Abstract
A field experiment was conducted during winter season of 2015-16 to study 'Studies Effect of Planting Dates and Varieties on Growth and Quality on Gladiolus (Gladiolus hybridus Hort.) under sub-humid zone of Rajasthan' having 15 treatment combinations of five Varieties (V1- African Star, V2- Hunting Song, V3- Legend, V4- Pusa Srijana and V5- Snow Princess) and three planting dates (D1- 10th October, D2- 25th October and D3- 9th November). The treatment V2D1 (Hunting Song + 10th October planting) recorded the maximum plant height (116.10 cm), highest number of leaves per plant (8.77), main stem diameter (1.50 cm), number of florets per spike (15.8), spike length (91.80 cm), rachis length (57.90 cm), floret diameter (10.04 cm), vase life of spike (13 days), While the maximum leaf length (64.20 cm), leaf width (4.96 cm) in (V5D3) and maximum spike girth (0.91cm) was found in (V1D2). The growth and flowering quality was found superior in compare to other planting dates.
Highlights
Present research efforts aim at standardization of planting date and suitability of varieties for local climate and edaphic conditions of the sub-humid zone of Rajasthan
The growth and yield of gladiolus like other plants depend upon planting time e.g., number of florets/spike, spike length, floret diameter, floret length was best with October planting [2]
Gladiolus is very rich in its varietal wealth and every year there is an addition of new varieties; varietal evaluation becomes necessary to find out suitable variety for a particular region
Summary
In gladiolus the most common method of improvement is through hybridization. Like all other economical plants, the growth and development of gladiolus is governed by its genetic makeup and environmental factors of the growing region and various management practices. Date of planting plays an important role in regulating growth and quality of gladiolus. Vegetative growth and quality of gladiolus is improved by proper planting times which satisfy the consumer's demands [1]. The timing of flowering from various planting dates is quite predictable under ideal environmental conditions. The growth and yield of gladiolus like other plants depend upon planting time e.g., number of florets/spike, spike length, floret diameter, floret length was best with October planting [2].
