Abstract: Common bean is globally the most important leguminous crop for direct human consumption. In Tanzania, it is the most inter-cropped leguminous crop especially with maize. Characterization of common beans is important for genetic improvement and ex-situ germplasm conservation since it allows identification and awareness of key features of the genotypes. The common beans grown in Tanzania are of different seed colours such as red, red mottled, grey, white, yellow, brown etc. Yellow bean is one of the most traded bean types in Tanzania but there is limited information on diversity of the varieties cultivated across the country. Therefore, the objective of this study was to assess the diversity of yellow seeded common beans found in Tanzania. The study was carried out at Sokoine University of Agriculture, Morogoro, Tanzania in 2022. Thirty-two yellow bean genotypes collected from different regions of Tanzania were assessed for diversity using quantitative and qualitative traits. The trials were carried out in the screen house and on the open field. The data collected were subjected to analysis of variance, cluster, principal component, and correlation analyses. Sixteen genotypes were characterized as determinate plant type while the remaining sixteen were classified as indeterminate. About 75% of the genotypes had cuboid shape while 12.5% had kidney and oval shapes. About 78% of the genotypes were dominated by green cotyledon colour while 90% had white hypocotyls colour. The cluster analysis grouped the genotypes into five groups in both field and screen house. The first four principal components accounted for 51.8% of the variation observed on the field and 61.9% in the screen house. There were strong correlations among many important traits which will allow indirect selection for some complex traits. The positive correlation observed between number of locules and number of seed per pod (r = 0.87) indicates that number of locules can be used to determine the density and seed yield. There was high level of diversity among the yellow bean genotypes evaluated in this study for quantitative and qualitative traits. The scientific information obtained from this study will be useful in breeding programmes for improvement of yellow seeded beans in Tanzania for the traits.

Abstract: Chickpea is a legume with high nutritional value. It is mainly grown in arid and semi-arid areas soils, which are characterized by a deficiency in mineral elements, a severe water deficit and a poor soil quality. Our work aims to evaluate the effect of different mineral elements in the soil on nodular biomass, growth and yield of chickpea. The physico-chemical analyses of the soil and the agronomical and physiological parameters showed that the level of available phosphorus in the soil positively affected the growth parameters in the chickpea studied plants. Our results also confirmed the positive effect of adequate plant P nutrition on yield. Indeed, among the studied fields, agricultural soil 7 presented the highest potassium content and seeds yield (12.87 mg/g DM and 62 seeds per plant, respectively). In parallel, soil 7 recorded the highest value of available phosphorus 23.52 ppm. On the contrary, soil 5 was the least rich in P content (6.73 ppm). A positive correlation was recorded between the sodium concentration in the soil and in the aerial parts (r =0.73). The results also showed that the aerial part was richer in calcium than the root part and the nodules. Moreover, other positive correlations were recorded between the calcium concentration in the soil and in the aerial part and in the root part (r =0.76 and r =0.54; respectively).

Abstract: Tef is stable crop food in Ethiopia. However, many farmers were not food secured and only few model farmers used tef for their daily local food. This is due to the use of low yielder varieties. On the other hand, improved tef varieties were not disseminated for surplus production. Therefore, it is important to find the way of improved tef varieties were disseminated in potential areas of Guji zone. This activity was conducted to popularize improved Dagim tef variety, strengthen stakeholders’ linkage and to improve farmers’ income. Purposively, Adola Rede, Odo Shakiso and Wadera were selected based on their tef potential and suitable for monitoring. Seven (7) kebeles were selected from the selected districts. Totally, 83 farmers were selected for pre scaling up tef at the midlands of Guji zone. In addition, four FTCs were used as multiplication site as a seed source for the next season. 400kg of Dagim variety was distributed. Each farmer was obtained 4.5kg Dagim variety and sown it on 0.25ha. Training was used to enhance farmers’ knowledge and skills on Dagim production and field day was used to motivate farmers to grow Dagim tef variety. The stakeholder had participated during training and field day to strengthen linkage on seed, agricultural inputs and information. Hand weeding and herbicide was used to control weed. Yield, cost of production and farmers perception were collected by interview method. Data was analyzed by descriptive statistics, net income and narration. The yield performance of Dagim variety was 9.82 qt/ha which low compared to national and demonstration stage due to lack of rainfall during 2020 and 2021/22 year. The result of net income showed that production of Dagim variety generated a return of 15735.72 ETB/ha. More net income (17551.63 ETB/ha) was obtained at Odo Shakiso district followed by Adola Rede district (16503.36 ETB/ha). There was a good yield and income at some farmers who sown Dagim variety at mid of September month. Dagim variety should be disseminated in the midland districts of Guji Zone. Since tef can be produced twice in a year provision of tef variety and fertilizer for farmers should available based the seasons.

