Buckwheat is a sixth staple food crop after rice, wheat, maize, finger millet, and barley in Nepal. It is considered as an alternate cereal and poor man’s crop, representing an important food supply in remote places of Himalayas. It is the best crop in higher altitude in terms of adaptation to different climatic variables and easily fitted to different cropping patterns due to short duration. It is cultivated on marginal land in 61 out of 75 districts of Nepal from some 60 m to 4500 m asl, especially hilly and mountain districts like Rukum, Rolpa, Jajarkot, Dolpa, Humla, Jumla, Kalikot, Kavre, Dolakha, and Okhaldhunga. Sweet buckwheat varieties are generally grown in midhill and Terai but Tartary buckwheat varieties are grown in higher altitude. There are altogether 19 local landraces of sweat buckwheat and 37 for Tartary buckwheat listed from Nepal. The largest producers are China, USA, and Russia and Japan is principal user of global buckwheat grown in the world. In Nepal, it is cultivated in 10510 ha area with production of 10355 t/yr and yield of 0.983 t/ha. It has also medicinal value used in different forms including all its parts so the demand of buckwheat is increasing.

ABSTRACTWe used CRISPR-Cas9 in the staple food crop cassava with the aim of engineering resistance to African cassava mosaic virus, a member of a widespread and important family of plant-pathogenic DNA viruses. We found that between 33 and 48% of edited virus genomes evolved a conserved single-nucleotide mutation that confers resistance to CRISPR-Cas9 cleavage. Our study highlights the potential for virus escape from this technology. Care should be taken to design CRISPR-Cas9 experiments that minimize the risk of virus escape.

Wheat [Triticum aestivum (Linnaeus) Em. Thell] belongs to family Gramineae, believed to have originated from South West Asia. It is most important cereal cultivated crop in temperate area of the world. Wheat is second important staple food crop after rice. In field condition the termite (Odontotermes obesus Rambur) is predominant insect-pest causing 20-40% damage to the crop particularly in rainfed condition. For the management of termite in wheat, Krishi Vigyan Kendra demonstrate the technology - Seed treatment by Fipronil 5% SC @ 6 ml./ kg seed before sowing and soil treatment by Fipronil 5 % SC @ 1.6 lit./ha. During 2016-17 and 2017-18 at farmers field in adopted village of KVK conduct the demonstration. Under the technology, reduce the termite infestation 53.46 per cent resulted18.92 per cent enhance the productivity of wheat crop. Under IPM technology, the average productivity of chickpea is 3865 Kg/ha whereas in farmers practice, the average productivity of chickpea is 3250 Kg/ ha.

Enset (Enseteventricosum) is a traditional multi-purpose crop mainly used as a staple/co-staple food crop over 20 million people in Ethiopia. The Gurage are sedentary agricultural people of patrilineal persuasion who speak a Semetic language and inhabit in a sparsely fertile semi-mountainous regionin south-central Ethiopia. Enset, their staple food crop, commonly called the “false banana plant”, is produced in abundance by each Gurage homestead. The objective of this study was to document the socio-cultural values of enset plant among the Gurage. In this study, a qualitative methodological approach is employed in extracting information from different sources on the subject in question. The study relied mainly on primary and secondary sources.According to findings, three types of food, viz, Kocho(fermented product from scraped pseudo stem grafted corm), Bulla(dehydrated juice), and Amicho (boiled corm) can be prepared from enset. As a food crop, it has useful attributes such as foods can be stored for long time, grow in wide range of environments, produces high yield per unit area and tolerates drought. It has irreplaceable role as a feed for animals. Enset starch is found to have higher and widely used as a tablet binder and dis-integrant and also in pharmaceutical gelling, drug loading and release processes. Moreover, enset shows high genetic diversity within a population which in turn renders resilience and food security against the ever-changing environmental factors and land use dynamics.Enset is totally involved in every aspects of the daily social and ritual life of the Gurage, who, with other several tribes in southwest Ethiopia, form what has been termed “the EnsetCulture Complex Area”. From birth, when the umbilicus is tied off with a fiber drawn from enset fronds, the life of the Gurage is enmeshed with various uses of enset, not the least of which is nutritional.
