Abstract

The first study in Iraq was carried out on the Panicum plant in Diyala Agriculture Directorate for the season 2017-2018 in order to identify some of the physical and chemical traits and yield of feed . The study included two experiments, First experiment, The seed germination rate was measured during the months of January to May as well as the age of seedlings, The seeds were planted on two dates: the first on March 22, 2018 and the second on March 31, 2018, and the seedlings were obtained from age 28 and 19 days to study their effect when transferred to the field. The second experiment (field experiment), the soil service operations were carried out by plowing, smoothing, adjustment and installing drip irrigation system. Seedlings were planted at a distance of 0.5 m between line and another and 0.5 m between plant and another. The measurements were taken for the studied traits after 60 days of planting. The results of the first experiment showed an increase in seed germination from January to April, with 67%, 98% and 95% respectively, while in May the percentage reduction to 95% and the seedlings transferred to the permanent field at the age of 28 days significantly exceeded all studied traits of the leaf length, root length, leaves number, wet weight of the total vegetative and dry weight of the total root. The results of the second experiment showed the superiority of the seedlings at the age of 28 days in the traits of plant height, number of leaves per plant and total dry matter per hectare, while the seedlings exceeded the age of 19 days in the traits of green fodder per hectare and total chlorophyll.
