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.

    Response of mustard [Brassica juncea (L.) Czern and Coss] to moisture stress and its amelioration by microbes
    (DRPCAU, Pusa, 2021) Mohan, Krishna; Kavita
    Mustard [Brassica juncea (L.) Czern and Coss] is an important oilseed crop belonging to family Brassicaceae (Syn. Cruciferae) which is sensitive to moisture and is adversely affected by moisture stress in terms of growth and yield. Inoculation of plants with microbes such as Trichoderma viride and Bacillus subtilis can enhance plant growth under moisture stress conditions, which is an eco-friendly approach to sustainable agriculture. The present investigation entitled “Response of mustard [Brassica juncea (L.) Czern and Coss] to moisture stress and its amelioration by microbes.” was conducted with two objectives viz., to identify contrasting set of mustard genotypes against moisture stress and to study the response of microbes on morpho-physiological and biochemical traits in contrasting mustard genotypes under moisture stress. For the identification of contrasting set of mustard genotypes to moisture stress, experiment was performed in Petri dishes with 30 genotypes of mustard viz., NPJ 214, LES 54, NPJ 210, NPJ 210, RB 100, 81J0117, RGN-444, DRMRHJ1118 (Hybrid), DRMRCI 95, NPJ-225, RH 1424, RH 1584, PM-29, PM-30, RB-102, TM 179, PDZ 9, RH 1555, NPJ 211, LES 57, NPJ 212, NPJ 216, RLC 7, DRMR 541-44, DRMRCI 114, RGN 229, DRMR CI70, Kranti, RGN 73, RCH 1## and RLC 3#. All the genotypes were subjected to control (0.0 MPa) and moisture stress (-0.6 MPa and -0.8 MPa) for 7 days and germination percent, seedling length, shoot dry weight, root dry weight, vigour index-І and vigour index-II were recorded. Results showed that mustard genotypes on exposure to different moisture stress levels (-0.6 and -0.8 MPa) experienced significant reduction in germination per cent and seedling growth parameters (seedling length, dry weight of shoot and root and vigour index) over control. At maximum moisture stress i.e. -0.8 MPa, genotype NPJ-214 had the minimum reduction while TM-179 showed the maximum reduction in these parameters and hence rated as relatively tolerant and susceptible genotypes, respectively. These two genotypes were further used to study the response of microbes on morpho-physiological and biochemical traits Plant height, relative water content, membrane stability index, total chlorophyll content and leaf area remarkably decreased due to moisture stress and conversely increased in all the microbial treatments over control (without microbial inoculation), whereas lipid peroxidation, proline, antioxidative enzymes viz. catalase and peroxidase were remarkably increased due to moisture stress but decreased by microbial application. On the basis of present study it was concluded that, moisture stress adversely affected morpho-physiological and biochemical attributes of mustard genotypes. These parameters were best improved under control as well as moisture stress with the soil application of Trichoderma viride at 35 DAS. Hence, this treatment can be used in ameliorating moisture stress.
