Abstract

The present study was undertaken to find the effect of plastic mulch colors and foliar application of potassium on growth, yield and quality of strawberry in protected conditions. The combined effect of black polythene mulch and 1000 ppm potassium sulfate (K2SO4) enhanced the nutrient availability, efficient water use, moisture retention and temperature regulation which helps in strawberry growth, enhanced fruit quality and boost output. The study design of experiment was factorial randomized block design with 15 treatments and 3 replications with interaction of different plastic color mulch (Black, Blue, Red and Silver) with foliar application of K2SO4 (500, 1000, and 0 ppm) as treatments was used and analyzed the data using analysis of variance. Black mulch + 1000 ppm K2SO4 treatment gave the best results in term of increasing growth parameters i.e., plant height (16.13 cm2), no. of leaves (25.7), no. of branches (8.08), no. of crown (4.31), fruit weight (12.32 g), no. of flowers (26.30), no. of fruits (15.8), fruit yield/ plant (189.6 g), and also increases quality parameters like total soluble solids (TSS) (7.6 °Brix), ascorbic acid (48.7 mg/100 g), reducing sugar (5.34%), non-reducing sugar (2.47%), total sugar (7.95%) by decreasing acidity (0.55%) of strawberry fruits. It is concluded that interaction P1N2 (black mulch + 1000 ppm K2SO4) had a significant effect on enhancing the plant growth, yield and quality parameters of strawberry cultivar “Camarosa”.
