Abstract:
Mulching plays an important role for reducing moisture loss, weed growth, and increasing
yield of fruits and vegetables. The present experiment aimed to find out the effect of
different mulch materials and gibberellin on growth, yield, and quality of strawberry under
net house condition during the period from October 2020 to February 2021. The
experimental treatments included four mulch materials: no mulch, black polythene, white
polythene, and sawdust and two levels of gibberellic acid (0 and 200 ppm GA
3
). The
treatments showed significant effect on leaf area, SPAD value, relative water content,
number of fruits, and yield per plant, as well as quality traits i.e. total soluble solid, reducing
sugar, phenol and anthocyanin content of strawberry. Organic mulch (sawdust) produced
higher yields and quality than synthetic mulch (black and white polythene) and no mulch
conditions. GA
3
treated plants performed better than non-GA
3
sprayed plants. In terms of
interaction effects, sawdust mulch plants treated with GA
3
produced the highest fruit yield
(321g) per plant, while black polyethylene plants treated with no GA
3
produced the lowest
fruit yield (118g). Therefore, sawdust and GA
3
are beneficial for increasing the growth,
yield, and quality attributes of strawberry plants.
