Abstract: Cabbage is one of the main vegetable crops grown in Cameroon. However, production is limited by rising prices and the scarcity of chemical fertilisers on the market. The rise in cost of fertilizers leaves some farmers reluctant to use fertilisers and as a result leads to lower yields, hence, low crop profitability. The aim of this study was to compare the two systems of agriculture; agroforestry system with the conventional system on the growth of cabbage (Brassica oleracea L.). Research plots were established on the campus of the University of Dschang, in the West Region of Cameroon. The comparisons were made on the basis of productivity, pest abundance and economic profitability. Data on yield and pest susceptibility variables were collected during the field trials. It was realised that the slug (Deroceras reticulatum) population was higher in the agroforestry system (4.62±2.41 slugs) than in the conventional system (1.03±0.55 slugs). The aphid population (Brevicoryne brassicae) was higher in the conventional cropping system (25.31±38.94 aphids) compared with the alley-cropping agroforestry system (0.71±0.62 aphids). Productivity variables showed that cabbage yield did not vary between the two production methods. It was 66.08 t/ha and 66.76 t/ha respectively for the agroforestry system and the conventional system. The economic analysis showed that the agroforestry system was more profitable than the conventional system. Thus, growing cabbage in an agroforestry system is an ecological and profitable strategy for agriculture that is more resilient to climatic variations.

Abstract: Food Barley (Hordeum vulgare L.) is important major cereal crop which cultivated widely over the word. It is very important and categorized as food security crop in highlands of Ethiopian. This research was carried out in west region of Ethiopia Arjo, Gedo and Shambo in 2021 and 2022 cropping season with the objective of determine optimum integrated inorganic fertilizer and cattle manure for food barley production. The experiment was arranged with five level of NPS (0,25%, 50%, 75%, and 100%) of recommended combined with four level of decomposed cattle manure 0, 3tone/hectare, 6tone/ha and 9tone/a using RCBD in factorial arrangement and replicated three times. Analysis of variance showed grain yield, 1000sw, biological yield and plant height significantly affected by integrated fertilizer. Highest grain yield 2665kg/ha was harvested from the plot received 100% and 3tone/ha. Harvest index, seed per spike, spike length and number of tillers per spike were not affected by the treatment. The partial budget analysis revealed two treatments integrated 100% in organic fertilizer and 3tone/ha cattle manure and 9tone/ha cattle manure and 50% inorganic fertilizer which their MRR 605 and 1482 respectively were economically feasible. Therefore, the farmers and investors are advised to use these selected treatments for food barley production and soil fertility improvement.
