Abstract

Containerized/Polybag raised seedlings were ischolar_main pruned at 0, 5 and 10 cm length from collar regions before planting and given split nitrogen doses of 0, 40, 80 and 120 kg/ha. These conditioned seedlings were studied for morphological, physiological, nutritional status and survival per cent. Root pruning significantly reduced seedling growth and biomass production in monsoon as well as winter planting. Severely pruned (5 cm from collar region) seedlings showed lesser growth and biomass production than light pruned ones (10 cm from collar region) in both planting season. Application of nitrogen up to 80 kg N/ha increased plant growth biomass. Root pruning coupled with nitrogen application improved the morphological attributes and was observed more in light pruned seedlings than severely pruned ones when 80 kg N/ha was applied. Root pruning decreased xylem water potential and ischolar_main regeneration. Total soluble sugars, starch and carbohydrate content of the transplants increased with increase in severity of ischolar_main pruning in monsoon planting season, whereas, in winter planting, these reserves increased with increase in ischolar_main pruning length. Nutrient content and uptake were affected with ischolar_main pruning length. Nitrogen application increased NPK content and their uptake in the seedlings. Application of 80 kg N/ha in 10 cm pruned seedlings increased the NPK content and their uptake in the seedlings. Survival per cent increased with nitrogen application upto 80 kg/ha and decreased with increase in ischolar_main pruning severity. Light pruning (5 cm from collar region) with medium application of nitrogen improved the survival percent. In comparison to monsoon, winter transplanting had lower survival per cent in all the treatments.

Abstract

The study examined the various factors affecting cultivation of medicinal and aromatic plants (MAPs) in Rampur block of district Shimla in Himachal Pradesh by surveying of 213 farmers (61 female and 152 male) in January, 2010. The findings revealed that a total 10 factors were perceived by the farmers which pose hindrance in the cultivation of MAPs in the area. These factors were ranked as: Lack of awareness about medicinal and aromatic plants, lack of knowledge about cultivation practices, lack of marketing awareness, non availability of local market, subsidy culture, lack of training and visit programme, lack of demonstration of modern technologies, lack of value addition knowledge and facilities, no storage facilities, migration of people to urban areas for wages. Therefore it is recommended that the policies and programmes emphasis on these factors will gear up the cultivation of medicinal and aromatic plants in these areas.

Abstract

Progeny trial of Pinus roxburghii was conducted to evaluate the oleoresin yielding potential of half-sib progenies of chirpine. Trees of 60 progenies were enumerated and abstracted for diameter at breast height (d.b.h). The progenies having more than 30 cm d.b.h were selected for oleoresin tapping experiment. In total, 22 out of 60 progenies had minimum one tree above 30 cm d.b.h in at least two replications. Hence, these progenies were selected for stem oleoresin tapping. The maximum value of oleoresin yield was noted in Kopra-P5 (1527.5 g/season) and lowest oleoresin yield was found in Chretmansu-P4 (455.0 g/season). The highest percentage of turpentine content (25.05%) was found in Jubble Green Centre and lowest value of 18.19 per cent was obtained for Bagthan-PT- Black Base. Maximum percentage of rosin was observed in (80.06%) Bagthan-PT Black Base. The highest value of (80.25°C) melting point of rosin was noted in Kaldoo P10 and lowest melting point (68.25°C) was observed for Jubble Green Centre.
