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.

    STUDIES ON SEED TESTING PROTOCOL AND SEED LONGEVITY IN CHIA (Salvia hispanica L.)
    (2023-01-12) UDAY, K. V.; S. N. VASUDEVAN
    A laboratory experiment was conducted at AICRP on Seed (Crops), UAS, GKVK, Bengaluru during 2021-22. Chia seeds were subjected to germination at different temperatures (20, 25 and 30 ℃) and substrates (sand, between paper and top of paper). Among the temperatures, higher germination (75.58 %), mean seedling length (14.23 cm) and seedling vigour index-I (1076) were recorded at 25 ℃. Among the substrates, higher germination (70.51%), mean seedling length (12.47cm) and seedling vigour index-I (891) were recorded in top of paper method. To study the seed storability, chia seeds were treated with four different chemicals (untreated, sweet flag @ 2g/kg, carbendazim @ 1g/kg and captan @ 2g/kg) and packed in three different packaging materials [cloth bag, super grain bag and polythene bag (700-gauge)]. Among the packaging materials, seeds stored in polythene bag (700-gauge) recorded better seed quality attributes viz., germination (66.34 %), mean seedling length (9.51 cm), seedling vigour index-I (635) and total dehydrogenase activity (1.089 A480 nm) up to ten months of storge. Among the chemicals, seeds treated with carbendazim @ 1g/kg resulted in higher seed quality parameters viz., germination (65.50 %), mean seedling length (9.66 cm), seedling vigour index-I (640) and total dehydrogenase activity (1.030 A480 nm). It is concluded that, temperature of 25 ℃ and top of paper method seems to be ideal for testing seed germination of chia and seeds could be stored up to ten months under ambient condition by treating with carbendazim and packed in polythene bag (700-gauge).

    STUDIES ON THE EFFECT OF SOWING WINDOWS ON SEED YIELD AND QUALITY OF CHIA (Salvia hispanica L.)
    (2023-01-12) PRASANKUMAR, B. GURUVANNAVAR; S. N. VASUDEVAN
    Experiment was conducted to study the effect of sowing windows on seed yield and quality of chia at Zonal Agricultural Research Station, V. C. Farm, Mandya, during Kharif season 2021. The experiment consisted of six treatments with different sowing dates viz., 13th June-(T1), 28th June-(T2), 12th July-(T3), 26th July-(T4), 12th August-(T5) and 28th August-(T6) in Randomized Block Design with four replications. Results revealed that, growth and yield parameters in terms of plant height, number of leaves, number of spikes and seed yield ha-1 were significantly higher in 12th August sowing (93.70cm, 41.90, 14.75 and 841.87kg, respectively) followed by 26th July sowing. Further, to standardize suitable screen aperture size for processing of chia seeds, experiment was carried out using two types of bottom screens (Slotted-S and Round-R) with different size viz., S(0.8mm), S(0.9mm), S(1.0mm), R(1.1mm), R(1.3mm) and R(1.5mm) with four replications in Completely Randomized Design. The screen aperture size S(0.8mm) recorded maximum seed recovery (98.25%), physical purity (96.46%), germination (73.33%), real value of seed (70.74%), seedling length (13.13cm), seedling vigour index-I (962) followed by R(1.1mm) with seed recovery (96.87%), physical purity (96.77%), germination (72.33%), real value of seed (70.01%), seedling length (12.81cm), seedling vigour index-I (926). It is concluded that, sowing of chia crop either during last week of July or first fortnight of August is ideal for quality seed production and processing of chia seeds can be done either by using slotted 0.8mm or round 1.1mm screen aperture size for better seed recovery with good seed quality parameters.
