Field experiments were conducted to evolve a suitable management strategy against Tomato leaf curl virus (ToLCV) disease and its whitefly vector, Bemisia tabaci. White nylon net as a physical barrier against whitefly in the nursery bed as well as two neem based formulations viz., Neembicidine and Bioneem as biopesticides were used in the main field, reduced ToLCV incidence, whitefly population and increased yield. The seedlings raised in the nursery bed covered with nylon net showed no ToLCV incidence, whereas, 8.0 percent incidence was recorded in the uncovered nursery bed. The best treatment was found where seedlings raised under nylon net cover in the nursery bed along with spraying of Neembicidine @ 2.0 per cent at 20 and 35 days after transplanting (DAT) showed no ToLCV disease incidence (0.00%) with highest yield (322.22 q/ha) followed by the treatment where seedlings were raised under covered condition as well as spraying of Bioneem @ 2.0 per cent at 20 and 35 DAT showed a low disease incidence of 5.33 per cent with 318.89 q/ha yield. Whereas seedlings raised under covered condition along with recommended conventional insecticide, Dimethoate @ 0.2% at 20 and 35 DAT showed disease incidence of 13.33 per cent with lower yield of 285.19 q/ha. The highest disease incidence was recorded in the untreated control plot as 89.33 per cent corresponding with lowest yield of 98.89q/ha.

Demand for coke is on the rise and is predicted to go up further in the years to come. As on today, among the various commercially established coke making technologies, non-recovery/heat recovery ovens are established to be the sustainable ones. It has been investigated that the north eastern region (NER) of India has a number of coke ovens which are non recovery types and without heat recovery systems. Huge volume of coke oven gases released from these ovens which have high calorific values and contribute to major environmental degradation. In this paper, an attempt has been made for maximum utilization of these coke oven gases (COG) for heat recovery. The modern heat recovery ovens which are environmentally sustainable and have ease in operation have minimized the stringent environmental issues. This non-recovery/heat recovery coke making technology developed for high sulphur, high volatile coals of NER India for caking coals will be a promising technology for future, particularly in developing countries that are facing power and coke shortages.Keywords
