Abstract

Summer squash is a short-duration vegetable crop with off-season nature and high economic returns per unit area. However, the early crop growth season encounters a number of abiotic stresses like low temperature and frost, which adversely affect the marketable yield and quality of the fruits. This dependency on natural factors restricts the scope of its profitable cultivation, thereby making it necessary to bring more area under protected cultivation. Coloured plastic mulches are an important component of protected cultivation, which are designed to modify the microclimate at the plant and soil levels so as to increase crop production and productivity, as well as quality of the produce, to meet the demands of the consumers. Keeping these considerations in view, the present field investigation was conducted at the Vegetable Research Centre of G. B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) during the rabi season of 2019-20 to study the effect of different coloured plastic mulches on the growth and yield of summer squash (Cucurbita pepo L.). The experiment comprised nine treatments (bi-coloured plastic mulches) replicated thrice in a randomised block design. Results revealed that use of different coloured plastic films significantly influenced the growth and yield parameters of summer squash. Red coloured plastic mulch (V1) recorded the maximum values for fruit length (30.78 cm), fruit yield plant-1 (1975.8 g), fruit yield plot-1 (39.51 kg) and total marketable fruit yield (365.52 q ha-1), while biodegradable film of silver-black colour (V7) and black plastic mulch (V4) recorded the maximum plant height (cm) and plant spread (cm), respectively. The maximum diameter of the fruit (110.13 mm) was recorded under black coloured plastic mulch. Considering the prevalent climatic conditions of the tarai region of Uttarakhand, red coloured plastic mulch can be recommended for commercial cultivation of summer squash for obtaining higher fruit yields.
