Abstract

Different parts of Arunachal Pradesh were surveyed to collect three genera Xylaria, Daldinia and Hypoxylon of the family Xylariaceae. A total of 10 species belonging to these genera were identified, which included eight species of Xylaria and one species each of Daldinia and Hypoxylon and are the first report from the state.

Abstract

The Forest Research Institute, Dehra Dun has prepared compost by using variety of organic matter by using the Berkeley method. The compost so prepared was analyzed and the results of the analysis have shown that all the composts prepared have nutrients in substantially higher quantities and they are considerably better than Farmyard Manure and the compost being generally prepared.

Abstract

It is clear from the above discussion that such a large venture should be planned with bottom-top approach with local perception and well in advance for harnessing full benefits and better results, transparency and accountability. Such massive plantation drive helps in enriching the environment by conserving natural resources and provide livelihood security to the poor in the region in the form of greater employment opportunities during lean period and future supply of tree products.

Abstract

The paper presents the results of the investigations carried out for determining of best combination of method of seeds sowing and optimum irrigation schedule for the production of maximum healthy seedlings of Quercus leucotrichophora (Syn. Q. incana). The results of the experiment indicate that irrigation twice a day (morning and evening) and dibbling or line sowing method take significantly lesser time for germination of seeds and results in higher germination and plant per cent and healthy growth rate of seedlings of this species. Dibbling method of sowing and irrigation twice a day proved to be the best combination.

Abstract

The article deals with the findings of a field experiment conducted in sodic soil (Natrustalf) of Kurukshetra Forest Division, Haryana, with the objective to determine the most suitable season for planting tree species in such problem soils. The study brought out that pre-monsoon is the most favourable season followed by post-monsoon season for planting tree species in such problem soils. Planting during monsoon, a normal silvicultural practice, was not suitable for these soils. Among the species tried, Tamarix articulata was most promising, but E. tereticornis and C. citrinus also performed satisfactorily.

Abstract

A field experiment replicated four times in randomised block design on highly eroded slopy Sandy loam soil, was conducted to see the effects of two levels each of nitrogen (control and 60 kg N/ha) and phosphorus (control of 20 kg P₂O₅/ha) and mulch application (control, pine needles and local shrubs) on the mortality and growth of Pinus roxburghii transplantation. Observation recorded after 21 months revealed that application of mulches in general, and local shrubs in particular, resulted in higher height and lower mortality of plants. Effectiveness of nitrogen and phosphorus for boosting up the plant growth and retarding its mortality enhanced through their application with mulch.

Abstract

Growth and yield of wheat crop as influenced by single row bund plantation of Populus deltoides 'G-3' grown on southern aspect of the field in east-west direction were investigated. Results show that wheat grain yield improves in the vicinity of trees. The other crop parameters have shown no significant difference between different distance treatments. The total income from 21 trees works out to be Rs. 8.70000 at 6 years of age. An increase of about 10.63 kg in wheat grain yield in a zone of 15 m from tree line was found.

Abstract

Effect of different plant cavers on pbysico-chemical properties of soil was evaluated in Doon Valley environmental conditions. Amount of organic carbon, total nitrogen, available phosphorus and potash, exchangeable magnesium and cation exchange capacity was highest in soils under Eucalyptus hybrid plantations, and lowest in soils under agriculture landuse except the lowest values of available phospborus and potash in soils under Chir (Pinus roxburghii). Available nitrogen in agricultural soils and exchangeable calcium in soils under Teak (Teeona grandis) were highest in amount while these nutrients were lowest in soils under Sal (Shorea robusla) and agriculture, respectively. Other species exhibited different patterns of soil characteristics. The highest C:N ratio in soil. Under Subabul and lowest in soils under Chir iniicated bigbest production of decomposable leaf litter is oils under Subabul and lowest in soils under Chir. The surface soil (0-10 cm deep) contained bighest amount of mineral nutrients. Seasonally, mineralization of nutrients was found to be highest in the month of February and lowest in June.
