“…When plants are under extreme water stress, they often reduce their leaf area, stop producing new leaves, or drop their older leaves to conserve water [3] . Results of the present study are in line with the findings of Gonzales et al [30] , Oboho and Igharo [26] , Olubode et al [29] , Ogunrotimi and Kayode [28] , Adelani [31] who reported that regular watering enhanced leaf area and photosynthesis in plants.…”

“…The significant number of leaves recorded in VWO followed by AWO could also be an indication that O. gratissimum requires enough water for proper growth and development and could be attributed to available nitrogen in the soil which was aided by its dissolution potential in soil watered daily and this facilitates its uptake. This agrees with the findings of Olubode et al [29] who found that as applied moisture content increased, plant nutrient uptake did as well.…”

Ocimum gratissimum is an essential plant because of its wide food and medicinal usage. Despite its relevance, its morpho-physiological compositions are influenced by several abiotic stresses. Hence, this study examined the effects of water stress on the growth and chlorophyll contents of O. gratissimum. Seedlings of O. gratissimum were grown in twenty-four pots, two per pot and were arranged using a complete randomized design with four groups: Very Wet O. gratissimum (VWO), Moderately Water Stress O. gratissimum (MWSO), Strongly Water Stress O. gratissimum (SWSO) and Adequately Watered O. gratissimum (AWO) as control. Fifty centiliters of water was applied in AWO once daily, VWO twice daily, MSWO once in three days and SWSO once a week. Growth parameters: Stem height, number of leaves, leaf area, stem girth and petiole length were determined one week after treatment for six weeks. Chlorophyll contents were determined at two weeks intervals after treatment for eight weeks. Descriptive statistics such as mean±standard deviation and one-way Analysis of Variance (p < 0.05) were done using SAS software. Results obtained showed the highest mean stem height (27.50 ± 0.29 cm), number of leaves (37.00 ± 9.0), leaf area (735.7 ± 4.12 cm2), stem girth (0.40 ± 0.00 cm) and petiole length (7.20 ± 0.40 cm) in VWO. Similar results were obtained for chlorophyll (56.70 ± 0.65 mg–1). It could be concluded that regular watering of O. gratissimum could promote growth and increase chlorophyll contents of the plant.

“…Water is a major constituent of all living organisms which is involved in important biochemical processes including photosynthesis thus its availability in adequate quantity and at biologically tolerable interval affects productivity of plant species (Emmanuel, 2014). The regular watering allows nutrient to dissolve and transport to appropriate area for leaf expansion for photosynthesis, hence the higher biomass under the well-watered condition (Olubode et al, 2016). Hartmann et al (2005) reported that water stress due to drought is the most significant abiotic factor limiting plant growth and development.…”

To obtain high quality and quantity forest seedlings, silvicultural practices have been implemented in the nursery. Watering and mulching are two the most important silvicultural treatments that must be managed carefully in forest nursery in order to obtain healthy seedlings. The aim of the present study was to evaluate the effect of irrigation periods, mulching treatments and their interactions on the growth and development of Paulownia tomentosa seedlings. A factorial completely randomized design (CRD) with two factors was applied. The first factor was four irrigation periods which were once daily (D1), once every two days (D2), once every three days (D3), and once every four days (D4). The second factor was two mulching treatments which were mulching (M1) and non-mulching (M2). Each treatment was replicated five times. Morphological and physiological parameters of identified seedlings were studied. It is found that the irrigation periods significantly effect on the studied parameters, where the highest value of stem height increment (45.5 cm), stem diameter increment (4.74 cm), leaf number increment (10.3), stem dry weight (28.78 g), leaf dry weight (18.21 g), root dry weight (63.04 g), total dry weight (110.01 g), stem mass ratio (0.27), Dickson quality i ndex (1.84), leaf area (3656.78 cm 2 ) and specific leaf area (200.18 cm 2 g -1 ) were recorded from the seedlings that watered daily(D1), while the lowest value of these parameters were obtained from the seedlings that watered once every four days(D4). Moreover, most of the biomass and physiological parameters were significantly affected by mulching treatments and the maximum value of them were found in the seedlings that mulched with hay. Thus, the study suggested that to enhance growth and development of Paulownia seedlings, the seedlings should be watered daily and mulched with an organic material.
