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.

    EVALUATION OF POSTHARVEST QUALITY OF MANGO GENOTYPES DURING STORAGE
    (DRPCAU, PUSA, 2022) SAROJ, NEETU; Prasad, K.
    The present experiment entitled ‘‘Evaluation of postharvest quality of mango genotypes during storage’’ was undertaken on 30 mango genotypes. Since most of the indigenous mango genotypes grown in northern Bihar and newly released hybrids in India have not been assessed for nutritional profiling and postharvest quality attributes. Hence, this study was conducted with two objectives. Under objective-I there were two experiments, experiment-I, was conducted for assessment of 30 genotypes towards physical (fruit firmness), physiological, biochemical, sensory evaluation, and enzymatic activity changes at ambient storage condition (25 ± 4 ℃, 65 ± 5 % RH). Under the experiment-II the selected genotypes were assessed for physical, physiological, quality, functional and determination of mineral contents at peak ripening stage. Under the objective-II the selected genotypes were assessed for suitability of pickle and squash making. Under experiment-I of first objective, among studied attributes, PLW was the highest in ‘Chausa’ (19.0 %), fruit firmness was the highest in ‘Sipiya’ (11.97 N).The highest respiration rate was exhibited by ‘Chausa’ (109.10 ml CO2 kg-1 h-1), TSS was the highest in Amrapali (21.6 %), highest titratable acidity was recorded in ‘Suvarnarekha’ (0.40%).The highest ascorbic acid content (46.88 mg/ 100g), Name of student : NEETU SAROJ Registration Number : M/HORT.(FS)/492/2020-21 Major advisor : Dr. K. Prasad Degree to be awarded : Master of Science in Agriculture Major subject : Horticulture (Fruit Science) Minor subject : Genetics and Plant Breeding Year : 2022 Title of thesis : “Evaluation of postharvest quality of mango genotypes during storage” University : Dr. Rajendra Prasad Central Agricultural University Pusa (Samastipur), Bihar -848125 Total pages of thesis : 89 + (i-x) Bibliography antioxidant activity (4.836 μmol TE/g) and the total flavonoid (682.40 μg/g) was recorded highest in ‘Sukul’, highest total carotenoid content was recorded in ‘Amrapali’ (7.38 mg/100g, total phenolic content was the highest in ‘Malda’ (512.48 μg GAE g-1 FW). Irrespective of storage, the overall acceptability value was the highest in ‘Malda’ (8.6). Among the enzymatic activities, polygalactouronase (PG) activity (35.78 μg galactouronic acid g-1 h-1 FW), pectin methylesterase (PME) activity (0.260 μmol min-1 g-1 FW) and lipoxygenase enzymatic activity (LOX) (5.486 μmol g-1 FW min-1) was the highest in ‘Chausa’. Under experiment- II of first objective, our results revealed that the selected genotypes varied significantly for the studied attributes at peak ripening stage. Under physical attributes, maximum fruit weight was found in ‘Fazli’ (404.66 g). The peel thickness was the maximum in ‘Sukul’ (1.89 mm), fruit firmness was the highest in ‘Sipiya’ (12.75 N), seed weight was the maximum in Fazli (27.23 g), higher shelf life was exhibited by genotypes such as ‘Sukul’, ‘Sipiya’, ‘Amrapali’, ‘Malda’ and ‘Safed Malda’. Under physiological attributes, respiration rate was the highest in ‘Chausa’ (137.19 ml CO2 kg-1 h-1). Among quality, functional attributes and determination of mineral contents, the TSS was the maximum in ‘Amrapali’ (25.2%), total sugars were highest in ‘Mallika’ (20.12 %), titratable acidity was the maximum in ‘Malda’ (0.37%), ascorbic acid content was the maximum in ‘Sukul’ (45.5 mg/100g pulp) total antioxidant was observed highest in ‘Sukul’ (6.32 μmol TE/g), total carotenoids content was the maximum in ‘Amrapali’ (9.1 mg/100g), total phenolic content was the maximum in ‘Malda’ (560.6 μg/100g), total flavonoids content was the maximum in ‘Sukul’ (720 μg/100g). Maximum phosphorous content was found in ‘Sukul’ (1.79 mg/kg) and the potassium content was the maximum in ‘Malda’ (12.64 mg/kg). Under objective-II genotypes such as ‘Malda’ (8.8), ‘Safed Malda’ (8.6), ‘Chausa’ (8.7), ‘Kalkatiya Malda’ (8.5) and ‘Alphonso’ (8.5) showed highest sensory score for sweet pickle whereas ‘Sukul’ (8.8), ‘Sipiya’ (8.4), ‘Langra’ (8.4), ‘Bathua’ (8.3) and ‘Krishna Bhog’ (8.3) exhibited highest sensory score for salted pickle. Among selected genotypes ‘Malda’ (8.8), ‘Safed Malda’ (8.6), ‘Kalkatiya Malda’ (8.6), ‘Fazli’ (8,7) and ‘Chausa’ (8.7) exhibited highest sensory score for ripe mango squash while Sukul’ (8.8), ‘Sipiya’ (8.5), ‘Bathua’ (8.4), ‘Langra’ (8.2), ‘Amrapali’ (8.2) and ‘Fazli’ (8.5) showed highest sensory score for green mango squash.
