Grapes are one of the important fruit crop in the world, with production rates of approx. 50 million tons per year (Schieber et al., 2001). Grapes can be decay during pre harvest and post harvest and post harvest decay of grapes can be due to physical, physiological, or pathological factors. Rachis dehydration is a main decay factor (physical deterioration) of grapes during the pre or postharve...

Apple growers, private consultants, and extension specialists have all noted that bitter rot is increasingly common and is causing sporadic but economically significant losses throughout the northeastern and north central apple growing regions of North America. Forty years ago, bitter rot was considered a “southern disease” and apples with bitter rot were rarely observed in northern production ...

This research aimed to analyse the effect of biopesticide and organic liquid fertilizer on weight and quality of apple. The study was carried out in Bumiaji, Batu, East Java (805'S, 11280'E, 1400 m in altitude) on July December 2013. The liquid organic fertilizer (LOF) was produced from water mixed with nitrogen source such as manure, urin, legume leaves, phosphoric powder and an energy sourc...

Water deficit significantly limits dryland rainfed fruit production, so increasing water conservation is crucial for improving fruit productivity in arid and semiarid areas. In this study, we tested two treatments in an apple orchard: 1) PC treatment comprising black plastic mulch (BPM) (in-row) with weed control (inter-row); 2) and PGC treatment comprising BPM (in-row) combined with a summer c...

Objectives: 1. Develop a weather-based model for scheduling fungicide applications to improve disease control and reduce fungicide usage. 2. Evaluate efficacy of various products for control of apple powdery mildew. 3. Evaluate reduced DMI and strobilurin fungicide programs, in combination with inorganic salts, for control of powdery mildew. 4. Evaluate various reduced fungicide programs, alone...

in this study, the effect of foliar spray with calcium chloride (0, 0.75, 1.5 and 3 g l-1) during 2, 4 and 6 weeks before commercial harvesting time of apple fruit cv. ‘gala’ and ‘delbarestival’ which trained in three different systems (v shape, hightech and cordon) was investigated. the results showed that types of training systems and foliar application of calcium can affect on fruits quality...
