Ten sugarcane varieties of early and late maturing types were assessed for post harvest losses (0-120 h) and reduction in cane weight from February through June. The results revealed that the fibrous varieties of late maturing group such as CoSe 92423, CoS 97261 and CoS 8432 showed less reduction in cane weight and higher reduction in pol % whereas the less fibrous type of early maturing group like CoS 95255, CoS 96268 and CoS 8436 showed less reduction in pol % and higher loss in cane weight.

Aims: Cultivation of oyster mushrooms has increased vastly in a global scale during last few decades. Contaminants and indigenous microflora present in the substrate may led to the low productivity of mushrooms. Keeping this in mind, the present study was under-taken with slight modification in substrate preparation technique to eliminate dust particles from the substrate and to assure contamination free mushroom production. Study Design: Comparative evaluation between modified approach and control beds. Place and Duration: The study was carried out in Shri Laxman Prasad Pyare Lal Agro Products, Ayodhya during 2017. Methodology: The wheat straw substrate was immersed in the drum containing tap water, mixing properly and allowed to stand for 10-15 min to settle down the dust particle in the bottom of the drum. After that, the floating substrate was transferred to the slant surface so that the extra water was decanted off. This substrate was put in to the steam sterilised gunny bag and steeped in the chemical solution consisting of Formaldehyde (500 ppm) and Bovistin (75 ppm) for 18 h. For the Short Communication

Physical and chemical methods were assessed to minimize the sugar losses in stale canes of three sugarcane varieties namely CoSe 92423, CoS 8436 and CoS 8432. In physical method, five treatments were included, viz., cane stored under shade, water spray, canes with trash cover and cane with trash cover + water spray. Each treatment showed their effectiveness in minimizing sugar and cane weight losses in stale sugarcane being more in covering the harvested cane with the trash + water spray. In chemical method, five chemicals namely Mercuric Chloride, Salicylic Acid, Ammonium Bifluoride, Zinc Sulphate and Sodium Azide were sprayed (1% conc.) on harvested canes. Among these chemicals, Sodium Azide was found relatively more effective in minimizing sugar losses in stale sugarcane compared to other treatments.
