In order to evaluation of application method efficiency of zinc and iron microelements in canola, an experiment was conducted in the Agricultural Research Station of Eastern Azerbaijan province in 2008. The experimental design was a RCBD with eight treatments (F1: control, F2: iron, F3: zinc, F4: iron + zinc in the form of soil utility, F5: iron, F6: zinc, F7: iron+ zinc in the form of solution foliar application, and F8: iron + zinc in the form of soil utility and foliar application). Analysis of variance showed that there were significant differences among treatments on given traits, antioxidant enzymes activity, fatty acids percentage, plant height, seed weight to capitulum weight ratio, protein percentage, oil percentage, oil yield, 1000 seed weight, seed yield, nitrogen, phosphorous and potassium percentage of leaves, zinc and iron content of leaves and capitulum diameters. The highest seed yield, oil yield, oil percentage, 1000 seed weight, seed weight to capitulum weight ratio and protein percentage were obtained from the soil and foliar application of iron + zinc treatments (F8). Also, the highest amounts of nitrogen, phosphorous and potassium concentration in leaves were achieved from control treatment which was an indication of non-efficiency of iron and zinc on the absorption rate of these substances in the leaves. The correlation between effective traits on the seed yield, such as, capitalism diameter, number of seed rows in capitulum, seed weight to capitulum weight ratio and 1000 seed weight were positively significant. In general, foliar and soil application of zinc and iron had the highest efficiency in aspect of seed production. The comparison of the various methods of fertilization showed that foliar application was more effective than soil application. Also, micronutrient foliar application increased concentration of elements, especially zinc and iron. Antioxidant enzymes activity was different in response to treatments also the highest palmitoleic, oleic and myristic acid were observed in F6 and F7 treatments.

Half F2 diallel crosses of six spring cultivars of rapeseed (Brassicanapus L.) were used to estimate heterosis effects of yield components, seed yield, oil percentage, and oil yield under limited nitrogen condition. Significant mean squares of general and specific combining abilities (GCA and SCA) were detected for pods per main axis, pods per plant, length of pod, seeds per pods, 1000-seed weight, seed yield, and oil content and oil yield indicated respectively the importance of additive and non-additive genetic effects for these traits. High narrowsense heritability estimates for 1000-seed weight, oil percentage, and oil yield indicating the prime importance of additive genetic effects for these traits. Most of the cross combinations with significant positive heterobeltiosis for seed yield had also significant heterobeltiosis effects for pods per plant and pods on main axis; therefore these traits can be used as indirect selection criteria for improving seed yield. Significant positive correlation of mean performances with heterosis and heterobeltiosis effects for most of the traits except 1000-seed weight indicated that selection of the superior crosses based on heterosis and heterobeltiosis effects will be effective for their mean performances improving these traits except 1000- seed weight. Significant positive correlation was determined between pods per plant and seed yield, indicating that this trait can be used as good selection criterion for seed yield improvement. The crosses including RAS-3/99 × RW-008911 and RAS- 3/99 × RGS-003 with high significant positive heterobeltiosis effects of seed yield were superior combinations for seed yield increasing.

The study was aimed at identifying the amount of reduction in the negative effects of leaf removal on both quality and quantity of sunflower as a result of foliar application of Fe and Mn. Severe leaf removal reduced the seed yield and seed weight to 11% and 10.5% respectively. The use of Fe in comparison to control increased the seed yield and seed weight up to 12% and 10% respectively. The use of Mn in comparison to control caused an increase in seed number up to 11.6% but caused a reduction in seed weight to 10%. The use of Fe in normal foliar defoliation treatment (40% defoliation) caused a significant increase in seed yield but no significant effect was observed in sever defoliation treatment (80% defoliation). Although using Mn in all treatments led to a rise in seed yield, the effect was not significant, it could be concluded that the combined use of Mn and Fe had no significant influence on sunflower yield, so there might be an antagonistic effect between the two.

The comparative effect of 0, 0.2, 0.4, 0.6 and 0.8% Zn levels of zinc chelate (Zn-EDTA; 8% Zn) and zinc sulfate (23% Zn) applied as foliar sprays for assuaging zinc deficiency of chickpea cv. Gökçe was evaluated under field condition. The sprays were applied on the plants before blooming stage during 2012 and 2013 growing seasons and seed yield, yield components like plant height, pod number per plant, seed number per plant, hundred seed weight, harvest index and mineral concentrations (nitrogen, phosphorus, zinc and iron) in seeds were investigated. Plant height, pod number per plant, seed number per plant, hundred seed weight, harvest index and seed yield were investigated. The results showed that increased zinc doses caused an increase in Zn content of seed, while seed yield was not affected similarly. In general, plant height, pod number and seed number per plant increased by the application of zinc. Lower dose of Zn-EDTA and higher dose of ZnSO<sub>4</sub> gave higher yield components. Seed weight, harvest index and seed yield were not significantly influenced by Zn sources and doses; however, mineral concentration of seeds enhanced when Zn doses were increased. It was concluded that foliar application of zinc resulted in an increase in seed mineral contents rather than seed yield of chickpea. The dose of 0.6% with Zn-EDTA was the optimum combination for Zn enrichment in seed of chickpea.

