“…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.…”

“…In spite of the high level of annual rainfall in the state, its distribution is uneven (INMET, 2017). In the drought period, there is a shortage of water and low productivity (Araújo Neto et al, 2009;Rezende et al, 2017;.…”

“…The planting groves were fertilized with 500 g of limestone and 200 g of Yoorin ® (thermophosphate).Plague control was performed according to the legislation on organic vegetal production, with preventive applications of a microbial insecticidal based on Bacillus thuringiensis, specifically for leaf-feeding Caterpillars (Dione juno juno and Agraulis vanilae vanilae), and neem oil at 1%. For the control of curculionids (Philonis passiflorae), a mixture of 1% neem oil + 4% of a sulfurbased broth was inserted in the stem hole with the aid of syringes, followed by recovery grafting in plants with severe damage levels, according to the methodology proposed byRezende et al (2017).Periodic mowing interventions were performedalong with the crowning of the plants every 60 days for the control of spontaneous weeds. The harvests were performed twice a week, collecting fallen fruits on the ground and those with 50% of husk coloration.The plant height (cm) and the base diameter (mm) were evaluated at 120 days with the aid of a measuring tape and a digital pachymeter with a precision of 0.01 mm, respectively.…”

Studies related to adaptation to the environment and different conditions of water availability contribute to decision-making regarding the management of any crop to be implanted. Accordingly, this work aimed to evaluate the yield and quality of organic yellow passion fruit cultivated in a long root system in dryland conditions. The experimental design was in randomized blocks, with five treatments and four replications with four plants each. The treatments consisted of the alteration of the length of the root system, namely: T1 = 25 cm; T2 = 50 cm; T3 = 75 cm; T4 = 100 cm; and T5 = 125 cm. At 120 days after emergence (DAE), the seedlings were transplanted to the field and the following variables were evaluated: plant height (cm) and base diameter (mm) at 120 DAE; total titratable acidity (TTA), total soluble solids (TSS), Ratio (TSS/TTA); and fruit yield. The cultivation of tall seedlings with a long root system provides the maintenance of production during the dry season. The TTA, TSS, and the ratio do not change when modifying the length of the root system, although they do change with the harvest season. The cultivation of passion fruit in an organic system using plants with a long root system with an estimated length of 114 cm provides a higher fruit yield (7,472 kg ha-1) in 22 months of cultivation.

“…Although some studies highlight the technical and economic viability of organic passion fruit production in Acre (ALVES et al, 2018;ARAÚJO NETO et al, 2014;GALVÃO et al, 2020;REZENDE et al, 2017;SILVA et al, 2020;UCHÔA et al, 2021a), fruit production in that state is still insufficient to supply the local market (IBGE, 2020) due to the lack of studies and cultivation technologies.…”

Profitability of Organic Yellow Passion Fruit as a Function of Irrigation, Protected Cultivation and Pollination

Passion fruit production has become an attractive activity due to its social and economic benefits, given the rapid economic return and well-distributed income over most of the year. From this perspective, this study aimed to evaluate the technical and economic indicators of yellow passion fruit cultivation by combining irrigation, protected cultivation, and pollination. The experimental design was in randomized blocks set up in split plots (2 x 2 x 2), with eight treatments and four replicates containing four plants per experimental unit. The protected environment was installed on the upper part of each trellis and consisted of 100 m transparent plastic film as cover material. Irrigation was performed using a micro-sprinkler system, and pollination was either manual or natural (entomophilous). The following parameters were evaluated: commercial yield - estimated for one hectare considering the mass of marketable fruits produced in the plot (30 m2); production cost - capital depreciation, input prices, and labor used in cultivation; economic indicators - profitability index, family labor remuneration, profitability, net income, benefit/cost ratio, and fixed, variable, and total costs. The results show that artificial pollination increased the yield and provided a 41% higher profitability rate than natural pollination; supplemental irrigation, compared to rainfed cultivation, has no positive effects on profitability indices; protected cultivation increases the total cost and does not 0increase the yield; organic passion fruit production provides profitability indices ranging from 60% to 70%.

“…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.…”

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

This research aimed to evaluate the effect of doses of organic compost on the yield and economic profitability of organic yellow passion fruit grown in sandy-loam and clay-loam soils. Two experiments were installed in the field, in different soil types and municipalities in the state of Acre. The experimental design was in randomized blocks with five treatments, four replications, and four plants per experimental unit. The treatments consisted of adding the compost as a replacement for 1/3 of the volume of cylindrical planting holes with 40 cm, 80 cm, 120 cm, 160 cm, and 200 cm, corresponding to the addition of 6.3; 25.1; 56.5; 100.4, and 156.9 liters per planting hole, respectively. The mean fruit mass and the yield of the yellow passion fruit were higher in sandy-loam soil. The total revenue was R$ 4,311.6 ha-1 in the clayey soil and R$ 5,841.9 ha-1 in the sandy soil. The total cost was higher in the clayey soil than in sandy soil. Both soils responded in quadratic function with an increase in the cost as the volume of organic compost was increased, ranging from R$ 12,736.00 ha-1 with 6.3 liters of compost per hole up to R$ 26,249.63 ha-1 with 156.9 liters of compost per hole. Net income was negative for all compost volumes in both types of soil, responding linearly, with a reduction in revenue of R$ 80.82 ha-1 with the addition of each liter of compost in the pit due to the low yield caused by period long drought.
