CORRELATION STUDY BETWEEN SOIL CHEMICAL PROPERTIES AND JUICE QUALITY OF SUGARCANE AS INFLUENCE BY SALT AFFECTED SOILS OF MULA COMMANDA.V. Mavchi, A.D. Kadlag and D.B. Ahire
The sugarcane productivity and total production of cane decreases due to problem of salinity and alkalinity of soil condition. In Maharashtra, the area of sugarcane track is either saline /sodic, this might be one of the reason of declining cane yield. Due to faulty water management, canal irrigation and seepage, chemical fertilizer deterioration of land through salinity and alkalinity. The area affected due to salinization in Maharashtra is about 0.534 million ha. In such situation to meet the sugar requirement from the production of existing acreage is difficult, because little scope for increasing the area under sugarcane due to limitations of land and irrigation facilities. Hence, attention has to be paid towards maximizing cane production per unit area per unit time. The present investigation was under taken to study correlation between soil chemical properties and juice quality of sugarcane as influenced by salt affected soils of Mula command area. The organic carbon content of salt affected soil showed significantly positive correlation with pH (+0.566**). The commercial cane sugar and organic carbon showed significant positive correlation (+0.391*). The manganese content of salt affected soil showed significant positive correlation with brix (+0.572**). However, it was significantly negative with purity (-0.573 **) and commercial cane sugar (-0.444*). The purity and commercial cane sugar content of salt affected soils were highly significantly negatively correlated with brix (-0.858** and 0.730**) and vice versa with sucrose (+0.673 ** and +0.583**). The purity of sugarcane juice was positively highly significant with commercial cane sugar (+0.800**).
