Investigating viability of the premium influenced land agro-usage structure for production of African leafy vegetables in Vihiga and Jinja

Land subdivision has reduced land for agricultural production resulting in its intensive cultivation. This has lowered soil fertility which has contributed to reduction in the diversity of African Leafy Vegetables thus restricting the otherwise traditional dietary diversity that was once beneficial to smallholder farmers. As land continues to decline, there needs to be some impetus in place that can retain the diversity...

Allelopathic effect of Casuarina equisetifolia L. on wheat, associated weeds and nutrient content in the soil

Allelopathy is an ecological phenomenon that recently attracted researchers' attention as a new approach in weed control. Pot and field experiments were conducted to study the allelopathic effect of Casuarina equisetifolia L. leaf litter, one of three most common Casuarina species in Egypt. The influence was studied during two successive seasons (2012-2014) on wheat and associated weeds through foliar application of...

Enzymatic and biological assessment of sulfonylurea herbicide impact on soil bacterial communities

Soil microorganisms play an important role in the decomposition of organic and inorganic matter in soil, being capable of breaking down different types of xenobiotic substances in soil. Application of herbicides in crops is commonly used in agriculture to increase agricultural productivity and weed destruction. Two sulfonylurea herbicides (tribenuron methyl and nicosulfuron) were applied to the soil samples in different...

Factors affecting feed intake, body weight, testicular size, and testosterone, follicle stimulating hormone (FSH) and luteinizing hormone (LH) serum concentrations in peri-pubertal male camels

Body weight, testes development and serum testosterone, follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels were determined and compared in two groups of peri-pubertal male dromedaries. Daily maximum and minimum ambient temperatures and dry and wet-bulb temperatures were recorded. Temperature-humidity index was calculated. The camels were divided into two equal groups of nine camels each, of...

The search for productivity and pre-harvest sprouting tolerance in wheat

The pre-harvest sprouting (PHS) in wheat Triticum aestivum L. is a phenomenon that reduces productivity, degrades starch and depreciates the quality of flour. The objective was to evaluate the per se performance of traits linked to grain yield and tolerance to pre-harvest sprouting in wheat genotypes from different breeding programs in Brazil. Besides, to use indirect selection based on traits showing beneficial...

Reduction in growth and aflatoxin production in orange juice inoculated with Aspergillus flavus using aframomum danielli

The survival and production of aflatoxin by Aspergillus flavus introduced into pasteurized (85°C;15 min) and unpasteurized orange juice treated with Aframomum danielli (local preservative) extracts at 0, 1, 2, 3, 4, 5 and 6% concentrations were investigated at 3 and 7 days of storage on shelf (28±2°C). There was slight increase in pH on day 3 which was more prevalent on day 7(4.77-6.85 and 6.07-7.37) for...

Trinexapac-ethyl in the vegetative and reproductive performance of corn

This study aimed to measure the effects of rates of plant growth regulator trinexapac-ethyl on the development of the aerial, root parts and yield components of corn. The experiments were conducted in a greenhouse: one assay was aimed at evaluating the growth and development of the plant, in a 4 x 4 factorial arrangement, with four rates of trinexapac-ethyl (0, 125, 250 and 375 g of i.a. ha-1) and four assessment...

Concentration of nutrients and chlorophyll index in pigeon pea fertilized with rock phosphate and liming in cerrado oxisol

Soil fertilization and the management of green manure are needed to maintain and increase the soil fertility of Cerrado. Thus, the objective of this study was to evaluate the concentration of nutrients in the shoots and roots of pigeon pea that was fertilized with phosphorus sources that are associated with liming in Cerrado Oxisol. This study was conducted in a greenhouse with a completely randomized design in a...

Broadcast fertilizer rate impacts common bean grain yield in a no-tillage system

Increasing fertilizer rates at sowing can provide significant increases in grain yield in vegetable crops. However, very high rates can impair root development because of increased soil salinization in the rows mainly because of KCl fertilizer. Broadcast fertilization without incorporation into soil may be a viable strategy to avoid this salinization. Therefore, we conducted a study to determine the effect of different...
