Pellet Durability Index (PDI), pellet hardness, bulk density of pellets and feedstuff, unit density of pellets, and power consumption were measured and evaluated. Results revealed that the interaction of longer die lengths, higher moisture content, and smaller particle size treatment (L3M3P1) significantly increased the PDI (95.6%), hardness (6.4 Kg), and bulk density (683.97 Kg m-3) when it compared with other treatments. Unit density increased with the treatment (L3M2P2) when it compared with other treatments which it was 1453.29 Kg m3. The highest power consumption of 4.51 Kwh-1 was recorded with the treatment (L3M3P3) while the lowest value was for the treatment (L1M1P1) and it was 3.07 Kwh-1 but statistically, there were no significant differences in power consumption between the treatments, the differences were only mathematically. According to the results obtained in this work, we can conclude that when using the long die path combined with high moisture content and fine feedstuff can produce better pellets which are physically and mechanically accepted by farmers.","PeriodicalId":239337,"journal":{"name":"Kirkuk University Journal For Agricultural Sciences","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135247203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this research was to examine the consequence of cutting dates on the yield of forage and seeds, as well as on the components of various Vicia varieties. The experiment was designed as a factorial design and conducted using a randomized complete block design. The least significant difference (L.S.D.) test with a significance level of 5% was used for the statistical analysis. The three Vicia varieties tested were common vetch (Vicia sativa), narbon vetch (Vicia narbonensis), and bitter vetch (Vicia ervilia). Two cutting dates were used, namely, control (Co, no cut), cut 1 (80 days after sowing), and cut 2 (20 days after the first cut). The findings of this research demonstrated that the interaction between common vetch and cutting at 80 days after sowing produced the highest values of the dry matter percentage trait. Meanwhile, the interaction between narbon vetch and cutting 20 days following the initial cut produced the maximum fresh yield (ton/ha) and stem dry weight (g) values. The highest recorded values for the characteristics \"pod count per plant\" and \"seed yield (kg/ha)\" were obtained through the interaction between the control treatment and narbon vetch. However, the interaction between cutting at 80 days after sowing and narbon vetch produced the highest values of the 100-seed weight trait (gm). The variation in climatic conditions between seasons may explain these results.","PeriodicalId":239337,"journal":{"name":"Kirkuk University Journal For Agricultural Sciences","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135247379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Arid and semi-arid ecosystems are likely to be particularly affected by changes in wind speed and vapour pressure regimes, changes in those regimes may show from climate data that vapour pressure has clearly increased during these years. For instance, in January and February of 2017 wind speed reached 8 and 9 (m. sec.-1). Sulaymaniyah Meteorology Department reported a lesser speed of 0.1 (m. sec.-1) in the months 4, 5, 6 and 9, on average the greatest rates of 3.1 and 2.2 (m. sec.-1) in 1985 and 1992. on the other hand, in 1991 recorded the lowest rate of (1 m. sec.-1) amounts and times of precipitation during the study years, floods occurred in some seasons the dry seasons less than 300 (ml) were very few, while the remaining seasons were more than 450 (ml) rainfall amounts in the seasons 2006-2007, 2007-2008 and 2008-2009 were among the driest seasons during the years of the study Which was straight (66000, 87000, 86000) dunam. as the agricultural areas were reduced to their lowest levels, although the levels of precipitation were acceptable.
