Abstract
"The investigation entitled ""Studies on storage of turmeric seed rhizomes"" was carried out to find out suitable method of storage and to reduce the storage losses due to diseases and insect pests at Kittur Rani Channamma College of Horticulture, Arabhavi, University of Agricultural Sciences, Dharwad during the year 2000 and 2001. The influence of different storage methods, viz., storage in pits lined with sand, sugarcane trash, wheat straw, dry turmeric leaves, storage in ZECC, polyethylene bag with 0.5 per cent vents, gunny bag and heap method and also the effect of pre-treatment of rhizomes with chemicals, viz., Carbendazim, Captan, Mancozeb, Contaf, Monocrotophos, single or in combination and biological antagonist, viz., Trickoderma harzianum on the storage losses, recovery of healthy rhizomes and germination percentage in the field were studied. Among the different methods, storing in ZECC was found to be the best method with least per cent PLW (12.31%), sprouting (18.61%), rotting (1.91%) and insect damage (0.00%) and maximum recovery of healthy rhizomes (95.86%) at the end of storage period (90 days) and highest percentage of germination (99.38%) in the field, followed by storing in polyethylene bag with 0.5 per cent vents and pits lined with wheat straw. The recovery of healthy rhizomes and per cent germination in the field were 90.39 per cent and 96.09 per cent in polyethylene bag and 89.89 per cent and 87.31 per cent in pits lined with wheat straw as compared to 57.73 per cent, 46.92 per cent in control (Heap method), respectively. The pretreatment of rhizomes with Captan (0.3%) or Mancozeb (0.3%) along with Monocrotophos (0.1%) were found to be effective in minimising the storage diseases (3.20-3.65%) and insect pests (5.30- 7.15%) as compared to untreated control (14.75% and 34.60%, respectively)."
