Abstract

Poplars are being increasingly used by the farmers of Haryana for raising short rotation, high yielding, industrial plantations in their agricultural fields. A number of poplar based agroforestry practices have been perfected by the farmers with regard to space and time sequence for the agricultural crops in order to optimise the economic returns, vis-a-vis the sustained utilization of the land resources. Poplars along with sugarcane, wheat and jowar constitute one of the most beneficial tree crop combination adopted by the farmers. A spacing of 5 m × 4 m has been found excellent for block planting whereas in row planting the trees are spaced at 1 m to 3 m apart. Poplars are known to give higher returns to the farmers as compared to other tree species.

Abstract

20 clones in line plantation and 10 clones in compact block plantation trials have been laid out in the farmers agricultural fields at Yamunanagar (Haryana) by planting the ETPs of poplar clones under the agroforestry extension programme of UNDP project. Early findings indicate that the clones S7C15, St-67, G-3. and G-48 are good for line plantation as well as compact block plantings where as row planting the clone S7C8 also has shown good results. Clones L-88 and L-89 also appear to h ave good potential for growth in row planting but need more care and maintenance as compared to other clones. The results also prove that timely planting and proper care of the plantation are sine qua non for successful agroforestry plantations based on poplars.

Abstract

Melampsora larici-populina, an internationally known damaging foliar rust of poplars, has been dealt with in detail with regard to its current status in the country as an immigrant pathogen of concern, taxonomy, damage and control in the nursery. Foliar application of Bayleton (0.08%) has been found to be most effective in controlling the rust infection.

Abstract

The article presents an accoqnt of experiment carried out in Poplar Research Nursery of Forest Research Institute, Dehra Dun with the ohjective to assess the effect of nursery conditions on performance of eight clones of Poplar. It was quite prominently observed that survival, height and diameter, of all the Poplar clones under study, suffered severely due to heavy shade and high soil moisture conditions. Clone 3650 experienced maximum setback and the clone CIMA expressed minimum effect. The study also brought out that growth pattern of Poplar clones underges changes with alterations in nursery conditions.

Abstract

The study is based on the visit of the Dzulo Valley by the Wildlife Wing of Manipur Forest Department for exploring it for the creation of a National Park. The valley, bordering Manipur and Nagaland states, presents a unique assemblage of fauna and flora which need protection by the government against human onslaught so as to preserve the rich germ-plasm in its ecological niche.

Abstract

Under the UNDP project the ICFRE has stated work on the socioeconomic upliftment of villages by incrasing the productivity through agrotorestry. Various institutes of ICFRE are engaged in the reaearch, demonstration, and the extension of agroforestry technology in about 100 villages all over India. The efforts of one of the institutes, viz., Forest Research institute Debra Dun have been summarised in the paper. The selection of villages, distribution of quality planting material, training, demonstration and extension of agroforeetry reeearch, impact and the likely changes in rural ocenario have been discussed.

Abstract

Investigations were carried out to study the effect of orientation and different ratio of soil mixture on germination behaviour of Quercus serrata seed in nursery. Three position of seed sowing I e, vertical (embryonic end upward and downward) and horizontal. Seeds were sown in four different ratios of soil mixture. Experiment coducted revealed that Quercus serrata seedlings could be raised by sowing the seeds in horizontal position in the soil mixture consisting of soil, sand aDd farmyard manure in 2:1:1 ratio in perforated polythene bags or in nursery beds for better germination.
