Niche differentiation is a prominent hypothesis explaining the maintenance of tree species diversity in tropical forests (Connell 1978). It suggests that different species are best suited to different habitats in which they are completely dominant and more abundant than in less suitable habitats (Harms et al. 2001). In addition, distribution patterns of tropical trees are generally more clumped or aggregated than random (Condit et al. 2000). Furthermore, environmental heterogeneity (difference in soil, elevation, slope, etc.

The main reason to study this area is to evaluate soil health status at various depth by analysing the physical properties of soil. So that to make recommendation towards achieving sustainable utilization and agricultural production. The most important reason for choosing this area is that as of very less research paper in this region most of the farmers are not aware about theresoil condition. Thus, still they are dependent on conventional method without implementing advance technology.

Mycorrhiza has drawn substantial attention because of their role in ecosystem restoration and in alleviating the adverse environmental conditions for plant growth. Arbuscular mycorrhizal fungi (AMF) are obligate mutualist biotrophs of more than 80% terrestrial plants including mulberry. Mulberry plants are generally raised in nutritionally poor soils, so AMF have notable role in their survival and establishment, provided appropriate AMF inocula conducive to the prevailing edapho-agroclimatic conditions are used.

A dynamic growth model (CO2FIX) has been used for estimating the carbon sequestration potential of Burans (Rhododendron arboreum), an indigenous medicinal plant of higher hills of western Himalayan region. The present study has been carried out in the campus of V.C.S.G. College of Horticulture, U.U.H.F., Bharsar, Pauri Garhwal, Uttarakhand. The temperature and rainfall of this hilly area ranged from - 4.0 to 28.0o c. It is capable of thriving on snow and heavy rainfall condition. CO2FIX was parameterized for a simulation of 50 years respectively.

For the past hundreds of year’s trees like Dalbergia sissoo (Shisham), Acacia nilotica (Kikar), Prosopis cinneraria (Khejri) etc. have inhabited vast areas in the plains of Afghanistan, Pakistan, India, Nepal and Myanmar. These have also been widely used for afforestation in many parts of the country except in the very hot, cold and wet tracts. These have good atmospheric N2 - fixing ability, therefore, are extensively planted in social and agro-forestry programmes. In order to evaluate the effect of soil salinity, present investigation was conducted on two tree species i.e.

Wheat (Triticum aestivum L.) production is often affected due to micronutrient status in soil. Micronutrient deficiency in soil including Boron is very much prominent in India, due to prevalent environmental and soil conditions (viz., wide variation in soil pH, organic matter, salt stress, supply of micronutrients etc.) among the various methods of incorporating micronutrients into the soil system, seed treatment with seed priming and seed coating are attractive, easy cost effective and beneficial over the soil and foliar application.

Present study was undertaken on the stem/root rot caused by Macrophomina phaseolina (Tassi) Goid of Brinjal (Solanum melongena) during 2015-16. A total of 10 amendments were evaluated as pre- sowing application against M. phaseolina (sick soil), sowing susceptible brinjal variety Rakesh in pot culture under glass house conditions. The average reduction in mortality (PESR and PESM) recorded with all the test amendments was ranged from 17.11 (FYM) to 66.96 (neem seed cake) per cent over untreated control. However, significantly highest reduction in average mortality (66.

Among the various fungal diseases affecting coconut palm, basal stem rot (BSR) or wilt or root rot caused by Ganoderma spp. viz., G. lucidum, G. applanatum G. boninense, etc., is the most destructive especially in the lighter soils of Andhra Pradesh. Keeping in view the minimal use of fungicides, the present investigation was taken up to develop an ecofriendly biocontrol management package against the basal stem rot disease by exploring the efficacy of native biocontrol agents under field conditions.

The protected cultivation of cucumber in soilless systems (substrate culture, hydroponic, aeroponic etc.) under optimal operating microclimatic conditions has become an alternative for sustainable vegetable production as a result of shifting climatic scenarios and soil related problems. The soilless cultivation in both open and closed systems with efficient utilization of water and nutrients has significantly increased the greenhouse cucumber productivity compared to conventional cultivation under both protective structures and open field conditions.

Agriculture is one of the significant contributors to the Indian economy. Growing a good crop depends on multiple factors like soil condition, climatic condition, rainfall, selection of good variety etc. and selection of crop plays a very important role in getting a good return. India has a unique position as a major supplier of seed spices in the international trade. Some major seed spices are Cumin, Coriander, Fennel and Fenugreek and minor seed spices are Ajwain, Nigella, Aniseed, Dill, Caraway, and Celery.

Fusarium wilt caused by Fusarium oxysporum f. sp. ciceris, one of the most important fungal pathogen of chickpea (Cicer arietinum L.), is a constant threat to this crop worldwide. It causes yield losses up to 100 % depending upon the varietal susceptibility, growth stage and climatic conditions. Strategies have been employed for controlling this pathogen such as use of cultural practices, resistant cultivars, fungicides etc., but have proven less effective and even the use of chemicals have hazardous effects, and also lead to the development of fungicide resistance in pathogens.

Wheat is an important cereal crop grown worldwide primarily for chapati, bread and biscuits. Target specific wheat breeding and quality improvement programs focus on developing genetically superior, high yielding, disease resistant cultivars with desired quality that are adapted to different growth environments. Drought refers to the condition of reduced soil moisture which induces several changes in crops i.e., morphological, biological, physiological and molecular changes. It also causes reduction in crop yield or in some cases cause crop failure.

Endophytes are microorganisms mostly bacteria and fungi that lives partially or completely its life cycle inside living plant tissue without causing adverse negative symptoms. Endophytes play a major role in structuring shaping processes of plant such as colonization, competition, coexistence and soil nutrient dynamics. Some endophytes promote growth of their host plants by enhancing the host‟s ability to take up nitrogen and phosphorus.
