Wheat is one of the most important cereal crop and staple foods in the world. Increase in productivity of wheat by balance nutrient management is one of the most crucial factors. The main objective this study is to assessing the role of micronutrients in improving different components of wheat yield. There are different methods of application such as seed priming, soil application and fortification but foliar application is more beneficial. This is due to response of foliar application has positive and quadrate in nature i.e. the optimum dose of foliar application of zinc for grain yield of wheat was observed as 0.04%. Among treatments of micronutrient alone or combined forms give better results over control. Results have show that micronutrient application substantially improved leaf area index (LAI), leaf area duration, CGR (Crop growth rate), RGR (Relative growth rate), NAR (Net assimilation rate), plant height, spike length, spikelets/spike, grains/spike, test weight, tillers m-2, grain yield, chlorophyll content and biological yield as well as harvest index of wheat. The yield and quality of wheat products improved and boosted by micronutrient applications. Therefore, human and animal health will be protected with the feed of enriched and balanced nutrition of produce as well as it will help in facing the severe global food security.

Two field experiments were conducted under field conditions under a sprinkler irrigation system in the West desert of Iraq, Al-Qaim Area, 400 km west of Baghdad. Underground water was used as a source of irrigation water to study the effect of different rates and different times of boron application on wheat cv. Ibaa99. RCBD with five treatments and three replications was used in this study. Boron dose was 2 kg/ha for soil application method and 0.30 kg/ha for foliar application method. Boron treatments were: 0 (control T1), 2 kg B ha-1 at sowing time (T2), 2 kg B ha-1 at 30 days after sowing (T3), 0.3 kg B ha-1 foliar application at 60 days after sowing (T4) and 0.3 kg B ha-1 for foliar application at 90 days after sowing (T5). Most boron treatments gave a significant increase as compared with control in morphological, physiological and productivity characters of wheat crop. The results revealed that B application treatment at 30 days after sowing time increased significantly the 1000 grains weight (17.6%) while T5 treatment increased significantly the chlorophyll content (12.41%) over control. In most cases, B application treatment at 60 days after sowing time showed the best results and increased significantly the plant height (5.24%), leaf area (9.18%), number of grains spike-1 (30.9 %), number of spike m-2 (18.8%), spike length (65.6%), Grains yield (34.6%) over control. There was evidence that the best dose of boron was 0.3 kg B ha-1 and the best time of B application to the foliage was at 60 days after sowing.

Aspirin (Acetylsalicylic acid) is an important signal molecule modulating plant responses to stress. Drought significantly decreased the growth rate and impaired the yield of wheat. Acetylsalicylic acid can improve the performance of wheat under both well-watered and drought conditions. Applying salicylic acid at a relatively low concentration positively impacted the physiological, yield, and growth parameters. In order to determine the effect of foliar application of Aspirin levels on growth, yield, and its components of wheat, two experiments, i.e., control and rainfed, were conducted to evaluate the effect of salicylic acid were carried out at glasshouse of Research Area, Department of Agronomy and university research farm Koont of PMAS-Arid Agriculture University Rawalpindi during cropping season 2019-20. Four treatments of Aspirin (Control, 120 mg/L, 180 mg/L, and 240 mg/L) for glasshouse (Control, 20 g/L, 30 g/L, 40 g/L) for rainfed were applied, which are to be known as As0, As1, As2, and As3 for both experiments. Foliar application of Aspirin solution sprayed at growth stage 37 on the Zadoks scale. Results of experiments revealed that for the 180mg/L of Aspirin (As2), improved growth parameters such as plant height, spike length, number of spikelets, and increased the wheat crop yield. In contrast, for the rainfed experiment, the plant height, spike length, number of spikelets, and increased yield were observed by applying 30 g/L (As2) of Aspirin, and the lowest results of these parameters were recorded in control treatment for both control and rainfed experiments. The overall results of this study showed that among the levels of Aspirin, the application of treatment As2 both for control and rainfed experiment, i.e., 180 mg/L for control and 30 g/L for rainfed Aspirin, have positively impacted the growth and yield parameters of wheat and bought improvement in wheat production under plant stress environment.

