Agriculture University, Kota

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.

    Survey and Evaluation of Selected Big Size Trees (BSTs) Quality andVigour by External Characteristics in Jhalawar Region
    (College of Horticulture and Forestry, Jhalawar, 2021-03-15) Vaishnav, Ramniwas; V.C., Prahlad
    A field experiment entitled “Survey and Evaluation of Selected Big Size Trees (BSTs) Quality and Vigour by External Characteristics in Jhalawar Region”was carried out during the year 2019-2020 in three different locations (L1-Residential,L2-Farmland and L3-Roadside) at four sites ( S1-Jhalawar, S2-Aklera, S3-Khanpur and S4-Pidawa) of Jhalawar district. Total 27 species covering 240 trees (>50cm DBH)where Pipal (24.69%), Mango (22.22%), Neem (19.75%), Mahua (19.75%) and Tamarind (13.58%) count 162 which form 67.50% to the total tree counts. These five dominant tree species are indigenous, multipurpose and sacred in nature. The IVI was reported for Pipal(55.9), Mango (39.03), Mahua (36/67), Neem (34.47) and Tamarind (27.62) restively. Species richness index showed highest 2.19 at S4L1 and lowest 1.68 for S4L2 and less at S1 in general. Regarding ANOVA reported for bole and crown parameters, Tamarind for height, Pipal for Bark and crown width, Mahua for Crown length showed significant variation at P<0.05 level while except mango all other dominant species showed significant variation for crown height. Remaining other bole and crown parameters did not show significant variation in our study. In current study 199 trees (82.91%) to the total surveyed 240 trees no PBM were reported but 76-100 cm and 101- 125 cm and 126- 150 cm DBH were reported 25- 50 % PBM category found primarily vulnerable accounting 13.75 %. About half of the total number of trees reported PBM were from roadside locations suggest their vulnerability to anthropogenic disturbances. Among the 120 (50%) trees reported formation of buttresses from different families prominently from the trees of greater Height. Trees of 76-100 cm and 101- 125 cm accounts 70 % of the buttress formation again vindicates the vulnerable size class. Maximum Leaf area is recorded for Azadirachta indica. 121 (50.41%) trees were reported knots forming where Mahua (261), neem (174), mango (95) and tamarind (83) forms total 74.30% of number of knots to the total and these are the species also reported relatively higher primary branch mortality. Around 35.53% of knots forming trees found at Roadside Locations are subject to heavy disturbances and injury. Regarding preferred height of knots formation upto 2 m and 2-5 m found dominant. Among the 169 total no. of snags observed from 51 (91.07%) number of trees mango, mahua and tamarind contributes 69.82% to the total number of snags. The good number of snags found at 2-5m above the ground. ThePipalshowed highest EC and BD and lowest pH, while tamarind showed lowest for SM, OC and litter deposition. Whereas, Mahua showed highest SM% and SOC%, mango reported highest litter and lowest EC and BD respectively. Keywords: BST, Large trees, Tree quality and Vigour,
