“…Of all nutrients, K was the most absorbed by the potato plant corroborating data published by Cabalceta et al (2005), Horneck andRosen (2008), andFernandes (2010). Yorinori (2003) verified K to be more absorbed than N during the rainy season and the opposite during the dry season.…”

“…Yorinori (2003) showed that the total P accumulated in the plants (leaves, stems, and tubers) of the 'Atlantis' cultivar were 422.9 mg plant -1 during the rainy season and 366.3 mg plant -1 during the dry season these values being lower than the one found in this work (504.2 mg plant -1 ) at 90 DAP when leaves and stems had not dried up. Data published by Fernandes (2010) show that, at 97 DAP, plants of the 'Agata', 'Atlantic', and 'Markies' cultivars had accumulated a total of 392 mg plant -1 and those of the cultivars 'Asterix' and 'Mondial' of 504 mg plant -1 , a value close to the one we found in this investigation (504.2 mg plant -1 ) at 90 DAP. The P value reported by Heard (2004), such as was the case of N, is larger (1277 mg plant -1 ) than the one found in this work.…”

“…5, No. 7;2013 dry matter allocated to the tubers vary between 69 and 90% of the plant total (Alvarez-Sánchez et al, 1999;Aguilar et al, 2001;Alva et al, 2002;Yorinori, 2003;Mora-Aguilar et al, 2005;Sharifi et al, 2005;Geremew et al, 2007;Horneck & Rosen, 2008;Ñústez et al, 2009;Fernandes, 2010). This variation may be explained by genotype effect, cultivation time, environmental factors specially temperature and photoperiod, soil fertilization and the level of senescence of the plant aerial part at the moment the sample was taken.…”

The objective of this research work was to quantify both the development of potato plants of the 'Asterix' cultivar and the accumulation of nutrients by the plants. The experiment was carried out at Perdizes, state of Minas Gerais, Brazil, in a randomized complete block design with seven treatments (sampling moments) and three replications. The spatial arrangement of the plants in the field was of 0.80 m between rows and 0.35 m between plants in the row. Plant samples were taken 30, 42, 54, 66, 78, 90, and 114 days after planting (DAP) for the determinations of plant dry matter and accumulated nutrients. The potato plant was slow to grow up to 42 DAP and the highest rate of dry matter accumulation was observed between 51 and 90 DAP. Plant cycle was of 97 days and total productivity of 44 t ha -1 . Total macro nutrients accumulated by the plants up to 90 DAP were of 369.3, 184.0, 42.7, 18.0, 16.2, and 13.8 kg ha -1 of K, N, Ca, P, Mg, and S, respectively. The micronutrients Fe, Mn, Zn, B, and Cu were found to have reached values of 1,225, 525, 439, 164, and 96 g ha -1 , respectively.

O objetivo deste trabalho foi caracterizar química e fisicamente batatas cultivadas sob diferentes doses e fracionamentos de nitrogênio e potássio. Foram utilizadas três doses de N e K (75% da dose recomendada; dose recomendada de acordo com a análise do solo e 125% da dose recomendada) e cinco épocas de aplicação (100% no plantio; 1/3 no plantio e 2/3 na tuberização; 50% no plantio e 50% na tuberização; 1/3 no plantio, 1/3 na tuberização e 1/3 25 dias após a tuberização; 1/4 no plantio, 1/4 na tuberização, 1/4 25 dias após a tuberização e 1/4 50 dias após a tuberização). O delineamento experimental utilizado foi o de blocos ao acaso, em esquema fatorial 5 × 3, com quatro repetições. Foram utilizados tubérculos da cultivar Ágata, uniformemente brotados. As características avaliadas foram: firmeza, pH, sólidos solúveis, acidez total titulável, açúcares redutores e açúcares totais. Os dados foram submetidos à análise de variância e teste Tukey, a 5% de probabilidade. Apenas o uso do fracionamento de N e K influenciou no teor de açúcares redutores.

ArtigosCrescimento e partição de massa seca em plantas jovens de amburana (Amburana cearensis (Fr. All.) AC Smith) e de umbuzeiro (Spondias tuberosa Arr. Cam.) 1Growth and split of the dry mass in young plants of amburana (Amburana cearensis (Fr. All.) AC Smith) and umbuzeiro (Spondias tuberosa Arr. Cam.) ResumoAs espécies amburana (Amburana cearensis (Fr. All.) A. C. Smith) e o umbuzeiro (Spondias tuberosa Arr. Cam.) possuem adaptações fisiológicas e morfológicas às condições climáticas do bioma caatinga e atualmente estão sob ameaça de extinção. Objetivou-se com a realização deste trabalho caracterizar a partição de fotoassimilados das mudas de Amburana cearenses e Spondias tuberosa buscando compreender a contribuição do sistema radicular tuberoso para a manutenção do crescimento inicial das mesmas. O estudo foi realizado na Unidade Experimental Horto Florestal da UEFS, o experimento foi disposto em delineamento em blocos casualizados, com quatro intervalos de avaliação após o transplantio das mudas (DAT) (60; 120; 180 e 240 dias). Foram avaliados os parâmetros: altura da planta, diâmetro do caule, comprimento e largura de folha e raízes tuberosas, número de folhas, área foliar e massa seca. Com base nos dados de massa seca e área foliar, foram realizados os cálculos de taxa de crescimento absoluto (TCA), taxa de crescimento relativo (TCR), taxa assimilatória líquida (TAL), razão de área foliar (RAF), área foliar específica (AFE), razão de peso foliar (RPF) e peso específico da folha (PEF). Em ambas as espécies, a partição de fotoassimilados indica que inicialmente a raiz tuberosa funciona como um dreno de alta atividade, até a finalização da sua formação, seguindo de ramos, raízes secundárias e folhas. Para grande parte dos parâmetros de crescimento, as plantas de Spondias tuberosa obtiveram médias notoriamente mais altas, assim, consequentemente, obteve maior crescimento e desenvolvimento que as mudas de Amburana cearensis. Conclui-se que a formação das raízes tuberosas ocasiona interferência no crescimento inicial das plantas de ambas as espécies. AbstractAmburana cearensis and Spondias tuberosa have physiological and morphological adaptations for the climate of caatinga biome and are under threat of extinction. The objective of this paper was to characterize the photoassimilate partition of Ambulana cearenses and Spondias tuberosa plants trying to understand the contribution of the root system to the maintenance of the initial growth of the plants. The experiment was arranged in a randomized block design, with four evaluation intervals after the transplanting of the seedlings (60, 120, 180 and 240 days). The parameters analyzed were: plant height, stem diameter, length and width of leaf, number of leaves, leaf area, tuberous roots and dry mass. From the dry mass data and total leaf area,
