“…The obtained results in the application experiment were in agreement with the results obtained by Suresh et al, [34] who treated crop plants (zea mays,sorghum bicolour) with heterocystous cyanobacterial filtrate (0.2-0.5%) which promoted grain seedling growth. Also, using similar bio-stimulants [35,41] reported an amplification of seed germination percentage and root, shoot lengthening of the germinated plants.…”

“…Plant growth regulators are universally used for enhancing growth and development of many economic crops and vegetables [9,11,31,32,34]. They are naturally occurring organic compounds which influence the physiological processes that control cell division, embryogenesis, as well as the sequential growth and differentiation processes that are involved in the course of plant reproduction [31,35,36].…”

“…These biostimulants may induced an enhancement effect to plant growth [10] by facilitating water uptake, root and shoot growth and tolerance to stresses on all plant developmental stages (as germination of seeds, growth of plants seedlings till plant harvest). Lower concentrations were found to be more effective either applied for seed germination or seedling growth [11,12].…”

The aim of this work is to develop an efficient method for detection and evaluation of the plant growth regulators produced from cyanobacteria species (Anabaena oryzae and Nostoc muscorum) cultivated on BG110, and Chlorophyta alga (Chlorella vulgaris) cultivated on BG11 in addition to the cultivation of these strains on treated sewage wastewater (TSW) combined with control media (BG11 and BG110) at different concentrations (100, 75 and 50%). Bioassays were performed on Wheat coleoptile length and Cucumber cotyledons fresh weight for indole acetic acid (IAA) and Benzyl adenine (BA) detection. In addition, application experiments of IAA and BA presence in algal extract were applied on tomato plantlets and soybean callus. The obtained results of A. oryzae and N. muscorum extracts (grown on BG110 and 100% sewage media) with optimum conc. of IAA and BA showed moderate shoot length and leaves number as well as high root initiation of tomato explant compared to control. While dimethyl sulfoxide (DMSO), IAA conc. as well as IAA + BA conc. showed no effect on branching and leaf expansion. The results of C. vulgaris (grown on BG11) also revealed that the shoot had high leaves number and greatest root initiation, without branching and leaf expansion. On the other hand, 100% TSW had a moderate shoot, leaves number and high root initiation. Extracts of A. oryzae and N. muscorum (grown on BG110) induced 1.5-fold increase in soybean callus fresh weight, while the growth on 100% TSW was shown to be less effective. Moreover, extract of C. vulgaris (grown on BG11) induced a moderate effect, while its growth on 100% TSW was shown to be less effective in soybean callus fresh weight increment.

“…Kinetin was also observed in the cyanobacteria plus PGPRs cultures especially for Calothrix sp. co-cultivations (Table 4), this fact suggesting that phytohormones can selectively be released either by the plant or by the cyanobacteria (Ali et al, 2009a;Manjunath et al, 2011;Suresha et al, 2019). Nonetheless, release of cytokinins and auxins is known to be dependent on the plant growth cycle (Singh, 2014), a fact that may lead to varying results between studies and measurement methods.…”

“…The growth and development of the plant is a process in life and propagation which depends on the results of assimilation, hormones and substances of environmental growth that support and produce a pattern of growth (Gardner et al, 1991;Saleem et al, 2019;Mok, 2019;Gamez et al, 2019;Suresh et al, 2019). The availability of nitrogen is very important for plant growth because these compounds are the main proetin constituents and the main and irreplaceable amino acid molecules.…”

This study aims to determine the growth patterns of four types of local garlic (Allium sativum L.) and to obtain the adaptive appearance of the agronomical characteristics with maximum tuber weight in two different altitude places. The research was conducted in the Borah garlic farmer garden, Wiyurejo village, Pujon subdistrict, Batu city with an altitude of 1200 m above sea level, daily temperature of 15-20C and average rainfall of 21.400 millimeter/year and in the UB pilot garden of Cangar, Tulungrejo Urban village, Bumiaji Sub district, tourism city of Batu with an altitude of 1600 m above sea level, daily temperature of 17.5-22.8C and average rainfall of 2733 millimeter/year/year. The experimental design used was a Nested completely randomized design. The parameters observed were measuring plant variables consisting of plant height, number of leaves, leaf area, tuber diameter, tuber wet weight, tuber dry weight and tuber dry weight (tons per hectare). The results showed that the best growth pattern occurred at an altitude of 1600 m above sea level with 10 weeks after planting/meters sea level (weeks after planting). On the other hand, the highest weight is found in the type of Atsabe (3.932ton ha 1) but not significantly different from Saigon (3.735ton ha 1) at altitude of 1600 m above sea level as well as genotype of Saigon (3.628ton ha 1) and Atsabe (3.355ton ha 1) at altitude of 1200 m above sea level. Besides that, the highest percentage of allicine is found in the varieties of Atsabe (19.18%) and the lowest is found in the varieties of Sembalun (4.87%) at an altitude of 1200 m above sea level. For the growth and productions of local garlic plants from the four varieties, it is recommended to use Saigon and Atsabe genotypes at altitudes of 1600 m above sea level and 1200 m above sea level.