Aphids are the most important pests on wheat in Egypt and worldwide. Field trials were conducted to assess the efficacy of the neonicotinoid insecticides imidacloprid (Nufidor 60% FS; at the doses of 2.1, 1.05 and 0.525 g a.i./kg of seeds) and thiamethoxam (Cruiser 70% WS; at the rates of 14.4, 7.2 and 3.6 g a.i./kg of seeds) as seed treatments, and thiamethoxam (Actara 25% WG; at the rates of 0.1, 0.05 and 0.025 g a.i./l) as foliar application, against three wheat aphids: bird cherry oat aphid, Rhopalosiphum padi (L.), greenbug, Schizaphis graminum (Rondani), and corn leaf aphid, Rhopalosiphum maidis (Fitch). Their effects on the aphids? natural enemies: lacewings, Chrysoperla carnea Stephens, ladybird beetles, Coccinella spp., and syrphid flies Syrphus spp. were assessed as well. The trials were conducted on the farm of the Faculty of Agriculture, Suez Canal University, Ismailia Governorate, during 2013/14 and 2014/15 seasons. Our results showed significant differences between the tested insecticides at all concentrations and clearly indicated that the recommended doses of all insecticides were more efficient against aphids on wheat plants than half- and quarter-doses. Also, the data revealed significant differences between the two seed treatments at all doses before and after foliar application, as compared to the control at all time intervals of inspection regarding the mean number of aphids on wheat plants, from the 3rd until 13th week after sowing, except in the 8th week after seed treatment before foliar application. The results clearly indicated that the weekly reduction of infestation and the general efficacy was higher at the recommended doses of Nufidor, Cruiser and Actara than the half and quarter doses in both seasons. Also, reduction in infestation decreased over the following weeks until the 8th week, when Actara insecticide was sprayed. Data revealed that there were no significant differences between treatments and control in the mean number of Chrysoperla carnea and Syrphus spp., while a significant difference in the mean number of coccinellids was observed on wheat plants treated with imidacloprid seed treatment before foliar application 6 and 7 weeks after sowing, and also after foliar application with thiamethoxam 9, 10, 11, 12 and 13 weeks after sowing. Regarding thiamethoxam seed treatment, significant differences were revealed in the ladybird population on wheat plants 3, 4, 7 and 8 weeks before foliar application, and only in the 10th week after spraying with thiamethoxam.

Abstract Two field experiments were carried out in two successive seasons to examine the effect of weed management on wheat crop under saline condition and how herbicides can interact with foliar application with indole-3-acetic acid (IAA) to improve weed suppression and enhance crop growth and productivity under salinity stress. Clodinafop-propargyl was the best option to attain acceptable grassy weeds control. Increasing IAA from 0 up to 150 ppm significantly increased number and dry weight of grassy weeds in wheat after 80 days from sowing. Application of IAA at 150 ppm recorded the highest number and dry weight of weeds. Clodinafop-propargyl produced the lowest values of number and dry weight of weeds as well as nutrients uptake by weeds when water spraying was added. While application of IAA at 150 ppm gave the maximum values of flag leaf area, SPAD meter values, number of spike/m2, spike length, number of spikelets/spike, grains number/spike, grains weight/spike, as well as grain, straw, and total crude protein, phosphorus and potassium percentages when clodinafop-propargyl treatment was applied. It could be concluded that using IAA at 150 ppm resulted in enhancement of growth and productivity of wheat crop when integrated with clodinafop-propargyl treatment under salinity condition.

