INFLUENCE OF DIFFERENT ORGANIC MANURES ON GROWTH, YIELD AND MINERAL NUTRIENT ACCUMULATION IN LETTUCE (LACTUCA SATIVA L.)

Abstract

Effects of organic manures on growth and yield of lettuce (Lactuca sativa L.)
and nutrient accumulation in its leaves was examined. The experiment was
conducted in a completely randomized design (CRD) replicated thrice with ten
treatments involving nine organic manures and a control treatment. Growth
parameters viz. plant height, leaf number, leaf length, leaf area, leaf area index
and fresh and dry weight of leaf, stem and root were assessed. The highest
height (23.69 cm), longest leaf (32.18cm), leaf area (5883.43cm2), leaf area index
(6.434), fresh weight (85.41 g) and dry weight (42.73 g) were found in Payel
organic manure. The maximum leaf number (27) was recorded in Approshika
organic manure. The maximum content of nitrogen (6.12%), phosphorus
(1.83%), potassium (4.11%) and Sulphur (1.69%) were observed in Payel organic
manure. The best growth performance and nutrient accumulation was observed
in Payel organic manure.
