Chemical Soil Attributes, Accumulation of Foliar Macronutrients and Productivity of the 'Vitória' Pineapple Plant Fertilized with Urea and Chicken Manure

Abstract

The pineapple plant cultivar 'Vitória' is resistant to Fusarium and it presents similar characteristics to the cultivars 'Pérola' and 'Smoot Cayene'. However, the expansion of this new cultivar depends on the development of research on several aspects, among them, fertilization. In this context, the experiment was carried out with the objective of evaluating soil fertility, foliar macronutrient contents and productivity in 'Vitória' pineapple plant in function of nitrogen fertilization with urea and chicken manure. The experiment was conducted under randomized block design, with four replications. Treatments consisted of five doses of N, in two sources of organic fertilization (chicken manure ) and mineral (urea), totaling nine combinations generated through the Central Composite Matrix of Box: T1 , 44 and 2.91; T 2 , 152 and 0; T 3 , 0 and 10; T 4, 44 and 17.1; T 5 , 260 and 2.91; T6 , 152 and 10; T7 , 152 and 20; T8 , 304 and 10; and T9, 260 and 17.1 g plant-1. At 6 months after planting the chicken manure decreased H + A1, Mg and CEC levels, and at 23 months after planting increased soil P, SB e CEC levels. In the two seasons, Urea has reduced pH and it reduced Mg, SB and CEC contents at six months after planting. Doses of urea between 10 and 12 g plant-1 are recommended in order to maximize the productivity of the pineapple plant.

Organic Fertilization in 'Pérola' Pineapple Increases Fruit Production and Physical and Chemical Characteristics

“…(Santos et al 2014) who studied the nutrition of pineapple crown sprouts, (Silva et al 2014), who studied the decomposition and release of nutrients from organic sources, and (Irineu et al 2018) studied the application of organic fertilizer in melons. Studies have shown the benefits of using organic fertilizers for crop growing, such as poultry litter in pineapple (Pereira et al 2019), humic acids in pineapple crown sprouts (Santos et al 2014), and biofertilizer based on bovine manure in melons (Irineu et al 2018). The decomposition and nutrient release from poultry little and cattle manure have also been studied (Silva et al 2014).…”

Can fertilization with sewage sludge contaminate pineapple fruits with phthalates?

“…Pineapple is a fruit plant with high nutritional demand, mainly for nitrogen (Leonardo et al 2019). Thus, sewage sludge and its derivatives can be used as nutrients source for this crop and as alternative in order to reduce its production costs (Mota et al 2018).…”
