The present study was conducted to assess seed rate (SR) and nitrogen rate (NR) effects on nutritional quality of oat (Avena sativa L.) at Sirinka Agricultural Research Center, North Eastern Amhara, Ethiopia on July 2018. Levels of SR were 60, 80 and 100 kg/h and that of NL were 50, 100 and 150 kg/ha in the form of Urea (46% N). The experiment was conducted in a 3x3 factorial arrangement of treatments in a Randomized Complete Block Design (RCBD) with 3 replications giving a total of 27 plots, each measuring 2×1.4 m2 . Chemical composition for forage quality measurements were analyzed. Results showed that the interaction between seed rate and nitrogen rate had a significant (p<0.05) effect on almost all quality parameters measured. Increasing trend for crude protein content with increasing levels of seed rate and level of nitrogen were recorded, with the crude protein content ranging 7.4 to 8.6%. The NDF, ADF and cellulose contents ranged 51-58, 30-33 and 26-29%, respectively, and tended to increase with increasing seed rate and nitrogen rate of fertilization. Thus, high seed rate and nitrogen rate leads to improved forage quality. Generally, combination of 100 kg/ha seed rate and 150 kg/ha nitrogen recorded higher forage yield with higher quality and higher net return and benefit cost ratio (2.56) over rest of the combinations. Thus, seed rate of 100 kg/ha and nitrogen fertilizer rate of 150 kg/ha Urea can be recommended for better nutritional quality use by farmers in Sirinka area and other areas having similar agro-ecologies and soil type.

Aim of study: The introduction of new varieties and its adaptation is one of the breeding programs.The aim of this study was to compare 50 qualitative and 8 quantitative traits of Russian grape cultivars at Grape Vineyard.

Area of study: Research Station grade1 Takestan, Qazvin, Iran

Material and method: Evaluation of 50 quality traits of grapes was done in 2014, 2015 and 2018 Study qualitative traits of the grape are in the growth stages of the grape tree, which are: bud, young shoot, young leaf, current year shoot, flower, full leaf, fruit and woody branch.Whole leaf with 16 traits and fruit with 14 traits had the highest traits and bud with 2 traits had the least traits.

Results: In the study of quantitative traits, spike(n) traits, yield, maturity fruit, soluble solids (Tss), acidity (Ph), total acid (Ta), seed(n) and seed(w) were measured. Analysis of variance showed that the effect of cultivar on all traits was slightly significant. Anapiski Ramphi and Epozoski Ramphi had the highest yield (34370 and 30980 kg / tod,).

Research highlights: Due to the fact that the performance attribute is indexed compared to other attributes, the Epozoski Ramphi cultivar, which has the highest value compared to other cultivars, is selected
