Effect of oat and brachiaria intercropped with off-season maize in the grain production and biomass of green manure
This study aims to determine the ideal time of green manures deployment and assess what kind of green manure will produce a favorable quantity of mass for the farming without interfering in the maize production. The experiment was conducted in Toledo - PR in 2013. It was designed in randomized blocks, in a factorial scheme (2 × 3 + 1) with 4 replications; the first factor is the species of intercropped coverage...

Soil survey and soil classification of the Koupendri catchment in Benin, West Africa
Lack of detailed soil data has been a major constraint to hydrological modeling and making of agronomic decisions in the Koupendri Catchment. A soil survey was carried out to characterize and classify the soils of the 11.8 km2 catchment using Soil and Terrain (SOTER) approach. The soils were classified using the soil taxonomy (USDA) and the world reference base for soil resources (WRB) classification systems. The soil...

Grain yield and NPK uptake of wheat (Triticum aestivum L.) as influenced by nitrogen, vermicompost and herbicide (Clodinafop propargyl)
Application of Nitrogen (N) at 150 mg kg-1 soil significantly increased the grain and straw yield of wheat from 2.70 to 8.24 and 4.97 to 9.44 g pot-1, respectively over control. Addition of vermicompost at 1% alone increased the grain and straw yield of wheat from 2.70 to 4.81 and 4.97 to 6.60 g pot-1 respectively over control and in combination with N at 150 mg kg-1 soil further improved from 4.81 to 10.73 and 6.60 to...

Physiological quality and protein patterns of corn seeds produced under water and salt stresses
This study evaluated the effect of water and salt stresses on the physiological quality and on the electrophoresis patterns of heat resistant proteins in corn seeds. The experiments were carried out in the laboratories of seed analysis and biotechnology at the Universidade Federal de Lavras. Corn seeds of the hybrid GNZ 2004 and the inbred line LE 57 were used. The seeds were produced in soils with an electric...

Supplemental irrigation levels in bell pepper under shade mesh and in open-field: absolute growth rate, dry mass, leaf area and chlorophyll
This study aims to evaluate the effect of supplemental irrigation levels on vegetative parameters of bell pepper grown in open field and under shade mesh. The experimental design was a randomized complete block with four replications and ten treatments in factorial scheme (four irrigation levels combined with shade). Irrigation treatments consisted in 0.25, 0.50, 0.75 and 1.0 rate of crop evapotranspiration and the...

Modeling the apparent volume of bamboo culms from Brazilian plantation
Brazil has a great potential for cultivation of bamboo species. However, there is a scarce research on the biometric relationships in such plants, which may represent a limitation for its management and use. This article aims to evaluate six methods for estimating the total apparent volume of two species of the genus Bambusa, namely: B. oldhamii Munro and B. vulgaris Schrad. Ex J.C....

Growth, productivity and fatty acid composition of oils of peanut genotypes submitted to different levels of water replacement
The aim of this study was to evaluate the agronomics, physiological and biochemical characteristics of different peanut seeds and plant genotypes. The procedures have been performed during the secondary crop in the agricultural year 2013 to 2014, after the peanut harvest in Barbalha, Ceará – Brazil. The experiment was laid out in split-plot in randomized complete block design with four replicates,...

Effects of fertilizer type on chlorophyll content and plant biomass in common Bermuda grass
Use of biological fertilizers is one of the most important steps in remediating soil contaminated by chemical fertilizer on Bermuda grass. Four fertilizer treatments were examined in the greenhouse. Plant biomass and chlorophyll meter measurements were determined. Results showed that high rate of bio-fertilizer, fast-release and slow-release fertilizers had better shoot and whole plant dry weight than other treatments...

Foliar application of zinc fertilizer on different schedules of application, as cover in the winter maize
Corn is the most important crop in the world market, being greatly used for human and animal nourishment. Corn has limited production with the zinc deficiency of the Brazilian soils which requires proper and correct application for optimizing its productivity. This study aims to evaluate the foliar application of zinc at different times in the corn variety RB 9110 PRO. Analyzing zinc absorption with influecia...
