Seed Quality Of Soybean (Glycine Max [L.] Merrill) Genotypes Under Varying Storage And Priming Methods, Mother Plant Nutrient Profiles And Agro-Ecologies In Kenya

ABSTRACTSoybean 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 m...

Effect of Bio-fertilizer and Seasonality on Growth, Yield and Quality of Two Sunflower (Helianthus annuus L.) Hybrids at Shambat, Sudan

ABSTRACTA field experiment and quality was conducted on a silty loam soil located atDemonstration Farm of the College of Agricultural Studies, Sudan Universityof Science and Technology at Shambat, Sudan, during two growing summerand winter seasons of 2011/2012 to study the effect of bio-fertilizers ongrowth, yield of two hybrids of sunflower. The effect of bio-fertilizers on thesoil were also determined. The bio-fertilizer levels were (Zero, 06.25, 12.5,18.75 and 25.00 L/Ha) correspondin...

Effect of Soil Amendment And Seed Extraction Techniques on Seed Yield And Quality of Pepper (Capsicum chinensis) in Southern Senegal

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 ...

Effects Of Low Dose Gamma Radiation On Quality And Storability Of Groundnut Seed (Arachis Hypogaea L.)

ABSTRACTThe 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;...

Effect Of Seed Priming On Generation And Seedling Development Of Pepper Under Salinity Stress

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 s...

Assessment Of Four Plant Extracts As Maize Seed Storage Protectants Against Sitophilus Zeamais And Prostephanus Truncatus In Ghana.

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 ...

Effect Of Various Combinations Of Organic Fertilizers On Yield And Its Components And Evaluation Of Three Extraction Methods On Seed Quality Of Tomato (Lycopersicon Esculentum) In Ghana

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 condi...
