Performance of new Arboreum variety AKA-8 in relation to spacing and fertilizer levels

A field experiment was conducted during 2003–04 to 2005–06, to study the response of deshi cotton variety AKA-8 to spacing and fertilizer levels. Three years pooled data indicated that the seed cotton yield of deshi cotton variety (AKA-8) was significantly higher in closer spacing (60 × 15 cm) than wider spacing (60 × 30 cm). However, the higher values of growth and yield parameters in respect of dry matter accumulation, bolls plant⁻¹, and yield plant⁻¹ were observed in wider spacing as compared to closer spacing. Application of 100 per cent RDF (30:15:0 NPK kg ha⁻¹) recorded significantly higher seed cotton yield over control and application of 50 per cent RDF whereas differences with 150 per cent RDF was not found significant. Increasing trend was observed in growth parameters and yield attributs with increase in fertilizer levels.
