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.

    Population dynamics and management of major sucking insect pests of cowpea (Vigna unguiculata Linn.)
    (RPCAU, Pusa, 2023) DEVI, DHARANIKOTA LALITHAMBICA; Sunil Kumar Mandal
    The present investigation entitled “Population dynamics and management of major sucking insect pests of cowpea (Vigna unguiculata Linn.)” was conducted during 2023 cropping season at Vegetable Research Farm, RPCAU, Pusa, Bihar. The study focused on survey of major insect pests of cowpea in Samastipur, Bihar to investigate the incidence of insect pests affecting cowpea. Field observations were carried out at three blocks in Samastipur district during the entire growth period of crop. The major findings acknowledged were sucking pests like aphids (19.89/10 cm twig) observed maximum in Kalyanpur block whereas whiteflies (4.83/ 3 leaves/ plant) and leafhoppers (2.82/3 leaves/plant) in Samastipur block and thrips (8.44/ 5flower buds/plant) in Pusa block. The population of pod sucking bug (5.58/plant) was highest in Samastipur block and maximum pod damage (21.26 damaged pods/100 pods) was recorded in Pusa block. The findings on population dynamics of major sucking insect pests of cowpea revealed that aphid, leafhopper and whitefly population were commenced first on 4th week of March (12th SMW) and reached its peak of 22.80 aphids/ 10 cm twig, 8.17 leafhoppers/3 leaves /plant and 11.20 whiteflies/ three leaves/plant on 3rd week of April (16th SMW). Population of thrips was commenced on 5th week of March (14th SMW) and maximum population was noted during 3rd week of April (16th SMW). The population of aphid, leafhopper, whitefly and thrips showed positive and significant correlation with maximum temperature and negative significance with relative humidity. The bioefficacy of various newer insecticides were also evaluated against sucking insect pests of cowpea. Among them, Thiamethoxam 25% WDG proved most effective causing maximum population reduction of major sucking insect pests viz., aphids, leafhopper, whitefly, and thrips followed by Imidacloprid 17.8% SL. Diafenthiuron 50% EC, Acetamiprid 20% SP, Buprofezin 25% SC, Fipronil 5% SC stood in middle order of efficacy and Dimethoate 30% EC (Standard check) had least efficacy. The maximum yield 97.26 q/ha was obtained in the plots treated with Thiamathoxam 25% WDG followed by Imidacloprid 17.8% SL (92.13 q/ha). The minimum yield of 81.10 q/ha was obtained in the plots treated with Dimethoate 30% EC (standard check).
