Abstract: The aims of the experiment are to determine and understand the effect of genotype, environment, and their interaction on grain yield of tef, and to identify and release stable and high yielding tef genotype for high potential areas of country. Twelve tef genotypes including two checks were laid out in randomized complete block design using four replications for two years (2016 and 2017) at twelve representative locations of high potential areas of the country. The trial was conducted on the plot size of 2m*2m with 10 rows per plot throughout all trial sites and 1.5m between replication, 1m between plot, and 20cm between rows. Agronomic and yield data were collected and subjected to statistical analysis in order to identify the best genotypes of the evaluated genotypes. Data from individual environments and combined over twelve locations were analyzed by using R 3.5 software version. The combined data analysis over locations and years indicated that the candidate variety Kaye Murri X 3774-1 (RIL18) performed better than the two checks and the other test genotypes. It gave 7.5% and 10.65% grain yield advantages over the standard check (Quncho) and local check, respectively. The significant genotypes x environments interaction effects indicated the inconsistent performance of genotypes across the tested environments. The candidate variety DZ-Cr-458 (RIL18) is the shortest vector from the AEC axis that identified as the most stable genotype. The National Variety Release Committee in Ethiopia investigated the two-year performance of Kaye Murri X 3774-1 (RIL18) and visited several locations where the new candidate variety was grown for evaluation under variety verification trial. Based on the critiques, the National Variety Release Committee the candidate variety was approved for release Kaye Murri X 3774-1 (RIL18), for high potential areas of the country with the vernacular name of “Ebba” as a standing witnessed for the earliest known tef scientist, Dr. Tadesse Ebba.

Abstract: In the present study, a field experiment was conducted to study the effect of tomato tone organic fertilizers on tomato for its growth and yield of tomato. A field experiment was performed in wagan city, larkana, sindh, Pakistan, during the period from April 2021 to October 2021 to quantify the effect/impact of Tomato tone on growth and yield of summer tomato. The experiment consisted of two level of the Tomato tone viz. H0: no Tomato tone (H1) 2% Tomato tone. The test became laid out in the randomized entire block design with two replications. Outcomes found out that the tremendous variant was found for the special increase contributing characters of summer season tomato due to tomatotonse. The longest plant about (72.1cm), greatest number of leaves (49), greatest number of flowers/plant (9.9), The very best duration of fruit (4.9 cm) found from the (H1) Highest wide variety of the end result/plant (39.1), and the best yield/plant (4.2 kg) And the best yield (21.8 t/ha) turned into found from (H1). Alternatively, the lowest plant peak, or lowest yield, and the lowest wide variety of leaves, flower and end result was observed from the H0 (control).

Abstract: Wheat production in Ethiopia in the year 2020 was around 5.1 million metric tons (World data Atlas, 2021). Although the country has the potential optimum environment for wheat production, the deficit between wheat grain production and national demand is about 1.7 million tons of wheat per annum. It is about 25% of total consumption. That is mainly due to biotic and abiotic stress threatened production results in low productivity. Wheat rust fungal pathogens are among the production constraints in Ethiopia. The national wheat research program objectively works on the development and release of resistance bread wheat variety for wheat rusts with high grain yield and good quality. In 2018 and 2019, twenty-three advanced genotypes and two checks; as a whole twenty-five entries, set as Bread Wheat National Variety Trial for Moisture Stress Areas set one (BWNVTMSAI) by the National Wheat Research Program and evaluated across different locations. The experiment was conducted in a square lattice design with three replications by the program. The experimental unit had 2.5 m length by 1.2m width was used for this trial with an area of 3m2. In 2020 two promising bread wheat candidates, ETBW9396 and ETBW9080, those selected from the National Variety Trial, One standard check Daka, and one local check Kakaba, a total of four materials tested as a Variety Verification Trial (VVT) with no design and replication across four locations. Results showed about twelve genotypes have a greater than 5% grain yield advantage over the best check, Deka (Table 2). ETBW9080, ETBW9172, and ETBW9396 showed better performance for wheat rust disease (Table 3). The National Wheat Research Program selected and proposed ETBW9080 and ETBW9396 as candidate varieties. The National Variety Releasing Committee (NVRC) met its first round at Adiss Ababa in the Ministry of Agriculture in June 2021. The standing committee decided to release ETBW9636. Then. ETBW9636 registered as a new bread wheat variety in 2021 in Ethiopia. Replacement of susceptible bread wheat varieties and availing more alternatives bread wheat varieties to grow for resource-poor farmers is very crucial in the region.

Abstract: Field pea (Pisum sativum L.) variety named Mieso with the pedigree designation of Acc 32003-2 has been officially released by Sinana Agricultural Research Center in 2021. The variety is best adapted to altitudes ranging between 2300 to 2600 meters above sea level in the country. Mieso variety evaluated along sixteen Field pea genotypes including the standard check “Harena and T/Shenene” under a regional variety trial for three years (2016 to 2018) at Sinana, Sinja and Agarfa districts. Promising genotype, “ACC32003-2” were selected and promoted to variety verification trail with the standard check during the 2020/21 cropping season. Finally, the National Variety Release Technical Committee decided “ACC32003-2” genotype for release. This Field pea variety showed superior performance particularly in terms of productivity and resistance/ tolerance level to disease across the years and locations. The released variety out-yielded the other tested Field pea genotypes on both research plots and farmers’ fields. Based on most stability parameters, Mieso showed relatively better grain yield performance (3570kg/ha) and stability across a range of environments and years than the standard checks (Harena and Tulu Shenene) and could be cultivated across a number of locations in the highlands of Bale and other similar agro-ecologies for increasing productivity of the crop.
