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.

    Studies on Screening of Soybean Varieties against Major Insect-Pests of Soybean [Glycine max (L.) Merrill]
    (COLLEGE OF AGRICULTURE, UMMEDGANJ, KOTA, 2021-01-27) GHOSALYA, MAHENDRA KUMAR; Patidar, B. K.
    The investigation on, “Studies on Screening of Soybean Varieties against Major Insect-Pests of Soybean [Glycine max (L.) Merrill”] was conducted at Agricultural Research Station, Ummedganj, Kota during kharif, 2019. Twenty three genotypes/varieties of soybean were sown to study of screening and relative resistance of soybean genotypes/varieties against insect-pests and to record relative per cent yield loss of different genotypes/varieties. During crop season, the peak incidence of B. tabaci and E. kerri in 36th SMW with mean populations of ranged from 4.00 to 7.50 and 4.00 to 7.00 per three leaves, respectively and highest mean incidence (7.50 B. tabaci per three leaves and 7.00 E. kerri per three leaves) was recorded on the variety JS 335 (C). The peak incidence of H. armigera, S. litura, C. acuta and S. obliqua in 37th SMW with ranged 2.00-3.33, 1.33-3.00, 1.67 to 3.50 and 0.83 to 1.83 larvae per mrl, respectively. The maximum incidence of H. armigera, S. litura, C. acuta and S. obliqua larvae was recorded on the variety JS 335 (C) with 3.33, 3.00, 3.50 and 1.83 larvae per mrl, respectively. Incidence of O. brevis reached to its peak in between 11.67 to 23.34 per cent plant infestation per plot in 39th SMW during kharif, 2019. At the peak damage of O. brevis, the maximum per cent damage 23.34 per cent plant infestation per plot was recorded in the variety of soybean JS 335 (C). On the basis of overall mean of observations, mean incidence of sucking insect-pests ranged from 1.83 to 4.30 B. tabaci and 1.63 to 3. 85 E. kerri per three leaves. On the basis of overall observations, mean incidence of larvae in between 0.76-1.90 H. armigera, 1.00 to 2.14 S. litura, 0.98 to 2.10 C. acuta and 0.57 to 1.31 S. obliqua per mrl. On the basis of overall observations of per cent damage was recorded by O. brevis in the ranged from 8.75 to 13.96 per cent plant infestation per plot. Among 23 promising soybean genotypes/varieties AMS 100-39, NRC 142, JS 97-52 were comparatively better against major insect-pests. The per cent grain yield loss in soybean genotypes/varieties was recorded ranged from 4.35 to 55.00 percent in different genotypes/varieties. The minimum percent yield loss (4.35%) was recorded in the soybean variety JS 97-52 (C) while, maximum yield loss per cent was recorded in the genotype of soybean MACS 1493 (55.00%). These genotypes/varieties further grouped in four categories based on Maximin-Minimax method. Two genotypes/varieties of soybean (genotype NRC 142 and variety JS 97-52 (C) were found resistant high yielding (R-HY), whereas five genotypes of soybean were showed resistant low yielding (R-LY). One soybean genotype AMS 100-39 was found susceptible high yielding (S-HY), while fifteen genotypes/varieties were found susceptible low yielding (S-LY) against insect pests of soybean.
