“…The Korean monsoon season lasts 20 to 30 days in general. Forage sorghum-sudangrass hybrid is harvested multiple times, therefore, the lodged sorghum-sudangrass hybrid can be harvested, and later re-growing forage recovers the whole season production [ 10 , 34 ]. Thus, even if the damage is caused by heavy rainfall accompanied by typhoon, it will be difficult to separate the damage from the impact on total forage production.…”

“…SSH can be successfully grown with winter forage crops, such as Italian ryegrass (Lolium multiflorum Lam. ), forage barley (Hordeum vulgare L.) and rye (Secale cereale) in double cropping systems (Ji et al, 2010). The sorghum × sudangrass hybrid [Sorghum bicolor (L.) Moench] (SSH) is widely cultivated as forage during the summer season all over the world.…”

A pot experiment was conducted at Experimental area, Agronomy Department PMAS- University of Arid Agriculture Rawalpindi to see the effect of different levels of nitrogen fertilizer on the growth and physiological traits of Sorghum Sudan Grass during March, 2022. Completely randomized designed was applied along with three replications. Seeds of Sorghum Sudan grass were collected from NARC Islamabad. Nitrogen fertilizer was applied in pots on 30th March, 2022, according to the treatments. Nitrogen played a significant role in the growth and physiology of Sorghum Sudan Grass. Nitrogen @ 150 kgha-1 is the best among other four treatments and attained the highest plant heights in three times (21.355, 65. 153 and 100.620 cm) respectively. However, results of nitrogen @ 200kgha-1 are approximately statistically at par with NPK. Nitrogen @ 150 kgha-1 gained the highest position in two times data (0.7050 and 1.4250) respectively. Nitrogen @ 200 kgha-1 gained less value than nitrogen @150kgha-1 might be excessive dose. Nitrogen nutrition played a key role in the enhancement of leaf area values; however nitrogen @150kgha-1nutrition had the top position (1.140 and 1.950) during two times respectively. Leaf area index data had statistically significant results but among the nutrition treatments nitrogen @150kgha-1nutrition is the best option attaining the highest values (91.475 and 152.550) respectively in two times. Nitrogen fertilizer at different levels had statistically significant effect on crop growth rate of sorghum plants; however nitrogen @150kgha-1nutrition treatment attained the highest value (0.5333) which was statically at par @200kgha-1nutrition treatment. Nitrogen @150kgha-1nutrition treatment had the top position (4061.9) but other three doses of nitrogen values having minute difference with nitrogen @150kgha-1 and higher than control. Four doses of nitrogen fertilizer produced more net assimilation rates than control and nitrogen @150kgha-1gained the highest value (45.653) which was statistically at par with nitrogen @200kgha-1(43.521).Nitrogen fertilizer is an inorganic fertilizer provides the nutrition the plant fastly and provides better performance at nitrogen @150kgha-1. Nitrogen @200kgha-1 showed better performance than control but less than nitrogen @150kgha-1, therefore this finding improves the economics of the study.

This study was performed to investigate the effects of harvest stage of sorghum × sorghum hybrid (SSH) on nutritive values and quality of round baled SSH silage manufactured with SSH grown in paddy land of Department of Animal Resources Development, National Institute of Animal Science, RDA. SSH "SS405" was harvested at two different growth stages (heading and ripen stage) and ensiled at each harvest stages. Crude protein content of round baled SSH silage increased with delayed harvest maturity, but contents of ADF (acid detergent fiber), NDF (neutral detergent fiber), TDN (total digestible nutrient) and in vitro dry matter digestibility (IVDMD) was not changed. The pH in round baled SSH silage ranged from 3.8 to 4.4 at two different harvest stages, and pH in heading stage was higher than that of ripen stage. The content of lactic acid of round baled SSH silage increased with delayed harvest maturity (P<0.05), but the content of acetic acid decreased (P<0.05). The contents of lactic acid and acetic acid in ripen stage were not influenced by manufacture method of silage. The content of acetic acid in round baled SSH silage of heading stage increased as compared to that of trench SSH silage (P<0.05). Therefore, this study suggest that round baled SSH silage manufactured in both heading and ripen stage can improve the silage fermentation.
