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.

    EFFECT OF INTEGRATED NUTRIENT MANAGEMENT ON PRODUCTIVITY AND QUALITY OF SUGARCANE IN CALCAREOUS SOIL
    (Dr.RPCAU, Pusa, 2022) KUMAR, BRAJESH; Sinha, S.K.
    At Dr. Rajendra Prasad Central Agricultural University in Bihar, a field experiment was carried out to investigate the “Effect of integrated nutrient management on productivity and quality of sugarcane in calcareous soil” during 2021–2022.Vermicompost, green manuring (green gram), fertilizer-NPK (150:85:60) and biofertilizer (Azotobacter and PSB) were used as part of the treatments. The vermicompost was applied at planting and green gram was applied 60 days after planting (DAP). During the spring, sugarcane crop (cv. CoP 112 early) was planted. The germination percent was found non-significant and it varied from 36.5-43.4% and 46.5-55.5% at 45 and 60 days after planting respectively. Compared to strict control and 100% RDF, the combined application of organic, inorganic and biofertilizer produced a much higher number of tillers. The dry matter accumulation at 90,120 and 150 days after planting was found significant while at harvest stage it was found nonsignificant. The number of millable canes varied significantly and ranged from 70.5 × 103 to 125.4 × 103 ha-1. The maximum NMC (Number of millable cane) was obtained in the treatment receiving RDF together with vermicompost and biofertilizer (Azotobacter and PSB). Due to different treatments, the mean cane yield varied significantly and ranged from 41.8 to 94.0 t ha-1. The treatment group receiving RDF coupled with vermicompost and biofertilizer had the highest cane yield, whereas the group receiving absolute control (no fertilizer) had the lowest. Sugar yield is a function of cane yield and followed a similar trend to cane yield. The mean sugar yield varied significantly from 4.5 - 10.5 t ha-1. Brix, pol, purity coefficient and commercial cane sugar was found non-significant. The soil available N (224.33 - 278.92 kg ha-1), available P (22.28 - 36.33 kg ha-1), available K (124.67 - 165.20 kg ha-1) and available S (12.64 - 19.21 mg kg-1) varied significantly due to application of integrated nutrient management in soil. The use of organic and inorganic fertiliser sources over absolute control was also noted as a considerable increase in the Fe, Zn, Cu and Mn content of post-harvest soil. The soil organic carbon stock was found to be non-significant due to the application of nutrients from organic and inorganic fertiliser while the mean soil organic carbon (0.48 - 0.56%), soil microbial biomass carbon (129.10 - 255.90 mg kg-1), and CO2 evolution (36.83 - 60.70 mg 100g-1 soil 24 hr-1) varied significantly. The microflora population in post-harvest soil was significantly higher in treatment receiving RDF along with vermicompost and biofertilizer (Azotobacter and PSB). Due to the impact of various nutrient combinations, the absorption of N (126.97 - 292.58kg ha-1), P (12.54 - 29.96 kg ha-1), and K (114.43 - 271.43kg ha-1) varied significantly. The trend of cane output was similar to the intake of minerals. The effect of various treatment on agronomic use efficiency and physiological use efficiency was varied significantly.
