The Agriculture University, Kota (AUK) was established on 14th September, 2013 after bifurcation of the Maharana Pratap University of Agriculture & Technology (MPUAT), Udaipur and Swami Keshwanand Rajasthan Agricultural University (SKRAU), Bikaner through promulgation of Act No. 22 of 2013. The University has been created for the agricultural development in South-East and Eastern Rajasthan which is having diversified agriculture situations from rainfed to canal irrigated agriculture.
The Agriculture University has its Headquarter at Borkhera Farm, Kota & is located on Kota-Baran National highway-76. Kota district is situated in the South-Eastern part of Rajasthan and comes under Humid South-Eastern Plain Zone (agro climatic zone V). It lies between 23045’ and 26038’ North latitude and 75037’ and 77026’ East longitude. The jurisdiction of AUK is spread over in 6 districts namely Kota, Baran, Bundi, Jhalawar, Karauli and Sawai Madhopur. It accounts for 9.98 % geographical area, 12.67 % total human population, 9.4 % live stock population, 31.59 % forest area and 20.6 % net sown area of the state. Development and education of modern practices in the field of Agriculture, Horticulture & Forestry for sustainable livelihood of the rural masses is the main thrust of the service area of AUK.

The present investigation entitled as “Effect of growing media on germination and seedling growth of important agroforestry species of semi-arid region of Rajasthan” was laid out in CRD with three replications during June, 2019 to March, 2020 under the Instructional farm Fruit Science at the College of Horticulture and Forestry, Jhalawar, Agriculture University, Kota (Rajasthan). The experiment consisted of eighteen treatment combinations of four growing mediums of soil, sand, FYM and Vermicompost in different ratios. The study aimed to find out the best growing medium for following 3 species viz. Ardu (Ailanthus excelsa), Bael (Aegle marmelos) and Neem (Azadirachta indica) which are the main agroforestry species of the region. Seedlings were raised in the polybag of size 6” x 10” under green shade net nursery conditions. Different species exhibit different phenotypic and genotypic characteristics. Same can also be seen in preference of treatment combinations shown by species. Best growth of Ardu, Bael and Neem seedlings was observed in treatment T12 [Soil:Sand: Vermicompost (1:1:2)], T5 [Soil:Sand:FYM (1:1:2)] and T15 [Soil:Sand:Vermicompost (2:1:2)] respectively. These 3 treatment combination gave best germination attributes, height (38.7, 12.5 and 33.5) cm, collar diameter (7.92, 1.54 and 5.21) mm, number of leaves (11.50, 13.65 and 16.42), length of longest tap root (22.65, 10.96 and 17.55) cm, diameter of tap root (3.79, 1.83 and 2.91) mm ,fresh weight of seedling (58.67, 19.23 and 56.90) g, dry weight (27.15, 9.09 and 26.34) g, root-shoot ratio (1.09, 0.56 and 1.09), chlorophyll content (3.40, 3.23 and 3.63) mg/g, survival percentage (72.19, 62.31and 76.37) % and benefit-cost ratio of 2.23, 2.97 and 2.23 for Ardu, Bael and Neem respectively. The results obtained from this study can be used to produce quality planting material of Ardu, Bael and Neem in the shortest possible time.
