Effect of planting distances and Humic Acid application on some vegetative growth and yield of Broad bean (Vicia faba L. var. Somar) in outdoor condition

The seeds of the Somar variety (local production) were planted in mid of October (after being soaked with water for 16 hours) in panels 1.5 x 2 meters. Broad bean (Vicia faba var. Somar) was studied in outdoor to determine the effect of three planting distances (20, 25 and 30 cm), four different Humic Acid (HA) concentration doses (zero, 1.5, 3.0 and 4.5) ml / liter H2O, with three replicates on some of the plant’s vegetative and yield traits; Plant Height (cm), Plant Diffusion (cm), Number of Branches /Plant, Number of Flowers / Plant, Number of Pods / Plant, % percentage of Pods Set, Total Pods Yield /plant (gm), Pod Weight (gm). The (HA) were added by spray way directly to the top of the soil with two applications, the first after 3 weeks from complete germination, while the second after branching immediately. The experiment was designed as Randomized Complete Block Design (RCBD). Based on Total pods yield / plant (gm), the best interaction between the plant distance and different concentration of (HA) was a combination of the planting distance 30 cm, and treated the soil with 3.0 ml/ literH2O

Comparison of Growth Traits and Yields Components of five Chickpeas Genotypes (Cicer arietinum L.) at Bakrajo/ Sulaymaniyah Conditions

This study was carried out in Bakrajo Technical Institute, affiliates to the Sulaimania Polytechnic University. The investigation was done to find the relationships between genotypes and sowing times of five chickpeas (Cicer arietinum L.) during 2017-2018 seasons. Genotypes and sowing time are two significant variables which have impact on crop performance. However, heat stress throughout reproductive growth it is possible to cause Significant productivity loss. According to the environment conditions in winter season in the northern Iraq; crop meets slight heat and the acceptable moisture during reproductive growth and maturity. This leads to resulting in maximum and consistent yields, as well as there is a positive correlation between Maturity and Seed Yield (kg/h) as resulted from the experiment. Experimentation was laid out in a randomized complete blocks design (RCBD) with three replications applied. Results of analysis of variance outlined that there was significant difference between chickpeas varieties in the most of traits such as no. of branches per plant, 50 % flowering, no. of pods per plant ,leaf area , seeds weight per plant and the 100 seeds weight plus harvest index, which in turn give a share in to raise yields and yield components. Sowing time and varieties had significant effects on all measured trait, Ghab 1; Filip 2 and Filip 3 winters sowing genotypes gave higher seed yield, 1582.66, 1554.66 and 1533.33 Kg/h respectively. Minimum yield 662, 480 Kg/h was recorded in the Local and Swrka spring sowing genotype

Morphological Growth of Soybean (Glycine max L.) Treated with Soil Application of Humic Acid under Different Cultivation Periods

The demand of organic cultivation of plants is increasing and soil application of organic fertilizer reduces the hazardous usage of inorganic fertilizer and Humic acid is an organic compound derived from plant and animal residues and microbial cells with long-term physical, chemical, and biological processes. In addition, ultivation of soybean in Kurdistan region is not in a wide value therefore, the objective of this study was to determine the impact of soil application of different rates of Humic acid as an organic fertilizer on the growth characteristic of soybean cultivated and determining the best cultivation period for soybean growth. The experiment was conducted in randomized complete block design with two factor treatments and 3 replication, the first factor was one dose soil application of four different  Humic Acid rates (HAR) which were (0 (control), 2,4,6,8 g/L) and two cultivation period (CP) which were cultivation Period 1 (CP1) on 15 May 2022 and cultivation Period 2 (CP2) on 1st of  June 2022. Observations were made against the growth parameters of plant height number of branches, leaf area, root length, shoot fresh weight and shoot dry weight. The  effect of soil application of humic acid rates (HAR) was highly  significant on the plant height and root length and significant on the No. of branches, shoot fresh and dry weight. While, cultivation period insignificantly affected the growth parameter except for leaf area.  was significant. The maximum plant height, number of branches, leaf area, root length, shoot fresh and dry weight were observed with soil application of 8 g/L of humic acid  which were (82.83 (cm), 23.33, 8815 (mm2), 68.83 (cm), 503.33 (g) and 190.00 (g) respectively. The highest plant height (72 cm), number of branches (18.87), leaf area (7714 mm2), root length (57.13 g), shoot fresh (263.67 g) and dry weight  (102.93 g) were observed when the planted cultivated in 1st   period (CP1) compared to CP2
