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.

    Influence of moisture regimes on system profitability, water productivity and soil health under rice based cropping systems
    (Rajendra Agricultural University, Pusa (Samastipur), 2016) Kumari, Rinki; Nandan, Ravi
    A field experiment was conducted at Research Farm of Rajendra Agricultural University Pusa during 2012-2013 to 2013-2014. The soil of experimental site was Entisol, sandy loam with pH 8.6, low in organic carbon (0.44 %), available N (150.52 kg/ha), available P2O5 (18.33 kg/ha) and medium in available K2O (158.20 kg/ha). The experiment was laid out in split plot design with 15 treatment combinations in three replications. The treatments were 5 cropping sequences in main plots i.e. rice-potato-groundnut, rice-potato-cowpea (green pods), rice-potato-greengram, rice-maize+potato-sesbania (green manure), rice-maize+garden pea (green pods) and 3 moisture regimes in sub-pots i.e. 0.8, 1.0 and 1.2 IW/CPE ratios for rabi and zaid crops. The depth of each irrigation was 6 cm. Rice was grown under system of intensification (SRI) in all the cropping sequences. The rice crop was irrigated at 3 days after disappearance of ponded water (DAD) with 3 cm depth. The total effective rainfall received during 2012-13 and 2013-14 was 61.3 cm and 52.4 cm, respectively. The maximum rice equivalent yield (REY) of 281.12 q/ha was recorded under rice-maize+potato-sesbania (green manure) cropping sequence however, was statistically at par with rice-potato-groundnut cropping sequence and both were significantly superior over rest of the cropping sequences. Significantly higher REY was registered at 1.2 IW/CPE ratio (256.96 q/ha) as compared to moisture regime of 0.8 IW/CPE ratio but was statistically at par with 1.0 IW/CPE ratio. Maximum production efficiency (PE) of 88.08 kg/ha/day was recorded with rice-potato-groundnut sequence which was found significantly superior over other cropping sequences except to that of rice-maize+potato-sesbania (green manure) cropping sequence (83.42 kg/ha/day). Maximum PE of 82.67 kg/ha/day was noticed at 0.8 IW/CPE ratio which was comparable with 1.0 IW/CPE ratio (80.26 kg/ha/day) but was significantly superior over 1.2 IW/CPE ratio. Rice-maize+potato-sesbania (green manure) cropping sequence occupied the field for longer period with land use efficiency (LUE) of 92.32 per cent while moisture regimes did not influence the LUE. Water-use efficiency (WUE) and water productivity were exhibited the highest value in rice-maize+potato-sesbania (green manure) cropping sequence (229.64 kg/ha-cm and ` 18.84/m3, respectively). No significant differences in WUE and water productivity were observed due to different moisture regimes. Rice-maize+potato-sesbania (green manure) cropping sequence generated maximum gross returns (` 366915/ha) and net returns (` 230300/ha) while rice-maize+garden pea cropping sequence showed the highest B: C ratio (3.05) however, under different moisture regimes the highest gross returns (` 335724/ha), net returns (` 214530/ha) and B: C ratio (1.87) were recorded at 1.2 IW/CPE ratio. Rice-maize+potato-sesbania (green manure) cropping sequence recorded significantly highest total uptake of N (371.63 kg/ha), P (93.70 kg/ha), K (330.74 kg/ha) while the lowest was due to rice-potato-greengram cropping sequence under different moisture regimes. IW/CPE ratio of 1.2 recorded the highest total NPK uptake of 342.05, 74.63, 259.71 kg/ha and the lowest uptake was recorded with 0.8 IW/CPE ratio. There was non-significant variation in pH and EC in all the cropping sequences and moisture regimes. Organic carbon in soil was found significantly highest in rice-maize+potato-sesbania (green manure) cropping sequence (0.56 %) and at moisture regimes of 0.8 IW/CPE ratio (0.52 %). Rice-maize+potato-sesbania (green manure) cropping sequence and moisture regimes at 0.8 IW/CPE ratio registered maximum available N, P2O5, K2O (272.32, 35.24, 187.56 kg/ha, respectively) and (195.86, 30.87, 185.73 kg/ha) respectively as compared to other treatments at the end of second year of investigation.
