Performance of broccoli (Brassica oleracea var. italica) under drip irrigation and mulch
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 3
Abstract
Field experiment was conducted at Central Research Farm of Bidhan Chandra Krishi Viswavidyala, Gayespur, West Bengal during winter seasons of 2011-12 and 2012-13 to assess the comparative effectiveness of drip and conventional surface irrigation with and without mulch on growth and yield of broccoli. The experiment was laid out in split-plot design replicated thrice. Main plot treatments consist of four levels of irrigation such as surface irrigation with IW/CPE 1.0 and three drip irrigation at 1.0, 0.8 and 0.6 ETc (crop-evapotranspiration), and three mulch levels like no mulch, black polythene mulch and paddy straw mulch @ 5t/ha in sub-plots. The results showed that drip irrigation at 0.8 ETc showed significantly higher (P = 0.05) plant height (45.69 cm), no of leaves plant-1 (17.66), leaf size index (743.99 cm2), plant spread (89.94 cm), curd diameter (14.43 cm) and marketable curd yield (17.82 t ha-1) of broccoli, which was at par with drip at 1.0 ETc. Minimum growth and yield was obtained with drip irrigation at 0.6 ETc in both the years. Similarly, significantly the highest (P = 0.05) plant variables and curd yield was obtained with use of black polythene mulch over paddy straw and no mulch treatments. However, drip irrigation at 0.6 ETc registered maximum water use efficiency of 117.31kg ha-mm-1 and water saving of 38.43%. The interaction effect showed that drip irrigation at 0.8 ETc along with black polythene mulch produced significantly higher marketable curd yield. The experimental findings can be recommended for growing high value crop broccoli with water saving drip irrigation at ETc 0.8 along with plastic mulch technology in the water scarce regions of West Bengal.
