Buried Clay Pipe Irrigation, David A. Bainbridge Dec 2012

Buried Clay Pipe Irrigation, David A. Bainbridge

David A Bainbridge

The buried clay pipe method of irrigation is one of the most efficient systems known and is ideal for gardeners and small farmers. Buried clay pipe irrigation uses a buried, unglazed clay pipe filled with water to provide controlled irrigation to plants as the water seeps out through the clay wall at a rate that is influenced by the plant's water use. It has been used for more than one hundred years.This auto-regulation leads to very high efficiency--considerably better than drip irrigation and many times better than conventional surface irrigation. This also reduces weeds, increases yields, and can speed maturity …

Effect Of Weaning Age On Nursery Pig Performance, Alison Smith, Kenneth J. Stalder, Timo Serenius, Thomas J. Baas, John W. Mabry Dec 2012

Effect Of Weaning Age On Nursery Pig Performance, Alison Smith, Kenneth J. Stalder, Timo Serenius, Thomas J. Baas, John W. Mabry

Dr Alison Smith

Weaning age is an extremely important management decision in commercial pork production. The decision is based upon many factors which include sow performance, herd health, pig performance and costs and revenues associated with these factors such as lactation space utilization, and weaned pig value. The industry shifted to weaning litters at earlier ages in order to improve piglet health throughout the nursery and grow finish phases of production. In order to avoid transmission of pathogens from sow to piglet, the Segregated Early Weaning (SEW) concept was developed. This process consists of farrowing sows on the same site as the rest …

Uses Of Wild Plants In Ndumba, Eastern Highlands Province, Terence Hays Nov 2012

Uses Of Wild Plants In Ndumba, Eastern Highlands Province, Terence Hays

Terence Hays

For Papua New Guineans,l as well as for those who wish to understand them better, traiditional knowledge of the local natural environment is a priceless resource. In the face of increasing commitments to a cash economy, however, many communities are rapidly losing their awareness and appreciation of the rich animal and plant worlds which are immediately available to them. As Powell has recently observed (1976), the recorded information regarding traditional plant knowledge and uses has tended to be widely-scattered in the literature and relatively difficult to access, especially for those who stand to benefit the most from it. A recent …

Cambodia: The Challenge Of Adding Value To Agriculture After Conflict, Sophal Ear Oct 2012

Cambodia: The Challenge Of Adding Value To Agriculture After Conflict, Sophal Ear

Sophal Ear

Conflict can trap a country in poverty and economic stagnation. This chapter presents a case study of agriculture’s role in post-conflict Cambodia. Opportunities exist for improving rural livelihoods in Cambodia through the livestock sector. Even more promising is the rice sector, but only if rice milling (processing) can emerge and replace large unofficial exports of husked rice to neighbouring countries (primarily Vietnam). Value addition has not been Cambodia’s forte. Agriculture’s primacy is undeniable, given that it is the only sector capable of absorbing the 300,000 entrants joining the labour force each year. Agriculture is paramount to the Cambodian economy, accounting …


Do We Really Need New Policies? A Study On Soil Sealing In Egypt, Ahmed Harb Rabia Oct 2012

Do We Really Need New Policies? A Study On Soil Sealing In Egypt, Ahmed Harb Rabia

Ahmed Harb Rabia A.H. Rabia

Egypt has the lowest area of agricultural land per individual in Africa. The agricultural land stands for a total of approximately 3.5 million ha which characterized about 3.5% of the total area of Egypt in 2007. The urban encroachment over arable productive agricultural land in Egypt is common and is called (urban desertification). Therefore, the annual loss of arable land to urbanization is 1.2%. This indicates a serious situation to the agricultural area. the Academy of Scientific Research & Technology (1994) has reported that during the period from 1978 to 1984, the annual expansion rates of the dwelling area ranged …

G03-1522 Damping Off Of Seedlings And Transplants, Laurie Hodges

Laurie Hodges

The shift toward more ecological means of pest control is a driving force in research and in growers' fields. Growers need to understand how the various pathogens causing plant disease respond to environmental conditions and cultural practices — what keeps the level of disease below an economic threshold and how these conditions can be developed and maintained for more sustainable production. This NebGuide provides information on two common pathogens that cause seedling disease (damping off) in many crops. Although vegetable production is used in the examples, the principles apply to many cropping systems.
