To Study the Effect of Different Soil Depth and Leaf Nutrient Status in Relation to Yield and Physiological Fruit Quality of Sweet Orange of Jalna District of Maharashtra

Abstract

The present investigation was carried out to study the effect of different newlinesoil depth and leaf nutrient status in relation to yield and physiological fruit quality of newlinesweet orange of Jalna District of Maharashtra. Representative soil, leaf and fruit samples newlinewere collected randomly from orchard located in different talukas of Jalna district during newlineyear 2014-2016. newlineThree soil samples were collected from each orchard during May 2014. Below newlinethe tree canopy at 0-30, 0-60 and 0-90 cm depth. So in all 30 samples were collected newlinewithin tree canopy at 0.5 m away from the tree trunk. newlineThe leaf samples were collected from second; third or fourth leaf from non newlinefruiting branches of randomly selected five trees from each orchard. Facing all four newlinedirections (East, West, North and South) at height of 1.5 to 1.8 m. from ground level at newlineeach sampling hundred leaves were collected from the four to six month old twig of mrig newlineflush. newlineThe ninety uniform matured fruits were collected from each orchard newlineduring November December 2014. Washed 2-3 times with fresh water and brought to newlinethe laboratory for analysis. newlineThere were significant differences in respect of soil nutrients, leaf nutrient newlinestatus, yield and quality of fruits among the orchards studied. newlineMaximum number of fruits and weight of fruits is more in 0-90 cm depth of newlinesoil and minimum in 0-30 cm depth of soil. newlineIn 0-90 cm depth of soil weight of fruit, fruit girth, juice content, TSS, ascorbic newlineacid, reducing sugar, non reducing sugar is more in all samples. In 0-30 cm depth of soil newlineall category are minimum. But in acidity content is more in 0-30 cm and low in 0-90 cm newlinedepth of soil. newline
