In India, natural forests are being conserved primarily for the environmental benefits. Serious efforts are also being done to plant large number of trees outside forest under social forestry programs to increase the tree cover and fulfill demand of various forest produce required by the people and forest based industries. Agricultural fields are one of the potential areas, where large scale planting of trees can be taken up along with the agricultural crops. Agroforestry models adopted by the farmers in Haryana and Uttaranchal states of India are highly lucrative, therefore, attracting farmers in a big way. NPV for different models on six years rotation varies from Rs. 26,626 to Rs. 72,705 ha-1 yr-1 whereas Benefit-Cost ratio and Internal Rate of Return vary from 2.35 to 3.73 and 94% to 389% respectively. Agroforestry has not only uplifted socioeconomic status of the farmers but also contributed towards overall development of the region.

Agroforestry in India has been identified as a potential practice, which can contribute significantly in increasing tree cover; meeting people's requirement of fuel wood, fodder, timber and non timber forest products. It can also ensure supply of raw material to the forest based industries and creating large scale employment opportunities. The present article discusses as to how a well-planned and systematic approach in agroforestry extension can attract farmers to adopt agroforestry practices and initiate a diffusion process, under which the practice spreads by itself due to its inherent virtues. About nine years back agroforestry was in its infancy stage, when the systematic and intensive extension works were initiated in Yamunanagar District of Haryana State. Today, on an average 30% of the total income of a family comes from agroforestry. This additional income has brought radical changes in the social life of rural people. They enjoy better education and have access to basic and modern amenities. Farmers with big land holdings have been benefited most by the agroforestry extension work. There is a need to chalk out special programme for development of agroforestry on the lands of small and marginal farmers.- Influence of Eucalyptus Shelterbelt on Fodder Crop (Sorghum vulgare)

In Northern India, use of Eucalyptus as windbreak/shelterbelt is well accepted but questions concerning the economic impact on crop production system requires through investigations. In this study, the influence of Eucalyptus trees on agriculture crop viz., Sorghum vulgare in terms of plant density, crop height and fodder yield were found negative in the vicinity of tree. Gross income from Eucalyptus trees for 100 m tree line estimated to Rs. 2144 for 61.35 trees in east-west and Rs. 2399.87 for 74.68 trees in north-south tree line. It was concluded that growing Eucalyptus on field boundaries under irrigated condition had very little impact on associated Sorghum crop and the crop losses due to tree line are well compensated by the income received out of sale of trees.- The Growth and Yield of Wheat and Paddy as Influenced by Dalberg1a sissoo Roxb.

Agroforestry studies using Dalbergia sissoo were conducted to assess the crop productivity under semi-arid conditions. Growth performance of D. sissoo trees intercropped with wheat and paddy showed mean height and gbh as 10.36 m and 53.45 cm, total timber 1.2554 m3 small timber 7.0899 m3 and fuel wood 77.45 q. The gross income from trees calculated as Rs. 24,056.00 for 33 trees pcr 55 m tree line. Crop yields and other crop parameters of wheat especially under tree canopy upto 4 m from tree line declined significantly. In case of paddy such influence was found upto 8m from tree row. The total affected area in the entire plot worked out to 220 m2 in wheat crop and 440 m2 in paddy crop showing a nct loss of 21.23 kg (Rs. 53.00) and 101.20 kg (Rs. 559.00), respectively. The losses to agriculture crops are wen compensated by the gross income Rs.2005/-per year obtained through sale of trees. The conclusions drawn from the studies indicate that D. sissoo trees though effect negatively the agriculture production in the vicinity of tree canopy but it proved viable proposition for practicing as a agroforestry tree species under irrigated conditions. The spacing between trees, pruning and manipulation of crown structure are crucial for minimising the tree losses and increasing the productivity per unit area.- Influence of Oak and Pine forests on the Productivity of Wheat and Paddy in Hilly Area of Uttarakhand

