Low density plantings complemented by natural regeneration is an increasingly common reforestation technique to ensure growth of a sufficient number of trees from desired species while maintaining natural processes such as succession. One such form of low density planting that aims at lowering establishment costs—oak clusters—has been developed as an alternative to row planting since the 1980s ...

In a three year study, IOOderate and severe root pruning just before planting was compared to no root pruning, on two size classes of seedlings (smaller and larger than average). Seedlings were bar planted in holes the full depth of the planting bar blade. For the smaller seedlings, survival was 1.0 percentage point higher for moderate pruning and 5.6 points lower for severe pruning compared to...

A field trial was conducted at the research farm of RRL, Jorhat during 1995 and 1996 to study the performance of Mentha Piperita under varying dates of planting and row spacings, maximum herbage and oil yield were obtained from January plants crops. Yield deceased when planting was delayed planting at a closer row spacing of 45 cm recorded the maximum herbage yield of 61'92 q/a while the yield ...

Balancing forest harvesting and restoration is critical for forest ecosystem management. In this study, we used LANDIS, a spatially explicit forest landscape model, to evaluate the effects of 21 alternative forest management initiatives which were drafted for forests in the upstream region of the Hun River in northeastern China. These management initiatives included a wide range of planting and...

A numerical method called Multiple Attribute Decision Making (MADM) has been used for rational selection of a cotton harvester out of a finite number of cotton harvesters available the world over. In India, efforts are being made to design and develop a commercial cotton harvester to harvest selected cotton varieties sown by adopting common agronomic practices locally for cotton cultivation. Th...
