    (University of Agricultural Sciences, Bangalore, 2018-08-01) SIDDESHWARA, G.N.; Eswarapppa, H.
    An investigation was undertaken to explore the potential of foxtail millet for development of foxtail millet flakes. The process parameters are soaking for 24 hours; cooking at 85ᵒC/10 minutes and drying at 65ᵒC for 1 hour were found to be optimum than other treatments for producing good quality flakes. The flakes were subjected to evaluation of physico-chemical, nutrient, sensory, and storage quality of flakes. Thousand flake weight and volume of the millet flakes were 2.36g and 14.97 ml, respectively with bulk density and true density of 0.15 g/ml and 0.37 g/ml respectively. The expansion ratio of Foxtail Millet Flakes was 8.04. The millet flakes had water holding capacity (13.14%), water absorption capacity (198.8%), water absorption index (196.98), water solubility index (2.57) and oil absorption capacity (99.7%). The millet flakes had moisture, fat, protein, total ash, crude fibre, carbohydrate and energy of 9.80, 0.69, 13.21, 1.23, 9.06, 63.40 per cent and 271 kcal, respectively. The microbial load was within permissible limit during storage period. The foxtail millet flakes were most acceptable in terms of sensory quality and had shelf life of two months at ambient temperature. It was concluded that foxtail millet flakes preparation could be a main avenue for utilizing foxtail millets.

    CHARACTERIZATION OF RAINFALL IN HAVERI DISTRICT
    (University of Agricultural Sciences, Bangalore, 2018-08-01) RAGHAVENDRA, C.S.; Gowda, D.M.
    The amount of rainfall and its pattern is one of the important factors that affect agricultural system. The analysis of rainfall data for long period provide information about pattern and its variability. For this purpose daily rainfall (mm) data pertaining to all taluks of Haveri district were collected from the AICRP on Agro meteorology, UAS, GKVK for the period of 32 years from 1982-2013.68. The average annual rainfall in the district during the study period was found to be 746.32 mm with a coefficient of variation of 21.27 per cent. Sixty eight per cent of the annual rainfall was received from South-West monsoon of which September month received highest amount of rainfall in the district. Mann Kendall test has revealed that all taluks of the district have registered non- significant positive trend. However, two taluks namely Byadgi & Hirekerur were found to have positive significant trend in annual rainfall out of seven taluks. The probability distribution viz., Normal, lognormal, Gamma (1P, 2P, 3P), General extreme value (GEV), Weibull (1P, 2P, 3P), Gumbel and Pareto were fitted for rainfall data of different periods of the district to observe pattern and goodness of fit was tested using Kolmogorov– Smirnov test. From the analysis, Weibull and Normal were found to be best fitted distributions for annual and seasonal rainfall data respectively. For Standard Meteorological Week 23rd to 39th SMW of rainfall data, Gamma, Log-Normal, Weibull and GEV were found to be the best fit distributions.

    STAGGERING AND OPTIMIZATION OF PLANTING RATIOS TO MAXIMIZE THE SEED YIELD AND QUALITY OF SINGLE CROSS HYBRID MAIZE MAH 14-5 (Zea mays L.)
    (University of Agricultural Sciences, Bangalore, 2018-08-01) ANIL KUMAR, G. S.; RAMANAPPA, T.M.
    The present investigation was carried out in two field experiments, one being the staggered sowing to study synchronization of flowering between female (CAL 1443) and male (CML 451) parents of single cross hybrid maize, MAH 14-5 during kharif 2017. The experiment was laid out in RCBD design with five treatments and four replications. The female and male parents sown on same day (S3) showed better synchronization in flowering which in turn resulted significant enhancement in yield parameters like ear length (18.33 cm), number of seeds per row (28.15), ear weight (140.35 g), seed weight per ear (115.75 g), seed yield per plant (140.10 g), seed yield per plot (2.24 kg) and seed yield per ha (34.09 q) in female parent. Another experiment was carried out to optimize the planting ratios during summer 2018. The experiment was laid out in split plot design with five main plot treatments (planting ratios) and two sub plot treatments (zinc nutrient). Planting ratio of 4:2 (female : male) registered significantly higher values for ear weight (141.63 g), ear diameter (4.65 cm), ear length (18.55 cm), number of seed rows per ear (16.13), number of seeds per row (28.13), seed weight per ear (115.75) and seed yield per plant (135.49 g) in seed parent. However, significant differences for seed yield per plot (8.96 kg) and seed yield per ha (35.10 q) was observed in 4:1 planting ratio. Hence, the study concluded that the sowing of male and female parents on same day with planting ratio of 4:1 could achieve better synchronisation of flowering in parents higher seed quality attributes and yield of seed parent.

    STUDIES ON DIVERSITY OF BEETLE ACROSS THE RURAL-URBAN GRADIENTS OF BANGALORE DISTRICT
    (University of Agricultural Sciences, Bangalore, 2018-08-01) JAGADEESH, KANASOGI; JEMLA NAIK, D.
    Urbanization is a dominant process of land alteration converting rural undisturbed areas into urban land. Now a days, the world is facing greatest ever biodiversity crisis due to urbanization, which leads to extinction of many species of plants and insects. The present study examined changes in abundance and diversity of beetles across the rural-urban gradients of Bangalore district during 2017-18. Using four methods of collection (light trap, sweep net, malaise trap and bee bowl) a total of 20,978 beetles of 271 morpho-species belongs to 30 families were collected. Among beetles, Staphylinidae contribute 72 per cent followed by Scarabaeidae and Carabidae. The light trap was found more efficient and effective for beetle collection as ninetythree per cent of total beetles were collected compared to other methods used in the study. The abundance and diversity of beetle were recorded more in post monsoon compared to pre-monsoon. During both the seasons, highest number of beetles were collected from rural gradients (8034) followed by peri-urban (6580) and urban gradients (5006). Shannon diversity index value was highest in peri-urban areas (H’=3.85) followed by rural (H’=3.81) and urban (H’=3.62). But, there were no significant differences were observed in both abundance and diversity of beetles across the gradients. Beetle diversity had shown positive correlation with diversity of vegetation. The present findings suggest that beetle can be used as a bio-indicator as it contributes 40 per cent of total insects species collected. Further, ecological health of a given area can be determined easily using beetle diversity.

