University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    (University of Agricultural Sciences GKVK, Bangalore, 40865) ATIQULLAH, SEDIQY; GOPINATH, G
    Golden rod (Solidago canadensis L.) is one of the most favoured flower crops grown for its cut flowers in the world market. It is being used as a filler material in bouquets and vases. Studies were conducted on the post-harvest life of golden rod (Solidago canadensis L.). The present studies involving sucrose solution, metallic salts like aluminium sulphate, cobalt sulphate and silver thiosulphate were used alone or in combination with sucrose and 8-HQS with the main objective of knowing their influence in maintaining the quality and extending the post harvest life of the golden rod cut flowers. The treatments T4 (STS @ 400 ppm + sucrose @ 2 per cent + 8-HQS @ 200 ppm) and T8 (aluminium sulphate @ 1000 ppm + sucrose @ 2 per cent + 8-HQS @ 200 ppm) which were on par with each other registered higher cumulative uptake of water (195.00 and 204.00 g/cut flower, respectively). Similarly, the treatments T1 (tap water) and T2 (distilled water) which were on par with each other registered lower cumulative loss of water (91.66 and 93.00 g/cut flower, respectively). The treatments T3 (STS @ 400 ppm + sucrose @ 2 per cent + 8- HQS @ 100 ppm), T1, T6 (cobalt sulphate @ 1000 ppm + sucrose @ 2 per cent + 8-HQS @ 200 ppm) and T7 (aluminium sulphate @ 1000 ppm + sucrose @ 2 per cent + 8-HQS @ 100 ppm) which were on par with each other recorded higher water balance (-5.66, -6.33, -6.00 and -6.00 g/cut flower, respectively). Higher fresh weight of cut flowers was registered by the treatments T4 and T8 which were on par with each other (9.33 and 10.00 g/cut flower, respectively). Higher stem browning (100%) was recorded in the treatment T6. The longest vase life of 14.33 days was recorded with the treatment T7. Beneficial and economical total cost to vase life ratio of 1.05 was associated with the treatment T7 (aluminium sulphate @ 1000 ppm + sucrose @ 2 per cent + 8-HQS @ 100 ppm).

    ALLEVIATION OF CHILLING INJURY OF CUSTARD APPLE (Annona squamosa L.) FRUITS
    (University of Agricultural Sciences GKVK, Bangalore, 40865) PATIL RAGHWENDRA, ARUNRAO; SUDHAKAR RAO, D. V
    Experiments were conducted to study the effect of modified atmosphere packaging (MAP) on alleviation of chilling injury in custard apple (Annona squamosa L.) fruits. Three different kinds of flexible films viz. low density polyethylene (LDPE), Cryovac Opti 300 and Cryovac PD-961 of 30×25 size were used for packing the fruits. Eight fruits were packed in each film bag and these packs were further packed in ventilated CFB boxes. The boxes were stored in “Walk-in” cold rooms maintained at 8, 12 and 15 oC (85-90 % RH) respectively. Each treatment was replicated thrice. At weekly intervals the fruits stored at different temperatures were taken out from film and allowed to ripen at room temperature (RT) to study their ripening behaviour. Experiments revealed that MAP of custard apple fruits with LDPE or Cryovac PD-961 film could alleviate the chilling injury to considerable extent, besides extending the storage life. Furthermore, MAP at lower temperature could maintain the quality of the fruits for a longer duration (two weeks) when compared to non-packed fruits at RT (four days). Fruits stored at 8oC though maintained their quality up to three weeks of storage, but lacked desirable appearance due to development of chilling injury. At 12oC, the fruits could be kept in unripe condition up to two weeks, when the fruits were packed either in LDPE or Cryovac PD-961 film. These fruits ripened normally without CI in three days when they were shifted to RT after unpacking. However, at 15oC the MA packed fruits ripened within the pack by two weeks of storage life when compared to one week in nonpacked fruits. Hence, it can be concluded that the storage life of custard apple fruits could be extended at 12oC without any CI by packing the fruits in LDPE or Cryovac PD-961 film.
