Residue management of plant sugarcane and their effect on ratoon sugarcane under different fertilizer levels
Research Type
Departmental Research
Experiment Background
Sugarcane (Saccharum officinarum L.) is an important agro-industrial crop of tropical and sub-tropical regions of the world. It is one of the important cash crops in India, playing a pivotal role in the Indian economy as it contributes about 7.0% of the total annual agricultural revenue and also provides livelihood for 7.5 million sugarcane growers and their families. However, sugarcane productivity has been stagnant. In the present scenario, stagnation in cane productivity and deterioration in soil health are the major concern for its sustainability. The major reasons for its unsustainability are continuous mono-cropping, excessive use of fertilizers, intensive tillage, and depletion of soil biodiversity. Furthermore, open field burning of trash is also a common practice that results in the loss of organic carbon, plant nutrients, and soil biota, besides the environmental and health hazards due to the release of smoke and greenhouse gas emissions.
Alternatively, the retention of sugarcane trash in the field and placement of fertilizers in soil can improve the nutrient use efficiency, cane productivity, and soil quality in addition to reducing environmental pollution. Therefore, a multidimensional approach is essential to sustain sugarcane productivity with improvement in soil health and environment. In the last decades, many researches across the world have recommended the conservation agriculture as a solution to overcome the adverse effects of conventional practices on soil physical, chemical, and biological health of soil. The present study deals with conservation agriculture practices have the potential to improve soil health and cane productivity as well as reduce environmental pollution.
