Conservation agriculture is a concept which defines different farming systems. Its implementation depends on soil properties, climate and socio-economic considerations. Since two thousands, no-till technology; which is one facet of the conservation agriculture has begun to take place in the high plains of Sétif province-Algeria. Its adoption is facing several problems of socio-economic and technical issues. This work monitored the track of no-till adoption within a sample of 28 farmers during two years 2014 and 2016. During 2014 farmers were supported financially and technically through a subsidy program that aimed at the support of conservation agriculture via no-till technique. In 2016, the subsidy program has ended; hence, farmers have no longer incentives. Multivariate statistical analyses were performed to diagnose the evolution of no-till adoption and behavior’s farmers between the two periods. In 2016, results showed an increase of no-till area, even though, the drop of the number of adoptive farmers by 71%. The main reasons for adopting no-till according to the adoptive farmers were the minimization of farming operation costs and saving time. However, the major impediments facing no-till adoption; were the rise of weeding charges and the concern of weed infestation especially by bromus.sp, which is a vigorous prevalent weed, which locally developed some pesticide’s resistance. Also, the excessive use of pesticides may be considered as an environmental reason for no adopting no-till.

The botanical heritage of a region is an important resource for local people, which allows them to treat themselves with plants that have already been experienced from generation to generation for their benefits and effectiveness. The aim of this study was to highlight the different uses of lentisk pistachio products in the region of Jijel (Algeria). Systematic surveys have been carried out among different categories of people, by age group; have shown a growing interest in the use of medicinal plants. Two approaches (observation, and interview) were used to support this study, with an ethnobotanical worksheet, to obtain other recipes and more information on lentisk benefits and uses. The survey data processing showed that the lentisk is used for therapeutic purposes, to treat diseases of the skin (29%) and respiratory system (28%). The main and most used part of the plant is its berries. The plant is harvested in a spontaneous state and the picking of berries is done from November (in winter). Oil extraction is the principal preparation (72%). The use of resinous gum was not mentioned. Ten percent of surveys gave culinary recipes for some traditional meals preferred by Jijelians. The current study highlighted the ancestral practices and uses of the lentisk by Jijelians. It is necessary to develop this niche and promote its value chain in order to consolidate the economy of the local population.
