METHODS All accessible larval habitats were surveyed between May and September, 2011 in Osogbo metropolis while Land Use/ Land cover of the city was analyzed using 2 Lansat Multispectral Sca...

in Eastern and Central Nepal. Despite the current situation of the Mikania invasion, quantitative data on the impacts and scale of the problems are lacking for the country. Due to the lack of information regarding scale of invasion, the stakeholders have not put forwarded the proper control mechanism of the species. This paper has made an attempt to analyze the scale of invasion through the com...

Abstract—Nitrogen fertilizer is the most used and often the most mismanaged nutrient input. Nitrogen management has tremendous implications on crop productivity, quality and environmental stewardship. Sufficient nitrogen is needed to optimum yield and quality. Soil and in-season plant tissue testing for nitrogen status are a time consuming and expensive process. Real time sensing of plant nitro...

This study attempts to investigate the impact of the working certification programs on the income of the coffee farms operated by the local smallholders at Dakha District, Kontum, Vietnam. Followed by the comparisons of the socio-demographic and economic characteristics between certified and non-certified farmers, the study adopts the Binary Probit model and linear regression model were applied...

The study identified agronomic practices, analyzed relative profitability, and resource use efficiency of tuberose cultivation in Bangladesh during January 2010. Primary data were collected from 100 randomly selected farmers from Jessore and Chuadanga districts. The results revealed that the per hectare costs of tuberose cultivation were estimated at Tk. 2,00,761 and Tk. 1,29,283 over full cost...

Poultry litter usage in horticultural crop production is a contributor to nuisance fly populations, in particular stable flies (Stomoxys calcitrans L.) and house flies (Musca domestica L.). Extrapolation of adult emergence data suggests that approximately 1.5 million house flies and 0.2 million stable flies are emerging on average from every hectare of poultry litter applied as a preplant ferti...

Primary data were collected from fourteen seed growers using structured questionnaire. The analytical tools employed include descriptive statistics and average net farm income. Results revealed that the average total cost of production p...

Research was conducted to evaluate various pink bollworm pheromone dispensers; the Conrel hollow fiber dispenser, gossyplure treated rubber tubing dispensers utilizing either a hexane or methylene chloride solvent, aged dispensers, and dispensers treated with aged pheromone<, Although results varied depending on the time of year, the Conrel dispenser was generally least effective. The two solve...

--The habitat requirements of open nesting birds were examined in 19, five hectare, plots arranged along an altitudinal gradient in western Montana. Seven, mature forest birds were examined in detai 1. Percent shrub and low canopy cover {0.5-1.5m), mid-canopy cover {8-25m), and the number of large diameter stems {25-50 em dbh) were of major importance to this avian co11111unity. Increased avian...

The impact of nitrogen fertilization on cotton plants, Gossypium hirsutum L., silverleaf whitefly, Bemisia argentifolii Bellows & Perring, population dynamics and honeydew production were investigated in the field at Riverside, California, USA. Treatments were soil applications of 0, 112, 168 and 224 kg nitrogen per hectare, and a soil application of 112 kg of nitrogen plus a foliar application...
