Agricultural characteristics and evaluation locations of sorghum plots with different eucalyptus arrangements

The aim of the experiment was evaluate agronomic characteristics of grain sorghum plots, collected at different sites within four spatial arrangements of eucalyptus for the forest crop livestock integration system (iLPF). The work was implemented in the second crop in the agricultural year 2011-2012, after the soybean harvest in Uberlândia, Minas Gerais. For this, they were planted in areas adjacent seedlings of...

Phosphorus availability from natural and soluble phosphate sources for irrigated corn production

This research’s aims were to evaluate the mixture ratios of P fertilizers in irrigated corn yield in two seasons as well as evaluate the capacity of Resin and Mehlich 1 extractors to predict the P availability under field conditions in two soils: Hapludults and Oxisol. In the first crop, the experimental design was randomized block with four replications where two P sources, Triple Superphosphate (TSP) and Daoui...

Farmer perceptions on the use of non-conventional animal protein sources for scavenging chickens in semi-arid environments

For sustainable intensification of village production systems, it is important to understand the views of farmers who keep the chickens on the utilization of available protein sources. The objective of the study was to assess farmer perceptions on the use of non-conventional animal protein (NCAP) sources for scavenging chickens. Resource-poor households of Msinga local municipality in uMzinyathi district, KwaZulu-Natal...

Lead (Pb) and Cadmium (Cd) levels in fresh and smoke-dried grasscutter (Thryonomys swinderianus Temminck) meat

Muscle, liver and kidney of wild and domesticated grasscutters were analyzed in order to determine the Lead (Pb) and Cadmium (Cd) concentrations. Meat samples were obtained from four different origin. A total of twenty-four (24) samples were used. An atomic absorption spectrophotometer (AAS) was used for the analysis after wet digestion of the samples with 1:3 Perchloric acid and Nitric acid. Data obtained were...

Seeds germination and early development of beggartick on extracted soil solution from an area with cover crops

Plants produce and store many products of secondary metabolism that are released into the environment and can influence direct or indirectly on nearby organisms. Thus, this study investigated the allelopathic potential of extracted soil solution from an area with cover crops according to germination and early development of beggartick. Soil solution was extracted in an area where black oats, turnip and hairy vetch were...

Genetic divergence of corn cultivars in relation to grain productivity, crude protein content and amino acid profile

The aim of this study was to investigate the genetic variability among early-maturing and extremely early-maturing corn cultivars in relation to grain productivity, crude protein content and amino acid profile to obtain future crosses of cultivars with improved nutritional characteristics. Data from two experiments, which were both conducted in randomized block design and three replicates. Thirty-six early-maturing and...

Nitrogen availability modulating the growth of improved genotypes of Coffea canephora

Studies quantifying the effect of the nitrogen over the growth of genotypes of Conilon coffee contribute to improve the fertilization management. Thus, this study was developed to evaluate the growth of improved genotypes of Coffea canephora Pierre ex Froehner submitted to nitrogen fertilization. Six improved genotypes of C. canephora, from different groups of ripening cycles, were grown without nitrogen fertilization...

Pod quality of snap bean as affected by Nitrogen fixation, cultivar and climate zone under dryland agriculture

Snap bean (Phaseolus vulgaris L.) is one of the major vegetable crops in Ethiopia grown for export and local markets. The crop is mainly produced during the dry season under irrigation. Snap bean has higher price than other vegetables in local markets in Ethiopia; however, the high cost of production under irrigation restricts the majority of local farmers from taking this opportunity.  The main objective of this...

Genetic variability studies of fruit yield and its traits among indeterminate tomato genotypes under open field condition

The present study was aimed to investigate the yield and its contributing traits among indeterminate tomato genotypes in order to generate information regarding the extent of genetic variability, heritability and genetic advance. The experiment was conducted using a randomized complete block design with three replications at Vegetable Research Farm, Department of Horticulture, SHIATS, Allahabad during 2012-2013 cropping...

Modeling the effects of different irrigation schedules and drain depths for soil salinity management: A case study from Southern Iraq

Soil-water-atmosphere-plant (SWAP) relationship model is used to evaluate the impact of current irrigation practices on groundwater table depth, soil salinity and crop yields and to determine optimal irrigation requirements and drain depth for the study area. The results indicate that current irrigation practices of applying 600 mm to wheat and 1000 mm to maize are wasting more than 30% of applied irrigation water as...

Bermudagrass fertilization with human urine as a tool to close nutrient cycles: The use of micronutrients

Segregating human urine from wastewater may significantly contribute to diminish the nitrogen and phosphorous problem, considered to be one of the major planetary limits already exceeded. Application of urine diluted in water in agriculture contributes to both sides of the problem. On one hand, it allows reduction of nutrient discharges into receiving bodies, on the other, it reduces the need for reactive nitrogen and...
