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.

    Effect of planting density and nutrient management on performance of hybrid maize genotypes under maize-wheat cropping system
    (Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), 2018) Yadav, Shashidhar; Kumar, Mritunjay
    An investigation entitled “Effect of planting density and nutrient management on performance of hybrid maize genotypes under maize-wheat cropping system” was carried out during 2015-16 and 2016-17 at experimental farm of Tirhut College of Agriculture, Dholi (Muzaffarpur), a campus of Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar. The experiment involving genotypes in main plot, density in sub plot and nutrient management in sub-sub plot, was carried out in split-split plot design. Treatments were replicated thrice with maize hybrid genotypes Pioneer 3540 and Rasi 4595, density 50X20 cm and 60X20 cm as well as nutrient management RDF, STCR and SSNM. In rabi, wheat variety K 307was grown in each plot with application of only recommended dose of fertilizer(N,P2O5 and K2O 120,60 and 40 kg/ha) to assess the residual response of maize hybrid genotypes, density and nutrient management. The results revealed that growth parameters like plant height, number of leaves, dry matter accumulation, yield attributes like length of cob, cob weight, number of grains/cob, weight of grains/cob and grain yield (5.38 tons/ha) were found to be maximum under Pioneer 3540 genotype and were significantly superior over (5.05 tons/ha) of Rasi 4595 genotype. Leaf area index, Days to 50% tasselling and silking, number of cobs/plant, girth of cob, test weight and stover yield were not influenced by genotypes of hybrid maize. Gross return, net return and B: C ratio (Rs 103496, 69583/ha and 2.35) respectively, were recorded to be significantly higher in Pioneer 3540 genotype of hybrid maize, which was significantly superior over (Rs 95489, 64705/ha and 2.19) respectively, genotype Rasi 4595. Density influenced significantly on the growth, yield attributes and yield of maize in both the years of maize. Growth parameters like plant height, number of leaves, dry matter accumulation, leaf area index and yield attributes like length of cob, girth of cob, cob weight, number of grains/cob, weight of grains/cob, test weight and grain yield (5.33 tons/ha) were found maximum under 60X20 cm plant density and were significantly superior over (5.10 tons/ha) 50X20 cm plant density.N, P and Kcontent and their uptake were found higher under 60X20 cm plant density,which was significantly superior over 50X20 cm plant density. Significantly higher net return (Rs 68194/ha) and B:C ratio (2.34) were recordedunder 60X20 cm plant density,which was significantly superior over (Rs 66094/ha) and (2.19) under 50X20 cm plant density. Nutrient management had significant effect on the growth, yield attributes and yield of maize in both the years of experimentation. Growth parameters like plant height, dry matter accumulation, leaf area index, yield attributes like length of cob, girth of cob, cob weight, number of grains/cob, weight of grains/cob, test weight and grain yield (5.63 tons/ha) were found maximum under STCR nutrient management and were significantly superior over SSNM as well as N, P and Kcontent and their uptake were found higher under STCR, which was significantly superior over (5.12 tons/ha) SSNM. Significantly higher B:C ratio (2.32) of maize achieved with SSNM, which was statistically at par with (2.26) RDF during both the years of experimentation. The residual effect of genotypes and density did not show significant influence on growth and yield of wheat during both the years of experimentation. Nutrient management had slightly significant effect on the yield of wheat during second year of experimentation. The effect of genotypes and density did not show significant influence on system productivity during both the years of experimentation. Nutrient management had significant effect on the system productivity however, maximum system productivity (10.27 tons/ha) was recorded in STCR.
