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.

    Yield maximization through agronomic management in mungbean (Vigna radiata L.) under rice based cropping system
    (Dr.RPCAU, Pusa, 2022) Singh, Ankit; Singh, Harendra
    A field experiment was carried out during the two consecutive Zaid and Kharif seasons in the years 2020–2021 and 2021–2022 at the research farm of Tirhut College of Agriculture, Dholi, Muzaffarpur (Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar) to study "Yield maximization through agronomic management in mungbean (Vigna radiata L.) under rice based cropping system’’. The experiment was laid out in a factorial randomized block design with three replications having different factors like:-Seed inoculation with Rhizobium + PSB (Local) and LSMR 1 (Stenotrophomonas maltophilia) + RB 3 (Microbial consortia), weed management: weedy check, two-hand weeding at 20 and 40 DAS, propaquizafop 2.50% + imazethapyr 3.75% ME @ 125g/ha and fomesafen @ 220 g/ha + fluzifop-p-butyl @ 220 g/ha at 18 DAS, and foliar nutrition: water spray, urea spray 2% and 19:19:19 NPK at 2% at Flower initiation and Pod initiation. All treatments were compared with absolute control. This study revealed that when the seed was inoculated with LSMR 1 (Stenotrophomonas maltophilia) + RB 3 (Microbial consortia) in the green gram rice based cropping system and then foliar application with 2% 19:19:19 NPK (Flower initiation + Pod initiation) on the growth and yield of mungbean, the highest grain yield was found among all other treatments. Nevertheless, in terms of foliar nutrition, the 2% urea spray (Flower induction and pod induction) was found to be equal to the 2% 19:19:19 NPK (Flower induction and pod induction). As for the yield attributes and the availability of N.P. and K in soil, they followed the same pattern as the grain yield in both the years (2020 and 2021) and in the pooled data as well. In a green gram rice based cropping system, weed management done by two-hand weeding at 20 and 40 days after sowing and on the growth of mungbean notably resulted in the highest grain yield and minimum weed dynamics compared with all other experimental combinations. At the same time, propaquizafop 2.50% + imazethapyr 3.75% ME at 125g/ha at 18 DAS showed a similar response to two-hand weeding at 20 and 40 DAS in both the years (2020 and 2021), and on pooled data respectively. The yield attributes and availability of N.P and K followed the same pattern as that of grain yield in each year (2020 and 2021) and pooled data, respectively. However, the result of seed inoculation with LSMR 1 (Stenotrophomonas maltophilia) plus RB 3 (Microbial consortia), as well as two hand weeding at 20 and 40 days after seeding, the residual effect of mungbean on rice crop growth and yield were found to be significantly higher. In terms of foliar nutrition, it was found that there was no significant difference between the treatments in both the years (2020 and 2021) as well as pooled data. LSMR 1 (Stenotrophomonas maltophilia) + RB 3 (Microbial consortia) as seed inoculant followed by propaquizafop 2.50% + imazethapyr 3.75% ME @ 125g/ha at 18 DAS and foliar spray of 2% 19:19:19 NPK at flower initiation + Pod initiation were recorded as the most profitable in terms of net return and B: C ratio with the mungbean crop. In case of rice, significantly higher net return and B: C ratio were recorded in two hand weeding at 20 and 40 DAS, followed by LSMR 1 (Stenotrophomonas maltophilia) + RB 3 (Microbial consortia) and 2% 19:19:19 NPK at (Flower initiation + Pod initiation) in each year (2020 and 2021) and pooled data respectively.
