O desempenho agronomico de Panicum maximum cv. Tobiata, em cultivo puro e consorciado com cinco leguminosas forrageiras tropicais (Desmodium ovalifolium CIAT-350, Centrosema acutifolium CIAT-52-77 e CIAT-5112, C. pubescens CIAT-438 e Pueraria phaseoloides CIAT-9900), foi avaliado em ensaio conduzido em Ouro Preto d' Oeste, Rondonia. As consorciacoes foram mais eficientes na producao de forragem que a graminea em cultivo puro. O maior rendimento de materia seca foi registrado na consorciacao com C. acutifoium CIAT-5277, o qual nao diferiu (P>0,05) do verificado na mistura com P. phaseoloides. Os teores de proteina bruta da graminea consorciada foram superiores aos obtidos em seu cultivo isolado. As leguminosas que fixaram e transferiram as maiores quantidades de nitrogenio foram C. acutifolium CIAT-5277, CIAT-5112 e P.phaseoloides. |

Abstract: Water availability, light, management practices, and harvest time impacts on Coffea arabica L. yield and bean quality remain uncertain. It was hypothesized that the soil water and light availability could impact berry distribution, yield, and bean chemical attributes within the plant canopy. Therefore, it was aimed to study berry yield, berry distribution, and bean chemical traits along the canopy strata of four coffee genotypes (Iapar 59, Catuaí 99 and two Ethiopian wild accessions, ?E083? and ?E027?), cultivated with (IRR) and without irrigation (NI) in the two initial harvest years. The maximum height of berry occurrence was lower in NI than in IRR plants in both harvest years. In the 2nd harvest year, higher leaf-to-fruit ratio was found under NI than under IRR for all genotypes, except for Catuaí 99, while the most regular berry distribution among canopy strata was obtained in IRR ?E083?, the highest bean yield in IRR ?E083? and Iapar 59, and the highest percent of useful bean biomass in NI Catuaí 99. The reduced lipid content under IRR was more important in the 1st (all genotypes) than in the 2nd harvest year (Iapar 59 and ?E027?). As a novelty, chemical bean composition was additionally impacted by light availability along the canopy strata. Proteins declined from bottom (shaded) to upper (highly light exposed) strata, regardless of genotype and harvest year. Similar stratification was observed in caffeine in the 2nd year. Although some traits were somewhat changed among strata, no substantial quality changes occurred, thus allowing that harvest might include the entire plant and not only some specific strata. Iapar 59 and ?E083? showed chemical composition usually associated with high bean quality, with the highest lipid, sucrose, and soluble sugar contents, and the lowest caffeine, chlorogenic acids, and phenolic components among four genotypes, but Iapar 59 plants were less affected in their yield under NI. Based on additional responses from space occupation and yield only under IRR, the wild accession ?E083? must be considered in future breeding programs as promising material for intensive input conditions. High bean quality and the less variated yield under lower soil water availability qualified the Iapar 59 as the most prominent among the four genotypes.
