Effect of planting space on plant population at harvest and tuber yield in taro (Colocasia esculenta L).

A two  year study was carried out in two locations in south eastern Nigeria in the years 2008 and 2009, to determine the effect of planting space on plant population at harvest, and corm yield in cocoyam cultivars. This was aimed to identify optimum planting space for optimum cocoyam production. Five taro cultivars; Nkpong, Ugwuta, Nworoko, Odogolo and Nadu were used. Three planting space; 50 x 100 cm, 40 x 100 cm...

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...

Use of micronutrients in tropical and sub-tropical fruit crops: A review

Soil is the reservoir of macro and micro nutrients with the inception of commercial farming the emphasis is given to production without taking care of soil health and eventually soil health deteriorates and production falls. One of the very important components of soil health remained neglected and now reached to the threatening level. Management of balanced nutrients has become of vital importance. Without minimizing...
