Effect of Copper (Cu) application on soil available nutrients and uptake
Effects of annual spraying of copper (Cu) fungicide by cocoa farmers in Nigeria needs immediate investigation to avoid copper toxicity which will affect uptake of other essential nutrients for plant growth. Laboratory and Screenhouse studies were carried out to investigate the effects of Cu application on availability of P, Zn, Fe and growth of maize. In the laboratory, copper was applied as CuSO4 at 0, 10, 20, 30, 40...

Soil hydrophobicity and crop evapotranspiration of two indigenous vegetables under different wastewater irrigations in southwest Nigeria
The increased demand for irrigation to boost food supply has placed emphasis on the use of wastewaters. However, the indiscriminate use of wastewaters could impair soil functions and influence other hydrologic processes. The objective of this study was to evaluate soil hydrophobicity and evapotranspiration of two indigenous vegetables under wastewater irrigation in southwest Nigeria. The study was a factorial...

Analysis of the laying characteristics of Nera black hens in a hot and humid environment
The study was conducted to analyze the laying characteristics of Nera black hens in a hot and humid environment and assess the physical characteristics of good, intermediate and poor layers. Seventy-five eight months old Nera black hens of mean body weight 1.35 ± 0.24 kg (range: 1.20 -1.65 kg) in their 12th week of lay and housed individually in battery cages were used for the study. Eggs were collected daily and...

Impact of age and gender on postural stress of dairy workers
Postural stress was measured by assessing time spent in different body postures, frequency of adopting various body postures and angle of body deviations in lumber region of dairy workers during milking. Findings of study suggested that squatting posture was adopted for the longest period of time along with standing posture as a frequently adopted posture by all dairy workers. Further, time spent in different posture...

Initial growth of Moringa oleifera Lam. under different planting densities in autumn/winter in south Brazil
Plant densities that decrease interplant competition can improve Moringa oleifera growth and yield by better use of resources and information about its cultivation in the autumn/winter season is necessary. An experiment was conducted to investigate the viability for the cultivation under the edafoclimatic conditions of the southern Brazil, region of subtropical climate. In addition, it was determined effect of planting...

Study on biochemical constituents of Sclerotium rolfsii, a causal agent of stem rot of groundnut (Arachis hypogaea L.)
Sclerotium rolfsii is a ubiquitous soil-borne fungal pathogen known to cause disease on worldwide range of agricultural and horticultural crops. In spite of economic loss caused by this pathogen, very few reports were available on this aspect, biochemical characterization of the S. rolfsii; hence the present study was under taken to study the biochemical characterization of S. rolfsii. Qualitative and quantitative...
