Effects of broccoli-crispy salad intercropping on yield and quality under greenhouse conditions

Abstract

This research was conducted to determine the effects of intercropping system of broccoli-crispy salad on the yield, quality characteristics, and land equivalent ratio (LER) by comparing alone broccoli and crispy salad cultivation under greenhouse conditions in the autumn of 2006 and 2007. According to results of this study, the highest values in investigated criteria were found in mono cropping. The highest total yield of broccoli was obtained with 1.67 and 2.46 kg m-2 in mono cropping, respectively in the autumn of 2006 and 2007. Similarly, the highest total yield of crispy salad was established with 5.93 and 3.36 kg m-2 in mono cropping, respectively in the autumn 2006 and 2007. LER was found to be greater than 1 in broccoli and crispy salad combination for both periods. The highest value of LER was determined to be 1.64% in autumn 2007 period.   Key words: Broccoli, crispy salad, greenhouse, yield, quality, intercropping, colour measurements.