Oak (Quercus leucotrichophora ) and chir pine (Pinus roxburghii. Sarg.) are the main tree species in hills of Uttatakhand. Ecologically they also show some climatic effects in adjoining area. It is a well known fact that the area of chir pine forests shows dryness while in oak forest area moisture contents are generally high. Due to the variation of moisture in these forest areas, agriculture crops in adjoining to these forests are also influenced up to an extent.
A study on production of wheat and paddy near oak and pine forests in Uttarakhand was conducted and the yield of both wheat (Triticum aestivum) and paddy (Oryza sativa) was compared to the yield of these crops of non forest area far away from these forests. The study on crop yield was done in irrigated and rainfed land. The results show that there is no remarkable deference in yield of wheat and paddy near both the forests. But the condition of irrigation is found always a factor in crop yield. In other words we can say that the crop yield significantly more in irrigated land.

An experiment was conducted on agri-silvi-medicinal agroforestry in degraded lands at Naukragrant, Haridwar (Uttarakhand) and Handesra, Mohali (Punjab) during 2011-13. Six months aged seedlings of Melia composita and Emblica officinalis were planted at 6 x 4 m spacing and medicinal plants namely Rauvolfia serpentina and Withania somnifera were cultivated at 60 x 60 cm spacing as an intercrop along with seasonal agriculture crops like masoor and groundnut.
Soil pH organic carbon and available nitrogen, phosphorus, potassium and height and collar diameter of Melia composita and Emblica officinalis were observed. Initially, soil was slightly alkaline with pH values (8.20 and 8.18) at sites Naukragrant and Handesra respectively. The average soil pH was found neutral (7.18) at site Naukragrant and slightly alkaline (8.01) value showed at site Handesra after one year of plantation. The organic carbon, available nutrients (nitrogen and phosphorus) values indicates increases at both sites and highest values found at site Naukragrant as compared to site Handesra.
The growth parameter both of height and collar diameter of Melia composita and Emblica officinalis showed increase along with cultivation of agriculture crops and medicinal plants at both sites. The maximum increase in height (47.33 cm) and collar diameter (3.89 cm) of Melia composita with agriculture crops was observed at site Naukragrant in comparison of height and collar diameter in control plot. Similarly the maximum increase in height (29.67 cm) of Emblica officinalis with Sarpgandha at site Handesra and collar diameter (1.78 cm) of Emblica officinalis with Ashwagandha was observed at site Naukragrant with regard to height and collar diameter in control plot. The minimum increase in height (1.11 cm) of Emblica officinalis with agriculture crops at site Naukragrant and (1.89 cm) of Melia composita with agriculture crops at site Handesra with regard to control height was also observed. It may be due to closer competition in nutrients uptake by agricultural crops in comparison to control.

The study is the outcome of current status and economic evaluation of Poplar based agroforestry practices followed by farmers in Haridwar and Yamunanagar. Tree species like Populus deltoides, Eucalyptus spp., Mangifera indica and Dalbergia sissoo, were dominant species of commercial agroforestry. The patterns of planting were block (53.74%) and (88.47%) followed by boundary plantation (46.26%) and (11.53%) in Haridwar and Yamunanagar districts respectively. Composition of different species was poplar (77.12% and 90.64%) followed by eucalyptus (18.26% and 7.92%), mango (3.36% and 0.72%) and others (1.26% and 0.72%) in Haridwar and Yamunanagar districts. The net return from block system (Rs.1,96,950) ha-1 annum-1 was found higher than the bund system (Rs.1,02,249) ha-1 annum-1 in agri-silviculture system. The net return from tree produce (Rs.1,48,067) ha-1 annum-1 in block system was higher than the bund system of (Rs.48,883) ha-1 annum-1 respectively. In commercial region, B:C ratio was found higher for poplar based agrisilviculture block planting (3.85) than Poplar based agri-silviculture bund system (2.22). Comparatively as per net returns and B:C ratio the block systems were found more economic to bund systems. Therefore, commercial agroforestry seems better promising as compared to traditional agroforestry, and also relevant to the farmer's livelihood.Keywords
