Impact and Assessment of Frontline Demonstration (FLD) Management of Weeds in Pineapple by Plastic Mulch

Twenty-five numbers of frontline demonstrations were conducted on management weed in pineapple by plastic mulch 2014-2016 & 2016-2018 subsequently with an ultimate aim to supressed growth weeds and boost farmer income because weeding accounts approximate 30–40% the overall cost crop. Pineapple cultivation 50 micron black polythene sheet mulching double row spacing i.e. 90 x 60 30cm not only suppresses but conserves soil moisture, which leads early flowering, better vegetative higher yield over control (Farmer practice). The demonstrated recorded average ranging from 43.18 45.90 t/ha a mean 44.54 t/ha. per cent increase demonstration 49.77% during 2014-16 66.67% 2016-18 respectively, practice. ranges extension gap (14.35- 18.36 t/ha), technology (9.10- 11.82 t/ha) index (21.49-16.55%) period under study. field gave gross return (Rs. 267240 /ha) net returns 191740/ha) benefit: ratio (3.54) compared local checks (1.71). Present results clearly show that economics can be up adoption recommended technology.
