EFFECT OF HUMIC ACID CONCENTRATION AND SPRAYING STAGES ON SEEDS YIELD AND ITS CONPONENTS OF ALFALFA

A field experiment was conducted at the experimental fields in the collage of Agricultural Engineering Sciences, University of Baghdad, Iraq during the period from mid. March 2019 to to end of July 2020. The main objective was to find out the effect of humic acid (HA) concentration (0, 1, 2 and 3 cm3.L-1) and three stages of foliar application (vegetative, growth, flowers buds emergence and 50% flowering) on seeds yield and its components of alfalfa local variety. Layout of the experiment was R.C.B.D arranged in split-plot, with three replications. Foliar application stages were used as main-plots, while humic acid concentrations were used as sub-plots. Results showed that spraying of HA at conc. 3 cm3.L-1 resulted in a significant increment in number of florets per raceme and number of pods per raceme, in contrast, % of florets abortion in and 1000 seeds weight were not significantly influenced by HA conc. and spraying stages. Highest number of the stems.m-2, number of racemes per stem, seed set and seeds yield (441.0) Kg.ha-1 were obtained from plants sprayed with HA at conc. 3 cm3.L-1. Plants sprayed at vegetative growth produce highest number of stems.m-2 number of raceme per stem, number of seeds per pod and seeds yield (423.6) Kg.ha-1. There was high positive correlation between seeds yield and each of, number of stems.m-2, number of pods per raceme and number of raceme per stem (+0.88**, +0.70** and +0.82**) respectively. There was a significant interaction between HA concentration and spraying stages on seeds yield. The higher seeds yield (485.) Kg.ha-1 was obtained when alfalfa plants were sprayed with HA at the conc. of 2 cm3.L-1 in vegetative growth.

This investigation was carried out during 4th November 2019 to 20th April 2020 at Grdarasha field, college of Agricultural Engineering Sciences-Salahaddin University, to evaluate the effect of foliar application of the Nitrophenolates biostimulator at different levels (0, 0.2, 0.4, 0.6, 0.8 and 1 ml.l-1)on growth and yield of two Pea cultivars (Utrillo and Nihal). Significant results were obtained from most studied parameters. The results indicated that cultivars had significant response on some of vegetative growth and yield parameters of pea, the best results were recorded from Utrillo cultivar. Moreover, foliar spraying of Nitrphenolates had significant influence on vegetative parameters, the highest significant result of leaves and branchesnumber (110.747 and 2.694 respectively) were recorded from (1ml.l-1). While, the best results of vegetative growth fresh weight and leaf chlorophyll content were obtained from 0.2 ml.l-1treatment. Foliar spray of Nitrphenolate also increased significantly yield parameters, where the highest values of number of seeds.pod-1, yield per plant, plat and hectare (6.000, 0.168kg, 1.009kg and 1.681ton respectively) were recorded from 0.2 ml.l-1 treatment compared with the control. Meanwhile, there was the significant response of cultivars to foliar application of Nitrophenolates on most vegetative growth and yield components and were recorded for both cultivars especially Nihal.

The present study was carried out during growing season of 2018-2019, in the wooden canopy of the College of Agricultural Engineering Sciences, University of Duhok, Kurdistan Region of Iraq, to investigate the influence of foliar spray of four concentrations of Urea (0, 0.5, 1 and 1.5 g.L -1 ) and inoculation the soil with Azotobacter at two concentrations (0 and 10 m.L -1 ) and their interaction on the vegetative growth properties and quality of strawberry plant cv. Rubygem. The results indicated that Urea and Azotobacter significantly increased vegetative growth (chlorophyll, fresh weight, leaf area, leaf number and dry weight) as well as fruit quality (fruit weight, fruit length and number of fruits) (15.4g, 5.58cm and 10.67) respectively as compared with untreated plants. The interaction between the studies factors varied in their effect on the traits. The best interaction was the interaction of Urea at concentration (1g.L -1 ) and Azotobacter at (10 m.L -1 ) which gave the highest values (45.17 SPAD, 15.84 g and 5.38g) respectively as compared with other plants.

A research was carried out in the lath house of the College of Agricultural Engineering sciences / University of Baghdad / Al-Jadriyah, for three growth seasons Spring 2017, Fall 2017 and Spring 2018 to study the effect of different fertilization methods, were Fertigation (Ft) , Foliar application (Fa), traditional soil fertilization (Fo) and growth stimulant with two concentrations 0 (D0) and 1.5 mg.L-1 (D1) on the growth of local Citrus limon L. Saplings grafted on Citrus aurantium L. (So), C. volkameriana (Vo), and Citrumello (Co). Saplings were cultivated in 10 kg plastic containers. A factorial experiment was carried out according to the Nested-Factorial Experimental design. Results indicated foliar application (Fa) superiority, followed by Fertigation (Ft) in plant height, rootstock and scion diameter, while the number of shoots increased significantly using (Ft). Lemon trees grafted on (So) showed superiority in plant height, while trees grafted on (Vo) recorded higher rates in rootstock, scion diameter, and shoot number. Plants fertilized with (Fa) surpassed in nutrient use efficiency (NUE) of N, P, K they were 1.18, 0.43 and 1.30 g.dw -1, respectively. (Vo) indicated highest value in (NUE) of N, P, K elements in plants (1.32, 0.48 and 1.45 g. dw -1) in comparison to So and Co. The Fa * Vo * D0 treatment increased significantly rootstock stem diameter (73.15 and 126.03%), while the highest rate in plant height was recorded by Fa * So* D0 (111.19%.) The highest increase rate of shoot number (483.9%), was by Ft * So * D1. The treatment Fo * Co * D1, gave the highest carbohydrate (4.92%).

This study was aimed to estimate the influence of Conocarpus erectus L. residues, and some micronutrients on growth and production of potato. This research was conducted at one of the fields of the College of Agricultural Engineering Sciences - University of Baghdad. The experiment was implemented using factorial arrangement (4X3X3) within randomized complete block design with three replicates. Conocarpus fertilizer was represented the first factor with three levels (7.5, 15, 30 ton.ha-1), which symbolized (C2, C3, C4). Mineral fertilizer as recommended dose as a control, which symbolized (C1). The second factor was foliar spraying with three levels of iron (0, 100, 200 mg.L-1), which symbolized (F0, F1, F2). The third factor is foliar spraying with three levels of boron (0, 50, 100 mg.L-1), which symbolized (B0, B1, B2). Results revealed that the treatments C1 and C3 produced significant results in most of studied traits such as, Leaves number (71.74, 82.26 leaves plant-1), leaves chlorophyll content (223.30, 174.11 mg 100g wet weight) and total yield (84.24, 51.98 ton h-1) for both seasons respectively, while C1 and C4 produced the most significant protein percent reached (7.53, 7.71%) respectively. The foliar application of Fe at F2 produced the highest results in leaves number (70.47, 80.18 leaves plant-1), protein percent (7.40, 7.55%) for both seasons respectively, Also the foliar application of Boron at B1 and B2 produced a significant results in leaves number (68.58, 78.71 leaves plant-1), total yield (48.47, 76.00 ton h-1), and protein percent (7.43, 7.49%) for both seasons respectively. Furthermore, the third order interaction at the treatment C3F2B2 produced the highest protein percent (7.78%) in spring season only.
