摘要

A field experiment with integrated nutrient management by organic and inorganic fertilizers on sugarcane-ratoon system for two cycles was conducted at Agricultural Research Station, Kota. The experimental crop was planted on February 25, 2005, ratooning initiated on January 20, 2006 and ratooning of plant crop during 2006-07 was initiated on January 30, 2007 to study the influence of integrated use of organic sources with different levels of mineral nutrition, biofertilizer and biopesticides in plant and ratoon crop, respectively. It was comprised of five treatments. Results revealed that treatment consisting of organic and inorganic fertilizer (T5) significantly produced higher plant and ratoon cane yield over T2 and T3 treatments. There was a drastic decrease in cane growth when resulted to mineral nutrition (T1). The treatment T5 having combination of 75% recommended NPK through inorganic+25% through organic fertilizer ((FYM)+biofertilizer and biopesticides) showed higher net monetary return, higher uptake of NPK and higher sugar yield compared to T1 treatment (recommended NPK+micronutrient through inorganics) in plant and ratoon crop. There was a slight reduction in soil pH and increase in electrical conductivity with the application of organic manure. At the end of plant and ratoon crop, the significant increase in available N and K was recorded with the application of T5 treatment over T1 and T4 treatments, whereas T5 treatment was significantly superior over T1 and T2 with respect to available P.
