Effect of silicon and micronutrients on growth and yield attributes of sapota cv. Kalipatti under hill zone.

摘要

A field experiment was conducted at College of Horticulture, Mudigere to know the effect of silicon and micronutrients on growth and yield of sapota. Silicon source like potassium silicate as foliar application was given at concentration of 6 and 8 ml per litre and calcium silicate as soil application was applied only once at concentration of 1.0, 1.5, 2.0 and 2.5 kg per tree. Boron was applied at the concentration of 2 and 3 g per litre and micronutrients were applied at 3 and 4 ml per litre at monthly intervals. The maximum total leaf chlorophyll content (8.47 mg/g), maximum number of shoots (23.96), flowers (250.16), fruits per square metre (27.16), fruits per tree (1216.66), the highest yield per tree (124.81 kg), yield per hectare (12.48 t) and the minimum number of mummified fruits (34.00) were observed in treatment with foliar application of potassium silicate at 8 ml per litre.
