Quality of Amazonian spinach seedlings (Alternanthera sessilis) produced with different substrates

Abstract

Amazon spinach is a vegetable classified as an unconventional food plant, easily found in the Amazon region, it has excellent nutritional properties, highlighting its high protein content. The objective of this work was to evaluate the quality of Amazon spinach is a vegetable classified as an unconventional food plant, easily found in the Amazon region, it has excellent nutritional properties, highlighting its high protein content. The objective of this work was to evaluate the quality of Amazonian spinach seedlings produced using different substrates. The experiment was carried out in a greenhouse in the experimental garden of the Federal University of Acre, from July to August 2022. The experimental design was randomized blocks, with three treatments and four replications. To evaluate the seedlings, eight plants were used per block. The treatments were 3 substrates, as follows: T1 = 100% commercial substrate, T2 = 100% crushed chestnut shell and T3 = 50% commercial substrate + 50% crushed chestnut shell. There was a significant effect of the substrates for the variables: leaf width, plant height, total number of leaves, total number of roots, root length, fresh and dry mass of shoots, roots and total and the Dickson quality index. The compound treatment with a mixture of 50% commercial substrate + 50% crushed chestnut shell provides quality seedlings.