    (University of Agricultural Sciences, Bangalore, 2018-08-01) SHILPA, G.; NAGARAJA, G.N.
    The present study was conducted to know the consumption pattern of Almonds and Almond based products in Bengaluru City. The data was collected through pre-tested schedule from 90 consumers and analyzed using descriptive statistics and factor analysis. The study revealed that consumers mostly preferred unbranded Almonds and branded Almond hair oil. The important factors influencing the consumers to consume Almonds and Almond based products were health benefit, routine habit, influence of family members, advertisements, offers, taste, income, brand image and nutritious. Further,62.22 per cent of consumers consume Almonds and Almond based products in once in a month followed by 14.44 per cent daily, 10.02 per cent festival season, 8.88 per cent once in a week and only 4.44 per cent of consumers consume occasionally. Households prefer retail shop (54.28 %) with least preference was online shopping (2.85%) for purchase of raw Almonds. Television was the major source of information to consumers for purchase of Almonds and Almond based products. From this, it can be suggested that the modern retail outlets can display health benefits and medicinal importance as well as nutritional value on the top of shelves that influence most of the consumers to purchase Almonds and Almond based products.

    EFFECTS OF PLANTING GEOMETRY ON SEED YIELD AND QUALITY IN FINGER MILLET (Eleusine coracana L. Gaertn)
    (University of Agricultural Sciences, Bangalore, 2018-08-01) NCEDISO A., MKHONTA; SIDDARAJU, R.
    Finger millet (Eleusine coracana (L.) Gaertn) is a staple food crop grown by subsistence farmers in the semi-arid tropics and sub-tropics of the world under rainfed conditions. Finger millet is a profuse tillering crop that requires optimum spacing for proper utilisation of light and plant nutrition to express its seed yield potential. Considering the crop characteristics and the need of quality seeds and maximum seed yield for the subsistence farmers, a field experiment was carried out to study the effects of planting geometry on seed yield and quality in finger millet (Eleusine coracana L. Gaertn) at J-Block, NSP, GKVK, UAS, Bengaluru during kharif 2017. The treatments were arranged in Randomized Complete Block Design (RCBD) with four replications, each replicate consisting of six different planting geometry viz., Rectangular method at 20 x 10 cm (G1) solid row, Rectangular method at 20 x 20 cm (G2) paired row, Square method at 20 x 20 cm (G3), Square method at 30 x 30 cm (G4), Square method at 45 x 45 cm (G5) and Square method at 60 x 60 cm (G6). The results indicated that planting geometry treatment (G2) rectangular method @ 20 x 20 cm paired row recorded maximum seed yield per hectare (55.64 q/ha). This is mainly due to maintenance of optimum plant population per unit area. While yield attributing characters like number of tiller per hill (7.68), number of fingers per ear head (7.30) and seed yield per plant (65.75 g) were significantly maximum in square method at 60 x 60 cm (G6). This may be due to efficient utilization of resources as the individual plant got more area for absorption of plant nutrients and more light and air for better development of growth characters (Ram et. al., 2013.) Hence, the study could be concluded that rectangular method at 20 x 20 cm paired row plant geometry was found to be suitable for increasing the seed productivity of finger millet

    (University of Agricultural Sciences, Bangalore, 2018-08-01) PRUTHVISHREE, C.; PARAMESH, R.
    The field and laboratory experiments were conducted to study the effect of planting geometry and nutrition on plant growth, seed yield and quality of okra at NSP, UAS, Bangalore. The experiment was laid out in FRCBD design with 12 treatment combinations replicated thrice which includes three different planting geometry S0 (60 × 45 cm), S1 (60 × 30 cm) and S2 (60 × 60 cm), four levels of nutrients N0 (100 % RDF), N1 (125 % RDF), N2 (150 % RDF) and N3 (200 % RDF) (RDF : 156.25: 93.75: 78.75 kg NPK ha-1). Results revealed that S2 and N1 are superior in plant growth and seed yield attributes viz., plant height (171.79 cm), number of leaves (28.23), number of branches (3.90), internodal length (10.80 cm) and chlorophyll content (60.83 SPAD unit), maximum seed yield plant-1 (69.06 g), seed yield plot-1 (1115.45 g) and seed yield ha-1 (19.36 q) registered and highest seed quality parameters documented under S2N1 such as germination (89.50 %), mean seedling length (35.65 cm), mean seedling dry weight (57.22 mg), seedling vigour index-I (3190) and II (5121) and 100-seed weight (8.60 g). Seed quality was evaluated based on fruit position with FCRD design replicated thrice consisting of three fruit position top (P1), middle (P2) and bottom (P3). It was found that bottom fruits (P3) produced highest quality seeds with maximum germination (88.61 %), mean seedling length (32.77 cm), mean seedling dry weight (50.32 g), seedling vigour index-I (2927) and II (4474), 100-seed weight (7.53 g) and total dehydrogenase activity (2.80), while electrical conductivity (674 μScm-1) of seed leachates recorded minimum in seeds from bottom fruits of okra.
