Abstract

Agroforestry systems of the hilly regions of the north east are small scale, primitive land use systems, evolving through traditional knowledge requiring very little inputs in terms of irrigation, fertilizers and pesticides. The different components of the agroforestry systems were analyzed for their natural enemy complex through a monthly sampling programme. Maintenance and potential role of natural enemies’ complex in various compartments of such systems are discussed in the light of land use practices and holding size.

  • In Mizoram the practice of shifting cultivation termed as “jhum” or “slash and burn” is still the predominant form of agriculture

Summary

Introduction

In Mizoram the practice of shifting cultivation termed as “jhum” or “slash and burn” is still the predominant form of agriculture. In Mizoram traditional forms of agroforestry have been practiced by some farmers in their own way. It was first innovated by Jha and Lalnunmawia (2000, 2003) and named them as Tree-Greenhedge-Crop farming system and Bamboo based agroforestry system respectively. The various multipurpose tree species and predominant agroforestry systems prevalent in Mizoram have been reported by Lalramnghinglova and Jha (1996). Traditional systems having Tectona grandis (Verbenaceae) and crops like Zea mays (Poaceae) and Oryza sativa (Poaceae) are the most common and successful agroforestry practices, during the seedling, sapling/pole stages of growth of the tree component. The present investigation focuses on comparing the distribution of natural enemy complex in teak, tung and subabul based agroforestry system of Aizawl
