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.

    Studies on life table and Efficacy of different edible/non edible oils against Callosobruchus chinensis L. on mung bean
    (DRPCAU, PUSA, 2021) C, RAVIVARMAN; Rai, A. K.
    The studies on life table and efficacy of different edible/non-edible oils against Callosobruchus chinensis L. on mung bean were conducted under laboratory conditions in the Department of Entomology, DRPCAU, Pusa, Samastipur, Bihar during year 2021. The mean number of eggs laid per female were 52.05 eggs per 100 seeds. The net reproductive rate (11.84 females/female), mean length of generation (42.80 days), intrinsic rate of increase (0.0577 females/♀/day), finite rate of increase (λ) (1.060 females/♀/day), doubling time (11.896 days), weekly rate of increase (1.504 times) and hypothetical F2 females (140.18) were calculated in age specific life table of population concern. The k value (mortality) was observed in egg stage (0.0862) followed by larval (0.075) and pupal (0.068) period. The K value (mortality) was 0.2291 in stage specific life table. The maximum size was measured in chickpea 58.22 mm2 that had grain damage and weight loss percentage as 33.80 and 38.87, respectively. The size of pigeonpea was measured as 34.84 mm2 with its grain damage and weight loss percentage was 42.00 and 35.86, respectively. Size of the pea grain was measured as 48.39 mm2 that was having the grain damage and weight loss as 59.80 and 46.24 per cent, respectively. The lentil was having lowest grain size as 12.22 mm2 with its grain damage and weight loss as 4.40 and 3.38 per cent, respectively. The oils based on LC50 were arranged as sunflower oil > sesame oil > castor oil > neem oil > karanj oil > groundnut oil > mustard oil > turmeric leaf oil. The oils based on toxicity were arranged as turmeric leaf oil > mustard oil > groundnut oil > karanj oil > neem oil > castor oil > sesame oil > sunflower oil. The oils based on oviposition inhibition were arranged as turmeric leaf oil > karanj oil > sunflower oil > neem oil > groundnut oil > castor oil > mustard oil > sesame oil. The data of age and stage specific life table will be useful for efficient management of C. chinensis on mung bean as it gives precise time of infestation. The data of toxicity could be utilized for different degree of infestation caused by C. chinensis on pulses.
