Effect of different levels of fertigation on growth and yield of custard apple

Abstract

An investigation entitled “Effect of different levels of fertigation on growth and yield of custard apple” was carried out at Central Research Station during two consecutive years 2021-22 and 2022-23 on five-year old custard apple plants cv. Balanagar. The experiment was conducted to evaluate the effect of different levels of fertigation on growth and yield parameters, and to find out the optimum fertigation level custard apple. The experiment was laid out in Randomized Block Design with eleven treatments. The results indicated that, growth was significantly influenced by different fertigation levels. The maximum growth viz., number of shoots per branch, leaf area and minimum days required for emergence of new shoot was observed with the application of 180-108-216 NPK kg ha-1 through fertigation while, the number of leaves per shoot and leaf area was recorded maximum with the application of 203-122-144 NPK kg ha-1 through fertigation. The maximum fruit yield (kg per plant and tons per ha) was observed with the application of 180-108-216 NPK kg ha-1 through fertigation.
