Bread wheat (Triticum aestivum L.) is the most important cereal occupying a protruding position among major food crops in the world in terms of acreage and production and is an important cereal crop which is receives the most attention of specialists in plant breeding and production in the world wide in general and in Ethiopia in particular. And also a number of improved bread wheat varieties have been released by different research centres for different agro-ecology in Ethiopia. Evaluate the performance of different bread wheat varieties at diverse agro-ecology is an important for effective selection of the variety. This experiment was conducted on ten bread wheat varieties against local check (Digalu) at Meskan and Dalocha wereda with the objective of identify and recommend high performance in terms of yield, insect pest tolerant, and stable varieties. The varieties were assigned in randomized complete block design with four replication. Data were collected on six major agronomic traits. Based on the mean separation, the highest average grain yield was recorded from Hidasse and Ogolcho varieties with 5210 and 5080 kg/ha respectively. However the lowest average yield (3220kg/ha) was recorded from Digalu variety. In both locations Digalu variety provided the lowest yield due to high susceptibility for stem rust. Statistically, the variety Hidasse gave the highest number of tillers per plant and the tallest spikes length at both locations those are positive contributions to grain yield. There were significantly positive and negative correlations between traits. In this study, it is found that there is 38.19% increment of yield for using Hidasse variety (high yielder) as compared to Digalu variety (low yielder) at the study area. Therefore, farmers located at the study areas are recommended to use Hidasse variety to increase bread wheat yield.

Fertilizer Rates

Wheat is the most important cereal crop ranking 4th in total grain production and area coverage in Ethiopia. However, its productivity is low compared to the yield obtained under the research station. Multinutrient deficiency, low/no chemical fertilizer usage, and poor management practices are among the major constraints. Thus, response of bread wheat to NPS and K fertilizer rates was evaluated in the nitisols at Kokate, Wolaita Sodo, Southern Ethiopia, in 2016. Four rates of KCl (0-0-60) (0, 25, 50, and 75 kg·ha−1) and five blended NPS (19N-38P2O5-7S) rates (0, 50, 100, 150, and 200 kg·ha−1) were investigated using randomized complete block design with factorial arrangement involving three replications. Soil physical and chemical properties, crop phenology, growth parameters, yield components, and yield data were collected. Analysis of variance showed that crop phenology, productive tillers, and straw yield were significantly affected by KCl and NPS fertilizer rates; however, most of growth parameters, yield components, grain yield, and agronomic efficiency were influenced by the interaction effects of KCl and NPS fertilizers. Combined application of 50 kg·ha−1 KCl and 150 kg·ha−1 NPS resulted in highest growth, yield component, grain yield, agronomic efficiency, and economic return, whereas the lowest measured values were recorded from unfertilized plots. The maximum grain yield (4.34 t ha−1) that was recorded from 50 kg·ha−1 KCl and 150 kg·ha−1 NPS was 8.86-fold higher than the minimum yield (0.44 t ha−1) from the control. It is concluded that 50 kg·ha−1 KCl and 150 kg·ha−1 NPS are suggested for better agronomic and economic performance of wheat. As NPS was tested in the blended form, the individual and interaction effects of nutrients under investigation are suggested as future research areas. Additional investigation over season and location is also recommended.

AbstractBread wheat (Triticum aestivum L.) is one of the most important cereal crops in Ethiopia. The productivity of wheat is markedly constrained by nutrient depletion and inadequate fertilizer application. The experiment was conducted to study the effect of nitrogen (N) and potassium (K) fertilizer rates on growth, yield, nutrient uptake and use efficiency during 2019 cropping season on Kedida Gamela Woreda, Kembata Tembaro Zone Southern Ethiopia. Factorial combinations of four rates of N (0, 23, 46 and 69 kg Nha−1) and three rates of K2O (0, 30 and 60 kg Nha−1) in the form of urea (46–0-0) and murate of potash (KCl) (0-0-60) respectively, were laid out in a randomized complete block design with three replications. The results showed that most parameters viz yield, yield components, N uptake and use efficiency revealed significant differences (P < 0.05) due to interaction effects of N and K. Fertilizer application at the rate of 46 N and 30 kg K ha−1 resulted in high grain yield of 4392 kg ha− 1 and the lowest 1041 from control. The highest agronomic efficiency of N (52.5) obtained from the application of 46 kg N ha−1. Maximum physiological efficiency of N (86.6 kg kg−1) and use efficiency of K (58.6%) was recorded from the interaction of 46 and 30 kg K ha−1. Hence, it could be concluded that applying 46 and 30 kg K ha−1was resulted in high grain yield and economic return to wheat growing farmers of the area. Yet, in order to draw sound conclusion, repeating the experiment in over seasons and locations is recommended.

