Yield and Quality Response of Cassava (Manihot esculenta Crantz) to Nitrogen and Potassium Fertilizer Rates at Arba Minch, Southern Ethiopia
<p><em>Cassava (Manihot esculenta Crentz), is a major staple food crop of the people in most parts of Africa, and plays an important role in terms of food security, employment and income generation for farm families. It is one of important root crops in Ethiopian diet; however there is no research work has been done on rate of nitrogen and potassium fertilizer. Rate of N and K fertilizer are the major factor in determining the quality and quantities of cassava. Thus, this experiment was carried on the influence </em><em>of nitrogen and potassium</em><em> fertilizer rate on yield and qualities of </em><em>cassava </em><em>at Arba Minch. Four levels of N (0, 46, 92 and 138 kg N ha<sup>−1</sup>) and three levels of K (0, 60, and 120 kg K ha<sup>−1</sup>) were arranged in factorial combination in a randomized complete block design (RCBD) with three replications. The results revealed that the main effects of nitrogen fertilizer rates influences all the studied parameters, while the main effect of potassium affects number of tubers per plant and tuber diameter. Interaction effect of N and K influences fresh tuber yield of cassava. The highest fresh tuber yield of cassava was achieved from the combination of 92 kg Nha<sup>-1</sup> with application of 0 kg K ha<sup>−1</sup>, whereas the lowest fresh tuber yield of cassava was obtained from the combination of 0 kg N ha<sup>−1</sup> with 0 kg K ha<sup>−1</sup>. The economic analysis showed that higher net benefit and marginal rate of return were obtained from the application of 92 kg N ha<sup>−1</sup> with 0 kg K ha<sup>−1</sup>. In order to prevent excessive production costs, the use of 92 kg Nha<sup>-1</sup> combined with the application of 0 kg K ha<sup>−1</sup> is recommended. </em></p>
Quantitative assessment of trace and macro element compositions of Cassava (Manihot esculenta) storage roots enriched with Β-Carotene as influenced by genotypes and growing locations
Cassava's important mineral contents depends on some factors, including genetic and growing locational factors. The study aimed to evaluate the influence of genotype and growing locations on the mineral concentrations in yellow-fleshed cassava root genotypes. Twenty-five pipeline yellow-fleshed cassava genotypes and three white-fleshed varieties (check samples) were planted at five different experimental fields for two seasons, each representing the major agroecological zones in Nigeria. Standard laboratory protocols were employed in the sampling to ensure zero contamination, and the trace and macro elements were determined using the inductively coupled plasma optical emission spectroscopic method (ICPOES). The trace and macro elements identified in all the genotypes and varieties investigated were Fe, Mn, B, Cu, Mo, Co, Ni, Zn, and Al; Ca, Mg, Na, K. P, and S respectively. Genotype and growing location had a highly significant (p < 0.05) effect on all the trace elements except Ti and Cr. However, there was no interactive effect between genotype and growing location on all the trace elements except for Pb and Zn. Among the explanatory variables, the variable growing location was the most influential on macro and trace elements. Conclusively, genotypes 01/1442 and 01/1273 have outstanding trace and macro element concentrations.
