Effects of different LED light and nitrogen application on growth of lettuce plants and leaf nitrate content

Artificallighting in greenhouse plant growthcome into use culturel introduction between recently. Led lighting plant aim to lighting period to increase goods early cultivation period and mineral material included above have influence. To this end, one year inside greenhouse landless cultivation conditions has been determined spring and autumn under artificial lighting plant growth above influence. Funnly F1 lettuce has been cultivation 2:1 in proportion cocopeat and perlit mixed habitat PVC noddle drip irrigation system use. Every parcel above sustained red, purple, blue and yellow impending 4 different led light source to place 3 noddle one parcel as and every noodle establisher 3 plant. Plants in all observed. Experiment as regulation coincidence parcel experiment desing properly 3 repetative. This study as a result of different led light marketable plant sports heavy weight, plant diameter, plant height and chlorophyll retefor above to the effect statistical as find unimportant SÇKM, pH and titratable acidity rates above effective statical find important.
