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.

    EPIDEMIOLOGY AND MANAGEMENT OF STEM NECROSIS DISEASE OF POTATO IN SOUTH-EASTERN RAJASTHAN
    (COLLEGE OF AGRICULTURE, UMMEDGANJ, KOTA, 2021-12-06) MEENA, MAHESH KUMAR; Yadav, D. L.
    Potato stem necrosis disease is serious problem in the early planted potato crop and it caused by a tospovirus which transmitted through Thrips palmi. Initially brown necrotic spots were appeared on young stem, veinal necrosis on abaxial side of leaf, blacking and collapse the entire stem with necrosis in concentric patterns with dark necrotic lesions covered the stem. Maximum disease incidence was recorded in Suvana village (22.5%) of Kota district and 21.5 per cent in Anta village of Baran district. Whereas, minimum PDI was observed in Arjunpura (8.5%) and followed by Chandresal village of Kota (9.5%). Out of three dates of planting, maximum disease incidence was recorded in 1st and 2nd date of planting i.e. 10th October, 2019 and 20th October, 2019. While, minimum was observed in 3rd date of planting (30th October, 2019). 63.16 % yield reduction was recorded at 5 grade of stem necrosis disease in field condition during experiment. The correlation between the disease incidence and weather factors revealed that maximum and minimum temperature was highly significant with positive correlation in all four varieties i.e. K. Bahar, K. Sindhuri, K. Pukhraj and K. Pushkar in first date of planting (10th Oct 2019). Similarly, the correlation between the thrips population and weather factors revealed that maximum and minimum temperature was highly significant with positive correlation in all four varieties in first date of planting. The correlation between the stem necrosis and thrips population was observed highly significant with positive correlation. Highest AUDPC value was found in 1st date of planting in all four varieties. However minimum AUDPC was recorded in 3rd date of planting in all four varieties i.e. K. Bahar (180.25), K. Sindhuri (162.75), K. Pukhraj (217.00) and K. Pushkar (197.75), respectively. Maximum total number of tubers, marketable yield and total tuber yield (q/ha) was observed in 3rd date of planting. Foliar spray of fipronil 5% SC @ 1.5 ml/lit was recorded maximum per cent disease control (85.97%), minimum per cent intensity (4.66%), total number of tubers (498.67/plot), tuber yield (210.8 q/ha), marketable yield (184.9 q/ha) along with net gain (Rs/ha) 55398. Next best treatment in order imidacloprid 17.8% SL (0.3 ml/lit) combined with mancozeb 75 WP @ (2 gm/lit) of water. However, maximum disease intensity (32.22%) was recorded in control.