A field experiment was conducted during rabi season of 2015-2016 at Navsari Agricultural University, Navsari to study the impact of cobalt application methods on chickpea yield, nutrient content and soil status. Four cobalt application methods with three levels of each were evaluated with one absolute control and one with seed priming of water were evaluated with randomized block design with three replications. Least level of seed treatment, soil application and foliar application of cobalt gave highest chickpea seed yield and decreased there after. As cobalt levels increased, NPK content and uptake are decreased linearly in all the methods except seed priming method, however cobalt content and uptake increased linearly by seed treatment and foliar application, on the contrary it decreased linearly by seed priming and soil application of cobalt. Soil application of cobalt at 50 g ha-1 recorded highest chickpea seed yield, residual NPK and Co and which can be useful for succeeding crop and this can be recommended from the cobalt nutrition point of view in plants and animals followed by seed priming at 1 ppm.

SUMMARYThe change in seed oil percentage and 100-seed weight of Brassica juncea Varuna was studied as the crop matured during rabi 1977–78. Statistically, the oil percentage reached its highest value at 55 days from flowering, whereas the 100-seed weight was highest about 20 days later, when the pods were fully yellow. Oil yield (the product of oil percentage and seed weight) also reached its highest value when the pods were fully yellow. This information should enable the crop to be harvested at the proper physiological stage (yellow-podded) for maximum oil yield.

The sowing date is an important factor for expanding the cultivated area of rapeseed and affects seed yield, oil content, and fatty acid compounds. Micronutrient elements play an important role in improving the vegetative and reproductive growth of the plant, especially under conditions of biological and environmental stresses. A two-year experiment (2014-2016) was performed to study the response of rapeseed genotypes to foliar application of micronutrients on different sowing dates. The treatments were arranged as a factorial-split plot in a randomized complete block design with three replicates. Three sowing dates of 7 (well-timed sowing date), 17, and 27 (delayed sowing dates) October and two levels of foliar application with pure water (control), selenium (1.5%), zinc (1.5%), and selenium+zinc (1.5%) were factorial in the main plots and five genotypes of SW102, Ahmadi, GKH2624, GK-Gabriella, and Okapi were randomized in the subplots (a total of 30 treatments). Seed yield, oil yield and content, oleic acid, and linoleic acid were reduced when rapeseeds were cultivated on 17 and 27 October, while the contents in palmitic, linolenic, and erucic acids, and glucosinolate increased (p < 0.01). a selenium+zinc treatment improved seed yield, oil content and yield (p < 0.01). The oil quality increased due to increased contents of oleic and linoleic acids under the selenium+zinc treatment (p < 0.01). The GK-Gabriella and GKH2624 genotypes are recommended to be sown on well-timed (7 October) and delayed sowing dates (17 and 27 October) and treated with selenium+zinc due to the higher oil yield, linoleic and oleic acids.

A filed experiment was conducted at Ehssay village-Amria-Fallujah district in Al-Anbar governorate during the spring season of 2012 and 2013 in order to study the effect of potassium fertilizer and foliar nutrition of iron and zinc on yield and its quality of two mung bean (Vigna radiata L.) genotypes. Factorial arrangement was used in RCBD with three replicates. The experiment included three levels of potassium (0, 60 and 120) kg K.ha-1, four treatments of foliar application of zinc and iron (0, Fe 150, Zn 100 and Fe 150 + Zn 100) mg.L-1 and two mung bean genotype (Local and Indian VC6089A10). The local genotype gave the highest rate of the number of pods (32.13 and 36.28) pod.plant -1and seed yield (573.0 and 601.8) kg.ha-1, while the indian genotype was superior in weight of 100 seed (6.66 and 7.29) gm for both seasons respectively. The level 60 kg K.ha-1 of potassium gave the highest average of seed yield (635.4  and 663.6) kg.ha-1, while the level 120 kg.ha-1 gave heighest average of number of seeds per pod (7.6 and 7.5 seed.pod-1) and protein percentage (26.18 and 25.82)% for the two seasons respectively. The concentration of Fe 150 mg Fe.L-1 and Fe + Zn (Fe 150 + Zn100 mg.L-1) recorded highest values for most of yield traits for both seasons. The foliar application of Fe gave seed yield (583.0 and 576.8) kg.ha-1, while foliar application of Fe+Ze gave highest average of seed per pod (7.6 and 7.2) seed.pod-1 and percentage of protein (27.17 and 27.11)% for both seasons respectively. A significant interaction between genotypes and potassium levels, the local genotype with 60 kg K.ha-1gave the heighest average of the number of pods (39.22 and 41.61) pod.plant-1 and seeds yield (703.6 and 756.9) kg.ha-1 for both seasons respectively, so the interaction between local genotype and concentration (Fe150 + Zn100) mg.L-1 gave the highest average of number of pods, number of seeds per pod and protein percentage for the first seasons only. The interaction between the level 60 kg K.ha-1 of potassium and the concentration Fe150 mg.L-1 from the foliar nutrition of iron showed significant superiority in seed yield (754.9 and 759.5) kg.ha-1 for both seasons respectively. The triple interaction was significant in most of traits under study, the local genotype that fertilized with 60 kg K.ha-1 and sprayed with Fe 150 + Zn 100 mg.L-1 gave highest average of seed yield (886.7 kg.ha-1) in the second season only.

