Predicting grain yields of maize in an Ultisol amended with organic wastes using modified productivity index in Abakaliki, Southeastern Nigeria
Predicting grain yields of maize in soil amended with organic wastes using modified productivity index was studied for three cropping seasons. Soil samples for determination of productivity index and individual productivity indicators for prediction of grain yields of maize were collected from 0 15, 15-30, 30-45, and 45-60 cm depths. Ascribed sufficiency value was assigned to each productivity indicator of bulk density,...

Anthelmintic and antioxidant potential of Fagopyrum esculentum Moench in vitro
One of the limiting factors of sheep breeding is helminth infection, mainly resulting in poor weight gain. The combination of parasite control strategies, including the use of medicinal herbs can reduce the use of chemical anthelmintics. Tanniferous plants, by having phenolic compounds, mainly condensed tannins were associated with anthelmintic action. Fagopyrum esculentum Moench (buckwheat) has flavonoids, phenolic...

Productivity and quality of watermelon as function of phosphorus doses and variety
Although watermelon is one of the major vegetable-fruit crop, management fertilization still lacks information for increased productivity, quality and profitability, and to lower environmental impact. An experiment was conducted in Mossoró, Brasilian city of Rio Grande do Norte, from August to October 2012, to evaluate the effects of doses of phosphorus (P) (0, 45, 90, 135, 180 and 225 kg ha-1 P2O5) in...

Growth indexes, production and tolerance of peanut irrigated with saline water and bovine biofertilizer
Peanut (Arachis hypogaea) is one of the most cultivated oil plant worldwide since it is widely consumed as food. In this sense, this work aims to evaluate the growth, production and tolerance of peanuts under the effect of different levels of electrical conductivities in irrigation water and bovine biofertilizer. The experiment was conducted in a greenhouse located at the State University of Paraíba - Campus IV,...

Soil micronutrients status assessment, mapping and spatial distribution of Damboya, Kedida Gamela and Kecha Bira Districts, Kambata Tambaro zone, Southern Ethiopia
Micronutrients are important for crop growth, production and their deficiency and toxicity affect crop yield. However, the up dated information about their status and spatial distribution in Ethiopian soils is scarce. Therefore, fertilizer recommendation for crops in the country has until recently focused on nitrogen and phosphorus macronutrients only. But many studies have revealed the deficiency of some micronutrients...

Growth and physiology of peanut (Arachis hypogaea L.) irrigated with saline water and biofertilizer application times
The peanut crop has adaptive features to high salinity levels in the soil, due to its morphological and physiological characteristics. The objective of this study was to evaluate the use of biofertilizer in reducing the effects of irrigation water salinity on the vegetative and physiological behavior of the peanut crop, as well as the crop development under saline conditions. The experiment was conducted in a...

Removal of nitrogen and phosphorus from cattle farming wastewater using constructed wetland system
The confined dairy cattle system employs the most modern production techniques with respect to the genetic standards of the herds. The success found in these systems promoted an increase in the number of confined animals and, consequently, an increase in the produced volume of waste, causing the waste from dairy cattle farming to be one of the largest problems in intensive management systems. This effluent has high...

Determination of wheat crop coefficient (Kc) and soil water evaporation (Ke) in Maringa, PR, Brazil
The objective of the present study was to determine the crop coefficient (Kc) of wheat and soil water evaporation (Ke) in Maringá, PR, Brazil. Wheat crop evapotranspiration (ETc) was determined through the water balance method, using drainage lysimeters integrated with soil moisture measurements. The ETo was calculated using the Penman-Monteith equation with climate data from an automatic weather station, then Kc...
