six environments by combining location (Cambuci-RJ and Bom Jesus do Itabapoana-RJ) and year (2016, 2017 and 2018). A randomized block design with four replications was performed. The genetic parameters were estimated via the REML/BLUP procedure, and the selection was based on the harmonic mean method of the relative performance of the genetic values (HMRPGV). A meaningful difference was observed for environment and genotype x environment interaction. The residual variance and the variance of the genotype x environment interaction formed the most significant fractions of the phenotypic variance. Lines 4 (Bico-de-ouro 1-5-24), 6 (Pingo-de-Ouro 1-5-4), 5 (Pingo-de-Ouro 1-5-26), and 9 (Pingo-de-Ouro 1-5-8), stood out as superior in terms of stability and adaptability and grain yield by HMRPGV. Commercial cultivars 13 (BRS-Tumucumaque) and 26 (BRS-Itaim) had high grain yield, adaptability, and specific stability in the evaluated edaphoclimatic conditions.

“…Para minimizar os efeitos adversos, o consorciamento entre espécies, principalmente leguminosas são recomendados (DANTAS et al, 2015;SANTOS et al, 2016). Vários são os trabalhos realizados sobre o consórcio entre milho e feijão, sendo os mais predominantes no Brasil (CARVALHO et al, 2017;SOUZA et al, 2011).…”