Four advanced tritordeum lines were studied and compared to two commercial varieties of tritordeum and wheat cultivars in yield and quality features, in Greece. For this purpose, a two-year experiment was established in the Greek territory. The field experiment was set up in Randomized Complete Block Design (RCBD) with blocks, with different lines and varieties. Head emergence was calculated based on Growing Degree Days (GDDs), which was significantly affected by the year. The significance of differences between treatments was estimated by using Fisher’s least significant difference (LSD) test with significance level p = 0.05. The weight of 1000 seeds of the two commercial varieties differed from the equivalent weight of 1000 seeds of tritordeum lines, approximately 1 g. Yield was significantly affected by lines/varieties and year. Compared to tritordeum yield, wheat yield marked the highest values. This difference was almost 2 kg ha−1. Gluten content was significantly affected by lines/varieties. The highest gluten content was firstly noticed at wheat GENESIS (34.2%) variety and secondly at tritordeum Aucan (33.2%) variety. Protein was higher in tritordeum lines HT-1704 (15.5%), HT-1707 (15.1%) and Aucan variety (15.2%) during the first experimental year. Tritordeum seems to have significant adaptability to dry conditions in Greece and significant yields compared to the existing commercial varieties and bread wheat.

A field experiment was done for two consecutive years from 2010-11 to 2011-12 with two varieties of wheat (DBW 17 and DPW 621-50) and ten treatments of fertilizer, involving NPK, FYM and micronutrient, with an objective to maximize the crop yield. Results showed that variety DBW 17 recorded significantly higher grain yield (4.93 %), straw yield (6.31%) and HI (1.12%) as compared to DPW 621-50. There was no significant difference in yield attributes between two varieties. Application of 150 % recommended NPK fertilizers produced the maximum grain yield (6.10 t ha-1), which was 7.7 % higher over the 100% NPK fertilizers, followed by 15 t ha-1 FYM application along with 150 (5.98 t ha-1) and 125 % (5.96 t ha-1) NPK application. There had no significant effect of micronutrients (Zn, Cu, Fe & Mn) on wheat yield indicating that the soil was not deficient in those micronutrients. A significant variation was observed between two years in respect of yield and yield attributes, higher performances being recorded in 2011-12. Crop lodging was observed, with a maximum lodging of 26.4 % causing a yield reduction of up to 9.9 %. Agronomic efficiency was the maximum (13.64 kg grain kg-1 fertilizer) with the recommended rate of fertilizers and it decreased with increasing rates. Addition of FYM didn’t increase the agronomic efficiency due to inclusion of 75 kg N contribution from 15 t ha-1 of FYM.SAARC J. Agri., 14(1): 103-110 (2016)

SUMMARYInformation about changes associated with advances in crop productivity is essential for understanding yield-limiting factors and developing new strategies for future breeding programmes. National bread wheat (Triticum aestivum L.) yields in Turkey have risen by an average of 20·8 kg/ha/year from 1925 to 2006. Annual gain in yield attributable to agronomic and genetic improvement averaged c. 11·6 kg/ha/year prior to 1975, but is now averaging c. 15·1 kg/ha/year. In the Mediterranean region, however, the wheat yield trend line (10·9 kg/ha/year) is c. 0·38 lower than that of Turkey. In order to understand whether such a trend was due to the cultivars released over the years, 16 bread wheat cultivars, commonly grown in the region and representing 23 years of breeding, introduction and selection (from 1976 to 1999), were grown in a randomized complete block design with three replicates across 2 years. Data were collected on maturation time, plant height, spike length, spikelet number/spike, grain number/spike, grain weight/spike, 1000 seed weight, harvest index and grain yield. None of the measured plant traits showed any historical cultivar patterns; therefore, the increase in grain yield could not be attributed to a single yield component. Several physiological traits changed during two decades of cultivar releases in the Mediterranean region that led to a genetic gain in grain yield of about 0·5% per year. Years of data and the present field study in the Mediterranean region suggested that the genetic improvement in wheat seemed inadequate and should be reinforced with modern agricultural management practices as well as technological innovations.
