Dr. Y.S.R. Horticultural University, All India Co-ordinated Research Project on cashew, Cashew Research Station, Bapatla, Andhra Pradesh
A field experiment was conducted at AICRP on Cashew, Cashew Research Station, Dr.YSR Horticultural University Bapatla in Andhra Pradesh. To study the effect of different plant densities with different levels of fertilizers on growth and yield of cashew variety BPP-8 (H2/16). The experiment was laid out in a split plot design with three planting densities (10 x 5 m2, 200 plants ha -1), 6 x 4 m2 (400 plants ha-1) and 5 x 4 m2 (500 plants ha-1) along with three levels of fertilizer (75:25:25, 150:150:50 and 225:75:75 NPK kg ha -1) replicated four times. The results revealed that adoption of high density planting systems with different levels of fertilizers, the maximum plant height (5.55 m) and canopy surface area (79.96 m2) was recorded in at a spacing of 10 X 5 m2 with a fertilizer dose of M 75:25:25 NPK kg ha-1. The maximum flowering intensity was recorded in S M (16.83 and 10 X 5 m2). The maximum number of nuts per panicle was recorded in S M (3.82) with a fertilizer dose of M (3.46). The annual nut yield per
tree was highest in S (10.69 kg per tree) with a fertilizer dose of M (150:50:50) and cumulative nut yield also highest in the same treatment S M (51.78 kg ha-1).
