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 Soil Properties, and Yield and Quality of Indian Mustard (Brassica juncea L.)
    (Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), 2017) Chandan, Shivendu Kumar; Singh, Sanjay Kumar
    A field experiment was conducted on sandy loam soil during during winter (Rabi) season 2015-16 at research farm of Tirhut College of Agriculture, Dholi, Muzaffarpur a campus of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar under Randomized Block Design (RBD) with 11 treatments on Indian mustard variety (Rajendra suphlam) to study the “Effect of Integrated Nutrient Management on Soil Properties, and Yield and Quality of Indian Mustard (Brassica juncea L.)”. The soil of the experimental field was calcareous in nature with pH 8.56, EC 0.43 (dSm-1), Organic carbon 0.56 (%) indicates moderately fertile. The available nitrogen (162.0kg ha-1), available phosphorus (8.68kg ha-1), available potassium (96.40kg ha-1) and available sulphur (10.86kg ha-1) was also observed medium in range. Integrated use of organic and inorganic fertilizers along with microbial inoculants was showed initially non- significant differences on plant height at 30 DAS and increased slowly up to the 30 days of sowing growth variation was not observed remarkable with any of the treatments irrespective of its sources. Plant height at 60 DAS was affected significantly with addition of different treatments and it was ranged from 79.83 to 108.17cm and showed marked differences on plant height at 90 DAS for each of the treatment combinations over control. The maximum fresh (10.43g) and dry weight (1.26g) of plant was observed at 30 DAS with application of 100%RDF+S@40kg ha-1+Vermicompost @5t ha-1+Azotobacter+PSB (T4). The effect of integrated nutrient management on length of siliqua was not observed significant whereas, the number of siliqua plant-1 was significantly influenced by the application of different combinations of organic and chemical fertilizers along with bio-fertilizers. Application of 25% reduced quantity of RDF in combination with organics and bio-fertilizers, increased no. of seeds siliqua-1 significantly and it amounted 21.27 percentage over control. In case of no. of seeds siliqua-1, the maximum (12.44) was recorded in 75%RDF+S@40kg ha-1+Vermicompost @ 5t ha-1+Azotobacter+PSB which was 15.51% more than 100% RDF+S @40k ha-1. The test weight significantly increased by 19.25% was observed in the treatment where applied 100% RDF+S@40 kg ha-1+Poultry manure @2t ha-1+Azotobacter+PSB irrespective of other sources. Grain yield of mustard was ranged between 866.80 to 1782.24 in different treatments and the yield was obtained 106% more over absolute control in 75%RDF+ S@40 kg ha-1+Vermicompost @5t ha-1+Azotobacter+PSB. The leaf area index was ranged from 1.86 to 2.44 and maximum LAI value (2.44) was recorded in treatment T9 where applied 75%RDF+S@40kg ha-1+Vermicompost @5t ha-1+Azotobacter+PSB. The higher quantity of nitrogen utilization in seed (41.70 kg ha-1) and stover (33.18 kg ha-1) was found in T9 where, incorporated 75%RDF+S@40kg ha-1+Vermicompost @5t ha-1+Azotobacter+PSB, whereas, the percentage increased of P uptake in seed and stover (48.58%) and (36.21%) was associated with 75%RDF+S@40kg ha-1+Vermicompost @5t ha-1+Azotobacter+PSB over 100%RDF and 75%RDF. Maximum potassium and sulphur uptake in seed and stover (15.15 & 91.64 kg ha-1) and (13.37 & 19.81 kg ha-1) was noticed in T9 and T6 respectively. Percentage increased of organic carbon between 16.07 to 35.72 % was quantified in different treatment combinations over control. However, the changing in soil pH and electrical was observed little with different treatments. Reduced bulk density 1.28 Mg m-3 was reported with application with T9 (75%RDF+S@40kg ha-1+Vermicompost @5t ha-1+Azotobacter+PSB). Water holding capacity (40.61%) was recorded in T9 (75%RDF+S@40kg ha-1+Vermicompost @5t ha-1+Azotobacter+PSB) which is increased with the addition of organics. The maximum available nitrogen (200.4kg ha-1) and phosphorus (14.1kg ha-1) content was recorded in T9 and T4 respectively. Under the different treatments, maximum available potassium (117.24 kg ha-1) was recorded at T4 (100% RDF+S@40kg ha-1+Vermicompost @5t ha-1+Azotobacter+PSB) followed by RDF+S@40kg ha-1+Poultry manure @2t ha-1+Azotobacter+PSB. Free fatty acid and acid value (%) of mustard oil was ranged from 1.28 to 1.59% & 2.56 to 3.17% in different treatment combinations. The minimum value of free fatty acid (1.28%) was observed in T5 (RDF+S @40 kg ha-1 +Poultry manure @2t ha-1) which indicate generally good quality of oil of health point of view. High linoleic acid (18.81%) was noticed in T10 and linolenic acid content was found in mustard oil ranged between 10.17 to 13.18%. The highest SFA: PUFA ratio in mustard from the present investigation was obtained in T7 while, SFA: MUFA highest ratio was noticed in T5. The treatment T9 recoded highest gross return due the higher yield of mustard seed obtained at applied 75%RDF+ S@40 kg ha-1+Vermicompost @5t ha-1+Azotobacter+PSB. Best B:C ratio 2.22 & 2.26 were obtained from T2 & T7 where, applied with 100%RDF and 75% RDF fertility.
