Abstract

A pragmatic study was contrived to ascertain the effect of different rates of NPK fertilizers on the growth and yield of Sapota during the year 2012-13 at a private farmhouse located at south-east of Gharo, Sindh – Pakistan. The fruit yield per plant (kg/plant) was found maximum in those plants which are treated with T₇. For the same treatment  number of fruit (1506.557), length of fruit (4.186 cm), breadth of fruit (5.050 cm), volume of fruit (112.512 cc), weight of fruit (120.835 gm), pulp weight (97.594 gm), peel weight (22.080 gm) and yield per plant (189.629 kg/plant) was recorded maximum. Same treatment also showed the superior fruit quality traits evaluated in terms of maximum total soluble solids and total sugar was (22.234 ^oB) and (17.309%) with minimum acidity of (0.048%). However, control plants showed un-satisfactory results regarding all the parameters. Amongst the various NPK treatments T₇ was observed to be more suitable and economical dose therefore, application of fertilizers beyond this level will be an uneconomical and wasteful practice.
