“…This fact results from well-developed roots, which promotes greater absorption of water and nutrients, boosts plant growth and produces good quality seedlings. Adequate nutrition promotes the growth of the aerial part and promotes better development of the roots, thereby benefiting the exploration of larger volumes of substrate and stimulating greater absorption of water and essential elements (Natale et al, 2018). The higher concentration of macronutrients in the carnaubeira palm butt and in the coconut shell provided the superior growth of the plants, which became a greater production of total dry matter.…”

The use of organic waste for the production of plant substrates is an important environmental and economic alternative. In this perspective, we performed a work in a greenhouse, with the aim of evaluating the effect of substrates from organic waste during growth, gas exchange and accumulation of mineral elements in 'Sunrise Solo' papaya tree seedlings. The experimental design adopted was completely randomized, with four treatments and five repetitions, with six plants in each repetition. The treatments consisted of four types of substrates, three from the composting of sewage sludge, green coconut shell and carnaubeira palm butt, and one was the Turfa Fértil® commercial. We evaluated biometric and physiological variables and accumulation of nutrients and heavy metals in papaya seedlings. The green coconut shell and carnaubeira palm butt substrates promoted superior results for growth, dry biomass, gas exchange and accumulation of nutrients, whereas the commercial substrate and sewage sludge produced seedlings of inferior quality considering all the analyzed variables.

“…These effects were more expressive in smaller plants when associated with the hydrogel use, probably because they are more susceptible to the stomatal deregulation caused by water deficit (Gonçalves et al, 2009) and adverse conditions of absorption, transport and ion distribution in plant parts (Natale et al, 2018).…”

During the process of adapting camu-camu on dry land, the fertilization management in local water conditions must be considered with tests of technologies available for cultivation. To that end, the objective was evaluating the effects of the fertilization with slow-release fertilizer (SRF) and hydrogel on the initial growth of camu-camu plants under different water conditions, in two consecutive experiments. In the first one, we evaluated the leaf mortality in two plant sizes (from 15 to 25 cm and from 35 to 45 cm), two hydrogel levels (presence and absence) and different hole fertilizations [A1-conventional fertilization-FC-(313 g of super simple + 37 g of urea + 41 g of KCl), A2 (357 g of SRF + 35 g of KCl), A3 (268 g SRF + 26 g of KCl), A4 (179 g SRF + 18 g of KCl) and A5 (89 g of SRF + 9 g of KCl)], under water deficit conditions. In the second experiment, the initial growth of larger plants was evaluated by using the same treatments for two years with water availability. Under water deficit, fertilizers A2 and A3, associated with hydrogel, were very damaging to the leaf growth, especially in plants with height values lesser than 25 cm. With water availability, using FC and A2 associated with hydrogel, and A4 and A5 in the hydrogel absence, favored the plant growth and the supply of chlorophyll 'b'. Applying SRF in adequate amounts is effective on the initial growth of camu-camu plants in the Savannah soil from Roraima.

“…The increase in cation exchange capacity, fertility and soil microbia can potentiate the production of quality papaya seedlings. The use of vigorous quality seedlings leads to rapid early papaya development and greater tolerance to pest and disease attack, increasing the benefit-cost ratio (Natale et al, 2018).…”

Papaya is a tropical fruit of great importance in the international and national market. For crop success, the use of quality seedlings is of paramount importance and substrates formulated from organic sources may be a viable alternative. In this context, the objective of this study was to evaluate the initial development of papaya seedlings in different formulations and levels of organic substrates. A completely randomized design was used in a 4x4+1 factorial scheme, corresponding to four substrate formulations, containing decomposed buriti stem (CDB). The treatments included of the following: (CDB, ½ CDB + ½ poultry manure, ½ CDB + ½ cattle manure and ½ CDB + ½ gray with plant origin sourced from materials resulting from the burning of plant material (stem, branches); four proportion levels of the formulations of the substrates mixed to the soil (25; 50; 75 and 100%) and the additional control (100% soil). The following variables were measured: plant height, leaf area, number of leaves, shoot dry matter, root length and root dry matter at 42 days of seedling cultivation. The results showed that use of an ideal source of organic matter is feasible in the production of papaya seedlings. The substrate consisting of CBD + poultry manure had great potential to be used in the production of papaya seedlings.
