Abstract

Tamil Nadu Afforestation Project (TAP) was carried out from 1997 onwards to restore the degraded forests, by involving the local villagers abutting such forest areas, based on Joint Forest Management (JFM) concept. The project mainly focuses on improving the forest, hydrological resources and community development. Monitoring the project is vital to assess the long-term sustainability of the resources and thereby to make informed decisions. Among the many criteria and indicators of the project objectives, forest cover improvement would attract the attention of the policy makers. Information about the change is necessary for monitoring the progress of intervention carried out in any project. The paper deals with the forest cover change detection using remotely sensed data obtained before (1998) and after (2002) the intervention of TAP, in Jothinagar village of Tiruvannamalai District in Tamil Nadu State. The results shows that there is an improvement in 35% forest cover in the study area over a period of four years.

Abstract

Small cardamom (Elettaria cardamomum Maton), ... the Queen of Spices is au important spice crop cultivated on a large scale in the Western ghats of South India. Rhizome rot is a major disease caused by Rhizoctonia solani Kuhn in cardamom plantations. The disease occurs in a severe form during monsoon and results in heavy crop losses. In the present study, exotic and native isolates of Trichoderma viride Pers. Fr. and T.harzianum Rifai were tested against the pathogen under in vitro conditions. These isolates were further evaluated in disease-prone areas in the field. Results showed that all the isolates tested showed antagonistic activity through hyphal coiling, penetration and lysis of the hyphae of the pathogen besides inducing growth inhibition of the laller. Among the nine isolates tested in the field, eight were found effective in controlling the disease incidence. An exotic isolate of T. harzianum and a native isolate of T. viride were found to be most effective, the reduction in disease incidence being upto 52 to 69 per cent.

Abstract

Adequate symptoms assessment is essential in premenstrual syndrome prevention. Assessment scales were designed to support practitioners in identifying adolescents at premenstrual syndrome risk. The Premenstrual syndrome scale is one of the most extensively studied symptoms assessment instruments, although the majority of studies focused on validity rather than reliability.
