“…is a bromeliad that adapts well to semi-arid conditions (Franco et al, 2014). Also, the adoption of a fertilization program suited to the local conditions of cultivation is essential, because Brazilian soils do not supply the nutritional demand of pineapple plants (Guarocon & Ventura, 2011;Cardoso et al, 2013;Pegoraro et al 2014a).…”

Studies related to the absorption and exportation capacity of macronutrients by irrigated pineapple are essential for the definition of adequate doses and fertilization management. The objective of this study was to evaluate the accumulation of biomass and macronutrients in the compartments (leaves, shoot, root, seedlings/slip, crown/top, and fruit) of ‘Vitória’ pineapple irrigated in the semiarid region after the use of nitrogen doses and population densities. The treatments, arranged in randomized blocks with three replicates, arranged in a 5x4 factorial scheme, consisted of five nitrogen doses (0, 5, 10, 15 and 20 g per plant) and four population densities (51,282, 76,923, 90,909, and 126,984 plants ha-1). The accumulation of biomass and macronutrients in the pineapple compartments was evaluated at the end of the growing cycle. The increase of N doses combined with the increase of the plant population promoted a linear increase in the accumulation of biomass and macronutrients by the pineapple plants. The leaves presented greater accumulation of macronutrients, followed by the seedlings, shoot, fruit, crown, and roots. The pineapple presented the following decreasing order of macronutrient absorption: K> N> Ca> P> Mg>S. At the dose of 20 g per plant of N and population of 126,984 plants ha-1 were exported from the area by fruits, 1,311 (12%), 150 (9%), 144 (11%), 52 (11%), 46 (12%) and 36 (12%) kg ha-1 of K, N, Ca, P, Mg, and S, respectively; and by the shoots, 2,426 (22%), 480 (29%), 147 (11%), 101 (21%), 67 (18%), and 45 (15%) kg ha-1 of K, N, Ca, P, Mg, and S, respectively.

“…Maia et al (2020) descrevem apenas que estes nutrientes tem relação de antagonismo, já para a relação Ca/Mg, os mesmos autores propõem variação de 1:1 a 2:1 devido as necessidades específicas que as cultivares trazem em si. Pegoraro et al (2014) demonstraram que o abacaxizeiro de modo especial, o 'Vitória', possui uma alta demanda de magnésio e que a absorção de cálcio e magnésio é afetada pela disponibilidade no solo e fornecimento pela fertilização. Por fim, o nota-se também na tabela acima uma redução de 31% na relação Ca/Mn quando adotado o cultivo sob o mulching, no entanto os valores ideais dessa relação para o abacaxi ainda são pouco conhecidos, bem como a cobertura do solo pode interferir na absorção de ambos os elementos.…”

Estratégias de manejo agrícola podem melhorar a produção, especialmente em regiões com condições ambientais críticas para o desenvolvimento de culturas agrícolas, porém, em plantas como o abacaxizeiro, ainda carece de pesquisa aplicada para otimizar a produção e a qualidade dos frutos. Este trabalho, teve como objetivo avaliar o desenvolvimento das plantas e a qualidade dos frutos do abacaxizeiro das cultivares Pérola e Vitória, submetidas a dois métodos de cultivo (com e sem mulching) e dois tipos de capina (química e manual). O experimento foi conduzido na Região Norte do Espírito Santo, em delineamento de blocos casualizados, esquema fatorial triplo 2x2x2, onde avaliaram-se as cultivares Pérola e Vitória, inclusão ou não de mulching e realização da capina química ou manual. As plantas foram avaliadas quanto ao desenvolvimento vegetativo, teores de macro e micronutrientes e índice SPAD na folha D. Foram avaliadas a firmeza, massa, comprimento, diâmetro central e características físico-químicas. Nas condições edafoclimáticas do experimento, a cultivar Pérola teve crescimento mais rápido, porém teor de sólidos solúveis baixo (12º Brix) em relação à ‘Vitória’, apresentando-se indiferente em relação ao tipo de capina e mulching. Já a cv. Vitória produziu frutos com maior firmeza e teor de sólidos solúveis de 16 ºBrix, com importantes incrementos com o uso de mulching e capina manual, destacando-se nas características físico-químicas relacionado a qualidade dos frutos, o que leva a recomendar -se o uso destas técnicas para seu cultivo na região Litoral Norte do Espírito Santo.

“…The N and K uptakes by the maize were estimated from Bąk et al (2016). The N and K concentration in the dry matter and uptake by the pineapple fruit and residues were estimated from Pegoraro et al (2014). N and K uptakes by cassava were estimated from Howeler et al (2013).…”

Comparative analysis of nutritional status and growth of immature oil palm in various intercropping systems in southern Benin

et al. 2020

Beninese smallholders associate food crops and cash crops with immature oil palms to reduce field maintenance costs and gain income before the palms reach productive phase. Little is known about the effects of these crops on the nutritional status and growth of the palms in their immature phase even though the yield of adult palms can be affected by the management practices during this phase. The objective of this study was to evaluate the most common oil palm-based intercropping systems found in southern Benin in terms of nutritional status and growth of the palm. Within 15 oil palm farms, we compared 15 immature oil palm fields where the crop succession associated with the oil palms was dominated by maize, cassava, tomato, and pineapple. The nutrient concentrations in the soil and the palm leaves, and growth indicators were measured at the end of the immature phase. We found that the palm growth indicators were the lowest in the successions with pineapple. N and P nutrition of the immature palms was satisfactory but K was deficient in all systems, especially in those with pineapple. The K levels in the soils and palm leaves were correlated. Rough field budgets comparing the amounts of N and K applied to the crop successions with their N and K exports from non-returning products indicated that soil indigenous K supply would be particularly depleted in the systems with pineapple. We concluded that the young oil palms were affected by the competition for K exerted by the crop successions with pineapple even though they were the most fertilized in the region. The high profitable crop is therefore associated with the lowest growth rates of the immature palms. The mineral fertilizer management in these oil palm temporary intercropping systems should be improved.
