“…Because zeolite and organic fertilizer can reduce plant nutrient leaching better than pumice according to their higher CEC (Panuccio et al, 2009;Duangpatra, 2010), therefore, cassava can uptake plant nutrient and accumulated in fresh tuber better. Higher accumulation of K were detected because cassava could accumulate highest K in tuber, followed by total N and P respectively, which corresponded with previous reports (Howeler & Cadavid, 1983;Howeler, 1991). …”

“…Levels of available P in soil were found between low to moderate but level of exchangeable K in soil is still very low due to leaching in coarse-textured soil and crop removal according to previous reports that consistently suggested that cassava drawn large amount of K from soil. The content of P was not greatly affected by the treatments (Howeler & Cadavid, 1983;Howeler, 1991;Kongkaew, 2007). Moreover, chemical fertilizer combined with organic fertilizer rate 1,018.75 kg ha -1 resulted highest available P and exchangeable K in soil followed by chemical fertilizer 100% combined with zeolite and pumice respectively.…”

This study was conducted to determine the effect of fertilizer management in combination with soil conditioner (zeolite, pumice and organic fertilizer) on yield of cassava var. Huay Bong 60 cultivated on coarse-textured soil in Thailand. The experiment was arranged in a randomized complete block design. The results revealed that addition of chemical fertilizer combined with organic fertilizer rate 1,018.75 kg ha -1 gave the highest plant height, above ground biomass, fresh tuber yield, starch content, starch yield and concentration of primary nutrient in fresh tuber yield and were not difference from addition of 100% chemical fertilizer combined with zeolite rate 312.5 kg ha -1

“…Howeler and Cadavid (1983), Boerboom (1978) and Islam et al (2008) also noted genetic variation for DM in different cassava accessions. Mean DM content was greater in tuber (41.53%) than stem (30.19%), petiole (27.55%), leaf lobe (24.69%) and peel (21.83%) ( Table 1).…”

Cassava (Manihot esculenta Crantz) roots (tubers) are used as staple food. Starch extracted from tubers is widely utilized as raw materials in industries. Dry matter (DM) content, starch and flour extraction and proximate composition were investigated in seven cassava accessions (Coc-A 1, Kh-A 2, Cow-A 3, Sa-A 4, Me-A 5, Va-A 6 and Sy-A 8. ) in 2010-2011. Leaf DM varied from 20.51% in Me-A 5 to 29.01% in Sy-A 8 ; that of stem from 27.24% in Va-A 6 to 32.10% (average of Sy-A 8 , Me-A 5 and Sa-A 4 ); and that of tuber from 37.30% in Kh-A 2 to 45.26% in Sy-A 8 . Starch was extracted by blending chopped tuber followed by decantation. Tubers were sliced, sun dried and milled into flour. Tuber starch content (fresh wt. basis) varied between 15.04% in Sy-A 8 and 24.97% (average of Coc-A 1 and Me-A 5 ); that of peel from 4.54% in Va-A 6 to 5.85% in Coc-A 1 . Crude protein varied from 1.80% (average of Kh-A 2 , Cow-A 3 and Sy-A 8 ) to 4.53% in Va-A 6 . Crude fiber content varied from 1.95% (average of Sa-A 4 and Coc-A 1 ) to 4.27% in Cow-A 3 . Cyanogens present in cassava plant escape as hydrogen cyanide (HCN) during harvesting and processing. Variation for HCN existed and it was 140.95 mg/kg fresh tuber (average of Sy-A 8 and Coc-A 1 ) to 546.0 mg/kg fresh tuber in Va-A 6 . There was no detectable HCN in the extracted flour and starch. It may be concluded that genetic variation for DM, starch, protein and HCN existed in seven cassava accessions, and Coc-A 1 may be a better one due to its lower HCN, higher DM and starch content.

“…Ao final do cultivo, a quantidade acumulada de Cu nas raízes respondia por quase metade do total acumulado na planta. O mesmo comportamento no padrão de distribuição do referido micronutriente foi observado por Howeler & Cadavid (1983), que relataram quantidade superior de Cu na parte aérea até os 8 meses de cultivo, e, a partir de então, maior acúmulo nas raízes.…”

“…As plantas de mandioca, ao final do ciclo de cultivo, acumularam 182 g ha -1 de Mn. Howeler & Cadavid (1983) verificaram acú-mulo de Mn inferior ao encontrado nesta pesquisa, atestando, inclusive, diminuição de sua quantidade, ao final do ciclo de cultivo. Constataram acentuada variação no teor do nutriente ao longo do crescimento da mandioca, confirmando o relato de Mukhopadhyay & Sharma (1991), sobre a abundante flutuação nutricional para Mn, nos tecidos das plantas.…”

INTRODUÇÃOA mandioca é uma espécie perene, de propagação vegetativa e origem sul-americana, pertencente à família Euphorbiaceae, cultivada em todas as regiões do território nacional, sob diversas condições edafoclimáticas. Caracterizada pela produção de raízes e fécula, apresenta importância socioeconômica na região dos trópicos, sendo utilizada como fonte alimentar para humanos e animais, além da produção ABSTRACT RESUMOde energia renovável (Rós et al. 2011, Odubanjo et al. 2011. A determinação do requerimento de nutrientes pelas plantas deve ser feita por meio do conhecimento da curva de crescimento e de absorção de nutrientes pelos órgãos da planta, nas várias fases de desenvolvimento, dentro do ciclo de cultivo. A análise química dos órgãos vegetais é uma ferramenta que permite a avaliação do estado nutricional da planta, identificando a produtividade das culturas, em função Dry matter and micronutrients accumulation in cassava intercropped with banana treeCassava is an important intercropping plant. However, there is little information on its dry matter accumulation and partitioning, as well as micronutrient demand, when it is intercropped with fruit trees. The study was conducted in Januária, Minas Gerais State, Brazil, in 2010-2011, aiming at evaluating the dry matter and micronutrients accumulation in cassava intercropped with irrigated banana tree. A randomized blocks design, with four replications, was used, with treatments consisting of 14 sampling periods, from sowing to harvest. At each sampling period, plants were classified as shoots (stems and leaves) and roots, for determining their dry matter and contents of Cu, Fe, Mn and Zn. The dry matter and micronutrients accumulation fitted a sigmoidal growth pattern. The shoot dry matter accumulation increased up to 200 days after planting (DAP), stabilizing thereafter up to the end of the crop cycle. For roots, the dry matter accumulation was continuous up to the end of the cycle. From 250 DAP, roots became the main dry matter accumulation organ. Micronutrients accumulation in cassava plants occured in the following order: Fe > Zn > Mn > Cu. It was concluded that the cultivation of cassava intercropped with banana tree is viable, provided there is a proper availability of micronutrients required by plants.
