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.

    Biology of Meloidogyne graminicola on rice (Oryza sativa L.) Under Bihar condition and its integrated management
    (DRPCAU, Pusa, 2020) Goud, Gajja Bharath; Keshari, Nishi
    Paddy is the main crop in Bihar during kharif season. Farmers in Bihar are growing different varieties under rainfed condition. The crop is infested by many pests, diseases and nematodes. Amongst the plant parasitic nematodes, the root knot nematode, Meloidogyne graminicola was found one of the main limiting factor of its production. In the areas where the rice is growing as a monoculture during kharif season, the infestation percentage is very high. The present investigation is carried out during Kharif 2019 to survey the rice root knot nematode infestation in different districts of Bihar in rice nurseries. The root and soil samples of the crops were brought from the rice field from the different villages of Samastipur, Muzaffarpur, Darbhanga and Vaishali districts. It was found that the frequency of occurrence of M. graminicola ranged between 80-90 % in these three districts. Maximum nematode population, number of females, eggs and juveniles was in Samastipur district and minimum infestation is in Darbhanga district. vii With the increase in inoculum density level level from 10J2/pot to 10000J2/pot, plant growth parameters decreased significantly and nematode multiplication parameters increased significantly. The maximum galls per roots system, eggs and juveniles per eggs mass, nematode population/200cc soil, root knot index and number of females per gall were increased significantly with increase in inoculum level and maximum was at 10000 J2 /pot. Among rice varieties screened against M. graminicola significantly highest root knots per plant, number of females per root knot, eggs and juvenile per egg mass and root knot index were recorded highest on PB1121 (check) and lowest root knot index was observed on Rajendra saraswati. Among millets, finger millet (RAU-1), Barnyrard millet (Dholi-1) and finger millet (RAU-3), (RAU-8) and foxtail millet (RAU-8) did not reveal any gall on there roots. Except onion no other vegetable revealed any sign of host parasite interaction on the host neither root knots nor females inside the root. Meloidogyne graminicola completed its life cycle from J2 to J2 is 33 days, during the study temperature was recorded at 8° C to 22°C. The fungal biocontrol agent, Trichoderma viride @ 5g, 6g, 7g, 8g, 9g and 10g/pot with carbofuran @ 2kg a.i./ha as treated check and another untreated check in 1 kg soil were taken and the effect was reported on the plant growth parameters and nematode multiplication parameters, keeping two sets as pre and post application of T. viride, one week before and after germination respectively. Although carbofuran treated plants have shown significantly highly effective treatment but among the different doses of T. viride in both pre and post treatment, the highest dose i.e, 10g/pot has given the maximum growth parameters and minimum nematode multiplication parameters in both pre and post treatments. When we compared the results in both pre and post treatments, it was found that in all the characters, the increase was more in pre treatment than post treatments.
