“…Accordingly, in this study, higher values in tuber number, length, and diameter gave higher tuber yield per hectare in variety "Hawassa-4," suggesting that increment of those yield components tends to increase yield per hectare. According to the result of Amarullah et al [40], the growth and yield parameter of cassava have some profound effect on the final tuber yield. In other ways, tuber yield was negatively correlated plant height, signifying that the tuber yield decreases when plant height gets higher (Table 4).…”

Since there is a variety of performance in cassava varieties for different agroecologies and there was no cassava production before in Ethiopian Somali regional state, Fafen district in particular. Investigation of the performance of higher tuber yielded cassava variety is the main concern for this study. Thus, the objective of this study was to evaluate tuber yield performance of cassava varieties. To do so, four varieties (kello, Qulle, Hawassa-4, and Chichu) were collected from Hawassa Agricultural Research Center and planted in Fafen district where there is arid climatic condition. Thirty-centimeter-long stakes were planted with 1 m × 1 m intra- and inter-row spacing with Randomized Complete Block Design (RCBD). There were four rows, five plants per row and twenty plants per plot. Phenological, growth, and agronomic parameters were analyzed using SAS software; mean differences were compared using LSD at p≤0.05. The result revealed that days to 50% establishment of the stem cuttings of variety “Qulle” were performed within 15.6 days. Among all varieties, Chichu and Hawassa-4 had the highest number of plant stand count, 88.3 and 86.7%, respectively. The highest number of mean multiplication ratio, secondary branches per plant, and mean plant height were obtained with variety “Qulle.” With regards to tuber yield and its components, there was significant difference among understudied cassava varieties. The highest tuber yield (23.93 t/ha) was registered in variety “Hawassa-4” followed by Kello (19.90 t/ha) and Qulle (18.73 t/ha). It implies that variety “Hawassa-4” performed best in the test area and hence recommended in test area.

“…One that affects plant growth and production is seeds with the best quality because it will affect the roots of cassava plants (Legese et al, 2011;Amarullah et al, 2016). Figure 7 shows root growth in seedlings cut using a petokong machine, saw and machete.…”

Preparation of cassava seeds using a machete or hand saw takes a long time, the results are not uniform, and there is a potential for damage to cassava seedlings. The double block cutter type cassava stem cutting machine has been designed to produce high capacity and good quality cassava seeds. This study aims to test the performance of the cassava stem cutting machine with the double block cutter type. Performance tests include measuring machine working capacity, fuel consumption, seed uniformity, and planting test. The cutting test was carried out using 3 varieties of cassava seedlings. The machine works at a rotational speed of 3800 rpm and the test was carried out with various feeding loads, namely 3 rods, 4 rods, and 5 rods with. Each test was repeated 3 times. Cassava stem cutting machine (Petokong) is suitable for producing cassava stems with an average working capacity of 16275 seeds/hour. The results of the Anova test showed that the number of baits and varieties of cassava seeds and their interaction had a significant effect on the working capacity of the Petokong machine. Variations in fuel consumption are thought to be influenced by the variety of cassava stem used, which is influenced by the stem diameter of each variety. The Petokong machine is far superior to manual cutting using a machete or saw which can only produce 815 and 3005 seeds/hour per hour. The average fuel consumption is 1.82 liters per hour. Seed uniformity is about 98% and seedling damage can be minimized to 2%. The seeds produced by the Petokong machine can grow well, which is indicated by the appearance of shoots and an even distribution of roots.

“…Meanwhile, at 4-8 WAT and 8-12 WAT, SLA had a significant positive correlation with production 0.347 and 0.747, respectively). A study by Amarullah et al [60] concluded that the initial vegetative growth phase was associated with a high assimilation rate for root formation, while the optimum vegetative growth phase significantly affected final yield.…”

“…e surplus carbon is used for leaf thickening and leaf area growth and for promoting further plant growth depending on the plant's developmental phase. Previous research has shown that plant development influences optimal production in the early growth phase and the maximum vegetative phase and depends on the variety used [60].…”

This study aimed to examine plant growth of tomato grafted onto different eggplant rootstocks. We applied a randomized block design comprising twelve treatments with three replicates. Three varieties of tomato—Cervo, Karina, and Timoty—and three rootstocks—Gelatik, EG203 line, and Solanum torvum—were selected for this study. Nongrafted tomato plants of the same varieties were used as controls. The variables recorded were the number of branches, the diameter of scions and rootstocks, root length, and root dry weight at 4, 6, 8, and 10 weeks after planting (WAT) and relative growth rate, specific leaf area, and net assimilation rate at 4, 8, and 12 WAT. Grafted tomato plants demonstrated better growth than controls. There was a significant relationship between yield, plant growth parameters, and photosynthetic organs, expressed by higher production, greater scion diameter, longer roots, and increased relative growth rate, leaf area ratio, and net assimilation rate of grafted plants, compared to the controls.
