    Title: “Assessment of yield potential, carbon sequestration and economic benefits of wheat-Eucalyptus based Agroforestry system in sub tropicalCondition of Uttarakhand” The study entitled “Assessment of yield potential, carbon sequestration and economic benefits of wheat-Eucalyptus based Agroforestry system in sub tropicalcondition of Uttarakhand”. The objective were - to study about evaluating soil characteristics of wheat-Eucalyptus based agroforestry system, to determine biomass production and carbon sequestration of Eucalyptus-wheat based agroforestry system and to Study about yield attributes of wheat and economic benefit of Eucalyptus. A field experiment was carried in three different site viz., site-1(Kotdwar), site-2 (Doiwala) and Selaqui (Dehradun). The study carried four different distance from the tree base D1(distance from tree base - 1m), D2(distance from tree base-2m) and D3(distance from tree base-3m) to study about crop growth and yield of wheat under Eucaylptusbased agroforestry system. The study result demonstrated that the pH was slightly acidic to basic range. The soil organic carbon maximum showed at 0-15 cm soil depth at kotdwara (0.83) while in 30-45 cm soil the maximum OC recored at Doiwala (0.59).The maximum available nutrient recorded at site -1 followed by site-2 and minimum at site-3. The maximum height of crop observed at control in site -1 followed by site-2 and minimum at site-3. The grain yield gradually increased with increased in distance from the tree base. The maximum mean value observed at control 34.84q/ha and minimum mean value recorded at D1 (27.27q/ha). The plant height and grain yield, straw yield, biological yield and harvesting index was recorded maximum at site-1 in control condition followed by D3, D2 and minimum in D1. The plant height, grain yield, straw yield, biological yield and harvesting index was recorded minimum at site-3 in control condition followed by D3, D2 and minimum in D1. The growing stock, AGBD, BGBD, and TCD range from 43.62 to 40.70, 81.53 to 77.33Mg ha-1, 21.48 to 21.43Mg ha-1 and 52.03 to 49.04Mg ha-1. The maximum carbon density was recorded at site-1 (52.039Mg ha-1) and minimum recorded at site-3 (49.4091Mg ha-1). Thehigher B:C ratio (6.33) was obtained in Eucalyptus based agroforestry+ Wheat agroforestry system over (2.099) wheat control and 4.24 Eucalyptus cultivation.This indicated that Eucalyptus based agroforestry system economically benefits than open farming.

    The cultivation of tea depends greatly on the presence of shade trees. The shade trees are crucial for controlling the environment of the tea ecosystem because they improve soil fertility, lower temperature, lower evaporative capacity, and save soil moisture. Additionally shade has a variety of other advantageous benefits on physiological processes like photosynthesis, tea growth, and yield. The shade trees give the tea plants some partial shade, which is crucial for raising the standard of the tea leaf. Growing excellent tea crops requires the right kind of shade trees and their adequate maintenance.The current study was carried out in two Kumaon Himalayan tea gardens of Uttarakhandviz. Harinagri tea garden and Champawat tea garden, present at an elevations of 1346m and 1622m asl respectively. Both tea gardens were divided into four main plots for the study of the effects of various shade trees on tea growth. In the present study total of 9 shade trees were documented from both the studied tea garden and their effect on growth of tea was studied individually.Various tree parameters viz. height, diameter and crown spread were studied for the shade trees present in association with the tea crop. Inorder to study the effect of different shade trees on the tea crop, primary shoot height and bush surface area was studied for the tea crop. The production potential of both tea gardens was examined by gathering secondary data from Uttarakhand Tea Development Board, Champawat and Kausani offices. Primary data collected for the tea gardens revel that the Organic tea garden i.e. the Champawat tea garden had more plantations under it and hence more production of tea leaves and tea as compared to the Inorganic tea garden of Harinagri which was planted by the Kausani tea development board. Chlorophyll A, Chlorophyll B and total Chlorophyll of the tea leaves in the understory of associated trees were also studied for both the study site. Chlorophyll estimation revealed that Phyllanthus emblica is the most preferred shade tree for the Champawat tea garden and Grewia Optiva for Harinagri tea garden as the chlorophyll content of tea leaves in the understory is preferable over other shade trees. A comprehensive survey was conducted to examine the socioeconomic conditions of tea plantation workers with a particular focus on the female workforce. For socioeconomic study 50 women respondents were chosen from each tea garden the socioeconomic situation of tea workers and those who depend on them is neither very excellent nor very bad. Although the women workers in the tea gardens are permanent employees, they are paid on a daily basis, so they only receive compensation for the hours they really put in. The condition of women tea workers is more fragile if the tea garden is locked out or the job is temporarily interrupted, but it has been operating throughout the entire covid period, which has encouraged the locals to migrate less. In fact, reverse migration has been prominent in the past year.In light of all theoutcomes, the present study analyses the significance of shade trees in an agroforestry system in the studied tea plantations and gives an idea about the preferable and unsuitable shade tree species for the tea plantation.
