A field experiment was conducted to study the effect of fertilizer mixture on soil available nutrient content. The experiment was conducted at Maize Research Station, Vagarai, Dindigul district, Tamil Nadu in Randomized BlockDesign with seven treatments replicated thrice. The treatments included the application of 120 kg urea+ 50 kg DAP -Farmers' practice (T1), Farmers' practice with Tamil Nadu state Dept. of Agriculture micronutrient mixture @ 25 kg ha-1 as straight chemical fertilizers (T2) as well as EFYM (T3), recommended dose of fertilizer (T4), RDF with TNAU -micronutrient mixture @ 12.5 kg ha-1 as straight chemical fertilizers (T5), RDF with TNAU - micronutrient mixture @25 kg ha-1 as straight chemical fertilizers (T6) as well as EFYM (T7). The availability of macro and micronutrients were recorded at different stages of maize crop growth like knee high stage, tasseling and at harvest stage. The experimental result has revealed that though the availability of nutrients decreased with the advancement of crop growth, application of recommended dose of fertilizer with 25 kg ha-1 of TNAU micronutrient mixture as enriched FYM has registered the increased availability of macro and micro nutrients even in post harvest soil.Keywords

Control valves are an increasingly vital component of modern manufacturing around the world, since control valves are mechanical devices, their performance is less than ideal, and degrades over time. For a plant to perform optimally control valve performance must be tracked and maintained. Backlash is one of much invertible nonlinearity present in control valve, if a valve has some backlash, the loop will have a tendency to oscillate, which will get bigger and bigger as time goes by and will also make the loop slower to respond. At present, pneumatic valve Positioner is used which uses mechanical cam to correct the non-linear nature of control valves. Pneumatic valves Positioner typically are very simple and do not implement integral control. In this project a novel low cost Smart Positioner is designed and developed to improve the performance of control loops. A rotary potentiometer with a linear actuator is used to give feedback signals to the controller of the current position of the control valve. A specially designed control system which is cascade in nature increases the performance of the control system. The Position sensor control being a slave controller acts faster to position the valve and thereby avoiding backlash problem. The developed design is implemented in the Second Order Two Tank Level control system and the performance metrics such as Rise time, Settling time and Steady state errors evaluated found improved after implementing smart Positioner. The oscillation of control valve was found minimum compared to pneumatic Positioner which clearly an indication of reduced backlash in the system. The low cost smart Positioner is RVDT which fixed on a pinion rack and interfacing the proposed second order system using MATLAB for error analysis and LabVIEW software and NI DAQ6008 to run the proposed second order system.Keywords

Soil hydraulic properties are important for irrigation scheduling and proper land-use planning. Field capacity, permanent wilting point and infiltration rate are the three vital hydraulic properties which determine the availability and retention of water for crop growth. These properties are difficult to measure and time-consuming, but can be easily predicted from the available information like soil texture, bulk density, organic carbon content, etc. through pedotransfer functions (PTFs). PTFs were developed for field capacity and permanent wilting point for two different regions of Karnataka, viz. Northern Karnataka Plateau (512 soil samples) and Southern Karnataka Plateau (228 soil samples), separately. PTF for infiltration rate was developed using 100 soil samples for the entire Karnataka. Cross-validation techniques were used to validate the PTFs, and the results are satisfactory with low RMSE and higher R2. The developed PTFs are useful in determining soil hydraulic properties of the semi-arid regions of southern India.Keywords
