Laboratory, greenhouse, and field experiments were conducted at the University of KwaZulu-Natal, Pietermaritzburg, South Africa in the 2010/2011 and 2011∖2012 seasons to study the effects of eight strains of diazotrophic bacteria on the growth and yield of maize. Maize seeds were treated with Bacillus megaterium (V16), Pseudomonas sp. (StB5, A3, A6, and A61), Burkholderia ambifaria (V9), Entero...

Chlorophyll-deficient individuals have been reported in most species of plants studied intensively by genetic methods. The majority of these chlorotic types have been shown to be the expression of a single gene mutation. However, there is a large group of types that exhibit maternal inheritance, and transmission of the deficiency to their offspring is conditioned by the cytoplasm. Until rather ...

For clean a agriculture and safe environment, this study was conducted, which included the preparation of compost from Prosopis fracta Alhagi maurorum plants, evaluation Its as medium for tomato seedlings production comparing it with peat moss, an organic fertilizer in comparison number fertilizers - poultry wastes, cow sheep wastes spent mushroom residues, results showed superiority prepared o...

this study was performed in order to evaluate the effects of application of super absorbent on the yield and water use efficiency of cucumber under deficit irrigation conditions in greenhouse. plants cultivated in plastic pots and irrigation emitter with four liters per hour discharge was performed. three levels of irrigation water height (10, 8.3 and 6.2 mm day-1) were used as the main factor ...

Plant leaves grow and change their orientation as well their emission of chlorophyll fluorescence in time. All these dynamic plant properties can be semi-automatically monitored by a 3D imaging system that generates plant models by the method of coded light illumination, fluorescence imaging and computer 3D reconstruction. Here, we describe the essentials of the method, as well as the system ha...
