Abstract

Forestry activities in semi-arid regions of Uttar Pradesh are of great importance to meet the fuel, fodder and timber demand of local people. An international trail of dry zones hardwood species was carried out in Vrindavan forest block, Mathura, for screening a wide range of species, suitable for use in rural afforestation schemes and agroforestry systems. The results of the 8 year old trial showed that species adapted for region are Guazuma ulmifolia, Senna atomaria, Caesalpinia velutina , Parkinsonia aculaeta, Gliricidia sepium, Leucaena leucocephala, Mimosa tenlliflora, Caesalpinia coriaria etc. Most of these species are nitrogen fixing legumes and hence will be useful in improving the soil characteristics.

Abstract

Cones of radiata pine or Pinus radiata are serotinous. The cone scales are stuck together by resin making natural seed release impossible for many years. In the present study cones were subjected to various heat treatments viz. Heated in a kiln at 65°C for 8 hours, heated in a microwave oven set at high poser for 60 seconds or submerged in boiling water of 120 seconds. Subsequent rate and extent of seed release was observed on day 1,3,6 and 7. Maximum and quickest seed release was observed following the kiln treatment. Seed viability assessed by Tetrazolium Test (TZ) and relative seed vigour assessed by Accelerated Aging (AA) test both showed that seed extracted by the kiln method was superior to that obtained by either of the other two methods. The effectiveness of suitable methods of extraction of seeds from cones of P. radiata in the light of economic importance is discussed.

Abstract

Three species of Acacia were grown using a range of P rates in a peat/sand (1:1) media. Seedlings were grown in 1 litre pots in a greenhouse. Severe P toxicity occurred in A. baileyana and A. cardiophylla when P rates supplied from 5-6 month, Osmocote 0-18-0 fertilizer exceeded 20g P/m³/month. Toxicity was indicated by severe stunting and often iron chlorosis of the tip growth. The third species was A. pravissima which was tolerant of P levels approximately double (and even higher) those tolerated by the former species. All three species showed increases in the growth parameters measured of stem diameter, height and foliar dry matter when the P application was increased from nil to 10g P/m³/month.

Abstract

Mean crown diameter showed significant correlation with mean tree volume in man-made (Teak and Sal) and natural (dry and moist deciduous) forests. The value of correlation coefficient ("r") between mean crown diameter and mean tree volume was close to the value of "r" between DBH and mean tree volume. Regression equations were also developed and the predictive performance of the equations evaluated. It was concluded that mean crown diameter may be used to estimate mean tree vol ume in the above type of forests, as the growth of the tree is also reflected in the growth of the crown spread. Hence, it may be a good measure to estimate tree volume. It is therefore suggested that mean crown diameter may also be considered an important parameter in forest mensuration.

Abstract

Various kinds of industries use engineering to generate and maintain economy in the country by creating goods and services. The responsibility of academia is to provide quality-engineering education, so that the graduates are able to perform as per the requirement of industries. It is assumed by academic world that engineering education system is developing the required abilities in degree pass outs, while the industries have always complaining about the quality of fresh graduates. In USA, researches are being conducted by academia to find out the extent of satisfaction on the abilities being developed in fresh graduates. The regular feedbacks are being sought from the world of employment on extent of development and further requirement of abilities. In our country, these kinds of researches need to be conducted continuously to improve the quality of education.

Abstract

Students prefer mechanical engineering as career in colleges, for want of better and vast job opportunities. Once, they are on the verge of leaving colleges, what are the effects of mechanical engineering education on them, in terms of industry placement, graduates' choice of mechanical engineering subjects, preference for higher studies in engineering, and choice of working in a particular area in industry, etc. This study has tried to explore these aspects, which affect the graduates, industries and society, subsequently. The results are inadequate placements, lack of inspiration for core mechanical engineering subjects, less inclination for higher education in mechanical engineering and unfulfilled choices for work areas in industry.
