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.

    Impact of extrusion processing on physio-chemical and sensory attributes of broken rice - pearl millets and mushroom based extrudates
    (RPCAU, Pusa, 2023) Kumar , Mukesh; Sharma, P.D.
    The extrusion cooking process is a high temperature and short time process in which material is feed to the extruder for desired temperature, pressure, and residence time. Broken rice, Oyster mushroom and pearl millet was used to develop Ready- To-Eat (RTE) snack through extrusion cooking. Composite mixed flour was prepared using Broken rice flour, Oyster mushroom powder and Pearl millet flour. Broken rice and oyster mushroom powder proportion were fixed and only pearl millet flour in varying proportions. Extrusion cooking was carried out using a Twin-Screw Extruder. Extrusion cooking experiments were conducted employing CCRD for four independent variables with five level each feed proportion- 90:10, 85:15, 80:20, 75:25, 70:30; feed rate-6, 8, 10, 12, 14 kg/h; screw speed- 300, 325, 350, 375, 400 rpm; Barrel temperature 105, 120, 135, 150,165°C. A total 30 combinations of these independent variables were formed to see the effect on different dependent variable like Moisture content, Expansion ratio, Bulk density (kg/m3), Total colour index (E), Hardness (N) and Overall acceptability (OA). During experiments the best combination was generated on the basis of optimization by response surface methodology (Liang et al., 2012). Second order multiple regression equations were developed for all the dependent variables which were optimized using response surface methodology. The best product was prepared at optimum solution such as feed proportion- Pearl millet flour percentage 24.99% Feed rate - 8 kg/h, Screw speed 307 rpm and Barrel temperature 150°C, produced the most acceptable extrudates. The experimental data for response were in close experiment with the optimized solution obtained from RSM. Moisture content 6.2 %, expansion ratio 3.6, bulk density 113.3 kg/m3, hardness 6.24 N total colour index 75.29 and 7.5 overall acceptability. The prepared optimized extrudates also had well balanced acceptable range of the nutrition (moisture content 6.20%, total carbohydrate 81.02%, protein 9.92, fat 0.87, fibre 2.10% and ash content 1.49%.
