Pityrocarpa moniliformis Benth. has medicinal properties, forage potential, besides showing rusticity and rapid growth, which confer potential to recover degraded areas. In this context, the objective was to evaluate the growth and biochemical components of Pityrocarpa moniliformis seedlings under water deficit conditions. The design used was randomized blocks, with five treatments and four replicates, with the experimental plot consisting of twenty plants. Treatments were characterized by different periods of water deficit (0; 4; 8; 12 and 16 days without irrigation). At 44 days after sowing (DAS), when the seedlings had two pairs of fully formed true leaves, the treatments began to be applied. The development of the seedlings was evaluated until 60 DAS when they were collected for biometric and biochemical analyses. The variables analyzed were shoot height; collar diameter; number of leaves; shoot dry mass; root dry mass; root/shoot ratio; and Dickson’s quality index. Contents of total chlorophyll, chlorophyll a, chlorophyll b, total free amino acids, total soluble sugar, and proline contents in the leaves were also determined. The treatment most affected by the lack of irrigation was 16 days of water deficit, which resulted in the death of 38.8% of the seedlings. This condition caused a decrease in shoot length, reducing it by approximately 29.2% compared to the control treatment. There was also a reduction in the production of new leaves from the eighth day after the differentiation of treatments. Pityrocarpa moniliformis seedlings can develop under the condition of water deficit for up to 8 days, even with chlorophyll degradation due to stress. Pityrocarpa moniliformis maintains its vegetative development by performing osmotic adjustment through the accumulation of biomolecules (sugars, proline, and amino acids).

“…Besides the limitations in the amount of the irrigation water, the irrigation qualities of the waters in the basin are crucial to be inspected to determine the applicability of the irrigation water for the intended plantings [4]. Because of the incorrect irrigation water usage, farmers face a lack of efficiency or plant decays besides time and economic losses, and targeted planting cannot be achieved [5][6][7]. To prevent these losses, classification of the irrigation waters for intended purpose becomes valuable [8].…”

Turkey is a country that has available climate conditions and water sources utilizable for agriculture. Most surface waters in the country can be applicable for irrigation purposes. Electrical conductivity (EC) is a measure of the salinity of the irrigation water, while salinity can also be directly measured in ppm. High salinity water prevents the water supply of the plant roots due to the high osmotic pressure, in other words reduces the availability of irrigation water. Sodium adsorption ratio (SAR) is an indicator of the quality of the irrigation water that is a measure of the sodium amount relative to calcium and magnesium amounts. High SAR values in the irrigation water result in impermeability in the soil meanly infiltration problems following a decrease in the water supply by the crop. In this study, four selected surface waters from the East Mediterranean Basin were chosen to evaluate their availability for the purpose of irrigation. Since the East Mediterranean Basin is a productive land due to its climatic conditions, monitoring the quality of the irrigation water of the basin becomes crucial. The selected surface water bodies were analyzed at three-month intervals between 2015 and 2019. The salinity and alkalinity classes were found to be C2-S1 which corresponds to good irrigation water quality and can be used to irrigate all types of plants.

Organic mulching has been suggested as an option for managing spontaneous species in restoration plantings and can promote improvements in soil properties and performance of planted species. The aim of this study was to test the effect of crowning techniques on soil microclimatic and performance of forest seedlings. The experiment was carried out in Goiás state, Brazil. Two study factors were used: crowning techniques (manual weeding, cardboard, wood chipping and control—without weed competition management), and six tree species: Anadenanthera peregrina, Ceiba speciosa, Dipteryx alata, Inga edulis, Genipa americana and Spondias mombin. Soil temperature and moisture assessments were performed within the crowning area (0.25 m2). Seedling survival and growth in height and diameter were evaluated over 219 days. Organic mulching treatments of wood chipping and cardboard provided increase in soil moisture and decrease in temperature, resulting in higher seedling survival rate. The increase in height and diameter differed among species under study, with A. peregrina standing out in height and C. speciosa in diameter. The crowning techniques did not influence the average height of species; however, wood chipping provided greater diameter increase. The findings of this study indicate that mulching treatments, by contributing to increase soil moisture and decrease soil temperature, can be used as crowning techniques to increase the survival rate and diameter growth of tree species in restoration plantings.
