Abstract:
A field experiment was conducted to study effect of trash burning, mulching and trash incorporation by trash shredder on growth, yield and quality of sugarcane during 2017-18 and 2018-19 at Agricultural Research Station, Perumallapalle, ANGRAU, Andhra Pradesh. The experiment consists of 4 treatments viz., control, burning of trash, mulching of trash and trash spreading by trash shredder. Recommended dose of fertilizers (224-112-112 kg N-P₂O_{5- 2}O ha^-1 for plant crop and 336-112-112 kg N-P₂O₅-K₂O ha^-1_, respectively for ratoon crop) were applied to all treatments. Data on tillers ha^-1‑, shoot population ha^-1 and number of millable canes (NMC) ha^-1 yield attributes viz., cane length and girth, juice quality parameters like sucrose, CCS and purity, cane yield, CCS yield were recorded in all treatments. Results revealed that significantly the highest cane yield (124 t ha^-1) was recorded with application of trash spreading by trash shredder followed by trash mulching (119 t ha^-1). Similar trend was followed in cane length also. Significant improvement in tillers, NMC was observed with application of trash by the trash shredder. Significantly the highest CCS yield (15.78 t ha^-1) was recorded with application of trash by trash shredder followed by trash mulching (15.18 t ha^-1).
