Dr. Rajendra Prasad Central Agricultural University, Pusa

In the imperial Gazetteer of India 1878, Pusa was recorded as a government estate of about 1350 acres in Darbhanba. It was acquired by East India Company for running a stud farm to supply better breed of horses mainly for the army. Frequent incidence of glanders disease (swelling of glands), mostly affecting the valuable imported bloodstock made the civil veterinary department to shift the entire stock out of Pusa. A British tobacco concern Beg Sutherland & co. got the estate on lease but it also left in 1897 abandoning the government estate of Pusa. Lord Mayo, The Viceroy and Governor General, had been repeatedly trying to get through his proposal for setting up a directorate general of Agriculture that would take care of the soil and its productivity, formulate newer techniques of cultivation, improve the quality of seeds and livestock and also arrange for imparting agricultural education. The government of India had invited a British expert. Dr. J. A. Voelcker who had submitted as report on the development of Indian agriculture. As a follow-up action, three experts in different fields were appointed for the first time during 1885 to 1895 namely, agricultural chemist (Dr. J. W. Leafer), cryptogamic botanist (Dr. R. A. Butler) and entomologist (Dr. H. Maxwell Lefroy) with headquarters at Dehradun (U.P.) in the forest Research Institute complex. Surprisingly, until now Pusa, which was destined to become the centre of agricultural revolution in the country, was lying as before an abandoned government estate. In 1898. Lord Curzon took over as the viceroy. A widely traveled person and an administrator, he salvaged out the earlier proposal and got London’s approval for the appointment of the inspector General of Agriculture to which the first incumbent Mr. J. Mollison (Dy. Director of Agriculture, Bombay) joined in 1901 with headquarters at Nagpur The then government of Bengal had mooted in 1902 a proposal to the centre for setting up a model cattle farm for improving the dilapidated condition of the livestock at Pusa estate where plenty of land, water and feed would be available, and with Mr. Mollison’s support this was accepted in principle. Around Pusa, there were many British planters and also an indigo research centre Dalsing Sarai (near Pusa). Mr. Mollison’s visits to this mini British kingdom and his strong recommendations. In favour of Pusa as the most ideal place for the Bengal government project obviously caught the attention for the viceroy.

    BIO-INTENSIVE MANAGEMENT OF MUSTARD APHID Lipaphis erysimi (Kalt.)
    (RPCAU, Pusa, 2023) SINGH, HAMENDRA; Mukherjee, U.
    The present investigation entitled “Bio-intensive Management of Mustard aphid Lipaphis erysimi (Kalt.)” was conducted during 2022-23 cropping season at Research Farm of Tirhut College of Agriculture, Dholi, Muzaffarpur, Bihar. The study focused on evaluation of 42 Brassica genotypes for their Resistance or susceptibility against mustard aphid (Lipaphis erysimi) and to check the efficacy of some botanicals and entomopathogens against mustard aphid population in field conditions. During the screening of 42 Brassica genotypes, overall mean population of aphids per top 10 cm of inflorescence ranged from 41.82 to 137.79. The genotypes KMR(E) 21-1 and KGMH 9198 were infested with minimum and maximum numbers of aphid population, respectively. whereas, susceptible and resistant check varieties Yellow sarson (66-197-3) and Kranti had aphid population of 137.48 and 43.48 aphids/top 10 cm of inflorescence, respectively. Based on aphid infestation index (AII), 42 genotypes were categorized into five groups viz. highly resistant, resistant, moderately resistant, susceptible and highly susceptible. Two genotypes were grouped as resistant. 11 genotypes as moderately resistant, 25 genotypes as susceptible and 4 genotypes were grouped as highly susceptible. The lowest and highest AII was recorded in KMR(E) 21-1 (1.43) and KGMH 9198 (4.03), respectively. Check varieties Yellow sarson (66-197-3) and Kranti had aphid infestation index of 3.54 and 1.96, respectively. Further phenol and total sugar contents of top six promising genotypes also shown the negative and positive correlation of the aphid infestation. Molecular identification proved the east Asian strain of mustard aphid i.e., Lipaphis erysimi pseudobrassicae. The efficacy of various entomopathogens and botanicals was also evaluated against mustard aphid and its natural enemies. Among the entomopathogens and botanicals tested on mustard aphid, the per cent reduction of mustard aphid population over untreated control following the first and the second spray was the highest in Verticillium lecanii @ 5g/liter of water that is (85.33) followed by Beauveria bassiana @ 5g/liter of water (84.5%) and Metarhizium anisopliae @ 5g/liter of water (84.06%), Onion bulb extract @5% (77.24), Garlic bulb extract @5% (75.54) and Ginger rhizome extract @5% (74.11) respectively besides with higher population of natural enemies. However, chemical check Dimethoate 30EC @ 1ml/liter of water showed 93.8% reduction over control. Additionally based on B: C ratio Verticillium lecanii @ 5g/liter of water 2.24:1 was found to be better followed by Beauveria bassiana @ 5g/liter of water (2.20:1) and Metarhizium anisopliae @ 5g/liter of water (2.18:1).
