Use of geotextiles for improving crop productivity on groundnut in inceptisols

Abstract

A study was undertaken at the RRS at Gayeshpur under New alluvial zone, in the Nadia district of West Bengal to investigate the effect of various geotextile management on crop productivity under pre kharif groundnut crop with four geotextile treatments. Geotextile material would be collect from locally and chopped with 4-5 cm length and spread before sowing. The yield of the crop was recorded as 51.54 q/ha, 46.92 q/ha. 42.03 q/ha and 31.09 q/ha respectively in jute geotextile (T1), coco coir geotextile (T2), vetiver root geotextile (T3) and farmer practice (T4) and the response over control due to each treatment were 20.45 q/ha (65.6%), 15.83 q/ha (50.91%) and 10.94 q/ha (35.18%) respectively in jute geotextile, coco coir geotextile and vetiver root geotextile. The results also reveals that bulk density of the soil decreased by 3.8%, 2.3% and 1.5% and porosity reversely increased by 4.6%, 2.0% and 0.8% respectively in jute geo textile, coco coir geotextile and vetiver root geo textile over control plot. Crops grown with jute geotextile content more organic matter (53.3%) than control plot. The water retention capacity is more throughout the growing seasons in jute geotextile.
