Tamarind Tree Seedlings in Protected Environments and Substrate

Abstract

This study aimed to evaluate the formation of tamarind tree seedlings in different protected environments and substrates. Five protected environments were used and substrates using combinations of different proportions of humus, cattle manure, vermiculite, and cassava stems. The environments with screens and the environments with polyethylene films were conducive to the emergence of the tamarind seedlings. All the substrates presented adequate conditions for the emergence of seedlings in these environments. The environment covered with bacuri straw was not favorable to the emergence of the tamarind seedlings. The substrates containing cattle manure provided the best conditions for emergence in the environment covered with bacuri straw. The greenhouses and the screenhouse with the aluminized screen and the substrates containing manure provided the largest number of leaves, larger plants, and larger diameters. The mixture of cassava stems and cattle manure, as well as the mixture of three or four tested materials, are conducive to the development and accumulation of biomass in tamarind seedlings. The mixture of humus with vermiculite or cassava stems is not indicated for the biomass accumulation in tamarind seedlings. Greenhouses and screens are indicated for the formation of high-quality seedlings.

Organic material as supplementation for substrate in papaya seedlings production

“…Similar effects were obtained for the development of different fruit species of economic interest, such as tamarind (SILVA et al, 2020) and, mainly, of vegetable species such as lettuce (WATTHIER et al, 2019), cucumber (SALLES et al, 2019;. The authors also relate the effects to the chemical composition and physical characteristics of the compound, which are beneficial to root and shoot development.…”

Colored Growing Benches with Different Wavelengths Increase Production and Bioactive Compounds in Baby Leaf Kale

“…Light is one of these environmental factors that play an essential role in the development and biosynthesis of health-promoting compounds. The ideal light environment helps to increase photosynthesis, photomorphogenesis, and the growth of horticultural crops [7,8]. Plants can perceive 2 light and respond to these stimuli through photoreceptors such as phytochromes and cryptochromes, generating various physiological responses [9].…”

“…Growing benches with reflective materials aim to reflect part of the photosynthetically active radiation that reaches the benches onto the leaves, providing a greater amount of light energy and improving the use of this energy to conduct photosynthesis. Studies were carried out showing the effect of reflective benches on different species such as Humulus lupulus [8], Solanum lycopersicum var. cerasiforme [13] and Dipteryx alata [14] with promising results.…”
