“…The use of organic products has received a lot of attention in the recent period, furthermore, this new system of agricultural production that contain Humic acid has become one of the most important organic compounds used in this field, if it is found that the addition of humic acid to soil leads to increase the cation exchange capacity of soil and increases its pH and thus increases the availability of nutrients and increases the growth of roots and their branches (7) . (8) found in their study on Anna cultivar apples that the addition of humic acid to soil by 30 cm 3 .tree -1 has led to significant increase in the number of leaves per branch -1 and the area of the leaf increased with an increase in yield by 25.6% in addition to an increase in the average weight of the fruit and the percentage of total soluble solids, (9) also obtained similar results when studying Annacultivar apple trees, and (10) stated an increase in tree yield, fruit count per tree, and average of fruit weight of pear (Leconte cultivar) when adding 100 ml per tree of humate-NPK combination (10% humate ratio) to the soil. (11) Had gained the same results on apricot trees (Canino cultivar).…”

The research team had conducted this work at a private orchard in Saqlawiya -Falluja district in 2019 to investigate the influence of foliar application of liquorice (glycyrrhizin) extract (GLE) and humic acid (HA) on some vegetative growth traits and yield of Al-Ibrahimi apple cultivar. The factorial experiment consisted of 2 factors; the first one was GLE which consisted of 3 levels (L0, L1, L2) of (0, 3, and 6 g.L -1 ) respectively; while the second one was HA with 4 levels (0, 2, 4, and 6 g.L -1 ) had symbols of (H0, H1, H2, and H3) successively. Thus, the total number of treatments was 12 of 3 replications. Every apple tree considered as an experimental unit. The HA treatments were applied 7 times to soil every 20 days starting from 20 th February 2019 while the foliar applications of GLE were 5 times starting from the 1 st April in the same year.A significant improvement in vegetative growth, quantity, and quality of yield due to GLE and HA applications has been shown in increasing individual leaf area (LA), length of branches (LOB), number of leaves (NOL), total chlorophyll content in leaves (TCL) , and total carbohydrates content in leaves (TCCL), average weight of fruits (AWF), and number of fruits per tree (NFT) that reflected positively on increasing yield per individual tree (YPT), total percentage of soluble solids (PSS), vitamin C content in fruits (CC) , and decreasing acidity of fruits (TPA). The interaction between factors had significant influence in most of studied traits. Thus the L1H3, L2H2, and L2H3 treatment had the best results.

“…Attributable to its positive influence on the soil, compost amendment significantly alleviated the harmful effects of drought resulting in better growth and yield. Bio stimulants like EM, have a positive roles in sustaining the ecosystem (Farrag and Bakr, 2023), such as: Lactobacillus Rhodopseudomonas, and Saccharomyces (Shalan, 2014). They improved growth, yield and maturing of lettuce crop (Rashwan & El-Saied, 2022).…”

for two following seasons of 2021/ 2022 and 2022/ 2023, to examine effective of fertilization (100% NPK or control, 80 % NPK & EM (Effective microorganisms) applied at (12.35L ha -1 ), 80 % NPK & compost 12.35 ton ha -1 and 80 % NPK & Mixture of EM and compost) on wheat that grown in clay soil via using three cultivation methods, i.e. broad casting, ridges, raised beds. The experiment was arranged in a split plot design by three replicates. Water productivity as well as water use efficiency were extremely improved under raised bed method compared with the values with the other two methods through two seasons. Likewise, the highest values of plant height (cm). grain yield (ton ha -1 ), straw (ton ha -1 ), 1000 grain and protein% in the two consecutive seasons, were gained when planting wheat on raised bed at combined 80% NPK+ mix (EM and compost). Nutrition contents in wheat grain and total uptake kg ha 1 were increased with the same treatment.

A two-year (2020-21) study was conducted to investigate the possibility of relying of ten-years old pear trees grown on sandy loam soil irrigated by drip on citric acid (CA), gibberellic acid (GA3) and humic acid (HA). The CA was applied at the concentrations of 500, 1000 and 1500 ppm, GA3 at 50, 100 and 150 ppm and HA at 3, 4 and 5%, whereas water spray was used as the control. The results of our study proved that CA, GA3 and HA improved the shoot length, shoot thickness, leaf area and leaf chlorophyll of pear as compared with the control. Moreover, they also positively increased the fruit set percentage and final yield of ‘Le Conte’ pear. The fruit weight, size and firmness were also improved under the influence of aforementioned treatments. The fruit soluble solids, total sugars, leaf nitrogen, leaf phosphorus and leaf potassium of pear were also enhanced as compared with the control. Additionally, spraying of GA3 at 150 ppm, as well as, HA at 5 and 4% were the superior treatments and showed the most significant impact on plant growth, yield, fruit quality and leaf mineral content of pear. This study provides a basis for the future elucidation of HA-, GA3- and CA-modulated molecular mechanisms in pear, which can make a significant contribution in the scientific community.
