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.

    Integrated weed management in sunflower (Helianthus annus L.)
    (Rajendra Agricultural University, Pusa (Samastipur), 2015) Hans, Hansraj; Bharati, Vikram
    A field experiment entitled “Integrated weed management in sunflower (Helianthus annus L.)” was carried out during spring 2014 at the Research Farm of Tirhut College of Agriculture, Dholi, R.A.U., Pusa, Bihar, India to investigate the effect of manual, herbicidal and integrated treatments on the weed dynamics, growth, yield and economics of sunflower. The experiment was laid out in randomized block design with three replications. Treatments constituted viz., pendimethalin @ 0.75 kg a.i./ha (38.7 CS new molecule) as pre-emergence, pendimethalin (38.7 CS new molecule) @ 0.75 kg a.i./ha as pre-emergence + one intercultivation at 20 DAS followed by hand weeding at 40 DAS, pendimethalin (38.7 CS new molecule) @ 1.0 kg a.i./ha as pre-emergence + quizalofop ethyl @ 37.5 g a.i./ha at 20 DAS, pendimethalin (38.7 CS new molecule) @ 1.0 kg a.i./ha as pre-emergence + propaquizafop @ 62 g a.i./ha at 20 DAS, pendimethalin (38.7 CS new molecule) @ 1.0 kg a.i./ha as pre-emergence + fenoxoprop ethyl @ 37.5 g a.i./ha at 20 DAS, farmers practice (one hand weeding at 30 DAS), pendimethalin (38.7 CS new molecule) @ 1.0 kg a.i./ha as pre-emergence + one weeding by power weeder at 35 DAS, one weeding by power weeder at 35 DAS, weed free (two hand weeding at 20 and 40 DAS) and unweeded control. Weed management treatments significantly influenced growth parameters, quality parameters, yield attributes and yield of sunflower. Plant height (cm), head diameter (cm), 100 seed weight (g), seed yield (q/ha), straw yield (q/ha) obtained under weed free (twice hand weeding at 20 and 40 DAS) had significantly higher value than pendimethalin (38.7 CS new molecule) @ 0.75 kg a.i./ha as pre-emergence + one intercultivation at 20 DAS followed by hand weeding at 40 DAS, pendimethalin (38.7 CS new molecule) @ 1.0 kg a.i./ha as pre-emergence + propaquizafop @ 62 g a.i./ha at 20 DAS, pendimethalin (38.7 CS new molecule) @1.0 kg a.i./ha as pre-emergence + quizalofop ethyl @ 37.5 g a.i./ha at 20 DAS. Hand weeding twice at 20 and 40 DAS though recorded higher seed yield and straw yield but statically at par with pendimethalin (38.7 CS new molecule) @ 0.75 kg a.i./ha as pre-emergence + one intercultivation at 20 DAS followed by hand weeding at 40 DAS and pendimethalin (38.7 CS new molecule) @ 1.0 kg a.i./ha as pre-emergence + propaquizafop @ 62 g a.i./ha at 20 DAS. Prominent weeds found in the experimental plot were Cynodon dactylon, Cyperus rotundus, Chenopodium album, Parthenium hysterophorus and Cannabis sativa. Among the herbicides tested, the highest weed control efficiency (%) recorded under weed free (twice hand weeding at 20 and 40 DAS) and was followed by pendimethalin (38.7 CS new molecule) @ 0.75 kg a.i./ha as pre-emergence + one intercultivation at 20 DAS followed by hand weeding at 40 DAS. The lowest weed index (%) was noticed under pendimethalin (38.7 CS new molecule) @ 0.75 kg a.i./ha as pre-emergence + one intercultivation at 20 DAS followed by hand weeding at 40 DAS. The higher gross return 86,533.00 (`/ha) was obtained under weed free (twice hand weeding at 20 and 40 DAS) and was at par with pendimethalin (38.7 CS new molecule) @ 0.75 kg a.i./ha as pre-emergence + one intercultivation at 20 DAS followed by hand weeding at 40 DAS, however the highest net return 55,233.31 (`/ha) and benefit: cost ratio (1.93) were fetched under under the treatment pendimethalin (38.7 CS new molecule) @ 1.0 kg a.i./ha as pre-emergence + propaquizafop @ 62 g a.i./ha at 20 DAS.
