Abstract

With a view to evolve cloning procedure for Bambusa multiplex, Bambusa tulda and Bambusa vulgaris single node culm cuttings were subjected to four different treatments for 24h viz., water, or 1, 2 and 4 mM NAA. The treated cuttings were horizontally placed and covered completely with sand in ground beds of low-cost mist chamber. After two months, the cuttings were scored for adventitious ischolar_maining percentage, ischolar_main number and length. Significant influence of graded concentrations of NAA on adventitious rhizogenesis was observed. In B. tulda and B. vulgaris the treatment of 4 mM NAA to culm cuttings proved superior for ischolar_main induction while 2mM was found best for ischolar_maining in B. multiplex.

Abstract

The paper gives an account ahout the status of Joint Forest Management (JFM) in the State of Nagaland. The land holding pattern in the State is totally different from the other States. In the State, most of the land belongs to people. The involvement of people has playerl an important role in protection and conservation of forests. Through JFM programme people are also getting involved in biodiversity conservation. The Samanvit Gram Vanikaran Smriddhi Yojna (SGVSY) and National Afforestation Programme (NAP) implemented by Forest Development Agencies (FDAs) have given momentum to JFM programme in the State which lead to increase in dense forest cover. The JFM programme is very successful in the State.

Abstract

In this article volume tables of Neem based on data collected by felling 25 sample trees from different plantations in Gandhinagar Division of Gujarat State are presented. Different models were tried. Equations having the best fit on the basis of minimum Furnival Index, minimum standard error of estimate and maximum correlation coefficient have been selected for volume calculations.

Abstract

Observations were made on 52 month old Teak plantation on a private company land at Bhavnagar planted along the western side of Eucalyptus tereticornis shelterbelt. The growth of Teak plants showed that the shelterbelt of E. tereticornis of average growth parameters of 20.6 m height 21.3 cm dbh and 28.1 cm collar diameter, affect the growth of Teak plants upto a distance of 180 m. Teak maintained the maximum average growth data of 9.2 m height, 10.2 cm dbh and 14.0 cm collar diameter in open area. The maximum reduction in growth parameters as observed in the first row of plants at 4.0 m from shelterbelt viz., 48.9% in height, 61.8% in dbh and 50.7% in collar diameter in comparison to the plants in open area. The concentration of per cent organic matter, available nitrogen, extractable cations viz., Ca, Cu, Zn, Mn, Fe, Co were significantly higher and K and Mg were slightly lower in plantation area than in agricultural field. However, the concentration of the cations were lowest near the shelterbelt (0.5 m) and highest at 4.0 m distance from the shelterbelt. Thus it showed that nutrient availability in general and light in particular accounted for the poor growth of Teak plants beneath the canopy of shelterbelt.

Abstract

In this article tables are based on the data collected from Acacia tortilis plantations at KJD Abadi planations of Khajuwala Range, Chattergarh Division of IGNP area. The tables are based on 40 fulled trees. Different models were tried. The equation having the best fit on the basis of minimum Furnival Index have been selected for volume calculations.
