Скачать или смотреть Perennial Forage Sorghum: An Economical Forage for Dairy Producers by Dr. P. C. Patel

Sorghum has the ability to provide good dry matter productivity even in semi-arid tropics regions. Being an annual crop, it fits well in the cropping system and can be grazed, cut fresh, made into hay, or ensiled. Its quick-growing habit, high forage yield ability, high dry matter content, leafiness, wider adaptability, and drought tolerance really make it an ideal forage crop.

Perennial Forage Sorghum: An Economical Forage for Dairy Producers
Due to rapid urbanization and industrialization pressure on agricultural land is increasing exponentially to fulfill the growing population's food demands. The crop production system is shifting towards the use of multipurpose crops for agricultural sustainability which are having low water requirements and high yield potential per unit of water. There is an urgent need for the development of location-specific production technology to offer an excellent opportunity to provide nutritious forage for livestock. The introduction of perennial multi-cut will also reduce the cost of cultivation.
Forage Sorghum:
Sorghum, sudangrass, and sorghum-sudan grass hybrids are very versatile and have an important use as forages. The quick-growing nature, high green and dry fodder, leafiness, drought tolerance, and wide adaptability make it an ideal fodder. Sorghum fodder is in great demand due to its good protein concentration and its high digestibility. Various forage sorghum varieties/hybrids of single-cut, dual-purpose, and multi-cut types are available which have great demand among farmers and can be used as silage, hay, green chop, and pasture also.
RECOMMENDATION
The results indicated that for growing forage sorghum variety SSG.59-3 in monsoon (Kharif) in soils having medium availability of P and deficient level of S, farmers are advised to apply 40 kg P (87 kg DAP) and 20 kg S (133 kg gypsum) per ha every year to obtain maximum forage yield, total returns, net ICBR and better quality (CP and DDM production) of forage (Fig 6). (A common basal dose of 25 kg N/ha at the time of sowing, 25 kg N/ha at 30 DAS, and 25 kg N/ha after the first cut i.e., 60 DAS should be applied).

Prussic acid (HCN) poisoning:
If conditions are unfavorable, plants can be analyzed at a certified lab – if HCN is greater than 500 ppm (DM basis) then the plants should not be grazed or fed. Animals have this ability to break down prussic acid as long as there is enough reserve of Sulphur in their body tissues; however, if depleted, sulfur deficiency causes a reduction in appetite which in turn leads to a decline in average daily weight gains or milk production.
