“…A menor produção de MS da beterraba quando não houve adubação com K pode ser atribuída aos prejuízos na taxa de fotossíntese e atividade de enzimas relacionadas ao transporte de sacarose (Diaz-Medina et al, 2016). Fornecimento equilibrado de K em beterrabas em condições adversas de estresse salino melhora o conteúdo da matéria seca total (Abbas & Al-Jbawi, 2019). Por isso, as concentrações adequadas de K disponível no solo agrícola melhora a eficiência do uso de água pela cultura da beterraba, aumenta a tolerância ao estresse e melhora os rendimentos da planta (Jákli et al, 2018).…”

Objetivou-se com esta pesquisa avaliar a produção da beterraba de mesa (Beta vulgaris) em função da fonte de potássio. O experimento foi conduzido na Universidade Federal de Viçosa -Campus Rio Paranaíba -MG. Dois experimentos, conduzidos nas épocas de verão e de inverno e com a mesma matriz experimental, consistiram da combinação de fontes e de doses de K. As fontes estudadas foram o cloreto de potássio, o sulfato de potássio e o nitrato de potássio. As doses de K foram de 60, 120 e de 240 mg/dm³ de K.

Two field experiments were conducted in Senouris; Tamya Res. Station, Fayoum Governorate, Egypt (latitude of 30.82 o N and longitude of 29.40 o E) during the two successive seasons of 2017/2018 and 2018/2019, to evaluate the performance of three sugar beet varieties (Alauda, Nefirtitis and Carnuta), sown using three spaces between hills (15, 20 and 25 cm) under conditions of loamy (saline soil) and silt-clay soils, in two separate field experiments on yield and quality. Under each soil condition; the experimental design was a split-plot with three replications. Collected data were analyzed combined over the two locations in each season. Hill spaces were allocated in the main plots, whereas, varieties were randomly distributed in the sub-plots. Results showed a positive statistical response in root length and diameter, as well as, root fresh weight/plant, root and sugar yields/fad, when sugar beet plants were sown under silt-clay soil, compared to saline soil (loamy texture) conditions. Meanwhile, the highest K and Na contents and sucrose% were obtained under saline soil conditions, in both seasons. Root dimensions, root fresh weight/plant, root and sugar yields/fad positively and continuously responded to increasing hill spaces up to 25 cm. However, the insignificant differences among sowing hills were found in K, Na and alpha-amino N contents, sucrose% and purity%, in both seasons. The examined varieties differed significantly in root diameter and root fresh weight/plant, in both seasons, as well as, root length only in the 1 st season, and root yield/fad in the 2 nd one. The heaviest roots were obtained from Carnuta variety and superiority over the other tested varieties. The significant differences among sugar beet varieties in sugar yield/fad were showed only in the 2 nd season, meantime, the differences among varieties were insignificant in K, Na, alpha-amino N contents, sucrose% and purity%, in both seasons. The highest sugar yield/fad was obtained from Carnuta variety, followed by Alauda, while the least sugar yield/fad resulted from Nefirtitis variety, in the 2 nd season. The interaction between soil types and hill spaces showed significant effects on root diameter in both seasons and sugar yield/fad only in the 2 nd season. Carnuta variety recorded the highest. Significant values of root length under siltclay soil conditions, in the 1 st season. The significant interaction between hill spaces and varieties was reflected in purity% in the 2 nd season. Alauda achieved the highest purity% at 15 and 25 cm between hills, meantime, Nefirtitis gave the best purity% at 20cm between hills. The 2 nd order interaction, among the three factors under study had a significant influence on sucrose% only in the 2 nd season. The highest sucrose% was attained from the interaction between varieties and distances between hills under saline soil (loamy texture) than silt-clay soil conditions. Based upon the obtained results, it was found that sowing Carnuta variety at 25cm between hills might be recommended to achieved the hi...
