Description A study was conducted during July 2004 to May 2005 to
ascertain the nutritional status of twenty sweet orange orchards Cv.
Sathgudi in ten different mandals of Prakasam district local agroclimatic
conditions.
The soil nutrient status of all ten locations of sweet orange
orchards under study were alkaline in reaction and free from the
presence of salts. The available N, P were found to be low to
medium, while K was medium to high, while deficient to sufficient in
Ca, Mg, Fe, Zn and other elements S, Mn and Cu were sufficient.
The soil nutrient status before and after conduct of experiment
rev ealed that nutrient content at surface level of the soil is more,
and showed a static or a decline in its content at lower depths.
With regard to leaf nutrient content, maximum leaf N content
was observed in the months of July, November P in the months of
September and July K in the months of January and March, Ca in
the months of September and January, Mg in the months of July and
September, S in the months of January and July, Fe in the months of
January and July, Mn in the months of January and November, Zn in
the months of July and September and Cu in the months of January
and July.
Between fruiting and non-fruiting terminals, the leaf
nutrients N, P, K, Ca, S, Mn and Zn were higher level in non-fruiting
terminals and Cu in fruiting terminals during the entire study period
howev er Mg, found to be higher in non-fruiting terminals during the
period May, July and September while, Fe found to be higher in nonfruiting
terminals during the period July, March and May. In general
Konakanamitta mandal orchards recorded relatively higher nutrient
content. In the present study, plant growth characters viz., plant
height, plant spread, fruit characteristics viz., fruit volume, diameter
and weight, yield (number of fruits per tree), fruit quality parameters
viz., TSS, acidity, skin thickness and number of segments per fruit,
the respectively maximum values were recorded by Konakanamitta
mandal orchards followed by Yer ragondapalem mandal sweet
orange orchards.
