| dc.description.abstract | The experiment was conducted to evaluate the effect of fertilizer level and harvesting age on morphological characteristics, dry matter yield and chemical composition of Sudan Grass (sourghum Sudanese) grown under irrigation condition at Soroka farmer training center (FTC), in northern Amhara Region, Ethiopia. A factorial arrangement in a random complete block design (RCBD) with four level of fertilizer (0, 50, 75 and 100kg/ha) and three harvesting ages (30, 50 and 70) with 3 replications in 3m×3m (9 m 2 ) plot size area were used. Data on morphological characteristics, dry matter yield and chemical composition of the grass were recorded. In addition, harvesting age significantly affected the morphological characteristics and DMY of Sudan grass except number of leaves per plant (NLPP). Plant height (PH), dry matter yield (DMY), leaf length (LL), number of root per plant (NRPP), root length (RL), and dry matter yield (DMY) which were increased with increasing harvesting age, while number of tillers per plant (NTPP) and leaf to stem ratio (LSR) were showed a decreasing trend. The CP content declined as the harvesting age increased, while NDF, ADF and ADL content increased. The highest ash content (13.48%) was recorded at middle (50) harvesting age. The Level of fertilizer application significantly affected plant height (PH), tillers per plant (NTPP), and number of leaf per plant (NLPP) but no other agronomic parameters of Sudan grass (cultivar Michello). Application of Fertilizer levels and harvesting ages had an interaction effect was significant on all chemical composition parameters, but not for on crud protein yield. The lowest NDF (67.87%) and the highest ash (13.38%) content were recorded from 50 kg fertilizer per hectare. From the result of the present study, it is concluded that Sudan grass can be harvested at 50 days of age and use 50 kg/ha level of fertilizer for good quality forage, higher dry matter and crude protein yield with minimum fertilizer cost. At last, to fully utilize the potential of Sudan grass, further studies on agronomic performances, and chemicals composition, under various agroecology and animal feeding trial evaluations are recommended. | en_US |
