Performance of cassava (Manihot esculanta. Cratz) clones in potential and low moisture stressed areas of Ethiopia

Abstract

and Kello (standard check) were evaluated by using randomized complete block design replicated three times. The evaluation was carried out for two consecutive years, from 2012 to 2014. The combined analysis result indicated that there was statistically significant difference among the clones tested and the locations where the experiment was conducted. The clone AWC-1 (37.17 t/ha) followed by AWC-2(35.52 t/ha) and AWC-5 (35.51 t/ha) gave the highest storage root yield but there was no statistically significant difference in the total storage yield among the clones AWC-2, AWC-3 and AWC-5. In the same way, the highest dry matter content was recorded from the clones AWC-2 (51.8%), AWC-3 (48.5%) and Kello (49.1%). Among the locations tested, the best result was obtained from Amaro (35.14 t/ha) which is characterized by its low moisture stress, indicating that cassava can resist/tolerate low moisture stress and give comparative yield provided that other factors are not limited. Thus, those clones with the highest storage root yield and dry matter content were promoted for variety verification and will be released for wider production.

Evaluation of Cassava Genotypes for Agronomic Performance, Correlation with CMD and CBSD Parameters and Stability across Alupe, Kakamega and Kibos in Western Kenya

“…World-wide, cassava is a staple food for more than 800 million people [4]. However, agronomic performance of cassava is increasingly constrained by the two principal biotic constraints, cassava mosaic disease (CMD), caused by cassava mosaic geminiviruses (CMGs) and cassava brown streak disease (CBSD), caused by cassava brown streak viruses (CBSVs) [3,[5][6][7]. In Africa, yields are only 8-10 tonnes per hectare, on average approximately half of those achieved in Asia and Latin America [8].…”

Evaluation of Cassava (<i>Manihot esculenta</i> Crantz) Genotypes for Total Cyanide Content, Storage Tuber and Starch Yield in South Western Ethiopia

“…The result of this study is similar with the report of [28] who reported cassava genotypes collected from southwest Ethiopia had significant difference in storage tuber yield and related traits. Similarly, [26] also reported high significant (p<0.01) difference among cassava genotypes tested at Hawassa, Amaro, Jima and Sekota areas of Ethiopia. The storage tuber length is also vary significantly (p<0.05) among tested cassava genotypes.…”

“…This result is supported by the report of [29], who reported the storage tuber length of cassava grown in clay soil and high moisture stress areas of southern Ethiopia are reduced significantly. Besides, [26] reported variety Kello produced longest mean storage tuber of 40.67 cm grown in major growing areas of Ethiopia. However, in this study the storage tuber length obtained from Jimma (48.90) and Metu (53.10 cm) is higher than the report of [26].…”

“…Studies of nutritional composition on cassava as a food are considerable significance since it may help to identify long forgotten food resource [27]. In this regards, few attempt was made to understand the proximate composition and anti-nutritional factors of the underutilized tubers of cassava to make edible tubers as the safe food sources for mass consumption [26]. In contrast to cultivated tubers, little is known about the proximate composition and reasons to expect that some of the species differ in composition from common varieties.…”
