Sugarcane bud chips: A promising seed material

Abstract

Sugarcane is normally propagated by stalk cuttings consisting of 2 to 3 bud sett. In conventional system, about 6 -8 tons seed cane /ha is used as planting material. Establishing the sugarcane crop using bud chips in place of setts could save about 80% by weight of the stalk material, however this technology has not been scaled up at commercial levels due to poor survival of bud chips under field conditions. Present study is aimed at improving sprouting and establishment of bud chip seed stocks of sugarcane by pre-planting soaking in growth promoting chemicals. Treated bud chips recorded higher bud sprouting, root number, fresh weight of shoot and roots and plant vigor index. Studies have shown that bud chip could be one of the most viable and economical planting material in reducing the cost of sugarcane production.

Early-Arbuscular Mycorrhizal Fungi-Application Improved Physiological Performances of Sugarcane Seedling and Further Growth in the Dry Land

“…The system of seedling transplantation shortens the age of plants in the field by one month compared with that of a conventional system so that late harvest can be avoided (Jain et al, 2010). The role of mycorrhiza in increasing the sugarcane yield is by increasing the number of shoots per clump, stem height and stem diameter, and improving the soil pH (pH 6.4-6.9) (Fundora et al, 2008).…”

Influence of Planting Methods, Age of the Seedlings and Nutrient Management on Yield and Quality of Sugarcane raised from Bud Chip Seedlings in Sandy Loam Soils of Andhra Pradesh

“…In year 1977, Andhra Sugars has fabricated bud chip machine and Ramaiah et al demonstrated bud chip technology using three varieties, Co 419, Co 975 and Co 997. Further, several other workers had established that about 80% seed material can be saved by bud chip seed material [1,2]. Scientist working at NPKRR Cooperative sugar Mills reported that bud chip seedlings transplanting technique as most suitable technology for Cauvery delta areas.…”

Mini-toletes de cana-de-açúcar: gemas, biorreguladores, adubação nitrogenada e déficit hídrico

“…Segundo Jain et al (2010), a utilização de fragmentos do colmo contendo gemas isoladas apresentam baixos índices de brotação e redução na altura inicial das plantas. Além disso, devido às limitações em relação às reservas energéticas dos fragmentos de tolete, ocorre baixa sobrevivência das gemas em condições de campo.…”

“…Além disso, essa grande massa de material para o plantio acarreta problemas de transporte e armazenamento, causando a rápida deterioração dos colmos, o que reduz a viabilidade das gemas e posteriormente a emergência (JAIN et al, 2010).…”

“…Esta prática, entretanto, possui limitações, dentre elas, o fato de as reservas nutricionais dos mini-toletes serem limitadas. O teor de nutrientes decai rapidamente durante a emergência, juntamente com a umidade, levando a baixa taxa de sobrevivência do material vegetal em campo (JAIN et al, 2010). Em mini-toletes contendo maiores quantidades de reservas, a brotação ocorre mais rapidamente e é mais vigorosa (SIMÕES NETO, 1986).…”
