Changes in climatic conditions are associated with changes the physicochemical properties of many fruits. Four germplasms cashew apple originating from Brazil, Tanzania, Ghana (herein referred to as local) and Mozambique but all grown were studied assess effect agro-climatic zones on sugar accumulation, pH, weight these apples. Cashew apples sourced experimental stations Bole Wenchi Northern Sa...

the presence of yield systematic risk in agricultural sector is one of the main reasons for facing this sector with huge damages and is one of the restricting factors in developing agricultural insurance in iran. this study explores the presence of systematic yield risk and the extent and severity of yield spatial dependence for apple production in iran. to this end, the apple production region...

the aim of this study was to investigate the effect  of irrigation period on the quality and quantity of yield and some morphological and physiological traits of three multigerm sugar beet genotypes named bp mashhad, bp karaj and 191. the experiment was in a split  plot  based on randomized complete block  design , carried out  at motahari research station of sugar beet seed research institute ...

The main reasons for the fixation of some elements and consequently nutrient deficiencies, especially phosphorus, iron and zinc, are high levels of calcium (calcareous soils) and soil pH. Two sulfur fertilizers (sulfur alone and sulfur + organic material + Thiobacillus spp.) with two rates (2 and 4 kg sulfur/tree) were used to decrease soil pH and availability of P, Fe and Zn in apple trees dur...

The technology of producing fruits containing an increased amount elements essential for the health human body, including silicon, has become very important in recent years. Due to popularity apple tree cultivation Europe, appropriate research been undertaken. aim experiment was determine advisability foliar silicon nutrition cultivation. Apple cultivars ‘Gala Schniga’, ‘Ligol’ and ‘Topaz’ were...

considering the increased use of fertilizers and pesticides in agriculture in recent decades and increasing risks of diseases and environmental hazards in human society’s , standards of remaining pesticides in food and agricultural products required to be considered.in this study, residues of chlorpyrifos and diazinon in apple in the damavand region evaluated. sampled randomly from the apple or...

Abstract Background and Aims: Apple scar skin disease (ASSD) is one of the destructive diseases of pome fruits which is caused by ASSVd. Case presentation: We report molecular detection of ASSVd in symptomatic apples cv. Red Delicious with simultaneous presence of a new variant of HSVd from Khorasan Razavi province. Conclusion: This is the first report on the association of HSVd with...
