The suspension systems in automobiles are to provide adequate flexure modulus and damping in response to the road tyre interaction. This will ensure adequate driving comfort. In this context, as a weight reduction measure and to provide sufficient response to the vehicle dynamics leaf springs made of composite materials and can be a replacement for traditional metal leaf springs. Hence the present study on the GFRP composite laminate is to experimentally simulate the loading environment in the vehicle and the response of spring leaf made of composite material. GFRP composite laminate specimen of configurations such as Unidirectional Laminate (UD-0), angle ply laminate (0/30/60/0 and 0/45/0/-45) and symmetric and non-symmetric cross ply laminates (0/90/90/0 and 0/90/0/90) are prepared by hand lay-up technique. The laminates are exposed to low cycle (4.6 Hz and 8.6 Hz), constant amplitude cyclic loading in the laboratory setup. The flexural modulus of the virgin and pre-cyclic loaded specimen is measured by three point bend test using digital UTM as per ASTM D 790. The flexural modulus of the pre-cyclic loaded laminate specimen presents a positive improvement up to certain loading cycles at low frequency (4.6Hz). At high frequency (8.6 Hz) loading cycles there existdegradation in the flexural modulus of the pre-cyclic loaded specimen. The enhancement and degradation of flexural modulus on exposure to cyclic loading signify the influence of loading cycle frequency and laminate configuration. Any variation in the specimen configuration apart from UD-0 ply, record a drop in the flexural modulus. The optimum flexural responses characteristics in composite material are attributed to the selection of lay-up configuration and loading condition.Keywords

A field experiment was conducted during Kharif 2015 at Zonal Agricultural Research Station, V.C. Farm, Mandya, Southern Dry Zone of Karnataka to study the growth and yield of maize as influenced by drip fertigation. The experiment was laid out in Randomized Complete Block Design with three replications and eleven treatments comprising two levels of irrigation and four levels of fertilizers, absolute control, package of practice and paired row of spacing 45 x 75 cm. Irrigation @ 100% cumulative pan evaporation+drip fertigation 125% recommended dose fertilizer was found higher kernel yield (7763 kg ha-1) and stover yield (8159 kg ha-1). Higher nitrogen, phosphorus and potassium use efficiency was recorded in irrigation @ 100% cumulative pan evaporation+drip fertigation 75% recommended dose fertilizer (65, 131 and 245 kg kg-1, respectively). Significantly higher water use efficiency was found in irrigation @75% cumulative pan evaporation+drip fertigation 125% recommended dose of fertilizer (132.17 kg ha cm-1) over University of Agricultural Sciences-package (74.18 kg ha cm-1). Higher cost of cultivation was recorded in irrigation @100% cumulative pan evaporation+drip fertigation 125% recommended doses fertilizer (Rs. 37089 ha-1) followed by irrigation @100% cumulative pan evaporation+drip fertigation 100% recommended dose fertilizer (Rs. 35379 ha-1).Keywords

A study was conducted to assess the adoption impact of technologies and its influence on the cocoon yield. The data were collected from 108 farmers of traditional sericultural area of Kolar district of Karnataka. In the present study, attempts have been made to identify and advocate the need based technologies for the selected farmers along with requis ite motivational efforts through personal interactions and group discussions held over a period of two years. Initial diagnostic study was conducted through structured proforma and impact survey was carried out and crop performance data computed for the 1st and 2nd years, which recorded an increase of cocoon yields by 8-19 kg/100 dfls among the target farmers. Among the technologies covered in the study, application of farmyard manure, separate chawki garden, separate chawki rearing room, proper disinfection of rearing house and equipments, black boxing and incubation of eggs, shoot feeding under shelfrearing and use of bed disinfectants mainly contributed for the increased cocoon yields.Keywords

The study was conducted in seven villages of Bangalore South district of Karnataka, covering a total of 127 farmers. Benchmark survey was conducted through personal interview by using structured proforma to resource the primary data to understand the existing practices and productivity levels, and for identifying the crucial factors. Further for intensive study, 30 among these 127 farmers were selected based on their willingness to adopt the suggested technologies. Regular interactions were held for two years on one-toone basis with these farmers along with motivational efforts for technological interventions as were enlisted for respective farmers. Impact survey was carried out and crop performance data computed for 1st and 2nd year, apart from compiling the information pertaining to the performance and suitability of the technologies and response of each of the farmers during the course of the study. The data revealed that cocoon yields increased by 8-13 kg with the adoption of identified technologies among the target farmers.Keywords

Laboratory incubation conducted to study the toxic effect of decomposition of Parthenium and Chromolaena and their respective compost under flooded condition. Increasing the level of organic carbon application through different sources increased the water extractable phenols, water insoluble alkali extractable phenols and total extractable phenols. The contents of the three forms of phenols increased from 15th to 45th day of flooding and then decreases. Plant height and ischolar_main length was maximum during sixty days after flooding with the incorporation of organic manures.Keywords

Laboratory incubation experiment was carried out to study the changes in the microbial biomass nitrogen and microbial biomass carbon under waterlogged condition of paddy soil with the use of parthenium and chromolaena as green manure and their compost. Based on the content of total C of plant material organic material applied at the rate of 0.5, 1.0 and 2.0 per cent level of organic carbon. The increase in extractable C and N in Mudigere soil alone was 30.81 mg kg-1, at 60th day of flooding. On 120th day of flooding the EC values of Mudigere soil alone was 32.47 mg kg-1. Similarly with time, the EN values also increased. The highest EC value was recorded in T10: Mudigere soil+Chromolaena compost @ 2.0% C at day 60 and 90 was 112.11 and 153.52 mg kg-1 soil, respectively. The EC: EN ratio in control was 7.91 in Mudigere soil whereas on 120th day of flooding the value was 7. On 120 day, it ranged from 85 to 381 mg kg-1 soil. On 120th day lowest biomass nitrogen (BN) (215 mg kg-1) was recorded in T5:Mudigere soil+Parthenium green manure @ 0.5% C. Increasing the C level resulted in increasing BN and BC, but to different degrees, depending on the native of C sources. Addition of different levels of organic manures to soils showed highly significant changes in nutrient content of soil over control at 60 and 120 days after flooding.Keywords

A laboratory incubation experiment was carried out to study the changes in the ammonical extractable nitrogen and phosphorus under submerged and well drained conditions of paddy soil with the use of Parthenium and Chromolaena as green manure and their compost. Based on the content of total C of plant material organic material applied at the rate of 0.5, 1.0 and 2.0 per cent level of organic carbon. In general NH+ 4-N and brays – P increased with the period of submergence, among different treatments maximum NH+ 4-N (138.67mg/kg) was noticed in T10: Mandya soil + Chromolaena compost @ 2.0 % C whereas least (92.23mg/kg) in T1: Mudigere soil alone and brays –P recorded highest (23.83 mg kg-1) in T10: Mudigere soil + Chromolaena as green manure @2.0% and least (11.84 mg kg-1) in T1:. Mudigere soil alone on 120th day of flooding. Increasing the level of organic carbon application increase the NH+ 4-N and brays –P. Under well drained conditions the ammonical nitrogen contents of all the treatments decreases rapidly and nitrate content increases whereas brays phosphorus also increases.Keywords
