“…With regard to biopreparations, the stimulating effect on plant development may have been caused by chitosan polymers and humic acids contained in Apol-Humus as well as the nutrients, humic acids and iodine present in Stymjod. The positive effect of humic acids on plant development is well described in the literature (Calvo et al, 2014;Fahramand et al, 2014;Abdellatif et al, 2017). The beneficial effect of chitosan on the development and health of grape was revealed by Górnik et al (2008) and on the growth of some other horticultural crops by Pichyangkura and Chandchawan (2015), Bistgani et al, 2017), Mukta et al (2017), Muxika et al, (2017) and Kashyap et al (2015).…”

An increase in plant productivity and the limitation of environmental pollution through the use of natural fertilizers are becoming the most important issues in contemporary sustainable agriculture. Therefore, the purpose of the research was to demonstrate the effect of Jerusalem artichoke ash, used alone or together with biopreparations and biogas plant waste, on the growth and physiological activity of sorghum and to show their applicability as an alternative to chemical fertilization. The sorghum plants, cultivated in Central and North Poland, were fertilized with the YaraMila Complex, a chemical fertilizer (0, 150, 300 kg ha-1) and each concentration was supplemented with Jerusalem artichoke ash (0-4 t ha-1), applied separately or together with Apol-Humus (10 L ha-1), biogas plant waste (30 m 3 ha-1) and Stymjod (5 L ha-1). Within each YaraMila Complex addition, the all ash doses (preferably 2-4 t ha-1), biopreparations and biogas plant waste significantly enhanced plant growth, biomass yield, chlorophyll content, gas exchange (net photosynthesis, transpiration, stomatal conductance, intercellular CO 2 concentration), enzyme activity (acid and alkaline phosphorylase, RNase, dehydrogenase) and slightly enhanced the content of the measured elements in plants and their energy properties. The ash applied together with a lower than recommended amount of YaraMila Complex (0 or 150 kg ha-1) increased plant development slightly more than twice the dose of YaraMila Complex used alone (150 or 300 kg ha-1 , respectively). This demonstrates that the studied ash can serve as a natural fertilizer and may halve the recommended chemical fertilizer doses.

“…The application of Ascophyllum nodosum extracts as plant biostimulants has been reported in several studies [19,22]. Humic acid may increase the leaf area, stem diameter, plant dry weight in different plants [23,24] and may ameliorate stress conditions in tomatoes [25]. Potassium, phosphorus, and microelements play critical roles in the growth and morphology of most plants [26,27].…”

Effects of Water Stress and Modern Biostimulants on Growth and Quality Characteristics of Mint

et al. 2019

Natural biostimulants combine different elicitors that may influence economic properties of herbal crops, such as mint. Mint (Mentha longifolia L.) plants were subjected to three water levels based on container substrate capacity (CSC; 100% CSC, 70% CSC, and 50% CSC) and/or applications of four biostimulants (CRADLE™, Mobilizer™, Nanozim De’Lite™ [ND], and Nanozim NXT™ [NN]). ND and NN exhibited higher vegetative growth and root dry weight than the control (without biostimulants) and other treatments. NN produced the highest fresh and dry mint yields under all water levels. Irrigation water-use efficiency (IWUE) of NN was highest (2.78 kg m−3) with 70% CSC, whereas the control produced the lowest IWUE (1.85 kg m−3) with 100% CSC. Biostimulants boosted physiological and metabolic responses, including gas exchange, leaf water potential, relative water content, and proline accumulation of stressed plants. NN treatment with 70% CSC had the highest essential oil (EO) ratio (3.35%). Under 70% and 50% CSC with NN treatment, the proportion of 1,8-cineol increased and that of pulegone decreased in EOs. Increased antioxidant activities, reduced H2O2 levels, and increased catalase and superoxide dismutase activities were observed. Applications of ND and NN during water stress conditions increased economic and medicinal properties of mint EOs with applications in the agricultural and pharmaceutical industries.

“…Moustafa et al (2016) concluded that the use of PH as organic fertilizer is recommended to replace partially chemical fertilizer. Abdellatif and Abdel-Ati (2017) stated that humic acid application targeted agreat results on tomato plant growth and productivity as compared with control. Osman et al (2017) recommended that application of PH as a foliar spray for improving the quality and quantity of wheat cultivated in salty lands.…”

In order to investigate the influence of spraying with proline and potassium humate (PH) on productivity and chemical components of Broad bean, cv. Koprosay, two field experiment were conducted at a private Farm in Rowad Village belong to Sahl El-Husseiniya, Sharkia Governorate throughout 2016 and 2017 seasons. Randomized complete blocks design was used with three replications. Height of plant, No. of leaves/plant, total chlorophylls, leaves fresh and dry weight, length and wide of pod, green seeds number per pod, the weight of 100 green seeds, total yield, N, P, K and proline percentages in leaves N, P, K, total carbohydrates and crude protein percentages in green pods were estimated. Spraying broad bean plants with 2 L PH/fad in addition 100 mg proline/L produced the highest values of all estimated traits in both seasons. Accordingly, it could be suggested that spraying broad bean plants grown under saline soil with 2 L PH/fad and 100 mg proline/L to improve growth characters and yield in addition to chemical components of broad bean.
