The effect of zeolite, organic and inorganic fertilizers on soil chemical properties, growth and biomass yield of apple trees
The objective of this study was to evaluate the influence of organic (cattle manure) and inorganic fertilizers [composite NPK (15:15:15)] and natural zeolites on soil properties, vegetative growth and yield of apple plants grown on vertisol under Cacak conditions (Western Serbia). The results showed that the combined fertilization induced a decrease in acidity, an increase in humus content, a p...

متن کاملMixed infection of CTV and HSVd in yellow corky vein disease of Washington navel orange trees
Abstract Hop stunt viroid (HSVd) and Citrus tristeza virus (CTV) are the causal agents of most important diseases of citrus. Previously we reported a novel variant of HSVd that constantly associated with the yellow corky vein disease. Here, 19 individual citrus leaves with yellow corky vein symptoms were sampled for CTV by ELISA. In this study, most symptomatic samples were found to be inf...
