Espaçamentos entre plantas e cobertura do solo com cama-de-frango na produção de ervilhas

The aim of this study was to evaluate the agroeconomic yield of ‘Luciana n.o 50’ pea grown within three spacings between plants (5.0; 7.5 and 10.0 cm), with and without soil covering with poultry litter. Treatments were arranged in a 3x2 factorial in randomized complete block design with five replications. The highest fresh (8.33 t ha -1 ) and dry (2.02 t ha -1

Influência da cama de frango e de espaçamentos entre plantas na produtividade agroeconômica de mandioquinha-salsa

Peruvian carrots is an excellent alternative for small and medium farmers, especially within the concepts of family farming. Thus the aim of this study was to evaluate the agricultural economic yield of this crop when managed under two plant spacing arrangements (20 and 25 cm between plants) and different application methods of dried broiler manure on the soil [surface-applied (10 t ha-1); incorporated to the soil (10 t ha-1); surface applied (5 t ha-1) + incorporated (5 t ha-1)]. Two harvests were performed in different stages of maturation, when plants presented 50% and 70% senescence, at 224 and 249 days after planting (DAP), respectively. The characteristics evaluated were not significantly influenced by the interaction between the plant spacing arrangements and the methods of broiler manure addition, although they were influenced by isolated studied factors. Greater fresh weights of leaves, crown and shoots were obtained under 25 cm plant spacing arrangement in both harvests: there were increases of 27% (leaves), 28% (crowns) and 37% (shoots) for 50% senescence; and 25% (leaves), 13% (crowns), 18% (shoots) and 22% (commercial roots) for 70% senescence, when compared to those obtained under 20 cm. With 70% senescence, the greatest yields of commercial roots were attained when the addition of broiler manure was incorporated on the soil or surface applied + incorporated, outgrowing 10.27 ton ha-1 and 7.29 ton ha-1, respectively, in comparison with those produced without manure. Thereby, to achieve greatest yield of commercial roots and higher net income, the Peruvian carrot crops should follow spacing of 25 cm between plants, with broiler manure incorporated to the soil, as well harvests performed when plants reach 70% senescence, at 249 DAP.

Produtividade agronômica de genótipos de amendoim Virginia cultivados com diferentes espaçamentos entre fileiras no canteiro

Aims of this work were to know the yield capacity and the net income of two peanut genotypes grown under three spacing between rows. Treatments were arranged as 2 x 3 factorial scheme in randomized blocks design, with five repetitions. The harvest was carried out at 227 days after sowing. The interaction between genotypes versus row spacings did not demonstrate correlation. The highest fresh and dry matter yield of shoot (branches + leaves) were of plants of Pintado peanut that significantly exceeded in 70,42% and 78,76% respectively the than Marrom peanut. Highest weight of fresh and dry matter yield for commercial pods, non-commercial pods, and seeds was not significant statistically for genotypes and the spacing between rows. The genotype Pintado produced 39,46% more than Marrom of fresh matter yield (g) of 50 pods, and percentage yield seeds were 12% higher for Marrom than Pintado, both of the results with significant difference. For fresh matter (g) of seeds (relative to 50 pods) and number of seeds/pods did not have significant difference between spacing and genotypes.
