Wheat is a vital crop in Georgia and in the world. Because of the increase in the rate of population growth, improving the grain yield is the way to meet food demand. Proper crop nutrition plays a vital role in maintaining the world’s food supply. Fertilizer is essential for accomplishing this.One of the most important means for increasing the wheat yield is fertilizer, especially, organic fertilizer. The present research was carried out to study the effects of different doses (150ml, 200ml and 300 ml on ha) of humic organic fertilizer “Ecorost” on yield of winter wheat cultivar “Tbilisuri 15”. The humic liquid fertilizer "Ecorost" is a peat-based organic-mineral fertilizer. The product is active and saturated due to the use of the latest technology and living bacteria found in peat. The field trials were conducted in 2017-2019 at the Experimental Site of Scientific Research Center of Agriculture in Dedopliskharo- arid region (Eastern Georgia).Liquid fertilizer was applied two times: in tillering stage in early spring and two weeks after - in stem elongation stage. Results indicated that the highest wheat grain yield (4t/ha) was achieved when the plants were fertilized with 300 ml on 1 ha ofEcorost. Applications of liquid fertilizer “Ecorost” increased grain yield of winter wheat by 16.2% in comparison with standard nitrogen fertilization. Thus, liquid fertilizer “Ecorost” had a significant effect on wheat grain yield compared to control standard nitrogen fertilizer.

A three-year field study in west-central Kansas investigated the effects of combinations of spray carrier, nonionic surfactant (NIS), triasulfuron, and/or 2,4-D on winter wheat foliar injury and grain yield. Herbicides applied in water without NIS caused little or no foliar injury in two of three years. Urea-ammonium nitrate (UAN) at 112 L/ha (40 kg N/ha) alone or as a carrier for herbicides caused moderate to severe foliar injury in all three years. Adding NIS to UAN spray solutions increased foliar injury, especially with the tank mixture of triasulfuron + 2,4-D. Effects of triasulfuron + NIS or 2,4-D applied in UAN were additive. Foliar injury was related inversely to temperature following application. Foliar injury was most evident 4 to 7 d after application and disappeared within 2 to 3 wk. Diluting UAN 50% with water lessened foliar injury in two of three years, especially in the presence of NIS, regardless of whether herbicides were in the spray solution. Treatments did not reduce wheat grain yield in any year despite estimates of up to 53% foliar injury one year.

Effects of fertilisers on the grain yield (t ha-1) and the development of mycobiota, especially of the Fusarium species, in winter wheat kernels were observed. Fertilisers were applied in the following variants: T1 - 30m3 of slurry (pre-sowing treatment) and 25 m3 of slurry (top-dressing), T2 - 22.500 kg of manure (pre-sowing treatment) and 220 kg of urea (top-dressing), T3 - 300 kg of urea (top-dressing) and T4 - the control without application of fertilisers. The average wheat grain yield was the highest in the treatment T2 (6.9 t ha-1), then in T3 (6.3 t ha-1) and T1 (6.2 t ha-1), while the lowest wheat grain yield (4.3 t ha-1) was registered in the control (T4). Fungi of genera Alternaria (88.8-96.3%) and Fusarium (3.7-11.1%) were mainly isolated from all wheat kernel samples collected after harvest (T1-T4). Species of the genus Dreschlera were isolated in treatments T1 (0.3%) and T2 (0.2%). The species Stemphylium botryosum was isolated only in the treatment T1 (0.2%). F. graminearum (3.5-10.8%) was isolated from wheat kernels in all observed treatments, while F. sporotrichioides was isolated in treatments T1 (0.6%), T2 (0.5%) and T3 (0.3%). F. poae (0.3%) and F. subglutinans (0.2%) were isolated in the treatment T2, while F. graminearum was predominantly present in treatments T3 (10.8%), T1 (8.7%) and T2 (7.8%), and in the control T4 (3.5%). The obtained results point out that the application of urea affected the decrease in the intensity of Alternaria species infestation, but it also affected the increase of frequency of Fusarium species, especially F. graminearum, in comparison with the control and other treatments. Negative correlation was registered between the grain yield and the intensity of infestation of Fusarium species (collectively) and F. graminearum (individually).

Abstract. In a series of field trials, a database of quantitative traits associated with winter wheat grain yield has been collected. The aim of the present study is to determine the relationships between the winter wheat (Triticum aestivum L.) traits of productivity in environments causing the maximum possible variation of each of the traits. In order to determine the correlations between the quantitative characters studied, all possible statistical methods have been applied (regression analysis, PCA, Multiple Correspondence analysis), which complement each other. It was found that the nature of the correlations between traits depends to a large extent on the methods for their evaluation. There are high and significant correlations between grain yields and the grain number per spike (weight of grain per spike and number of grains per m2) even under strong genotype by environment interaction of all the traits in trails. The established results are related to possible options for increasing winter wheat grain yield by breeding.
