The objective of this work was to evaluate Zn use efficiency by upland rice genotypes. The experiment was carried out in a greenhouse, with ten upland rice genotypes grown on an Oxisol (Typic Hapludox) with no application, and with application of 10 mg kg-1 Zn, applied as zinc su...

Ten Solanum potato genotypes, including four primitive species and six hybrids, were grown to maturity near 230 and 3273 meters in elevation at two sites, Coast and Sierra, in Peru. Growth data, with emphasis upon tubers and leaves, were collected periodically to analyze the plan...

The goal of this work was to determine four biometeorological indexes: degreedays (DD), Primault s biometeorological index (BI), Huglin s heliothermal index (HI) and Geslin s heliothermal index (GHI) for grape Niagara Rosada (Vitis labrusca L.) pruned at different seasons and phy...

ABSTRACT Nitrogen is considered the most limiting nutrient for cassava, and N availability can influence the crop cycle, including earlier harvest. The aim of this study was to study the effect of harvest time on the production components of cassava, “Aciolina” cultivar, at diffe...

Abstract The aim of this study was to verify if the harvest index (HI) of common bean is higher in modern lines, to verify if its estimate varies with the cycle of the plant and environmental conditions, and to obtain information concerning its genetic control (through diallel cr...

Quality control is used to evaluate processes and products, and is a powerful tool for reducing variability. The objective of this study was to evaluate the quality of green sugarcane (Saccharum spp.) cutting for mechanized harvest, using statistical quality control tools. Cuttin...

ABSTRACT The quality control is used for the evaluation of processes and products, and it is important to detect and reduce variability and in operations management can be applied in mechanized harvesting of sugarcane billets. In this sense, this study aimed to identify critical ...

The aim of this study was to evaluate the phenotypic characteristics of sweet corn as a function of seed inoculation with Azospirillum brasilense associated with nitrogen fertilization at "Summer" Harvest of 2012/2013 and "Autumn-Winter" of 2013, in Parana Northwest. The experime...

ABSTRACT Kale plants are usually sold “in natura” in street markets and malls. Kale leaves can have their appearance compromised by dehydration and discoloration due to increased post-harvest time exposure. We aimed to analyze the Global Stability Index (GSI) in kale accessions b...

This study aimed to evaluate the growth, assimilate partitioning and seed vigor expression of rye seeds subjected to waterlogging during development. The experimental design was completely randomized with six replications and three treatments. The treatments involved different wa...

Experiments were carried out with the objective to evaluate the efficiency of methods for prediction of bitter pit occurrence, on Gala, Royal Gala, Fuji and Braeburn apples after controlled atmosphere storage (CA). Fruits from 11 orchards were picked 20 days before and at commerc...

Abstract: The objective of the study was to evaluate the growth and production efficiency of forage-grain dual-purpose wheat in two arrangements and four agroforestry systems (Intercrop-I and Intercrop-II), as well as to evaluate crop management for the wheat crops in two planti...
