Effect of Organic Manures and Inorganic Fertilizers on Yield, Quality of Sugarcane and Soil Health in the Long Term Manurial Experiment
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2019, Vol 9, Issue 4
Abstract
Imbalance in the use of organic manures and fertilizers has lead to deleterious effect on soil productivity, yield and quality of sugarcane. A permanent manurial experiment was carried out at Sugarcane Research Station, Cuddalore, Tamil Nadu to evaluate the long term effect of manures and fertilizers on yield and quality of sugarcane in the north eastern region of Tamil Nadu. The 21st plant crop of CoC 671 was evaluated in the permanent manurial experiment with eight main and six sub plot treatments replicated twice in a split plot design. The results of the statistical analysis of cane yield revealed that 21st plant crop of CoC 671 was significantly increased to 84.30 t ha-1 due to the soil application of nitrogen @ 350 kg ha-1+ as neem cake blended urea in combination with recommended dose of P &K and compost. The CCS per cent was also significantly increased due to the various levels of nitrogen in combination with recommended dose of P, K and compost. The evaluation of soil pH and EC as influenced by long term application of various levels of nitrogen in combination with P, K and compost did not vary widely. The available nitrogen status of the soil was significantly increased due to the soil application of various levels of nitrogen in combination with P, K and compost. The organic carbon content of the soil as influenced by the soil application of P, K and compost as well as various levels of nitrogen was found to be significant.
