Mandarin (Citrus reticulata Blanco) is a promising fruit crop gaining popularity for its human nutrition and economic importance in Nepal. The qualitative losses during pre-harvest stage hinder the productivity subsequently shorten on-tree storability. An experiment was conducted to assess effect of gibberellic acid on quality shelf life mandarin fruit. GA3 at 10, 20, 30 ppm as against control were evaluated. Observations weight (g), firmness (kg/cm2), rind colour (1 - 5 index), juice...

Background . Fresh vegetables such as tomato should have low microbial population for safe consumption and long storage life. The aerobic bacterial count (ABC) coliform (CBC), yeast, mold are the most widely used indicators in fresh which be lower than 4 log CFU g −1 consumption. stages of supply chain, postharvest handling methods, crop varieties had significant effects on population. ABC, CBC, were significantly highest (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...

Mandarin (<i>Citrus reticulata</i> Blanco) is a premier fruit crop expanding rapidly in the hilly areas of Nepal. Most mandarin growers Nepal are using conventional harvesting method which responsible for deteriorating quality and shortening postharvest shelf life. Thus, this experiment was conducted to evaluate effect different methods on shelf-life during storage under Cellar condition (11±2°C 85-90% RH). For this, fruits harvested by i.e. hitting sticks, direct pulling, twisting clipping...
