A three year field experiment was conducted during September - March of 2010-2011 to 2012- 2013 at Agricultural College and Research Institute, Killikulam to study the influence of humic acid with graded levels of inorganic fertilizers on productivity, nutrient uptake, economic and soil fertility of brinjal var KKM1. The experiment was carried out in Randomized Block Design replicated thrice with 11 treatments. Humic acid was applied through both in soil and foliar spray with 75 per cent RDF (N75 P37.5 K22.5). Application of 75 per cent RDF (N75 P37.5 K22.5) + 10 kg HA (SA) + 0.2 per cent HA (FS) /ha produced significantly higher plant hight (112.0 cm), days to 50 per cent flowering (56.4), number of branches/plant (9.4), number of fruits /plant (25.3), single fruit weight ( 69.9 g), fruit yield (33.4 t/ha), total dry matter production (10.08 t/ ha), net return (Rs. 1,33,131 / ha) and B:C ratio (4.29), N, P and K (143.1, 33.3 and 148.6 kg/ha, respectively) uptake compared to control. However, 75 per cent RDF (N75 P37.5 K22.5) + 10 kg HA (SA) + 0.1 per cent HA (FS) /ha had higher plant height, number of branches, days to 50 per cent flowering, number of fruits per plant, single fruit weight, fruit yield, total dry matter production, net return, B:C ratio, N,P and K uptake. Significant built up of organic carbon (0.92 %), available N (291.5 kg/ha), available P (25.4 kg / ha) and available K (293.7 kg / ha) was registered with 75 per cent RDF + 10 kg HA (SA) + 0.2 per cent HA (FS) /ha. The maximum balance of N, P and K (25.5, 8.6 and 25.2 kg/ha, respectively) were recorded under the treatment with application of 75 per cent RDF + 10 kg HA (SA) + 0.2 per cent HA (FS) /ha.Keywords

Knowledge of spatial variability in soil fertility is important for site specific nutrient management. In the current study, the spatial variations of soil pH, organic carbon, N, P, K, Fe, Cu, Mn and Zn were evaluated in Orathur village (Typic Haplusterts) of Veeranam command area of Cuddalore district, Tamil Nadu. Global positioning system (GPS) guided surface soil sampling (0-15 cm) were done over an area of about 100 hectares in a 100 x 100 m grid. Wide ranges of variation were noted for different soil physico-chemical properties as well as nutrient status in the study area. The pH of soils ranged from 6.70 to 8.30, organic carbon ( %) varied from 0.49 and 0.88, available nitrogen (kg ha-1) from 173.60 to 235.20, available phosphorus (kg ha-1) content varied from4.90 to 17.10, available potassium varied between 180.00 to 330.0 kg ha-1, while available S content varied from 3.10 to 21.30 ppm. The available Fe and Mn varied from 3.26 to 20.16 ppm and 0.94 to 8.26 ppm. The variation of soil nutrient contents across the study area was found to be related to the fertilizer use pattern among farmers. The evaluated physico-chemical and nutrient status data of the area were used to develop variability maps with the aim of generating site -specific nutrient management strategies.Keywords

The present investigation is aiming to get better squeeze film dampers which are normally used in high speed jet engines to minimize small amplitude large force vibrations. The investigation was started with squeeze film dampers employing conventional lubricating oils. Magneto rheological fluids are then used to enhance the viscosity characteristics of the fluid under the influence of magnetic fields in order to improve the damper performances. It is observed that the dynamic characteristics of the damper with magneto rheological fluids are enhanced. Further to improve the damper performance, few modifications in the damper assembly are carried out in this research work. A good amount of reduction in the amplitude of vibrations is observed in these modified squeeze film dampers coupled with magneto rheological fluids. This research work discusses dual and triple clearance squeeze film dampers and bump foil squeeze film damper, also subjected to variation in temperature. Dynamic characteristics are found to be decreasing as the viscosity of the fluid decreases with rise in temperature of the fluid.Keywords

A study was carried out to characterize and classify the soils of Lower Palar-Manimuthar watershed, Tamil Nadu State using satellite data on 1:50,000 scale and to evaluate soils for their capability, productivity and suitability for agricultural crops. Ten soil series were recognised in the study area and they were classified as Entisols, Inceptisols and Alfisols. The soils were grouped under the land capability classes II, III, IV and V with soil and erosion as major limitation. Soil suitability for different land utilization types (LUT) were also assessed. The potential LUTs for each soil were suggested keeping into account the productivity index. Based on the major limitations, suitability to crops and productivity rating were calculated and these were integrated in GIS to generate action plan for sustainable development.Keywords
