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.

    Seasonal incidence, biology and management of Ocimum leaf folder, Orphanostigma abruptalis (Walker) on sweet basil (Ocimum basilicum Linn.) through botanical insecticides
    (DRPCAU, PUSA, 2022) Kumar, Amit; Kumar, Manoj
    The present investigation entitled “Seasonal incidence, biology and management of Ocimum leaf folder, Orphanostigma abruptalis (Walker) on sweet basil (Ocimum basilicum Linn.) through botanical insecticides” was studied in Kharif 2021 in the field of Herbal Garden, Hi-tech unit and laboratory of Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur) Bihar. In the course of research, the study of seasonal incidence of ocimum leaf folder, O. abruptalis on sweet basil revealed that the larval population exhibited significant a non- significant relationship with Standard Meteorological Week (SMW). The incidence of ocimum leaf folder were observed from 39th SMW which was (2.33 larvae/ 5 plants) while the peak population of this pest was recorded at 47th SMW (11.00 larvae/ 5 plants) afterwards the population of leaf folder started gradually decreasing by maturity of the sweet basil crop. The correlation studies with leaf folder population in relation with weather parameters where larva of ocimum leaf folder were negatively non- significant correlated (-0.14NS) with maximum temperature whereas positively non-significant correlated (0.53NS) with minimum temperature, while positive and non-significant correlation (0.48NS) with morning relative humidity whereas negatively significant correlation (-0.59*) with evening relative humidity and non-significant & negatively correlated (-0.39NS) with rainfall. The studies on biology of ocimum leaf folder were conducted in ambient conditions. The incubation period of eggs was 3-6 ((mean 4.0±0.89) days. The larva goes through five instars (four moultings) to complete its larval period. A full matured caterpillar was 16.80 mm long and body width was 2.03 mm. and total larval period was completed within 9-14 (mean 10.4 ±1.72) days. The adult male lasts for 7-9 days while female moth remains for 9-12 days. The total life cycle of this pest was completed within 25-36 (mean 30.2± 3.54) days. The observations on botanical insecticides efficiency of different treatments on mean larval population of ocimum leaf folder the treatment Azadirachtin 1.5 % @ 0.75 litre/ha was observed highly effective treatment which counted leaf mean larval population (4.44/ 5 plants) followed by the succeed productive treatment was neem oil 2 % @ 10 litre/ha was observed the mean population (4.87/5 plants). This was found statistically at par with NSKE 5 % @ 25 kg/ ha recorded (5.09 larva/ 5 plants) followed by karanj oil 2 % @ 10 litre /ha which was recorded (5.51 larva/5 plants) and castor oil 2 % @ 10 litre /ha (5.57 larva/ 5 plants)> tobacco decoction 5 % @ 25 kg/ha (5.74 larva/5 plants) which was better than control plot (8.14 larva/5 plants).

    Adoption behaviour of jute growers in Kosi region of Bihar
    (Dr. Rajendra Prasad Central Agricutural University, Pusa, Samastipur, 2019) Kumar, Amit; Ansari, Naushad
    The study entitled “Adoption Behaviour of Jute Growers in KosiRegion of Bihar” was conducted with the specific objectives to know the socio-economic conditions, their level of knowledge and extent of adoption about jute cultivation practices along with the association between selected independent variables. Attempts were also made to identify the constraints faced by the jute growers and to explore the suggestions given by them to overcome the constraints and various problems occurring in jute cultivation. The present study was carried out in Kosi region of Bihar. Three district namely Madhepura, Saharsa and Supaul were selected for the study, from these three districts one block from each district were selected on the basis of major area under jute cultivation.And from each block two villages were selected randomly, further fifteen respondents were selected from each villages constituting a total sample size of 90 jute growers for the study purposes. Face to face interaction with the help of well prepared interview schedule was used for collection of data. The collected data were analyzed with the help of frequency distribution, mean, standard deviation and Pearson‟s correlation coefficient. The study revealed that majority of the jute growers of Kosi region were belonged to middle age group, having primary/middle school level of education, maximum percentage of them belonged to backward class and having marginal land holding area. It was also indicated that majority of them having medium level of their annual income from all available sources,they were medium in contact with different extension agencies, their exposure to mass media tools were medium to high. They were also medium in orientation towards scientific cultivation, economic orientation and also in risk bearing ability. The findings also indicated that, they weremedium in level of knowledge and extent of adoption of jute production technology.The study also revealed that out of ten independent variables, eight variables i.e. education, land holding, annual income, extension contact, mass media exposure, scientific orientation, economic orientation and risk orientation shows positive significant relationship with the knowledge level and extent of adoption of jute growers towards jute cultivation practices. Age shows negative correlation with knowledge level and adoption of jute growers and caste shows non-significant relationship with the level of knowledge and adoption. It is concluded that the major constraints faced by the jute growers in Kosi region of Bihar were lack of mechanization for processing of jute after harvest, lack of proper storage house, appearance of different types of insect, pest and diseases, intensity of flood and drought, lack of proper marketing channel, unaware of the practice of seed treatment, lack of technical knowledge with respect to use of pesticides, lack of assured and adequate irrigation facility and poor drainage system and lack of extension service. The important suggestion given by jute growers were develop mechanization for extraction of jute, develop water resources and timely availability of water for retting, establishment of retting tanks, release of flood tolerant varieties, providing good quality seed at cheaper rate, appropriate control measures of pest and diseases, timely technical guidance and soil testing, provision of fertilizers on subsidized rates, supply of effective plant protection chemicals,provision of credit facility, develop proper market structure to overcome the problem by middle manand providing good transport facility .
