“…The increase in cotton growth, yield and fiber quality in the treatments where the seed dressing of potassium humate was applied as compared to where no seed dressing at present may be due to the increase in the germination percentage and protection from the seed borne diseases. In the study of Hassanpana and Khodadadi [37], 70% germination of potato seed was found with potassium humate seed treatment while the germination with water and control treatment was 31 and 15%, respectively. In another study conducted by Bostan et al [38], we found higher germination (53.33%) for the 0.02 mL/seed treatment as compared to the seeds without seed dressing treatment.…”

“…The soil potassium humate application performed better where the seed dressing of 200 mL kg −1 was applied in the current study. This may be due to the better germination and protection from seed born disease due to the seed dressing of potassium humate and the better nutrient availability and uptake of nutrients through soil potassium humate application [37]. Therefore, the combined seed dressing and soil application of potassium humate provided better soil environments for higher cotton productivity as compared to the individual application of soil or seed dressing of potassium humate [45].…”

Humus is the stable form of added crop and animal residues. The organic matter after a long-term decomposition process converts into humic substances. The naturally occurring humus is present in less amount in soils of the arid and semi-arid regions. The addition of commercially available humic acid can, therefore, contribute to improving soil health and crop yields. The present study was conducted to evaluate the effect of potassium humate, applied through soil seed dressing, on cotton productivity and fiber quality attributes. Seed dressing with potassium humate was done at the rate of 0, 100, 150 and 200 mL kg−1 seed while in soil potassium humate was applied at the rate of 0, 10, 20 and 30 L ha−1. Results showed that the combined application of potassium humate by seed dressing and through soil application improved the soil properties, productivity and fiber quality traits of cotton. All levels of soil applied potassium humate (10, 20 and 30 L ha−1) performed better over seed dressing in terms of cotton productivity and fiber quality attributes. Among the soil application rates, 20 L ha−1 potassium humate proved better as compared to other rates (0, 10 and 30 L ha−1). Higher soil application of potassium humate (30 L ha−1) showed depressing effects on all the traits studied like the reduction of 12.4% and 6.6% in Ginning out turn and fiber length, respectively, at a seeding dressing of 200 mL kg−1. In conclusion, potassium humate seed dressing and soil application at the rate of 200 mL kg−1 and 20 L ha−1, respectively, is a better approach to improve cotton productivity. Soil potassium humate should not exceed a rate of 20 L ha−1 when the seed dressing of potassium is also practiced.

“…Often, dormancy breaking prior to planting is practiced to enhance sprouting, especially to obtain rapid and uniform sprouting. It appears that the use of growth regulator is potentially one of the most suitable methods to enhance germination in many crops [ 5 , 6 ].…”

“…Auxin plays an important role in initiating buds in many plants, a role similar to gibberellic acid. However, in recent years, humic acid which mimics the function of auxin [ 11 ] has become relatively popular and many reports on the advantageous of humic acid are available [ 6 , 12 ]. It is used as a substitute to auxin in order to minimize the cost of production.…”

Tubers of safed musli (Chlorophytum borivilianum) were immersed in three different concentrations of gibberellic acid (GA3) or humic acid (HA) prior to planting. The highest concentration of GA3 (20 mg L−1) and all concentrations of HA (5, 10, and 15%) appeared to hasten tuber sprouting and promote uniform sprouting pattern. The use of 20 mg L−1 GA3 or 15% HA successfully improved sprouting and mean sprouting time. Safed musli growth and development was improved through the increase in the number of leaves, total leaf area, leaf area index, and total fibrous root length. This directly influenced the number of new tubers formed. The use of 20 mg L−1 GA3 or 15% HA gave similar response with nonsignificant difference among them. However, due to the cost of production, the result from this study suggests that 15% HA should be used to obtain improved sprouting percentage, homogeneous stand establishment, efficient plant growth and development, and increased yield of safed musli.

“…Potato tubers remain dormant for up to 10 weeks depending on the variety and seasonal weather conditions during the growth period [6]. Seed treatment by potassium humate for 6-12 h and seed direct planting in greenhouse percent without seed germination under in vitro, caused to increase seed germination percent [7].…”

A greenhouse experiment were conducted to study encouragement germination capacity of some potato tuber cultivars. The mean aim of this experiment was to assess the effect of some plant growth regulators treatments i.e. IAA and GA3, soaking time i.e. at (10 minutes, 20 minutes and 30 minutes on some germination and vegetative parameters of some potato cultivars i.e. Cara, Draga and Spunta. The results showed that Cara cultivar recorded highest germination index followed by Cv. Spunta without significant differences between them. Draga cultivar recorded tallest plant, highest fresh weight and dry weight in gm/plant followed by Cv. Cara for plant height only and followed by Cv. Spunta for fresh and dry weight without significant differences between them. Highest germination index percentage, tallest plants and highest fresh and plant dry weight were obtained from soaking tubers in GA3 at 10 ppm plus IAA at 6 ppm. While, soaking tubers in GA3 at concentration of 10 ppm produced highest mean of germination time. Results clearly indicated that soaking tubers for 30 minutes produced highest fresh weight followed by soaking for 20 minutes without significant differences between them. The interaction among cultivars and growth regulator treatments recorded significant differences on mean germination time, fresh weight and dry weight. Within this context, it is important to recognize the role of some growth regulators, soaking times and their interactions on encouragement germination capacity of some potato tuber cultivars.
