“…Four cassava ( M. esculenta , Crantz) cultivars (TME 7, TME 419, TMS 98/0581 and TMS 30572) considered high yielding and with high popularity among farmers in Nigeria (Agwu, Njom, & Umeh, ; Oriola & Raji, ) were used in this study. The cultivars TME 7 (also called “Oko‐Iwayo”) and TME 419 are African landraces, whereas TMS 98/0581 and TMS 30572 are improved cultivars bred by the International Institute of Tropical Agriculture (IITA).…”

Despite the vast importance of cassava (Manihot esculenta Crantz) for smallholder farmers in Africa, yields per unit land area have not increased over the past 55 years. Genetic engineering or breeding for increased photosynthetic efficiency may represent a new approach. This requires the understanding of limitations to photosynthesis within existing germplasm. Here, leaf photosynthetic gas exchange, leaf carbon and nitrogen content, and nonstructural carbohydrates content and growth were analyzed in four high‐yielding and farm‐preferred African cultivars: two landraces (TME 7, TME 419) and two improved lines (TMS 98/0581 and TMS 30572). Surprisingly, the two landraces had, on average, 18% higher light‐saturating leaf CO 2 uptake (A sat) than the improved lines due to higher maximum apparent carboxylation rates of Rubisco carboxylation (V cmax) and regeneration of ribulose‐1,5‐biphosphate expressed as electron transport rate (J max). TME 419 also showed a greater intrinsic water use efficiency. Except for the cultivar TMS 30572, photosynthesis in cassava showed a triose phosphate utilization (TPU) limitation at high intercellular [CO 2]. The capacity for TPU in the leaf would not limit photosynthesis rates under current conditions, but without modification would be a barrier to increasing photosynthetic efficiency to levels predicted possible in this crop. The lower capacity of the lines improved through breeding, may perhaps reflect the predominant need, until now, in cassava breeding for improved disease and pest resistance. However, the availability today of equipment for high‐throughput screening of photosynthetic capacity provides a means to select for maintenance or improvement of photosynthetic capacity while also selecting for pest and disease resistance.

“…The result implies that cassava farmers in the study area were small scale farmers that cultivate less than one hectare of land. Small land holdings could present major constraint to technology adoption (Agwu, Njom, & Umeh, 2017). With respect to the level of education, majority (64.1%) of respondents had only completed elementary school, with a mean of 7 years of schooling.…”

The study assessed the food security status of poor households and contribution of cassava in their diets. Sixty-four cassava growers were selected from a Southeast Sulawesi cassava growing village using simple random sampling method. The United States Adult Food Security Survey Module was adopted in assessing the food security status of selected households. Data were analyzed qualitatively and using descriptive statistics. Results showed that a great majority (81.3%) of households were food secure. Average consumption of cassava based foods of 4.1 days a week compared to only 2.9 days for rice clearly confirmed that cassava was a dominant source of food and thus had contributed positively to the high food security status of households in the area. In view of its suitability with the farming and local food system as well as its importance in strengthening food security, efforts should be exerted to promote production, processing, marketing and consumption of cassava as staple food. 202affirmative. The questionnaire items were modified to a 30-day reference period rather than 12 month reference period (Coleman-Jensen et al., 2018).

Integration system is an effort to improve the welfare level of farmers. The objective of this study was to determine the welfare level of farmers as the implementers of integration system of rice and beef cattle. The research method was quantitative descriptive with samples of 25 farmers who applied integration system selected purposively. The data analysis used was the analysis of income and welfare level by using the approach of Southeast Sulawesi Provincial Minimum Wage (UMP) in 2019 and the poverty line of the farmers’ families. The results of the study were that the farmers who applied integration system of farming rice and beef cattle had different welfare level, in which 40% of farmers were classified as prosperous because their income from the integration system is greater than the UMP. Meanwhile, the remaining 60% farmers were classified as not prosperous because their income is smaller than the Southeast Sulawesi UMP and the average farmer was above the poverty line in the district of South Konawe
