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.

    Incidence and Eco-friendly management of root knot nematode, Meloidogyne incognita infesting carrot
    (DRPCAU, PUSA, 2021) BARMAN, DEBANJAN; Singh, Uma Shankar
    The carrot (Daucus carota sub sp. sativus) is a root vegetable that can be purple, orange, red, white or yellowish. The tap root is the most widely consumed component of the plant, although the stems and leaves are also consumed. Vit-K and Vit-B6 are abundant in roots of carrot and it also contain a lot of beta carotene. Meloidogyne incognita, has been identified as a major impediment in effective carrot production. Annually, 20-25% loss is incurred due to Meloidogyne sp. infestation in carrot. According to a survey done in several areas of Samastipur district of Bihar, Meloidogyne sp. has been found to infect carrot crops in all of the locations. The greatest prevalence of was found in the Hi-tech horticulture, Pusa (1220), while the lowest was found in the Sugarcane Research Institute (SRI), Pusa (640). Other plant parasite genera found in the rhizosphere of carrot crops were Hoplolaimus sp., Helicotylenchus sp., Pratylenchus sp., Tylenchorhynchus sp., and Xiphinema sp. The mean root knot index (RKI) was 2.17 on a scale of 1 to 5, suggesting that carrot plants planted in all areas were moderately resistant to the root knot nematode (Meloidogyne sp.), according to Hartman and Sasser (1985). According to life cycle research, J2 of Meloidogyne incognita was infective juvenile stage and penetration begins in the zone of elongation of root tips within 24 hours of inoculation. At an average temperature range of 17°C to 20°C and a Relative Humidity of 94 percent, the life cycle of the southern root knot nematode (Meloidogyne incognita) in carrot was completed in 30 days. From the Meloidogyne incognita management study, suggesting that management with Neem leaves + Phyllanthus amarus leaves @ 100 +100 g / pot followed by Phyllanthus amarus leaves @ 100 g / pot enhanced characteristics of growth viz. Shoot length or plant height, root length, shoot weight (fresh and dry), root weight (fresh and dry), yield and effectively reduced the numbers of galls, juvenile population in soil. So, the management by using plant parts and extracts can be used by farmers for root knot nematode control, as it is an environmentally friendly, economically feasible method and had the same effects as Cartap hydrochloride 4G used.
