Influence of Spacing and Nutrition on Yield and Economics of Lettuce (Lactuca sativa L.) under Protected Cultivation
Year: 2025
Type: article
Abstract: This research was done to investigate the influence of spacing and nutrition on its yield and cost economics under protected cultivation of lettuce (Lactuca sativa L.) during Rabi of 2021-22 at ICAR-KVK, Hadonahalli of Karnataka. It was undertaken with Factorial Randomized Complete Block Design, to study the application of three different spacing such as 45×22.5 cm, 45×30 cm and 45×45 cm and three nutrient levels such as 75%, 100% and 125% of Recommended Dose of Fertilizers (RDF) along with 25 t ha-1 FYM. The results revealed that significantly higher head girth (12.93 cm) and yield per plant (407.02 g) were recorded at 45 cm × 22.5 cm spacing. The higher head girth (12.80 cm), yield per plant (388.45 g) and yield per hectare (280.63 q ha-1) was recorded with application of 125% RDF. However, higher net returns (Rs. 10,26,435 /-) and higher cost benefit ratio (3.07) were recorded in 45 cm × 22.5 cm spacing + 125 % RDF.
