Studies on agro-forestry based on poplar plantation coupled with non-conventional crops like aromaric plants (Mentha spp and Cymbopogon spp) for three years revealed no adverse effect of companion aromatic plants on poplar growth measured in terms of height and diameter. Further, while the herb and oil yield of Mentha spp decreased as compared to their sole cropping in second and third year, that of Cymbupogon spp remained equally economical in all the three years of this study. Thus, the aromatic grasses particularly Java Citronella, Palmarosa and Lemon grass were proved to be the efficient companion crops under poplar based agro-forestry.

The suitability of poplar for agro-forestry was studied. The poplar plantation done in blocks or in a single row on field bunds, roads or along irrigation channels was found economical. In agro-forestry the trees attained economical growth in five year's period only with a net income of Rs. 22048/ha/year. Poplar trees grown along form boundaries/channels attained comparable growth within a period of three years as against five years period under agro forestry with a net income of Rs. 11067 in three years to Rs. 41250 in seven years. To make this programme endurable in the farming system, fresh planting of trees before the harvest of matured trees is recommended.- Evaluation of Essential oil in Eucalyptus Varieties Grown in Kumaon Hills (Ranikhed), Uttar Pradesh for Timber

Fourteen different Eucalypts grown in Kumaon Hills (Ranikhet) for timber were studied for their essential oils together with their. Growth parameters E. viminalls followed by E. microcorys was found to be the best for timber and all both, while E. robertsonli was the highest oil yielding species. Feasibility of storage of leaves in open natural condition before distilling was also studied by distilling one sample of one kg leaves regularly up to 61 days and it was found that up to 30 days of storing of Eucalyptus hybrid leaves did not affect the oil content significantly. The oil content declined gradually upto 40 days after which a sharp fall in the oil content was recorded.- Studies on Essential Oil Content of Eucalyptus Species Grown in Tarai Region of Uttar Pradesh, Nainital for Timber
