Description A nutritional survey of~sweet orange orchards was
conducted during 1987 with an. object to find out the
nutrient status and quality of sweet orange grown in
nayalaseema region of Andbra Pradesh.
The soils of the above orchards were sandy loam
to clay in texture, aligbtly to strongly alkaline in soil
reaction, low to medium in avai~able N, low to high in
available P2 o~ and medium in available K2o. In all the
soils the available ()1, Mn and Fe were above the critical
limits. zn was below the critical limit in rnost of the
soils.
The available N content of soil was positively
correlated with yield (number and weight of fruits)
percentage of juice, TSS, tot a 1 sugars and reducing
sugars and negatively correlated with vitamin C content
of juice, while soil vH was negatively correlatAd with
reducing sugar content of tn1it juice. soil available
P205 was positively correlated with reducing sugar content
of fruit juice.
Tbe sweet orange grown on Inceptisols which are
having greater depth, more gravel content, rich in
nutrient status of soil and which received more quantity
. of nitrogen fertilizers gave higher yield (number and
weight of fruits) and produced better quality fruits
compared to that of sweet orange grown on Alfisols and
vertisols.
sathgudi performed well in terms of yield (number
and weight of fruits) and fruit quality. Among different
locations under each soil type sweet orange grown on
Alfisol of Kothur, Vertisol of Polur and Inceptisol of
C!lapalavaripalli showed higher yield (number and weight
of fruits) and better fruit quality in terms of percentage
of juice, fruit weight, TS~, total sugars and
reducing sugar content of fruit juice.
'.rhe fruit yield (number and lfeight of fruits) was
positively correlated with leaf Nand P during all the
periods of leaf sampling in all the soils.
To conclude, there were variations between the
cultivars and among different soils and locations with
respect to yield and quality of sweet orange fruit.
Raising orchards on soils which are deep and contain
sufficient (5-30%) gravel with high available nutrien~
will improve the yield and quality of ftuit. sathgudi
is the best cultivar under Rayalaseema conditions to
get maximum yield aDd better quality fruits
