Impact and Assessment of Frontline Demonstration (FLD) Management of Weeds in Pineapple by Plastic Mulch
Year: 2022
Type: article
Abstract: Twenty-five numbers of frontline demonstrations were conducted on management of weed in pineapple by plastic mulch 2014-2016 & 2016-2018 subsequently with an ultimate aim to supressed growth of weeds and boost farmer income because weeding accounts approximate 30–40% of the overall cost of crop. Pineapple cultivation with 50 micron black polythene sheet mulching with double row spacing i.e. 90 x 60 x 30cm not only suppresses the weed growth but conserves the soil moisture, which leads to early flowering, better vegetative growth & higher yield over control (Farmer practice). The demonstrated recorded an average yield ranging from 43.18 to 45.90 t/ha with a mean of 44.54 t/ha. The per cent increase yield in demonstration 49.77% during 2014-16 and 66.67% during 2016-18 respectively, over the farmer practice. The average ranges of extension gap (14.35- 18.36 t/ha), technology gap (9.10- 11.82 t/ha) and technology index (21.49-16.55%) were during the period under study. The demonstrated field gave higher mean gross return (Rs. 267240 /ha) and mean net returns (Rs. 191740/ha) with average benefit: cost ratio (3.54) compared to the local checks (1.71). Present results clearly show that the yield and economics of pineapple can be boost up by adoption of recommended technology.