Lodging in plants is an important constraint that leads to yield losses and cause problems with mechanical harvesting. This research was aimed at determining the effects of foliar application of uniconazole or ethephon on lignin metabolism, characteristics of second basal internode and their relationship with lodging resistance in winter wheat (Triticum aestivum L.). In separate experiments, uniconazole was sprayed on the foliage at concentrations of 0, 15, 30 and 45 mg L–1, and ethephon at concentrations of 0, 50, 75 and 100 mg L–1 at the four-leaf stage. Foliar application of uniconazole or ethephon significantly reduced the lodging rate by increasing the lignin content and optimising basal-internode characteristics. Lignin content was significantly positively correlated with breaking strength, and negatively correlated with lodging rate, whereby the higher lignin content in the second basal internode significantly improved the lodging resistance and reduced the lodging rate in the wheat crop. Foliar application of uniconazole or ethephon also increased the breaking strength, internode diameter, wall thickness and internode plumpness of the second basal internode; maximum values were obtained with uniconazole at 30 mg L–1 and with ethephon at 75 mg L–1. Grain yield, lignin content and lignin-related enzyme activities of phenylalanine ammonia-lyase, tyrosine ammonia-lyase, cinnamyl alcohol dehydrogenase and peroxidase were all significantly improved with the foliar application of uniconazole or ethephon. These results suggest that lignin content in the second basal internode in wheat was closely related with lodging resistance. Foliar application of uniconazole or ethephon at the four-leaf stage reduced the lodging rate, and the concentration showing the greatest effects was 30 mg L–1 for uniconazole or 75 mg L–1 for ethephon.

ABSTRACT Wheat is a major winter crop in southern Brazil. To maximize its productivity, there should be no biotic or abiotic restrictions that can affect the yield components. Thus, the objective was to evaluate the changes caused in the wheat crop yield components by silicon foliar application. The experiment was conducted in two growing seasons. In the first year, five wheat cultivars (Quartzo, Campo Real, Onix and Fundacep Lineage) were assessed and in the second year four were assessed (Mirante, Campo Real, Horizonte and Quartzo). In both years the crops were subjected to three doses of silicon (0, 3 and 6 L of silicon ha -1). The silicon was applied during the tillering, booting and anthesis stages. The yield components assessed were the number of plants, number of ears, number of fertile tillers, dry matter per plant, hectoliter weight, number of spikelets, number of grains per spike, weight of hundred grains, grain yield and harvest index. Most yield components did not respond to the silicon foliar application. The harvest index (first year) and the number of tillers (second year) however presented a quadratic relationship with the supply of silicon. The remaining differences were attributed to variations among the wheat cultivars.

AbstractPaddy-wheat crop rotation is responsible for declining soil health, underground water table, arising new micronutrient deficiencies, new weed flora, and resistance to herbicides, declining both land and water productivity and is claimed to be capital and energy-intensive, more particularly in emerging countries. This is further aggravated when micronutrients are deficient, particularly zinc (Zn), which plays an important role in human health, especially in developing countries. Zn biofortification is a technique in which the inherent Zn status of the edible portion of plants is improved by simply spraying a Zn solution onto the crop or through a soil application at a predetermined stage and a proper dose. The concentration of Zn within a wheat grain is genotype-dependent and interacts with the environment, inducing variation in a grain’s concentration of micronutrients. Grain quality parameters are positively correlated with a higher dose of nitrogen in the late reproductive stage. Broadcasting of ZnSO4·7H2O at 62.5 kg ha−1 and foliar application of Zn chelates such as Zn–HEDP (C) at 2 g L−1, Zn–HEDP (L) at 3 g L−1, or a 0.4–0.5% ZnSO4 solution during grain development stage enhanced the growth, productivity, and micronutrients concentration in the edible portion of the plant which further improves the quality of wheat grains and ultimately improves human health in the region. Given the central importance to Zn in cereal-based nutrition, zinc biofortification appears as an innovative technology to alleviate the zinc deficiency in human health, especially on the Indian subcontinent, by applying Zn either as a foliar or soil application.
