ABSTRACT Soybean is one of the most important sources of protein and vegetable oil in the world. The demand for soybeans in Kenya is high yet production is negligible due to various challenges, one of which is lack of a well-organized soybean seed system. Soybean seed has been known to deteriorate rapidly in the tropics but the rates vary with the environment, initial quality of the seed and genotype. The broad objective of the research was to enhance soybean seed longevity and vigor through ...
ABSTRACT A field experiment and quality was conducted on a silty loam soil located at Demonstration Farm of the College of Agricultural Studies, Sudan University of Science and Technology at Shambat, Sudan, during two growing summer and winter seasons of 2011/2012 to study the effect of bio-fertilizers on growth, yield of two hybrids of sunflower. The effect of bio-fertilizers on the soil were also determined. The bio-fertilizer levels were (Zero, 06.25, 12.5, 18.75 and 25.00 L/Ha) correspon...
ABSTRACT Vegetable production in general and pepper production, in particular, is of paramount importance in the economic life of rural and peri-urban farmers in Senegal. However, high input costs such as seeds and chemical fertilizers are a limitation to the sector's growth. In order to find technologies capable of producing quality seeds with cheaper inputs, this study was conducted at the Djibelor Agricultural Research Centre in the southern region of Senegal. Six treatments T1 (NPK 300 k...
ABSTRACT The effect of selected low gamma radiation doses on the quality and storability of groundnut seeds cv. Chinese was studied for five months under ambient storage conditions. Six radiation doses (0,1,2,3,4 and 5 Gy), two groundnut seed forms (shelled and unshelled) and eight tri-weekly intervals were combined using Completely Randomised Design with three replications. Physiological parameters (germination percentage, speed and peak value of germination; seedling, root and shoot lengths...
ABSTRACT Salinity stress affects crop production in various stages of plant growth with germination and seed development being the most sensitive to this stress. The need to raise uniform seedlings with better crop establishment is of utmost importance. Various seed priming methods have been employed in many crops to alleviate the effect of saline, drought and temperature stress. The objective of this study was to evaluate NaCl and PEG priming for enhanced germination and improved seedling ...
ABSTRACT Sitophilus zeamais and Prostephanus truncatus are two most important storage insect pests of maize in Ghana and Africa as a whole. These insects cause weight loss of about 20 to 90 % of the untreated stored maize seeds. The control of post-harvest pests largely depends on the use of pesticides. Because of the adverse effects of insecticides on humans and the environment, attempts are being made to discover remedies pest management. This study was to assess four plants (Lantana camara...
ABSTRACT Tomato is one of the most important vegetable crops in the world which is either consumed fresh or as a paste. The high cost of chemical fertilizers has led to farmers turning to alternative methods of cultivation like the use of organic manure. Most organic waste can be turned into fertilizer at low cost for crop production. Information on the effects of different extraction duration methods on seed quality and the costs involved have not been documented under production conditions ...
