| The nutritional benefits and functional potential of chia seeds have been highlighted in the literature. However, few studies address the planting system of the species, especially its spatial arrangement. Thus, this study proposes to evaluate chia cultivation under different spatial arrangements, aiming at its agronomic performance. The experimental design was randomized in blocks in a 3×2 factorial scheme, with three inter-row spacings (0.30, 0.45, and 0.60 m), two plant densities per linear meter (7.5 and 15 plants m−1), and four replications. Plant height, stem diameter, leaf area index, dry matter, chlorophyll index, leaf nitrogen content, panicle size, harvest index, and yield were evaluated. The evaluated spatial arrangements did not influence plant... |

| This experiment was conducted in Ames, Iowa, USA, to compare dry matter accumulation patterns of maize genotypes contrasting in height and leafiness, and to test whether reduction in plant height an leaf number through the use of dwarfing genes or earliness can improve grain dry matter allocation. Five plant genotypes were tested: a full season hybrid adapted to central lowa (NK 4525), a short season hybrid adapted to northern Minnesota (C1070), and three dwarf lines (156-A, 302-E and I17- A). The dwarves contained, respectively, the homozygous, independent, recessive dwarfing genes d3, d1 and br2. Each genotype was sown at four plant populations: 25, 50, 75 and 100.000 plants. ha-1. Hybrids had the greatest rates of decrease in total biomass and grain dry... |

| El chile manzano (Capsicum pubescens R. y P.) es originario de Perú y Bolivia, fue introducido a México a principios del siglo XX. Este tipo de chile se produce a altitudes de 1700 a 2500 m. En La Sierra Norte de Puebla la producción de este cultivo se hace a nivel de traspatio, con manejo insuficiente de fertilización y control de plagas. Como parte de una propuesta para mejorar el manejo de este cultivo, y hacer uso de los recursos disponibles en la región, que también se dedica a la ganadería para producción de leche, se compararon dos sistemas de producción, uno con fertilización orgánica y otro con fertilización química, en rendimiento y la calidad del fruto de chile. En el sistema con fertilización química la dosis 200-100-200 (NPK), se fracciono en... |

| The objective of this study was to assess the impact of genetic breeding on grain yield, and to identify the physiological traits associated to the increment in yield and their related growth processes, for wheat cultivars grown in Southern Brazil, in the past five decades. Seven wheat cultivars released between 1940 and 1992, were compared for physiological aspects associated with grain yield. Grain yield, biological yield, biomass partitioning, harvest index and grain yield components were also determined. The number of grains per square meter was more affected by plant breeding and was better correlated with grain yield (r = 0.94, p<0.01) than with grain weight (r = -0.39ns). The higher number of grains per square meter was better correlated with the... |

| Studies of physiological parameters associated with crop performance and growth in different groups of upland rice (Oryza sativa L.) may support plant breeding programs. We evaluated the role of gas exchange rates and dry matter accumulation (DMA) as traits responsible for yields in a traditional (cv. ‘Caiapó’), intermediate (cv. ‘Primavera’) and modern (cv. ‘Maravilha’) upland rice cultivars. Leaf gas exchange rates, DMA, leaf area index (LAI), harvest indexes (HI) and yield components were measured on these genotypes in the field, under sprinkler irrigation. Panicles per m2 and DMA at flowering (FL) and heading, as well as CO2 assimilation rates (A) were similar across these cultivars. The highest yield was found in ‘Primavera’, which may be explained by... |

| Responses of leaf senescence to P supply could constitute adaptive mechanisms for plant growth under P-limiting conditions. The aim of this study was to evaluate the effects of soil P supply on leaf senescence of common bean (Phaseolus vulgaris L.). Eight P levels, ranging from 5 to 640 mg kg-1 P, were applied to pots containing four bean plants of cultivar Carioca in 10 kg of an Oxic Haplustult soil. Attached leaves were counted weekly, abscised leaves were collected every other day, and seeds were harvested at maturity. The number of live leaves increased until 48 days after emergence (DAE) and decreased afterwards, irrespective of applied P levels. At lower applied P levels, the initial increase and the final decrease of leaf number was weak, whereas at... |

| The present study was carried out to determine the contribution of main stems and tillers to the total yield of two wheat cultivars (Triticum aestivum L.), Cocoraque and BH-1146, under two water treatments: a) normal field conditions, and; b) irrigation, in Londrina, PR, Brazil. The experiment was an eight replication randomized complete block design with treatments arranged in split-plots. Data on total grain yield, main stem grain yield, tillers grain yield, the ratio between tiller and total grain yield, yield components and other 17 traits were collected. The cultivar BH-1146 had a higher total grain yield in relation to Cocoraque under normal field conditions; i, e., under water stress. Main stem grain yield responded positively and significantly to... |

| En relación a la siembra directa el trasplante en el cultivo de chile permite el uso eficiente de semillas, uniformidad en la población y seguridad en la producción. Sin embargo, dicha producción dependerá de la edad de la plántula al trasplante. El objetivo del presente estudio fue evaluar el crecimiento y rendimiento de dos cultivares de chile Guajillo (Capsicum annuum L.) Apaxtleco y Mirasol en función de la edad al trasplante, el manuscrito se presenta en 4 capítulos: Capítulo I. Crecimiento y rendimiento de chile guajillo Apaxtleco y Mirasol en función de la edad al trasplante bajo condiciones de invernadero, en donde se establecieron 3 fechas de trasplante a los 15, 30 y 45 días después de la emergencia (dde). Capítulo II. Crecimiento y... |

| Intercropping is a common practice among farmers in tropical regions of the world and has persisted for years, not only for traditional reasons, but also for certain advantages that helped in its ecological adaptation. In regard to low income farmers with small areas for cultivation, more attention should be given to the cost of production and better land management. Thus, the aim of this work was to determine the best intercropping system of cassava with other crops. The experiment was conducted in an area belonging to the cassava (Manihot esculenta) producers of the Planalto de Minas district in Diamantina, Minas Gerais State, Brazil. The treatments comprised cassava intercropped with maize, beans and dwarf pigeon pea, as well as controls with and... |

| Sensory evaluation of grapes (Vitis vinifera L.) plays a key role in determining the harvest time in grapevine varieties. The harvest time of cv. Carménère is one of the latest of Chile. During the season 2007-2008, the evolution of the appearance of Carménère seeds was evaluated as a harvest criterion, comparing it with the chemical and phenolic ripening. The samples were obtained from an organic vineyard located in Curicó Valley, Chile. Starting at 16 ºBrix, 100 seed berries samples were collected weekly from medium vigor vines in order to register photographically the ventral and dorsal sides of each seed. In addition to the seed tannins percentage, the extractable anthocyanins, total anthocyanins and total polyphenols index, as well as the titratable... |
