“…The adaptability of the achachairu in substrates with high amounts of cattle manure are in accordance with the observations by Silva et al (2013) who report that substrates containing 50% of cattle manure associated with vermiculite or commercial substrate can be indicated for the formation of coffee plant seedlings, as well as Costa et al (2014) report that substrates containing 33, 50 and 100% of cattle manure can be indicated in the formation of bocaiúva seedlings (Acrocomia aculeata).

“…The amount of shading (luminosity) is an essential factor on the initial growth of achachairu and this requires at least 40% of shade (Daniel, 2009). Better Acrocomia Aculeata seedlings were observed in Aluminet ® , when compared to Sombrite ® and to the greenhouse with low density polyethylene (Costa et al, 2014). However, Costa et al (2012b) did not find differences between the Sombrite ® and Aluminet ® , both with better results than in the agricultural greenhouse for 'baruzeiro' seedlings (Dipteryx alata), diverging from Costa et al (2015) who reported better baruzeiro seedlings in Sombrite ® compared to Aluminet ® .…”

The Achachairu (Garcinia humilis) is a Bolivian exotic fruit that has been produced and commercialized a few years in Brazil. Information about the production of high quality seedlings is essential for the implementation and the renewal of orchards. The objective was to evaluate protected environments and substrates for Achachairu seedlings. Two protected environments were evaluated, one covered with aluminized thermal reflector screen of 50% of shading and the other with Sombrite® of 50% of shading. Inside the protected environments were tested substrates derived from combinations of various proportions of cattle manure (CM), ravine soil (RS), medium vermiculite (MV), super fine vermiculite (FV) and sand (S). For each protected environment was adopted a completely randomized design with 5 replications of 5 seedlings. Protected environments were compared by analysis of groups of experiments. All substrates studied formed high quality seedlings for the implementation of Garcinia orchards, with low rates of aerial and root phytomasses, low rates between height and stem diameter, providing higher Dickson quality index. The Aluminet® promoted the best seedlings with larger shoot, root and total dry mass.

“…According to DIAS et al (2009a) the use of manure on substrates, over 30% was not beneficial to coffee seedlings (Coffee arábica), however SILVA et al (2013) reported that substrates containing 50% of manure associated with vermiculite or commercial substrate may be suitable for the formation of coffee seedlings, as well as COSTA et al (2014) reported that substrates containing 33.33, 50.00 and 100.00% of manure may be indicated to the formation of "bocaiúva" seedlings (Acrocomia aculeata). *Uppercase letters in the same rows and lowercase in columns, for each parameter, do not differ from each other by the Scott-Knott test for the substrates and by the F test for cultivation environments, at 5% probability C = Cattle manure; S = ravine soil; M= medium vermiculite; F = super fine vermiculite; Sa = sand…”

ABSTRACT:The Brazilian copal is a tree fruit species that can be used for various purposes. The study evaluated protected environments and substrates in forming Brazilian copal seedlings (Hymenaea courbaril), at the State University of Mato Grosso do Sul, Cassilândia-MS, from January to March, 2014. Two greenhouses were used: (A1) agricultural greenhouse covered with aluminized thermal reflector screen of 50% shading and (A2) agricultural greenhouse covered with black screen of 50% shading. Inside the greenhouses, substrates derived from mixtures of cattle manure, soil, medium vermiculite, super fine vermiculite and washed fine sand were tested. For each cultivation environment, a completely randomized experimental design was used. The environments were compared by combined analysis. Emergence parameters, growth, phytomass and biometric relations were evaluated. The best seedlings were formed on the substrates containing 10 or 20% of cattle manure in the mix. Substrates containing 50% of cattle manure in the mixture did not favor the development of seedlings in the greenhouse with black screen. The best seedlings have been formed in the protected environment of aluminized screen coverage, with higher air and total phytomass, and Dickson quality index. Larger seedlings in height, with more leaves were formed in the protected environment with black screen coverage.

In the environment open air the plants showed the smallest height/collar diameter ratio (H / D).…”

ABSTRACT:The objective of this study was to evaluate the growth of rubber clones GT1, PR255, RRIM600 grown on different substrates and environments for the production of rubber rootstocks. The experiment was conducted at the Universidade Estadual de Mato Grosso do Sul, Cassilândia University Unit, in Cassilândia-MS. The treatments were conducted in 3 environments: (A1): Sombrite ® ; (A2) Aluminet ® and (A3) full sun, where the clones being tested were: GT1; PR 255 and RRIM 600, grown in substrates: pure soil; soil + cattle manure and commercial substrate usually used for forestry. The experimental design was a randomized block in a factorial 3 x 3 (three substrates x three clones), with 4 replicates with 10 seedlings of rubber trees per plot. The use of commercial substrate and soil + cattle manure in the ratio (7:1) favored the development of rubber rootstock seedlings with taller plants, more leave number, higher mass and higher quality index. For the formation of rootstocks, the variety RRIM600 was the one that showed better agronomic characteristics in the formation of rubber tree seedlings, with higher number of leaves, tallest plants, larger mass and higher quality index. The use of Sombrite ® and Aluminet ® screens contributed positively to the formation of rootstocks with larger root and above-ground masses. The plants produced in the Aluminet ® screen showed higher number of leaves.
