Tempo of Teak plantations has picked up since the National Commission on Agriculture suggested in 1972 with the object of generating resources for the plantations programme as a commercial activity. Forest corporations were established and as a result financial viability of the plantation programmes, gained importance. With the rising prices of quality teak timber, private entrepreneurs have also embarked on teak plantation on lucrative terms which in turn has lead to controversy on speculations/ returns projected by some of them. Therefore, a case study is described in detail.- Sewage Water as Potential for the Tree Growth -a Study on Teak, (Tectona grandis) Plantation

Discharge of Sewage Water (SW) is primary source of pollution especially near big cities. But their irrigational and manural potential can he harnessed for production of arboreal biomass. In Maharashtra and adjoining states a large number of farmers are going for irrigated teak (Tectona grandis) plantations. Use of SW in this context will not only decrease cost of plantation by saving expenditure on manuring, but will reduce the pollution as well. In a case study of teak plan actions irrigated with SW, it was observed that growth in terms ofh eight and girth were significantly higher (P- Growth Responses to Irrigation : Eksal (Ambhadi) Teak Plantation - a Case Study

A critical assessment of series of high input teak plantations established by Divisional Manager, F.D.C.M. Ltd., Thane Division has been carried out. Application ofirrigation and fertilizers have definitely shown positive response and has resulted in gains overrainfed plantations. Continuous monitoring of response to irrigation has revealed that except during juvenile stage, there is lack of response to irrigation during winter months i.e. period of dormancy. Claims of spectacular growth with higher inputs round the year made by number of agencies engaged in tree plantation ventures, are thus not supported. A judicious application of irrigation and greater emphasili on genetic improvement is thus stressed.- On Exponentially Ternary 2-Free Integers

Let n be any natural number. For n>1 , let its prime power factorization be n=πp1α1. If the digit 2 does not appear in the ternary expansion (i.e. in the representation in the base 3) of α1 for every i, then n is called an Exponentially Ternary 2-Free (ETF2) number. By convention we regard 1 as an ETF2 number. Let E be the class of all ETF2 numbers. If we denote by E(x), the number of (positive) integers ≤x contained in E, then it is implicit in some results of Murty [3] thatE(x)=Ax+O(x1/2).
