Abstract

In search of promising clones suited to tbe Tarai climate a trial of sixty clones imported from five countries was laid in replicated randomised block design. Propagation medium was ETP. D-75, S7C20, S7C8 066, S7C15, S7CI 2502 and 69/5 turned to be the best suited ones. Most of these are American clones. Overall performance of Italian, Australian, Dutch and German clones were inferior. Rotation age of above promising clones should be reduced to 6-8 years if grown for pulp and intercropping.

Abstract

With the intention of throwing new clones of Poplars to production population in Terai region Nursery-testing of approximately three hundred exotic and indigenous clones has been done. After screening selected clones have been put on trial for field evaluation. Promising Populus deltoides clones among exotics are S7C4, S7C2, 113324, 3324, and 82-33-3 while indigenous one' are L-12, L-13, L-30, L-34 and L-52. These clones are to be now planted on large scale in monoclonal mosaic block design.

Abstract

In U. P., Tree Improvement Programme is being undertaken in the three regions of Silviculture i.e. Hills, Sal and Southern Region. This paper includes the improvement programme of Shisham being carried out in the Forest Genetics Section, F.R.L., Kanpur. The preliminary results indicate that there are advantages in Forest Tree Improvement Programmes.

Abstract

In taral region Intercropplng of some medicinal plants with Poplar as principal crop as carried out during 1987-89. Out of sixty-four species tried Acorus calamus. Adhatoda rasiea, Aloe barbadense, Artimicia vulgaris, Canabis sativa, Centella asiatica, Curcuma amada. C. longa, Cymhopogon winterianus, Cyperus. Scariosus, mimosa pudica, Piper longum, Solamum indicum, Veliveria zizanoides, Amomum subulatum, Calotropis giganlia, Cymbopogon jwarencusa, Ocimum sanctum, Plantago avataforsk, Valaerina wallichii and Zingiber officinale were found most suitable. The species which showed poor performance are Abrus precatorious, Cinnamomum zeylanicum. Cymbopogon martini, Mentha citrata, Premna latifolia, Salvadora oleoides, Tribules lerrestris. Wilhania somnilera and Woodfordia fruticosa. The growth of different clones of Poplar was found to be improved due to intercropplng operations. During the intercropping trial phenology of different medicinal species wso also studied.
