Abstract
A field experiment was conducted to study the “Response of wheat (Triticum aestivum L) to different levels of Nitrogen (N) and foliar spray of nutrient mixture under Gharuan conditions of Punjab (India)” during Rabi 2020-2021 at Agriculture Farm of Chandigarh University. The soil of the experimental field was sandy loam to clay neutral in reaction and having neutral pH and medium range of organic carbon, low in available nitrogen, phosphorus and potassium. The experiment was laid out in split plot design with four levels of nitrogen(30,60,90,120 kg N ha-1) in main plots and four Foliar spray of nutrient mixture(F1 = 2% DAP + 1% KCL, F2= 2% DAP+ 1% KCL+ Nutrient mixture,F3= 2% DAP + 1% KCL+100ppm Salicylic acid, F4= 2% DAP +1% KCL+ 100ppm maleic hydrazide, nutrient mixture prepared by 0.5% MgSO4, 0.25% ZnSO4 and 0.1% Boric acid) in sub plots. The results showed that, highest yield, yield attributing characters and growth attributes viz. plant height, dry weight plant-1, number of tillers plant-1, LAI, 1000-grain weight, fertile spikelets/ear, Ear length as well as number of spikes plant-1 were recorded with the application of 120 kg Nha-1 and foliar spray of 2% DAP + 1% KCl + nutrient mixture (F2) whereas lowest value of yield and growth attributes was recorded with application of 30 kg Nha-1 and foliar spray of 2% DAP + 1% KCl + 100 ppm maleic hydrazide (F4). Besides, foliar spray of 2% DAP + 1% KCl + 100 ppm salicylic acid 100 ppm (F3) and 2% DAP + 1% KCl (F1) also recorded significantly higher values of these growth characters over F4 treatments.