Abstract: Food and feed is the most aspect in agricultural sector. Potential land is covered by crop production to feed the increasing human population. Hence, for livestock production feed production is challenging to be solved at farm level. Therefore, balancing the available land for crop and livestock production is critical as the land is fixed resource. This could be achieved by demonstrating year round forage production on small area. This activity was conducted at highland districts of Guji zone to evaluate biomass yield of Desho grasses and to enhance the knowledge and skills of farmers on production of Desho grass. Areka DZF № #590 and Kindo Kosha DZF № #591 desho grasses were planted on 5m×10m with the recommended packages. Knowledge and skills of farmers were taken before and after demonstration. Training and mini field day was organized. Cutting and carry system was used to feed livestock. Measurement, observation and interview were used to collect the data. Plot cover, plant height regeneration and fresh biomass were collected. 17 Knowledge and skills questions were prepared and interviewed to 18 farmers before and after demonstration. Descriptive and t tests were used to analysis the data. The result of descriptive showed that Kindo Kosha DZF № #591 variety had more plot cover (88.47%) than Areka DZF № #590 variety (85.76%). As desho grass is annual forage and regeneration trait was important for livestock feed. Kindo Kosha DZF № #591 variety also provide high in regeneration capacity (85%) than Areka DZF № #590 (83%). More fresh biomass was obtained from Kindo Kosha DZF № #591 (49.78t/ha) than Areka DZF № #590 (47.59t/ha). The result of paired sample test showed that there was a mean significance difference in knowledge and skills before and after on demonstration of desho grasses at 0.001 level. Knowledge and skills of farmers were increased by trainings and field days organized on desho grass demonstration. Both desho grasses were identified and preferred for livestock feed by experimental farmers. Desho grasses were important as feed, soil erosion control and as income generating. Therefore, it is better to pre scaled up these desho grasses at highland areas of Guji zone. To know more advantage of desho grass as livestock feed further research is needed on the effect of desho grass on milk and meat production at the study areas.

Abstract: Squash (Cucurbita maxima Duch) is one of the vegetables-fruits grown and used in human nutrition and in the treatment of many diseases in Burkina Faso. The main objective of this study is to contribute to a better knowledge of the phenotypic variability of the local squash grown in the Passoré province. To this end, an agro-morphological characterization was carried out in a randomised complete block design with three replications under rain-fed conditions in a Sudanese-Sahelian climate. A total of 32 variables, including 21 quantitative variables and 11 qualitative variables relating to the vegetative development of the plant and fruit yield, were measured. This study has shown the existence of a phenotypic diversity on the color and form of fruits and agro-morphological diversity based on the female characters flowering time (FLF), male flowering time (FLM), fruit length (LFT) and fruit diameter (DMF) organized in three (3) morphological groups. The Group 1 is composed of early flowering plants with small leaves and fruits and late maturity of fruits. Group 2 is the opposite of group 1 and is made up of accessions with large fruits and big seeds. As for Group 3 it is composed of high performance accessions with large leaves and fruits of high length and diameter.
