'Tommy Atkins' mango trees subjected to high density planting in subhumid tropical climate in northeastern Brazil

Abstract

-The objective of this work was to evaluate the effects of high density planting on 'Tommy Atkins' mango trees cultivated in subhumid warm tropical climate in northeastern Brazil. Treatments consisted of five spacial arrangements of plants (8x5 m, 7x4 m, 6x3 m, 5x2 m and 4x2 m), which resulted in the following plant densities: 250 (control), 357, 555, 1,000 and 1,250 plants per hectare. Plant vegetative and reproductive variables, besides fruit quality parameters, were evaluated at seven and eight years after transplantation to the field. In general, high density planting caused reduction in vegetative and reproductive variables of individual mango trees, but had little influence on fruit quality. Above 555 plants per hectare, a significant decrease was observed in mango tree growth. Furthermore, there were decreases in the percentage of flowering, fruit yield per plant and per area. However, planting density up to 357 plants per hectare, in spite of decreasing plant growth and fruit yield per tree, increases fruit yield per area in 30% in comparison to the control.Index terms: Mangifera indica, fruit yield, high density orchard. Mangueiras 'Tommy Atkins' submetidas à alta densidade de plantio em condições de clima tropical subúmido no Nordeste do BrasilResumo -O objetivo deste trabalho foi avaliar os efeitos do adensamento de plantio sobre mangueiras 'Tommy Atkins', sob condições de clima tropical quente subúmido, no Nordeste do Brasil. Os tratamentos consistiram de cinco arranjos espaciais de plantas (8x5 m, 7x4 m, 6x3 m, 5x2 m e 4x2 m), que resultaram nas seguintes densidades de plantio: 250 (controle), 357, 555, 1.000 e 1.250 plantas por hectare. Variáveis vegetativas e reprodutivas das plantas, além de parâmetros de qualidade dos frutos, foram avaliadas no sétimo e no oitavo ano após a implantação do pomar no campo. Em geral, o adensamento populacional causou redução nas dimensões individuais das variáveis vegetativas e reprodutivas das plantas, com pouca influência sobre a qualidade dos frutos. A partir de 555 plantas por hectare, observou-se diminuição significativa do crescimento das plantas de manga. Além disso, houve redução da percentagem de florescimento, da produção de frutos por planta e por área. Entretanto, o adensamento até 357 plantas por hectare, apesar de reduzir o crescimento das plantas e a produção de frutos por planta, aumenta em 30% a produção de frutos por área, em comparação ao controle.Termos para indexação: Mangifera indica, produção de frutos, pomar adensado.

Growth and Flowering of Five Mango Cultivar under Subtropics Conditions of Brazil

“…In this context, the producers seek varieties with higher productivity, yield stability, easy handling in cultivation, adapted to adverse climate conditions where it will be developed. The distributors need varieties with greater resistance to handling and transport, while consumers seek the best quality fruits, with emphasis on the color and flavor [6,7].…”

Effect of Planting Density and Mulching on Vegetative and Reproductive Parameters of Mango (Mangifera indica L.) cv. Alphonso

“…Consequently, there were reductions in the number and yield of fruits per plant. In the planting densities of 400 and 267 plants per hectare, the number of fruits produced represented only about ¼ of those produced in the lowest planting density, with 267 plants per hectare in mango (Sousa et al, 2012). In the field, stimulation of above ground growth due to mulch might be brought about by warming of the stem by air escaping from the planting hole in the mulch.…”

An overview of canopy management in cashew (Anacardium occidentale L.)

“…In recent times, there is a shift in farmers' perception from production to productivity and profitability which can be achieved through accommodating a greater number of plants per unit area. Studies on high density planting systems in fruit crops such as guava, mango and cashew have been shown to be more economical compared to the traditional planting system (Yadukumar et al, 2001, Bal and Dhaliwal 2003, Sousa et al, 2012, Gaikwad et al (2017.…”
