Allelopathic weed suppression in agroecosystems: A review of theories and practices

Weeds cause great problems to humankind by interfering in food production, health, economic stability, and welfare. The overuse of synthetic herbicides for weed control eventually leads to the evolution of herbicide resistant weeds, which also resulted in growing public concern over their impacts upon human health. The intensification of arable farming has also had a simultaneous impact on the environment. This...

Productive performance and evaluation of the carcass and meat of confined lambs in North of Brazil

This study was untaken to evaluate the effects of diets based on elephant grass or sugarcane as roughage and corn meal or rice bran as energy concentrate on carcass characteristics, meat quality, and the rack of lamb cut characteristics. Thirty-six lambs of undefined breed initially weighing 19.77±1.99 kg were used. A completely randomized design with eight treatments in a 2×2×2 factorial arrangement:...

Assessment of Azadirachta indica and Cleome viscosa liquid-formulations as bio-nematicides in the management of nematode pests of okra

The efficacy of Azadirachta indica and Cleome viscosa liquid-formulations were assessed as bio-nematicides on the performances of okra planted in nematode infested soil at Teaching and Research Farm of Ladoke Akintola University of Technology, Ogbomoso, Nigeria during 2014 planting season. NHAE-47 okra variety which, is susceptible to root knot nematodes, was the test crop. The experimental design was randomized...

Effects of catchment characteristics and climatic conditions on reservoir water capacity in a drought prone area

Crop production in semi-arid sub-Saharan Africa (SSA) is limited by over-reliance on erratic and inadequate rainfall, which often results in yield reduction or total crop failure. The effects of frequent droughts and dry spells need to be circumvented by water conservation. Where rainwater is harvested, research recommendations are based on direct use of the water without relating it to catchment characteristics,...

Evaluation of performance and chemical composition of Petroselinum crispum essential oil under different conditions of water deficit

This experiment aimed to assess the development, yield and chemical composition of Petroselinum crispum essential oil (EO), popularly known as parsley under different levels of water stress deficit: 30  to 40% (moderate stress), 50 to 60% (severe stress) and control 0 to 10%. The plants were kept in a greenhouse to complete the cycle, harvested and measured for their biomass (g), development (cm), yield (%) and...

Biomass production and leaf gas exchange of perennial legumes associated with bananas

The search management for alternatives that reduce the use of mineral fertilizers is important for agricultural sustainability. Therefore, we sought to identify two legume species that are grown as cover crops with banana (Musa spp.) cultivar Prata-anã and spontaneous plant compositions that enable further reduction in the use of inputs. A randomized block design in a split plot arrangement with five replications...

Growth, nutrient accumulation and nutritional efficiency of sunn hemp in function of nutrient omission

The inadequate supply of nutrients in sunn hemp comprises nutritional requirements and efficiency, causing a decrease in the growth and inducing specific nutritional disorders. For this reason this research sought to evaluate the effect of N, P, K, Ca and Mg restriction on nutrient accumulation, nutritional efficiency, plant growth and characterize the visual symptoms of nutrient deficiency in crotalaria. The experiment...

A study on prevalence of bovine trypanosomosis in selected areas of Konta Special Woreda, Southern Ethiopia

A cross-sectional study was conducted from November 2010 to March 2011 to determine the prevalence of bovine trypanosomosis, to identify the species of trypanosomes in the study area and to assess the community awareness regarding the effect of trypanosomosis and control methods in selected areas of Konta Special Woreda of Southern Nation Nationalities and Peoples Regional States. Thirty households were interviewed...
