Abstract:
Two year field experiment was conducted at Rajasthan Agriculture Research Institute, Durgapura, during rainy seasons of 2016 and 2017 in split plot design with three replications to study the growth, productivity and economics of fenugreek - pearl millet cropping system by using four levels of phosphorus (0, 20, 40 and 60 kg P2O5/ha /ha) and six treatments of zinc and zinc solubilizer [0, 2.5 and 5.0 kg Zn/ha, zinc solubilizer (Bacillus endophyticus), 2.5 kg Zn/ha + zinc solubilizer & 5 kg Zn/ha + zinc solubilizer) applied to fenugreek. Results revealed that total nitrogen and phosphorus contents of pearl millet were increased significantly up to residual effect of 40 kg P2O5/ha while, potassium and zinc contents were not influenced significantelly. However, the significant increase in uptake of nutrients nitrogen, phosphorous, potassium and zinc were obtained up to 60 kg P2O5/ha by the tune of 90.5 and 99.5 per cent over control, during the years 2016 and 2017 except 20 kg P2O5/ha.
The highest nitrogen and zinc contents and uptake values were obtained with 5 kg Zn/ha + zinc solubilizer. The residual effect of 2.5 kg Zn/ha + zinc solubilizer was at par with 5 kg Zn/ha. The increase in total uptake of zinc were 40.6 and 67.0 per cent, during respective years over control.
