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.

    Population dynamics and management of pod borer (Etiella zinckenella Treit.) and aphid (Aphis craccivora) on lentil (Lens culinaris L.)

    Population dynamics and management of aphid (Aphis craccivora) and pod borer (Etiella zinckenella) was studied at Research Farm Tirhut College of Agriculture Dholi, (Muzaffarpur) during Rabi, 2017-18. Lentil variety HUL-57 was selected for experimentation. The incidence of aphid started from 4th standard meteorological week (SMW) (23.80 aphid/plant/10 cm apical twigs). The aphid population gradually increased and reached to its peak (35.40 aphid/plant/10cm apical twigs) on 7th SMW (22nd February) and thereafter its population gradually decreased. The aphid population had significant negative correlation with minimum temperature and maximum temperature (r = -0.613, r = -0.671). Relative humidity at 7 and 14 hrs had non significant positive correlation. The incidence of pod borer was observed from 7th SMW (4.0%) and the per cent pod damaged gradually increased and reached to its peak (14.30 %) on 9th standard meteorological week. Its infestation gradually decreased from 10th standard week (12.10%). The per cent pod damage had positively significant correlation with minimum temperature (r = 0.582) while maximum temperature and 7 hrs relative humidity showed non-significant positive correlation. All the screened genotypes differed significantly in respect of mean number of aphid/plant at 50% flowering stage. Among the genotypes, PL 4, VL 148, VL 126, LL 1320, PL 406, NDL 14-12, LL 1370, PL 063 and LL 1397 were found statistically at par with check variety HUL 57. However, at 50 % podding stage PL 4, VL 148, VL 126, PL 406 and LL 1397 were found to be statistically at par with check variety HUL 57. None of the genotypes screened was found superior to check variety. The lowest pod damage (7.8 %) by pod borer was recorded with the genotype VL 148 which was statistically at par with LL 1320 (8.0 %) and NDL 14-12 (9.4 %) and significantly superior over check HUL 57 (12.8 %). Genotype VL 148 was recorded as the least susceptible genotype (-64.1 % susceptibility) followed by LL 1320 (-60.0 % susceptibility), NDL 14-12 (-36.2 % susceptibility) and VL 126 (-23.1 % susceptibility). Genotype L 4751 was found as the most susceptible genotype. All the insecticidal treatments were significantly superior to control in reducing the aphid population. It varied from a minimum of 6.3 aphid / plant to the maximum of 33.9 aphid / plant in control. The per cent reduction in aphid population over control ranged from 65.8 to 81.5 per cent. Among treatments, foliar application of profenophos (50 EC) was found to be most effective in reducing aphid population and was at par with flubendiamide (39.4 EC) and fipronil (5% SC) treatments. All the treatments were also found significantly superior over control in minimizing mean per cent pod damage. The lowest mean per cent pod damage (2.0 %) was recorded by the application of profenophos (50 EC) as against 14.0 per cent in untreated control. The per cent reduction in pod damage over control was maximum (85.8 %) by the application of profenophos 50 EC followed by flubendiamide 39.4 EC which was at par with fipronil 5% SC whereas minimum by the application of novaluron 10 EC. Maximum grain yield (15.6 q / ha) was recorded with foliar application of profenophos (50 EC) which was statistically at par with flubendiamide 39.4 EC (14.7 q /ha), fipronil 5 % EC (13.8 q /ha) and imidacloprid 17.8 SL (13.3 q/ha) applied at their test doses. Maximum net profit was obtained with profenophos 50 EC followed by flubendiamide 39.4 EC and fipronil 5% SC (Rs 17999, 14350 and 10411 / ha, respectively). Profenophos 50 EC treatment recorded maximum benefit cost ratio of 9.47:1 closely followed by flubendiamide 39.4 EC with benefit cost ratio of 7.21:1.