Background. An insufficient amount of nutrients in plants results in the disturbance of basic physiological processes, weakens the growth and development of plants, and consequently contributes to a reduction in yield. The aim of this study was to determine the effect of foliar fertilizers containing sulphur, boron and amino acids on the seed yield of three winter oilseed rape morphotypes (Monolit, PX115, PT248).Material and methods. The study was carried out in 2016-2019 at the Zawady Agricultural Experimental Station (52o03' N; 22o33' E) belonging to the University of Natural Sciences and Humanities in Siedlce, in Poland. The field experiment was established in a split-plot design with three replicates. The studied factors were: I – three winter oilseed rape morphotypes: population (cv. Monolit), restored with the traditional growth type (cv. PT248), and restored with the semi-dwarf growth type (cv. PX115); II – types of foliar feeding: 1. The control variant – without foliar feeding and amino acids applied, 2. biostimulant Aminoplant, 3. foliar fertilizer Siarkomag + foliar fertilizer Bormax, 4. foliar fertilizer Siarkomag + foliar fertilizer Bormax + biostimulant Aminoplant.Results. Foliar fertilizers used in the experiment increased the thousand seed weight (on average in the range from 0.9% to 3.4%), seed yield (on average in the range from 2.5% to 18.5%), straw yield (on average in the range from 2.1% to 5.4%) and the harvest index (on average in the range from 4.4% to 7.5%). Of the compared cultivars the semi-dwarf cultivar (PX115) was characterized by the highest yield, while the lowest was from the population cultivar (Monolit). The highest thousand seed weight, main and secondary yields were obtained in the first year of the study which was characterized by a higher total rainfall during seed development and maturation of pods periods compared to the multi-year period, while the lowest levels of these factors was in the vegetation season of 2017–2018 with a humid autumn season and dry period during the flowering and maturation of pods.Conclusion. The most significant increase in the thousand seed weight and seed yield was obtained after applying mixed fertilizers containing sulphur, boron and amino acids. Additional foliar application of the biostimulant Aminoplant on plots with the population and semi-dwarf cultivars did not significantly increase the seed yield as compared to the control. A significant effect of the genetic factor and climatic conditions on the discussed traits has been demonstrated.

ABSTRACT The growing use of chemical fertilizers, insecticides and pesticides can cause potential contamination with heavy metals to soil and groundwater, posing environmental and health threats. Heavy metals can also affect crop yield. A greenhouse experiment was conducted to explore the role of ascorbic acid foliar application and soil-applied super absorbent to mitigate adverse effects of cadmium (Cd), in terms of biochemical parameters in wheat. The experiment was installed in a completely randomized design, with treatments arranged in a factorial scheme with three levels of super absorbent polymer (0 g kg-1, 4 g kg-1 and 8 g kg-1 of soil) by three levels of ascorbic acid (0 mM, 50 mM and 100 mM), with four replicates. The Cd contamination caused a significant increase in the accumulation of Cd in leaves and seeds, as well as in antioxidant enzymes activity and lipid peroxidation. It also decreased seed weight and chlorophyll content in wheat plants. The super absorbent increased seed yield (22.68 %), seed weight (19.31 %), chlorophyll (27.97 %) and ascorbic acid content (65.51 %), while it reduced the Cd accumulation in leaves (34.27 %) and seeds (32.97 %), as well as antioxidant enzymes activity and lipid peroxidation (43.77 %). Similar results were found when ascorbic acid was applied. Ascorbic acid increased seed yield, seed weight and chlorophyll content by 12.62 %, 17.66 % and 13.17 %, respectively. As a result, the super absorbent polymer and ascorbic acid could improve the survival capacity and yield of wheat plants in response to Cd contamination in the soil.
