Abstract

Coppicing experiment was conducted in different sizes of diameter classe. 0-2 cm, 2.1 cm to 4 cm and 4.1 cm to 6 cm in Eucalyptur terelicarnis in ten year old plantation The average number of coppice shoot thrown by the stump of all the diameter classes was nearly equal. The height and diameter of coppice shoot was significantly higher In the stumps of larger diameter. The results will therefore have a far reaching effect on the management and exploitation of coppice regeneration and rotation of Eucalyptus teretlcornis plantalion in various parts of the State.

Abstract

Effect of GA₃ Urea, Superphosphate and Rallis tracel on the growth of teak seedlings in nursery and its cODsequent effect after planting the stumps of seedlings in the field was studied. The effect of GA in the nursery bed is positive and enhances the height growth, ischolar_main growth and vigor of the plan Is if applied alonwith the nutrients, the enhanced growth and vigor of treated sfedlings does not manifest itself in the performance of the stumps, prepared from the treated seedlings for planting in the field. The effect of GA₃, is temporary, and the enhanced growth and vigor of seedlings is suspended with the discontinu.tion of treatment. The performance of the stumps in the field conditions exhibit. Inferior quality and growth as compared to the untreated seedlings.

Abstract

The problem of poor seed setting in teak seed orchard at Mohghata Bhandara Forest Project Division (Maharashtra) was reported by the Managing Director, Forest Develepment Corporation of Maharashtra and Consenator, of Forests, Research and Education,Maharashtra Major insert pests which cause direct or indirect loss to the production of teak seed are, fruit borer and inflorescence feeder Pagyda salvalis, sap sucking bug, Leptocentrus vicarius and fruit borer, Dichocrocis punctiferills Defoliator, Hyblaea puera and skeletonizer, Eutectona machaerlis were noticed feeding on inflorescence in the absence of leaves, during present investigations. In the year 1980 various insecticides tested to control the insect pests were, dimeceron 0.05% nuvacron 0.05%; anthio 0.03%. endosulfan 0.25%, fenitrothion 0.25% and sevin 025%. along with hormonr alpha nophthyl acetic acid (planofix) 20 ppm. In the year 1981, only 2 insecticides i.e. nuvacron and endosulfan, which proved better in 1980 were sprayed. Different dosayes of nvacron i.e. 0.025% and 0.125% and endosulfan 0.125% and 0.0625% were tried so as to optimise the disc of application. Alpha nephthyl acetic acid (planofix) 40 Ppm was sprayrd alongwith the higher dose of the insecticides. The studies revealed that the best results as regards production and protection of inflorescence and fruits, can be obtaioned by spraying nuvacron 36 E (0.025%) and eodosolfan 35 EC (0.125%) water emulsion together with harmone, alpha nephthyl acetic ocid (NAA) 40 ppm.
