Yellow Passion fruit performance in organic crop under mulch

Abstract

The aim of this work was to evaluate the effect of mulch on clay loam and sandy loam soils on the start harvest, number of fruits per plant, yield and quality of yellow passion fruits in organic crop. A complete randomized block design with five treatments and four replicates of five plants each was used. Treatments corresponded to different percentages of mulch of the area occupied by the plant (3 x 3 m), extending from the center of the planting line to the planting row in 0% without mulch (T1); 25% (T2); 50% (T3); 75% (T4) and 100% (T5). Mulch anticipated the harvest in comparison to crop in uncovered soil in both types of soil. The number of fruits per plant and yield increased in a quadratic function with maximum point of 38.6 fruits plant -1 and 5,182.0 kg ha -1 with 75.7% and 78.0% of soil cover, respectively. Mulch on clay loam soil did not provide increase in the average fruit mass and did not change the quality of fruits in relation to control fruits.

Desempenho do maracujazeiro-amarelo em cultivo orgânico sob cobertura mortaResumo -O objetivo deste trabalho foi avaliar o efeito da cobertura morta em solo franco-argiloso e franco-arenoso sobre o tempo necessário para início da produção, número de frutos por planta, produtividade e qualidade dos frutos do maracujazeiro-amarelo em cultivo orgânico. Utilizou-se o delineamento experimental de blocos inteiramente casualizados, com cinco tratamentos e quatro repetições de cinco plantas cada. Os tratamentos corresponderam a diferentes porcentagens de cobertura morta da área ocupada pela planta (3 x 3 m) se estendendo do centro da linha de plantio para a rua em 0% sem cobertura (T1); 25% (T2 ); 50% (T3); 75% (T4) e 100% (T5). A cobertura do solo foi aplicada em faixa contínua na linha de plantio. A cobertura morta antecipou a colheita dos frutos em comparação ao cultivo em solo descoberto, em ambos os solos. O número de frutos por planta e a produtividade aumentaram em função quadrática com ponto de máximo de 38,6 frutos/planta -1 e 5.182,0 kg ha -¹ com 75,7% e 78,0% de cobertura morta no solo, respectivamente. A cobertura morta no solo franco-argiloso não proporcionou incremento na massa média nem alterou a qualidade dos frutos em relação aos frutos provenientes da testemunha.

Organic compost as a conditioner of soils cultivated with yellow passion fruit

“…These values for the mean fruit mass in the organic system are similar to other studies Araújo Neto et al, 2009;Araújo Neto et al, 2014;Uchôa et al, 2018), being below the standard preferred in the country for table marketing, which is superior to 200 g (Araújo et al, 2012), even if the fruits from plants grown in sandy-loam soil present a superior mass to the national value, which is 120 g (IBGE, 2017). Uchôa et al (2018) found a fruit mass 18% higher in sandy-loam soil compared to the fruits produced in clay-loam soil.…”

“…In the state of Acre, several works developed with yellow passion fruit attest the positive aspects of organic agriculture, either in no-till systems with small planting rows (Araújo Neto et al, 2008), intercropped with pineapple, maize, cassava, and green manure (Araújo Neto et al, 2014), in coexistence with the stem borer (Rezende et al, 2017), grown using tall seedlings and with a long root system (Silva et al, 2019;Silva et al, 2020), or using mulch during the drought period in the region (Uchôa et al, 2018), contributing to the development of this production system.…”

“…In this context, the use of organic compost constitutes an alternative to increasing the production, yield, and economic profitability of the crop since, besides macro and micronutrients, the organic matter acts by improving the physical, chemical, and biological conditions of the soil (Alves et al, 2011;Araújo Neto et al, 2014;Uchôa et al, 2018).…”

Organic cultivation of yellow passion fruit using tall seedlings with long root systems

“…However, mean ratio values obtained by Uchôa et al (2018) in organic passion fruit were similar (p>0.05) to those found in this work.…”

“…The mean fruit mass of harvests 1 and 2 was not influenced by the length of the root system (Table 1), and the mean values are in accordance with the masses obtained for the organic cultivation in the region (Rezende et al, 2017;Uchôa et al, 2018). According to Dias et al (2017), for direct selling, the external appearance and the size of the fruit are the most evaluated attributes by the consumers.…”
