Ever increasing demand for food and fodder due to growing population and livestock necessitates the urgency to improve productivity of the fodder crops. In this context, the concept of vegetative propagation technologies serves as an important tool for higher productivity. Conventionally, crops such as sugarcane, cassava, bajra napier hybrid grass and napier grass were cultivated by stem cuttings. This depends heavily on the quality of planting material and their availability. It is a huge barrier for the cultivation of fodder grass as the quality of planting material influences the sprouting, establishment, growth, tillering and fodder yield of grasses and also the higher requirement of planting material increases the overall cost of cultivation. Therefore, a more robust approach needs to be developed to address these limitations. Normally propagation by vegetative means assumes importance when desirable biotypes need to be multiplied in a short span of time. Also a suitable method of planting and number of buds reduce the cost of cultivation as well as transportation. Similarly one and two budded setts are ideal for optimum germination compared to larger seed pieces. Horizontal planting of stem cuttings is the most practical approach which increased sprouting and yield. Based on this ideology this paper reviews the various aspects of influence of planting methods and number of buds by vegetative propagated sett on sprouting, growth and productivity of fodder grasses.
