Import into RefWorks 1. Introduction Agroforestry is a new name for the old practice, exceptionally common in the Garhwal Himalayan regions of India. The multifarious trees deliberately retained by the farmers on the farm bund forms the agroforestry combinations, which supplement the fodder, fuel, fiber, fruits and flosses as their life support system.

The unusually wide altitudinal range, rapid change in altitudinal gradient even at small distances and high endemism make it interesting for studies Singh and Singh, The increasing population is subsequently creating higher demands for the forest products and the alarming fact is that, even today the production from forestry sector is not enough to meet out the existing demands. The vegetation of the varying topography of the Garhwal Himalaya changes its species diversity, composition and structure along altitudinal gradient.

Moreover the direction of the sun aspect in the hilly topography also plays an important role in the vegetation and land use pattern. The season is also an important factor which decides the availability of fodder to the livestock of this region, hence some trees which are boon for the region provides the green fodder in the lean period.

Though there are many trees species in practice in the traditional Agroforestry systems in Garhwal Himalaya but some tree species are prioritized by the farmers for daily need and livelihood support. Grewia optiva, wonder tree of western Himalaya locally known as Bhimal is the most common multipurpose tree is the boon for the inhabitants of Garhwal Himalayan region. This tree abundantly grown on the farmers filed under traditional agroforestry along with most of the agricultural crops.

The G. The tree is also used for fuelwood purpose in the areas where no other choice of good fuel is available. The Land-use systems in the Himalayan region comprised of forestry, agriculture, horticulture and animal husbandry Sundiriyal et al. Beside, G. The productivity of wheat is usually reduced under tree cover but the additional benefits of G.

The agroforestry interventions seem to be more worthwhile due to the share of tremendous pressure on forest for the fuel and fodder by these farm trees. Although a number of studies on the Himalayan agroforestry systems Toky et al. This study aimed to analyse the wheat productivity as intercrop under G. Geographically the area falls in transition zone of sub-tropical and temperate zone, with majority of agricultural fields fall in high degree of terraced slopes, resulted soil and water losses.

The traditional agricultural fields are dominated with luxuriant and green lush natural vegetation. The soil of this region is acidic in nature varying in texture as per the availability of organic matter. Agricultural is the mainstay of livelihood of this region and the villagers are engaged in agricultural interventions all through the year which is usually low productive.

Majority of the farmers of this region are small with fragmented land holding around 0. The area receives an average annual rainfall of mm with most of the rain occurs during July to September monsoon period. The mean annual temperature of the area varies from 9 to 33C with occurrence of snowfall during November to February.

The elevation and aspect direction of sun light faced by slope play a significant role in growth, development and composition of vegetation in the hilly areas. It has generally observed that the tree and agricultural crops change their productivity in varying slopes and aspect with morphological changes in the plant characters.

The present study is planned in such a way that the feasibility of G. The effect on the productivity of wheat under G. Experimental Design The experiment was conducted in four experimental sites during Rabi November-March season in the wheat fields dominated by G.

The stratified random sampling was carried out in the area sample intensity 0. In each quadrat, the trees of different species were enumerated. Rino, Garmin. The composition of different agroforestry components were enumerated on the basis of population dynamics and functional diversity James, The elevation and aspect wise analysis was done to quantify the influence of physiographic variation on growth and yield of wheat under G.

In each study site, the G. In each sample plot, the diameter at breast height DBH of G. The diameter class was considered to be the major factor, influenced the growth and yield of wheat. The Crown spread CS of G. In case of wheat crop, the 1x1 m quadrat was laid for the same agroforestry field at different distances under the average canopy of G. The Crown spread of G. The wheat crop growth was studied along transects at 1 m D1 , m D2 , m D3 and m D4 distances from the G.

The different growth and yield attributes of wheat viz: number of plants, number of tiller per plant, plant height cm , thousand grain weights gm , grain yield, straw yield and biological yield was estimated under G. Statistically the study was tested in Factorial Analysis of Variance F-ANOVA to find out the effect of two or more than two factors in different study sites and level of significance was tested at probability levels 5 per cent as per the procedure outlined by Snedecor and Cochran The main factors considered elevation, aspect, and distance from tree trunk for wheat productivity estimation.

The productivity of sole wheat crop was performed in Randomize Block Design RBD and estimation was done in agronomical method. Results The results of the present study Table 1 showed that the G. The highest percentage of Stem Density G. The minimum percentage of Stem Density was observed in cm diameter class as 3. Table 1.
