  The black walnut (Juglans nigra L.) is an underutilized fruit in the mid-hills of Nepal. However, the physico-chemical properties of Nepalese black walnut are almost unavailable in the literature. Four walnut growing districts namely Baitadi, Dadeldhura, Jumla and East Rukum selected and the black walnut collected at commercial maturity from the local markets. The physical properties were assessed following the IPGRI descriptors, whilst chemical composition by the proximate method across the location. The energy content estimated from the fat, protein and carbohydrate values obtained from the proximate content. The nut weight, kernel weight, nut length, nut diameter were found significantly affected by site, while the effect was similar for the kernel ratio (19-23%). A strong positive correlation (r2 = 0.58) was found between moisture and nut diameter, between moisture and nut weight (r2 = 0.52) and between nut weight and kernel weight (r2 = 0.64). The moisture content, crude protein and total ash content were unaffected by site, whilst the crude fibre, crude fat and soluble carbohydrate content were differed by location of sample collection. The proximate revealed the very best fat or oil content in Dadeldhura district (53.05%), the highest crude fibre in East Rukum district (7.26%), whilst the carbohydrate was found highest in the Jumla (24.69%). The low carbohydrate content in walnut of Dadeldhura might be a hint for the drought tolerance genotype of black walnut. It’s still early to conclude the location effect on black walnut quality without a detailed analysis of environmental and genotypic studies. تفاصيل المقالة

  Aflatoxins are secondary metabolites, which have documented in food and feed such as pistachio.Application of incorrect cultural practices such as animal manures resulted in increasing the density of Aspergillus section Flavi propagules and as consequences increase in aflatoxin content in pistachio nuts. Here, the density of Aspergillus section Flavi propagules, aflatoxin kernel content and characteristics of pistachio fruits in soil surface and fertilizer cannel applications of poultry manure in the orchards in randomized complete block design were compared with control treatment (without poultry manure application). Application of poultry manure on soil surface increased Aspergillus section Flavi propagulesby 4.5 and 11 times higher than compare to those treatments either which not received or in fertilizer channels, respectively. Aflatoxin content in pistachio nuts decreased by 85 and 51 % where poultry manures applied in fertilizer channels and no application compared to surface application, respectively. Overall, poultry manure in fertilizer channel reduced the frequency of blank fruits as well as increasing of splitted nuts and the nuts’ sizes. تفاصيل المقالة
