QUALITATIVE AND QUANTATIVE PARAMETERS OF SUGARCANE CROP UNDER DIFFERENT SOURCES OF FERTILIZERS

Abstract

The field study was conducted to evaluate the effect of different fertilizer sources on the growth, cane yield and quality parameters of sugarcane at Sugarcane Section, Agriculture Research Institute, Tandojam during the year 2003-2004. The treatments included four different sources of crop fertilization i.e. T1= NPK @ 225-112-168 kg ha-1 , T2= EM prepared material, T3=FYM @ 25 t ha-1 and T4=Press mud @ 25 t ha-1 . The results revealed that chemical source of fertilizer (NPK) at the rate of 225-112-168 kg ha-1 proved to be more effective to produce significantly. The sugarcane crop when fertilized with 225-112-168 NPK kg ha-1 , it produced better germination (62.15%), more cane length (211.3 cm), better cane girth (2.61 cm), satisfactory tiller production (6.50 per stool), maximum cane yield (89.35 t ha-1 ), brix (20.41%) and sugar recovery (10.38%). EM prepared material ranked second and produced germination 58.06%, cane length 181.3 cm, cane girth 2.34 cm, number of tillers 5.56 per stool, cane yield 74.53 t ha-1 , brix 20.31% and sugar recovery 10.31%. The crop when fertilized with FYM @ 25 t ha-1 , it produced germination 56.88%, cane length 158.8 cm, cane girth 2.21 cm, number of tillers 5.38 per stool, cane yield 68.96 t ha-1 , brix 20.51% and sugar recovery 10.20%. The sugarcane when received fertilizer in the form of Press mud @ 25 t ha-1 , it produced germination 56.06%, cane length 157.5 cm, cane girth 2.19 cm, number of tillers 5.19 per stool, cane yield 64.96 t ha-1 , brix 20.14 percent and sugar recovery 10.15%. It was observed that NPK source of fertilizers was more effective for almost all the quantitative and qualitative characters studied as compared to EM prepared material, FYM and Press mud.
