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.

    Long-term effects of organics and inorganic fertilizers on the distribution, transformation and nutrition of sulphur, zinc and boron in calcareous soil
    (Rajendra Agricultural University, 2012) Pandey, Amit Kumar; Prasad, J.
    A long-term field experiment was started during rabi 1988-89 in calcareous soil at RAU, Pusa Farm in split plot design with NPK levels in main plots and organic sources in sub-plots. Rice and wheat as 35th and 36th crop were grown for present investigation. Besides yield of crops and uptake of nutrients, post harvest soil samples were analysed for general properties like bulk density, per cent pore space, water holding capacity, organic carbon, pH, EC, CEC, free CaCo3 available, N, P2O5, K2O, S, Zn and B. Soil samples were also collected from six different depths for distribution analysis of S, Zn and B. Post harvest soil samples were also fractionated for different pools of S, Zn and B. The grain and straw yield of rice and wheat increased significantly with increasing levels of NPK fertilizer. However, the yield at 150 per cent NPK was at par with 100 per cent NPK. The yield was further increased with the conjoint use of organics in the order : compost + crop residue > compost > crop residue > no manure. The result indicated that compost @ 10 t ha-1 could be substituted with crop residues. Similarly, compost + crop residue could save 50 per cent of the recommended dose of NPK i.e. 60 kg N, 30 kg P2O5 and 20 kg K2O kg ha-1. Integrated effect of chemical fertilizers with organic manure and crop residue also augmented N, P, K, S, Zn and B uptake by crops. There was a build-up in available N, P, K and S and depletion of available Zn and B with conjoint use of chemical fertilizer with organics. Addition of different organic materials (compost/crop residue) increase the organic carbon, porosity, water holding capacity, cation exchange capacity and decreased bulk density, pH and EC. Irrespective of NPK levels and organic addition, there was an increase in the mean available sulphur with increasing depth upto 45-60 cm beyond which the values were continuously decreased. The available Zn and B content was higher in surface layer and it progressively decreased along the depth in all the treatments. There was a considerable increase in the population of bacteria, fungi and actinomycetes with continuous application of chemical fertilizers and organic manure alone or in combination. Correlation study indicated that all forms of S, Zn and B were in dynamic equilibrium and positively and significantly correlated with most of the plant parameters. Step down multiple regression equation indicated that difference in plant parameter due to various treatment could well be explained through variation in sulphate S followed by distilled water soluble-S; Zn-bound to crystalline oxide followed by Zn-bound to carbonate and amorphous oxide and oxide bound B followed by readily soluble B. The results of path analysis confirmed the direct effect of sulphate-S, Zn-bound to crystalline oxide and oxide bound-B on crop production and nutrition.

    Sorption and availability of zinc in Diaralands of Bihar
    (Rajendra Agricultural University, 2010) Kumari, Madhavi; Yadav, K.
    The present investigation on “Sorption and availability of zinc in Diaralands of Bihar” was conducted to elucidate the relative influence of soil properties on available zinc, critical limit of zinc in soil and plant, distribution of zinc fraction in soil, zinc adsorption, kinetic of adsorption and desorption and solubility relationship of zinc in diaraland soils of Bihar under laboratory and pot condition. One hundred twenty six cultivated soils of low, medium and upland physiography were collected for zinc delineation. Based on available zinc and organic carbon content 24 bulk soil samples were collected for evaluation of critical limit taking maize as test crop. Out of these 24 soils, 10 soils were selected for adsorption, kinetics of adsorption, desorption and solubility relationship of zinc. Soils were neutral to slightly alkaline in reaction having 78 per cent deficiency in available Zn. The extent of Fe, Mn and Cu deficiency was 30, 11 and 4 per cent respectively. The chemical fractionation of zinc in soil indicated that a very small portion of total zinc was distributed in comparatively more soluble forms and most of the zinc remained as residual fraction. The critical limit of available zinc was 0.75 mg kg-1 whereas the critical concentration of zinc in 45 days old maize plant tissue was 22.5 mg kg-1. The dry matter yield, Zn uptake and zinc concentration in maize plant increased with graded level of zinc. Step down multiple regression analysis and path analysis suggested that water soluble + exchangeable zinc, crystalline oxide bound zinc and amorphous oxide bound zinc are the major pool of soil zinc which contributed towards available zinc, dry matter yield of maize and Zn uptake by maize. Adsorption isotherm studies indicated that most of the soils produced L-type adsorption behaviour whereas a few soils produced S-type of adsorption isotherm. Out of several sorption model tested, freundlich adsorption model was found best fit for adsorption data. Kinetic of Zn adsorption could be best explained through Elovich kinetic model, however, the kinetics of desorption was diffusion controlled. The estimated stability constant is very much close to the theoretical value of Zn-soil but slightly higher than that of Zn (OH)2, hence Zn (OH)2 along with Zn-soil control the solubility of Zn in these soil.
