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.

    Yield forecasting of sugarcane in Bihar based on biometrical characters
    (Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur (Bihar), 2019) M, Muhammed Irshad; Kumar, Mahesh
    The present study deals with the development of yield forecast models for sugarcane (Saccharum officianarum) in Bihar based on Biometrical characters. For this research observations on plant biometrical characters such as number of millable canes per 100 m2 (X1), average plant height in cm (X2), average cane girth in cm (X3), average length of third leaves cm (X4), average width of third leaves in cm (X5), average cane perimeter in cm (X6), single cane weight in kg (X7), average plant population per 100 m2(X8), number of irrigations in entire crop season(X9), average number of tillers per 100 m2(X10), application of nitrogen (N) in kg/ha (X11), application of phosphorus (P2O5) in kg/ha (X12), application of potassium (K2O) in kg/ha (X13), disease infestation in percentage (X14) and average plant condition (X15) according to eye estimate, were recorded from 50 farmers fields in which 30 farmers were selected from Samastipur, 10 farmers were selected from West Champaran and 10 farmers were from East Champaran districts of Bihar. Simple random sampling was used for selecting farmer‟s field. All possible regression analyses were carried out to select the best combination of variables on the basis of some important statistics such as, RMSE, CV, R2 and adj- R2 . ̂ -596.51888+ 1. 35081X1-0.84646X2+ 1.08494X4 + 32.1379X5 + 423.25714X7- 6.40145X9 + 0.79303X13-13.20593X15 CV= 4.525, R2 = 0.9385, Adj R2=0.9248, RMSE = 32.269, Standard Error residuals=23.444 Further assessment regarding accuracy of model has been done on comparing the actual yield from 10 % of the observations not included in the model development with their predicted value and results shows close resemblance with the margin of error ranging from (5.91-8.36%). Forecasted yield of sugarcane has been worked out as 847.82 q/ha in Bihar with the help of proposed model. Forewarning models for wilt disease on sugarcane based on climate factors was mainly aimed at to study the behavior of climate factors on wilt of sugarcane, to establish association between climatic factors and wilt diseases of sugarcane in different years in sugarcane growing seasons, to generate forewarning statistical models for prediction of wilt diseases based on climatic factors. Data collection was done on the basis of major sugarcane grown area and also compatibility. The secondary data on wilt incidence (%) of sugarcane along with climate factors were collected for the period from 2008 to 2017 during crop seasons. The climatic factors from 2008 to 20117 in sugarcane growing seasons, the average rainfall distribution varied greatly within sugarcane growing seasons over years (19.5 mm – 78.5 mm). The average minimum temperatures (18.70C – 260C), maximum temperature (300C -310C), morning relative humidity (83.7-87.6%) and evening relative humidity (51.8-85.8%) were observed. Correlation studies revealed that there was positive association between the wilt infestation and weather factors morning relative humidity (0.23) while significant positive correlation with minimum temperature (0.89) and negative association with evening relative humidity (-0.03) while significant positive correlation was showed with maximum rainfall (0.97), maximum temperature (0.629). The Multiple Linear Regression (MLR) model was developed with respect to these factors with R2= 0.969. The MLR models for between years found to be useful in the prediction of wilt incidence of sugarcane. (Ŷ) = -99.498+0.142X1+0.345X2+0.601X3-0.05X4+0.46X5+6.252X6 Data was collected using structured schedule and procedure for quantifying Socio-economic status of sugarcane farmers. The data revealed that more than half of the respondents (52%) were small landholders, respondents had high school and above (86%) education, Majority (78%) of the respondents were belonged to UR category, majority (66%) of the farmers had joint family (less than five Members) and Cent percent of the respondents were following agriculture as their main Occupation. There is a positive correlation between income of the farmer with land holding and education Validation of selected forecasting model (5th model) was done by using forecast error (FE), mean absolute error (MAE), Mean absolute percentage error (MAPE),and mean square error (MSE). All the parameters shows a minimum value for the model 5 Key Word: Pre harvest forecast of sugarcane yield, Biometrical Characters of sugarcane, Farmers appraisal, forewarning of disease, socioeconomic condition of the farmer.
