Effect of cultural manipulations on growth and yield in tomato (Lycopersicon esculentum Mill.)

摘要

A field experiment was conducted to study the effect of cultural manipulations on growth and yield in tomato. Yield and its contributing characters were highest in November transplanted crop without topping and were lowest in March transplanting. Topping in both November and February transplanting reduced fruit yield, characters contributing to yield and incidence of fruit borer. The incidence of blotchy ripening and sun-scalding was highest in March transplanting and the lowest in November transplanting, whereas the reverse was true in case of incidence of fruit borer. Topping increased incidence of blotchy ripening, sun-scalding and decreased the incidence of fruit borer infestation in both November and February transplanting.
