Integrated soil nitrogen and foliar application of trace elements could increase crop growth and yield and decrease environmental pollution. In order to explore the impact of soil applied nitrogen and foliar applied micronutrients on safflower growth and yield, a field experiment was conducted at Soil Chemistry Section, Agriculture Research Institute, Tandojam, during Rabi season in 2016-17.Seven treatments and three replicates were used for each treatment. T1 (control), T2, T3 and T4, T5, T6 and T7 = 50, 100 and 150 kg N ha-1 (soil) + 1250 ml and 2000 ml ha-1 (foliar) were used respectively. The present study revealed that the crop was treated with N @ 150 kg ha-1 (soil) + Gillette (Micronutrients mixture) @ 2000 ml ha-1 (foliar) produced maximum plant population (42.2 m-2), plant height (126.2 cm), branches plant-1 (11.0), seeds capitulum-1 (42.9), seed index (1000 seed weight, 44.0 g) and seed yield (2400 kg ha-1) as compared to N @ 100 kg ha-1 (soil) + Gillette(Micronutrients mixture) @ 2000 ml ha-1 (Foliar) which was recorded plant population (41.1 m-2), plant height (124.8 cm), branches plant-1 (10.0), seeds capitulum-1 (41.9), seed index (43.0 g), and seed yield (2350 kg ha-1). While the lowest results for all parameters were recorded in control. It is obvious from the results that N @ 100 kg ha-1 (soil) + Gillette (Micronutrients mixture) @ 2000 ml ha-1 (Foliar) recorded optimum results due to medium dose of nitrogen and non-significant differences ([email protected]%) with T7 and T4 where highest dose of nitrogen was applied.
