Irrigation water planning for crops in the central highlands of Ethiopia, aided by FAO CROP WAT MODEL
Information on crop water requirement of crops is vital for irrigation water planning. In the central parts of Ethiopia, agriculture has solely been dependent on rain-fed until recent time that irrigation for vegetable production is becoming one activity for crop production. However, irrigation practice in terms of the amount of water to be used and frequency of application has lacked proper knowledge. The purpose of...

White clover tolerance to herbicides applied at different rates and phenological stages
Glyphosate, 2,4-D, imazethapyr and paraquat + diuron were studied in greenhouse experiments at four application rates in order to evaluate their effects on white clover (Trifolium repens L.) growth and aerial shoot injury at three different phenological stages. Herbicide-induced foliar injury on white clover ranged from no symptoms to early chlorosis, leaf necrosis, stunted growth and death depending on herbicide...

Nutritional valorization of ginger lily fiber (Hedychium gardnerianum, Sheppard ex Ker-Gawl) for animal feeding
Animal production in the Azores is conditioned by the cycles of grass production. In a situation when lack of fiber for animal feed occurs, low quality fibrous foods become relevant. For these reasons, Hedychium gardnerianum (ginger lily), a well-known and traditional source of fiber used by Azorean farmers have been studied. The plant material was subjected to treatments with 5% dry matter (DM) with urea, 3% DM with...

Carcass yield, cuts and body components in lambs fed a pineapple by-product silage diet
The effect of pineapple by-product silage as a substitute for elephant grass on carcass yield, commercial cuts and non-carcass components was evaluated in 25 castrated male Santa Inês feedlot finishing lambs. The lambs had an initial body weight of 18.0±3.4 kg, and they were fed four pineapple by-product silage concentrations (0, 25, 50, 75 and 100%) distributed in a completely randomized design with five...

Diversity of predatory arthropod communities in tobacco-garlic eco-system
Predatory arthropods, especially spiders, play a vital role in the control of insect pests in agro-ecosystems. Accordingly, two year field study was conducted at the Longyan Substation of Fujian Institute of Tobacco Agricultural Sciences in China to determine the effects of garlic and tobacco intercropping system on spiders and predatory arthropods. A total of 545 and 860 (in 2011 and 2012, respectively) individuals of...

Levels of the amino-acid lysine in rations for broilers
Synthetic amino acid supplementation has provided facilities in the adjustment of feed formula, making it possible to obtain the required levels of essential amino acids. Lysine is pronounced the second greatest restrictive amino acid in broiler nutrition. The synthetic amino acid lysine is used as the orientation amino acid in poultry for the reason that it is mainly consumed for protein synthesis. In order to...
