| The
effects of low black polyethylene tunnels on the performance of 35
strawberry cultivars were investigated at Shimla, India, during 1996-98.
Covering beds with black polyethylene hastened flowering by
approximately 1 month, prevented soil erosion, reduced weed growth and
winter injury, and increased total yields by 20%. Weeding was not
required in mulched beds. During summers, the replacement of plastic
sheets with anti-hail or anti-bird nets increased the yields and
improved fruit quality. Variation in cultivar performance was also
observed. Under uncovered conditions, Shimla Delicious gave the highest
number of fruits per plant (30) while Etna and Belrubi the highest yield
per plant (243.80 and 213.20 q/ha). |
