摘要

Sugarcane ratoon crops is common in India but with low productivity. To overcome this, various cultural operations such as cutting of old roots (off-barring), stubbles shaving, inter-cultivation between rows for weed control, gap filling, placement of fertilizers, etc. have been recommended. The traditional cultural practices, tilling and mixing of broadcast fertilizer in ratoon crop are insufficient for proper soil management and nutrient utilization. An innovative machine named as 'Deep Soil Volume Loosener-cum-Fertilizer Applicator' has been developed for performing recommended cultural practices in ratoon crops such as deep tilling of soil up to a depth of 300 mm within the rows, cutting of old roots, deep placement of fertilizer at 200 ± 50 mm depths in the moist root zone, breaking of clods and consolidation of tilled soil for moisture conservation with improved traction of power unit. The developed machine is pulled by 40-45 kW tractor and leaves the tilled surface completely levelled after operation, thus making it an efficient machine for soil cultivation in laser levelled fields. The field performance evaluation of this machine in comparison to conventional practice of ratoon management with row crop rigid tines cultivator have shown significant increase in crop growth parameters, yield attributes, juice analysis and cane yield increase of over 30.7 % and has created great demand amongst sugarcane growers.
