Effect of cultivar and different plant spacing on yield and quality of cauliflower under Southern agro-climatic zone of Andhra Pradesh

Abstract

A field experiment was conducted to study the suitability of cauliflower (Brassica oleracea var. botrytis L.) cultivars with different plant densities for southern Agro climatic zone of Andhra Pradesh. The experiment was conducted with four cultivars and three spicing levels. The treatments were replicated thrice in two factorial randomized block design. Highly significant differences were observed among the cultivars, spacing levels and combined effect for yield and non- significant differences were observed for quality parameters, Among the cultivars Pusa Meghana recorded highest in all yield parameters viz., curd weight, curd diameter, CSI and yield per hectare whereas, spacing level, S2 (45 cm x 45 cm) recorded highest under all yield parameters. Among the interaction effects the cultivar Pusa Meghana with 45 cm x 45 cm spacing levels (V2S2) recorded highest in all yield parameters. Among the cultivars Pusa Meghana recorded highest TSS in S1 spacing, Pusa Karthiki recorded high total sugars in S2, Pusa Ashwini recorded high reducing sugars in S2 and Pusa Sharad recorded high ascorbic acid content in S1.
