Effect of diatomaceous earth on crop duration and yield of guava cv. Sardar

Abstract

A field experiment was carried out to know the response of soil application of diatomaceous earth as a source of silicon on crop duration and yield of guava cv.

With respect to total crop duration, treatment heaving RDF + 3 kg/plant of DE has took less number of days (21.73 days), while delayed harvesting was noticed in the treatment control. Maximum total number of flowers and yield per hectare (14.53 t/ha) was recorded in RDF + 3 kg/plant of DE while minimum total number of flowers and yield per hectare was recorded in Absolute control.
