“…A maximum plant height value at 136.5 cm was recorded by Giza 92 with N-Ca+K-H treatment, while a minimum value at 114.6 cm by Giza 94 with T-Ca treatment. These results are in agreement with Osman and Rady (2012); Seadh et al (2012) and Wei et al (2021) they found that the application of humic acid (HA) resulted in a significant increase in plant height. Calcium is highly involved in cell elongation and is required for the cell division process and cell wall strength (Heidaria et al, 2022).…”

“…Both foliar spraying on plants or as soil application of K-H can be used (Idrees et al, 2018). Compared to the control, K-H significantly increased cotton plant height and number of bolls per plant (Wei et al, 2021), improved wheat and rice growth and grains yield (Khan et al, 2018;Rabeh et al, 2021a), enhanced the chilli yield (Pavani et al, 2022), and improved seed, lint cotton yields and fiber quality (Rady et al, 2016). The soil K-H application and foliar application of humic acid improved plant height, fruiting branches number, number of open balls, boll weight, seed index, and seed cotton yield (Gebaly, 2012;Mohamed and El-Mgaed, 2020).…”

Calcium (Ca 2+ ) is one of the essential elements for plants and the changes in soil properties reduce its availability for plants as a result of forming insoluble compounds. The aim of this study was to evaluate the effect of foliar application of Nano-Ca (N-Ca) combined with potassium humate (K-H) on improving the cotton growth parameters, yield components and fiber quality. Two split-plot design field experiments (2019 and 2020) in a randomized complete block design arrangement with four replicates were laid out. Three cotton cultivars (Giza 92, 94 and 95) and six fertilizers treatments (control; traditional-CaO (T-Ca); Nano-CaO (N-Ca); K-H; T-Ca+K-H; and N-Ca+K-H) were applied. The foliar spray was performed four times (30 days after sowing, at squaring, beginning of flowering and 15 days later). Results indicated the superiority of Giza 95 was in the yield while Giza 92 and 94 cotton cultivars were in the quality of fiber. Individual foliar applications of N-Ca and K-H had a significant increase in plant height, yield components (sympodial branches, total and open bolls, boll weight, seed index, lint% and seed cotton yield) and fiber quality (fiber length, uniformity index, fiber strength, fiber fineness and reflectance (Rd %)) and decrease yellowness (+b) compared with the control. Foliar N-Ca was more efficient as fertilizer than T-Ca. N-Ca combined with K-H achieved a higher increase of most previous traits than T-Ca with K-H. Application of N-Ca combined with K-H could be recommended to improve cotton production and fiber quality.

“…Under SM conditions, higher FHY was obtained at HA 40 and HA 20, whereas without mulching, it was seen that the HA applications were not significant ( Table 5 ). Potassium humate significantly increased cotton stem diameter, boll number per plant, plant height, and leaf area index compared to the control under the film-mulched drip irrigation system [ 8 ].…”

“…To maintain a limited but appropriate level of drip irrigation, soil mulching is one of the sustainable agricultural methods to preserve the moisture of the soil and increase crop yield [ 4 , 5 , 6 ]. Soil mulching serves with efficient weed control, preserves water evaporation, produces cleaner crops, and protects them from diseases and pests [ 7 , 8 , 9 , 10 , 11 ]. In addition, it improves soil temperature, increases the soil’s organic carbon stock, and reduces greenhouse gas emissions [ 12 ].…”

The adoption of suitable irrigation levels (IRL), humic acid doses (HAD) and soil mulching (SM) are important tools for improving the morpho-physiological and biochemical traits of medicinal and aromatic plants. Ocimum basilicum L. cultivated under four IRL: IRL 100 = 100% FC–IRL 75 = 75% FC–IRL 50 = 50% FC–IRL 25 = 25% FC and four HAD: HA 0 = 0.0 Lha−1–HA 10 = 10.0 Lha−1–HA 20 = 20.0 L ha−1–HA 40 = 40.0 L ha−1 were applied in order to evaluate morpho-physiological and biochemical traits under the ecological conditions of Eskişehir in 2016 and 2017. A second trial was conducted with black plastic soil mulch (SM) and compared with the control plots (CP) in 2016. The experiment was arranged in a randomized complete block design with split plots and three replications. The plant height (PH), fresh herb yield (FHY), dry herb yield (DHY), dry leaf yield (DLY), protein ratio (PR), and main essential oil compounds (MEOC) of Ocimum basilicum L. increased and the essential oil ratio (EOR) and essential oil yield (EOY) decreased with increasing IRL (IRL 100 and IRL 75). FHY (7268.3 and 7472.7 kg ha−1) and DLY (635.3 and 637.5 kg ha−1) increased with increasing HAD (HA 20 and HA 40) compared to the values of FHY and DLY at HA 0 (6852.6 and 587.0 respectively). The SM application at IRL 50 increased the PH between 8.8 and 13.5%, FHY 11.7 and 16.7%, DLY 22.5 and 29.2%, and at IRL 75 the EOY between 20.0 and 23.9% compared to CP. In addition, PH, FHY, DLY, and EOY were highest at HA 40 and HA 20. The MEOC (linalool, 1,8-cineole, and (E) – β-bergamotene) under SM were more pronounced at IRL 25 and IRL 50 compared to CP. HA particularly improved FHY, DLY, and the main essential oil compounds that can be considered plant biostimulants, which were defined by several studies and regulations.

“…Various environmental factors, such as strong winds, extreme temperatures, soil salinity, droughts, and floods, affect the production and cultivation of agricultural crops. As one of the most destructive environmental pressures, soil salinity causes an obvious decrease in the area of arable land, crop productivity, and the quality of crops [ 1 , 2 ] and it is the main factor in the agricultural economy in arid areas [ 3 ]. High salinity affects about 20% of the arable land and 33% of irrigated farmland worldwide.…”

Brackish water has to be used to irrigate crops for harvest due to the scarcity of freshwater resources. However, brackish water irrigation may cause secondary soil salinization. Whether the combined utilization of different non-conventional water resources could relieve the risk of secondary soil salinization has not been reported. In order to explore the safe and rational utilization of brackish water in areas where freshwater resources are scarce, a pot experiment was conducted to study the risk of secondary soil mixed irrigation and rotational irrigation using brackish water and reclaimed water or freshwater. The results indicated that: (1) Short-term irrigation using reclaimed water did not cause secondary soil salinization, although increasing soil pH value, ESP, and SAR. The indices did not exceed the threshold of soil salinization. (2) Compared with mixed irrigation using brackish–freshwater, the contents of soil exchangeable Ca2+, K+, and Mg2+ increased, and the content of soil exchangeable Na+ decreased under rotational irrigation using brackish-reclaimed water. In addition, the contents of soil exchangeable Na+ and Mg2+ under mixed irrigation or rotational irrigation were significantly lower, and the exchangeable K+ content of the soil was higher compared with brackish water irrigation. The exchangeable Ca2+ content under rotational irrigation was higher than that of brackish water irrigation, while the reverse was seen under mixed irrigation. (3) For different combined utilization modes of brackish water and reclaimed water, the ESP and SAR were the lowest under rotational irrigation, followed by mixed irrigation and brackish water irrigation. The ESP under brackish water treatment exceeded 15%, indicating a certain risk of salinization, while ESPs under other treatments were below 15%. Under mixed irrigation or rational irrigation using reclaimed-brackish water, the higher the proportion or rotational times of reclaimed water, the lower the risk of secondary soil salinization. Therefore, short-term combined irrigation using brackish water and reclaimed water will not cause the risk of secondary soil salinization, but further experiments need to verify or cooperate with other agronomic measures in long-term utilization.
