Title : Mechanical transplanting of rice for reducing water, energy, and labor footprints with improved rice yields in the Tropics

Abstract :

Traditional rice transplanting is water, energy, labor, and capital-intensive, causing sustainability challenges like diminishing subsurface water table, soil health, and escalating greenhouse gas emissions that contribute to global warming. Labor shortages during transplanting occur due to agricultural workers moving to cities for better pay. Low plant density under the traditional transplanting method forces farmers to use more inputs viz. fertilizers and pesticides, which raises cultivation costs and lowers grain output. Under these conditions, rice transplanting must be cheap and labor-saving without compromising potential grain yield. Mechanical transplanting of rice (MTR) improves crop production and ensures timely transplanting. Mechanical rice transplanting is profitable and simple. Due to high initial investment and low awareness of growing mat-type nurseries, field acceptance is low despite its superiority over conventional transplanting. Technical talent, timely availability, and tailored employment may help farmers adopt mechanized transplanting. MTR is a promising, sustainable, and climate-smart technique to promptly transplant rice seedlings in texturally dissimilar soils, which reduced the labor and energy footprints with reduced greenhouse emissions, and higher rice land productivity, profitability, and sustainability. This review examined the pros and cons of mechanical transplanting on rice productivity and profitability after identifying the gaps that need to be filled for its better adoption.
