Aim: The present investigation entitled “Effect of nitrogen and spacing on flowering of spider lily (Hymenocallis littoralis L.)” was undertaken at College of Horticulture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli by considering the commercial importance of spider lily under Konkan agro-climatic conditions.
Methodology: The experiment was laid out in a split plot design using four levels of nitrogen and three levels of spacing with three replications along with the common dosage of phosphorous (150 kg ha-1) and potassium (100 kg ha-1).
Results: Flower yield and yield attributing characters viz., the highest number of flower buds per plant (46.84), flower buds per ha (16.01 lakh), flower yield per plot (8.50 kg) and flower yield per ha (6.56 t ha-1) were recorded with the treatment N1 (300 kg ha-1). With regards to spacing, the highest number of flower buds per plant (36.23), flower buds per ha (19.37 lakh), flower yield per plot (9.48 kg) and flower yield per ha (7.31 t ha-1) was recorded in S3 (30 × 60 cm). However, the interaction effect of treatment combination N1S3 (300 kg N ha-1 ; 30 × 60 cm) recorded the highest number of flower buds per plant (58.52), flower buds per ha (29.49 lakh), flower yield per plot (16.06 kg) and flower yield per ha (12.39 t ha-1).
Interpretation: The observations were recorded on various flowering parameters namely number of flower buds per plant, flower buds per ha (lakh ha-1), flower yield per plot (kg plot-1) and flower yield per ha (t ha-1) and most of the parameters were differed significantly at highest levels of nitrogen and spacing.
