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.

    Design Modification of Two Row Battery Operated Vegetable Transplanter
    (Dr.RPCAU, Pusa, 2022) KUMAR, NIRANJAN; Sinha, Jaya
    Vegetables are the essential part of diet in India. India is the second largest producer of the vegetables after China. Generally, in India vegetable is transplanted either by traditional manual method which requires high labour cost and high drudgery during transplanting. To reduce the drudgery and manpower requirement in transplanting operation mechanization in vegetable cultivation is needed. The mechanical transplanting of vegetable has been considered the most promising option, as it saves labour, ensures timely transplanting and attains optimum plant density that contributes to high productivity. Keeping this in view, the study was conducted to evaluate the field performance of CAET developed battery operated vegetable transplanter and modification was done as per requirement. The Modified Single Row Battery Operated Vegetable Transplanter (MSRBOVT) had main frame, DC motor, battery, power transmission unit, furrow opener, ski type furrow closing device, seedling delivery tube, seedling holding tray, escalator and motor controller. Field performance of Existing Two Row Battery Operated Vegetable Transplanter (ETRBOVT) and MSRBOVT was done with chilli and brinjal plug seedling. Both transplanter was ergonomically evaluated in terms of physiological cost of operator like subjects heart beat rate and energy expenditure rate during 15 minutes of working. For transplanting chilli and brinjal plug seedling by ETRBOVT at an average speed of 0.192 km/h the average field capacity and field efficiency was observed to be 0.015 ha/h and 86.10%. The transplanting efficiency and survival plant percentage was found 87.61% and 85.78% respectively. Row to row distance, plant to plant distance and depth of transplanting was found to be 0.45 m, 0.45-0.5 m and 0.04 m respectively. The average transplanting rate by existing transplanter was observed to be 692 seedlings per hour. For transplanting chilli and brinjal plug seedling by MSRBOVT at an average speed of 0.289 km/h the average field capacity and field efficiency was observed to be 0.016 ha/h and 92.82%. The transplanting efficiency and survival plant percentage was found to be 88.95% and 86.98% respectively. Row to row distance, plant to plant distance and depth of transplanting was found to be 0.6 m, 0.45-0.5 m and 0.05 m respectively. The average transplanting rate by modified transplanter was calculated 547 seedlings per hour. Average heart beat rate for operating the ETRBOVT for continuous working by Subject A, B, and C was measured to be 113, 136 and 119 beats/min respectively. Average energy expenditure rate for operating the ETRBOVT by Subject A, B, and C was found to be 19.65, 29.18 and 22.14 kJ/min respectively. The work load in operating modified transplanter shifted to “heavy work” to “moderate work” category. Average heart beat rate for operating the MSRBOVT for continuous working by Subject A, B, and C was found to be 100, 119 and 102 beats/min respectively. Average energy expenditure rate for operating the MSRBOVT for continuous working by Subject A, B, and C was found to be 14.11, 22.14 and 15 kJ/min respectively. Cost of operation per hectare with ETRBOVT was Rs.4249.33/ha. Cost of operation per hectare with MSRBOVT was Rs.3673.12/ha. Hence, developed MSRBOVT was better in terms of field performance, physiological cost, work load and economic point of view from ETRBOVT.
