Research Paper (postgraduate) from the year 2015 in the subject Agrarian Studies, University of agriculture Faisalabad (Horticultural Sciences), language: English, abstract: Salinity is a severe problem of horticultural crops and field crops throughout the Pakistan. The experiment was conducted at the vegetable area, Institute of Horticultural Sciences, University of Agriculture, Faisalabad under different salinity levels in plastic pots. Four salinity levels (2.91, 3.90, 1.51, and 1.45 dS m-1 NaCl) to four different leafy vegetables (lettuce, spinach, coriander and fenugreek) were applied. Hoagland's solution was used as nutrient medium. Foliar applications of five concentrations of chitosan (0, 50, 75, 100, 125 ppm) and salicylic acid (0, 69.5, 347.5, 695 ppm) were applied. The data was collected regarding mortality (%), germination (%), total dry weight (g), total fresh weight (g), number of leaves, chlorophyll contents (CCI), shoot length (cm), root length (cm), nitrogen (N) concentration (mg g-1 DW) and protein contents (mg). Data of each treatment will be subjected to the statistical analysis using standard procedure. It was concluded that in leafy vegetables by increasing the levels of chitosan and salicylic acid, that total plant length, fresh weight, shoot length, root length, mortality percentage, nitrogen contents and protein contents increased. It was reported that by increasing the levels of chitosan and salicylic acid total dry weight and chlorophyll contents were decreased.
