Standardization of spacing and fertigation in marigold genotypes for northern dry zone of Karnataka

Abstract

The present investigation was aimed to evaluate and commercialize different African marigold (Tagetes erecta L.) genotypes for UKP command area of Karnataka. The study was also aimed to standardize optimum spacing and fertigation levels for promising genotypes during kharif and summer seasons 2015-18 at College of Agriculture, Bheemarayanagudi of Shahapur taluk, Yadgir district. Among the fertigation schedules, providing 100 per cent water soluble fertilizers (125:60:60 NPK kg ha-1) resulted in significantly higher flower yield (38.21 t and 34.24 t ha-1), higher flower diameter (7.01 and 6.43cm), more duration of flowering (123.11 and 112.88 days) and gave higher benefit cost ratio as compared to other treatment combinations during kharif and summer season respectively.
