“…Regarding the variables stem, leaf and total dry masses, the absence of difference for the stem occurred due to the short evaluation time of the experiment, because certain trends of the results that have not yet become significant were observed. Bataglia et al (1999) when evaluating the effect of N, P and K fertilization on rubber trees, verified the first significant responses in plant growth at 24 months after planting.…”

“…In relation to stem diameter, absence of significant interactions between N, P and K doses was also verified by Bataglia et al (1999), who evaluated rubber tree plants after 12 months of planting and found no differences for this variable under increasing doses of P and K. It can be inferred that this situation occurred in both studies because this variable only begins to show a significant response after 24 months of age, or just over a year after the beginning of fertilizer applications.…”

The objective of this study was to evaluate the growth, root and shoot dry mass accumulation and nutritional status of rubber tree in the initial stage of cultivation, under different combinations of nitrogen (N), phosphorus (P) and potassium (K). Combinations of the following doses were tested: 0, 20, 40 and 80 kg ha-1 of N; 0, 75, 150 and 300 kg ha-1 of P2O5; and 0, 25, 50 and 100 kg of K2O. Under the soil and climate conditions analyzed, the combinations of NPK fertilization applied at planting only caused significant growth responses of rubber tree plants as a function of the absence of N and its presence at the dose of 80 kg ha-1. Through leaf analysis it was possible to verify that N fertilization and P fertilization are adequately meeting the needs of rubber tree plants, while the K doses tested did not reach the adequate levels of sufficiency.

“…Bataglia et al (1998), na mesma classe de solo, observaram efeitos significativos das adubações nitrogenadas e fosfatadas no perímetro do caule e das adubações nitrogenadas e potássicas na porcentagem de plantas aptas à sangria. Resultados semelhantes foram obtidos por Bataglia et al (1999) em seringais, em solo Podzólico Vermelho-Amarelo eutrófico, em Matão, SP, ressaltando não só a importância do K na nutrição da seringueira, como também no equilíbrio entre o N, o P e o K.…”

“…Entretanto, nas áreas não tradicionais, a análise de solo e o diagnóstico foliar têm sido utilizados na avaliação e acompanhamento de programas de adubação, possibilitando um significativo retorno e melhoria da qualidade das recomendações (Bataglia et al, 1999).…”

O objetivo deste trabalho foi avaliar o estado nutricional de seringais implantados na Zona da Mata, em Minas Gerais, visando contribuir com um programa racional de adubações. Em seringais do clone IAN 873 foram determinadas a classe do solo, fertilidade, nutrição e produção de borracha seca. Grande parte dos seringais encontra-se em Latossolos extremamente ácidos com Al alto e N, P, K, soma de bases trocáveis e capacidade de troca de cátions baixos. Os teores de Ca e Mg variaram de médios a altos nos Latossolos e foram muito altos nos Nitossolos, correlacionando-se negativamente com a produção de borracha seca. A análise foliar detectou desequilíbrios nutricionais no que se refere aos baixos teores de N e K evidenciados pela correlação positiva significativa com a produção de borracha seca. A correlação significativa negativa entre a produção de borracha seca e os teores de Ca foliares, associados aos altos teores de Mg, sugerem a redução desses nutrientes nas adubações. Dos micronutrientes, apenas o Cu apresentou correlação positiva e significativa com a produção de borracha seca.

The rapid expansion of rubber tree plantations in recent decades has been accompanied by dramatic negative ecological and social impacts. Rubber sector stakeholders consequently engaged in sustainable production of rubber. Despite the lack of harvest during the immature stage following planting, this period plays a key role in future yields. Management practices, particularly fertilization regimes, are used by farmers to shorten the immature period as much as possible. This entails maintaining or even improving the productivity of existing plantations to face the demand for natural rubber. This review focuses specifically on the immature period of rubber tree plantations, as it is the most critical period for nutrient management. We reviewed available knowledge on fertilization practices, soil management, and nutrient dynamics in rubber plantations with the goal of developing a nutrient balance approach for this crop. Our review revealed (1) a notable difference between fertilizer recommendations made by technical institutes and those reported in the scientific literature; (2) that even though nutrient diagnostic methods could help growers adapt the fertilization of rubber trees more than 3 years of age, further studies are needed to adapt current methods to the wide range of cultivation areas; and (3) that the nutrient budget approach may be the best way to incorporate the variety of rubber tree cultivation conditions. In conclusion, the nutrient budget method is a promising way to improve the sustainability of rubber plantations through fertilization making it possible to increase nutrient use efficiency. A comprehensive approach based on nutrient budgets requires further in-depth studies to examine nutrient dynamics in a wide range of conditions, including intercropping and logging residue management between clearcutting and replanting.
