Influences of inter and intra row spacing on yield, yield component and morphological characteristics of onion (Allium cepa L.) at Western Amhara region
Appropriate spacing enables the farmers to keep appropriate plant population in the field. Hence, it can avoid over or less population in a given plot of land which has negative effect on yield and quality of onion. Spacing of 40 × 20 × 10 cm between furrow, row and plants, respectively has been used for onion production in Ethiopia. But producers complain 10 cm intra row spacing produces large bulb size...

Corn yield as a function of amounts of nitrogen applied in bands
The aim of the current paper is to study the effect of different amounts of nitrogen applied in bands of corn hybrids on variables related to corn plant growth and its yield components. The experiment was carried out under no-tillage system at Guarapuava, PR, Brazil, throughout the period of October 1st 2009 to March 20th 2010. The treatments resulted in the combination of two simple hybrids of corn (P30R50 and AG8025)...

Transmission and effects of Fusarium oxysporum f. sp. vasinfectum on cotton seeds
This paper aimed to evaluate the transmission of Fusarium oxysporum f. sp. vasinfectum (FOV) and the effects of this pathogen on the initial development of cotton plants following inoculation of seeds. Two cultivars (susceptible and resistant) and two strains (most and least aggressive) of the pathogen were used in this study. The inoculation method was based on the contact between seeds and fungal colonies on...

Irrigated sorghum and cowpea after wet-season rice as a pathway out of subsistence agriculture in the Senegal River Valley in Mauritania
Livestock is more important to the Mauritanian economy (13% of National Gross Domestic Product) compared with just 4% from crop production. It is surprising, therefore, that irrigation has so far contributed little to animal productivity given the limited carrying capacity and irregular inter-annual production of the extensive rangeland, and the need to import fodder concentrates to sustain livestock during the hot-dry...

Concepts and key issues of ethnoveterinary medicine in Africa: A review of its application in Zimbabwe
This review is aimed at highlighting the issue of ethno-veterinary medicine (EVM) and the progress and limitations in its application in Zimbabwe.It is a fact that animal diseases are a major constraint to livestock production and development, particularly in communities living in marginal areas affected with endemic pathogens, vectors and diseases. These communities do not have access to modern veterinary information...

Optimization of Blaney-Morin-Nigeria (BMN) model for estimating evapotranspiration in Enugu, Nigeria
The Blaney-Morin-Nigeria (BMN) model was developed for the estimation of reference evapotranspiration (ETo) in Nigeria using commonly available meteorological parameters. In the development of the model, there were some perceived shortcomings which are believed to affect the reliability of ETo estimation, particularly in some specific locations in Nigeria, due to varying environmental factors. This study re-examined the...

Forage intake and performance of cattle in silvo-pastoral systems and monoculture of Marandu in Pre-Amazon region
This work aimed to evaluate dry matter intake (DMI) and performance of F1 Nellore x Guzera with live weight (LW) of 180±15 kg (5 months) on pastures of Brachiaria brizantha cv. Marandu in silvo-pastoral systems composed of babassu palm (Attalea speciosa) and monoculture systems in Pre-Amazonic region of Maranhão state, Brazil. Animals were evaluated in four systems: 0, 80, 131 and 160 adult palms...

Broccoli growth and nutritional status as influenced by doses of nitrogen and boron
Proper growth and development of broccoli may be affected by the application of N and B. Accordingly, the objective herein was to verify the effects of N and B application on growth and the nutritional status in the vegetative phase of broccoli. The experimental design was a completely random one in a factorial (4 × 2 +1) scheme, with four doses of B (0.25, 0.50, 1.00, and 2.00 mg dm-3) and two doses of N (200 and...

Alternative control of Corynespora cassiicola in papaya seedlings and fruits by Cinnamomum zeylanicum essential oil
The study aimed to evaluate the efficiency of essential oil concentrations on Cinnamomum zeylanicum leaves as a possible fungicide against mycelial growth, and the sporulation of Corynespora cassiicola in papaya seedling and fruit. The study performed three experiments, namely comparison of the anti-C. cassiicola activity of: 1 µL mL-1 C. zeylanicum essential oil, commercial fungicide, and control-treatment;...

Chemical characteristics of fruits of two species of Physalis under nitrogen fertilization
Although small fruits, with some exceptions, are not yet as popular in Brazil, some farmers have invested in this market and the genus Physalis can be an important alternative source of income due to its high added value and possibility of cultivation in small areas. To date, there are no specific fertilizer recommendations for even the most cultivated species (Physalis peruviana) and therefore the goal of this study...

Physiological quality of hybrid maize seeds through respiratory and enzymatic activities
With the increased demand for high quality maize seeds, the market absorbs innovations that add speed and reliability in the tests that enable differentiation of potential performance of seed lots. This study aims to evaluate the combination of the physiological tests with the expression of enzymes of respiratory route for differences in vigor levels in lots of hybrid seed corn. The percentage of germination,...
