This experiment was conducted to explore the shady places on agricultural land. In the experimental field it was done by giving different light intensity (with the help of shade net) to the crop along with different level of nitrogen. The field experiment was carried out in factorial Randomized block design with three replications, during Rabi season 2019-2020 in Horticulture Research Farm, Department of Horticulture, SHUATS. Experiment was setup in 18 treatments i.e. different levels of nitrogen in combination with different levels of light intensity (25% and 50%) on growth, yield and photosynthetic characteristics of giant mustard which include No. of leaves, Plant height (cm), Weight of plant (kg), Yield per plot (kg plot-1), Leaf thickness (mm), Fresh leaf mass (g), Light Intensity (lux), Atmospheric temperature (°C), Precipitation (mm). From the experiment, treatment combination T10 i.e. NPK (55:40:40) + 50% Shade (Green Net) was found superior for application of nitrogen @ 55 kg

Giant Mustard, NPK, Light Intensity, growth, yield.

It is concluded from the experiment that treatment combination T10 i.e. NPK (55:40:40) +50% Shade (Green Net) was found superior for application of nitrogen @ 55 kg ha-1 in blend with light intensity 50% suitable for enhancing growth, yield and photosynthetic characteristics of giant mustard. Level of NPK 55:40:40 and level of shade 50% recorded significantly higher values for growth and yield attributing characters, viz., number of leaves highest observed in treatment T10 [NPK (55:40:40) +50% Shade (Green Net)] was 15.55, plant height 43.10cm, Weight of plant 1558.33g, yield per plot 6.84 kg, Leaf thickness 0.79 mm, Fresh leaf weight 65.83g, Light Intensity (lux) 25% 9916.00 lux, Light Intensity (lux) 50% 8002.33 lux in comparsion with other treatments. Level of NPK (55:40:40) +50% Shade (Green Net) treatment also, shows at par results when compared to other treatments.
