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.

    Potassium pools in calcareous soil after seven year continuous fertilization under rice based cropping systems
    (DRPCAU, Pusa, 2020) Choudhary, Sarita; Singh, S.P.
    The different pools of potassium play important role in K contribution from soil to plants. Thus, a trial on “potassium pools in calcareous soil after seven year continuous fertilization under rice based cropping systems” was undertaken in randomized block design with three crop rotation (rice-wheat, rice-mustard and rice-maize) and nine treatments [T1- control, T2-FP, T3-GRD, T4-YT 35q/ha, T5-YT 40 q/ha, T6-YT 45 q/ha, T7-STCR (YT 35 q/ha) + IPNS, T8-STCR (YT 40q/ha) + IPNS, T9-STCR (YT 45 q/ha) +IPNS at Experimental Farm, RPCAU, Pusa, Bihar, during kharif-2019 under an ongoing long-term STCR trial. Continuous addition of STCR based fertilizer along with 5 tons compost ha-1 improved soil organic carbon, CEC and different potassium fractions over control, farmers‟ practice and general recommended dose treated plots. Negative potassium balance in soil was recorded under all the treatments and it was more pronounced in rice-maize cropping system than rice-wheat and rice-mustard cropping system. Treatment with STCR (YT 45 q/ha) +IPNS for rice based cropping system was superior over all the other treatments in potassium fractions, chemical and biological properties soil and potassium balance. A highly significant relationship was observed between organic carbon and CEC with among all potassium fractions except feldspars. The potassium in muscovite form dominates over biotite and feldspar K in surface and subsurface soils in all the three rice based cropping systems. Potassium present in different primary minerals varied in the order muscovite > feldspar > biotite in surface and subsurface soils in all three rice based cropping systems. The average contribution of biotite, feldspar and muscovite to total K in surface soils were 6 to 7, 33 to 46 and 48 to 60 percent in all the three rice based cropping systems. Thus, the present study indicate that long term continuous application of STCR based fertilizer with IPNS improved the potassium status and enhance microbial properties as well as potassium balance over FP and GRD in surface (0-0.15 m) and sub-surface soil (0.15-0.30 m).
