Type: article
Abstract: This research aimed to study the effect of organic sources under different planting methods on the population of earthworm in sugarcane plantation for plant and ratoon crop. The experiment was conducted at Regional Agricultural Research station, Anakapalle (Andhra Pradesh) on sandy loan soils under split split plot design with different planting methods, soil health management practices and nutrient levels. The main plots consisted of three planting methods M1: conventional planting, M2: paired row planting, M3: dual row planting along with four organic amendments as sub plots (Control, trash mulching + biodecomposer (A & B), green manuring with sunnhemp @ 37.5 kg ha-1 seed rate, green manuring with sunnhemp @ 25 kg ha-1 seed rate followed by intercropping) and two nutrient levels as sub sub plots (75% RDF + NPK biofertilizers and 100% RDF). The results showed that in the plant and ratoon crop significantly highest earthworm population was observed with green manuring with sunnhemp @ 25 kg ha-1 seed rate followed by intercropping and was found significantly superior to control treatment. Organic sources can improve both the physicochemical and biological properties of the soil under these conditions, which cousld improve soil ecosystem services and thus increasing the earthworm population.
