Abstract:

Field experiments were carried out at Adaptive Research Farms, with the aim to study the influence of trace element on take up of phosphorus, potassium and nitrogen on wheat yield. RCBD design was used having three replications. Samples of soil were collected prior the sowing of wheat crop at a depth of 0-15 cm and were examined for chemical and physical properties (pH, soluble anion and cations, ECe, soil organic matter and texture, NPK and Fe). (Wheat variety) was planted during Rabi season 2005-2006 and 2006-2007. The recommended doses of N, P and K were applied @ 150:100:60 kg/ha, respectively, through broadcast at the time of sowing while N was applied in two equal doses after 25 and 40 days of sowing at the time of irrigation. Micronutrient, i.e., Fe was applied @ 0, 4, 8, 12 and 16 kg/ha unaided in the form of Iron sulphate at sowing time. All crop management and protection measures were followed. Results of the different studies conducted showed that application of Fe increased NPK uptake and their concentration in soil significantly over control. Application of recommended NPK improved micronutrient (Fe) uptake appreciably and this resulted in a slight decreased micronutrient (Fe) contents in soil as compared to control. Micronutrients application enhanced the yield and growth parameters of wheat, their total take up also effect in the build-up of micronutrients in the upper 15 cm soil layer, to be available for next crop. Application of Fe also showed a noteworthy response to wheat at lower rates, when applied alone. Severe decrement of Fe didnít effect the growth and yield contributing parameters of crop. The results of our study reveal that the application of Fe has no significant effect on the NPK uptake by wheat crop.
