Description A field experiment, “Effect of planting time and plant densities on growth, yield and quality of garlic (Allium sativum L.) Cv. Jamnagar” was conducted at Model Orchard, College of Horticulture, Dr.Y.S.R. Horticulture University, Rajendranagar, Hyderabad during the year 2011-12.The experiment was laid in split plot design comprising two factors viz., Different planting dates and plant densities. Entire treatments were replicated three times.
The treatment combinations include four different planting dates viz., 1st November (D1), 15th November (D2), 1st December (D3) and 15th December (D4) and six plant densities viz., 10 x 5 cm (900 plants/plot) (S1), 15 x 5 cm (600 plants/plot) (S2), 20 x 5 cm (450 plants/plot) (S3), 10 x 7.5 cm (600 plants/plot) (S4), 15 x 7.5 cm (400 plants/plot) (S5) and 20 x 7.5 cm (300 plants/plot) (S6). Five plants were selected at random from each treatment and tagged for recording biometric observations. The data were recorded at an interval of 30, 60, 90, and 120 DAP for assessing parameters like per cent germination, plant height, plant girth, fresh weight of leaves, dry matter production of whole plant, leaf area, leaf area index, crop growth rate, bulb weight, bulb girth, number of cloves for bulb, yield and different quality parameters.
The results emanated from the experiment revealed that, amongst the four different planting dates, early planted crop on 1st November (D1) recorded maximum per cent germination, plant height, plant girth, fresh weight, dry matter production, bulb weight, bulb girth, clove size, number of cloves per bulb and yield and quality parameters and minimum was observed in late planted crop on 15th December (D4). Amongst the plant densities, lower plant density with 20 x 7.5 cm (300 plants/plot) (S6) resulted in best performance of the all parameters except the yield. Maximum yield was recorded with higher plant density with 10 x 5 cm (900 plants/plot) (S1).
The present investigation conducted under Hyderabad conditions has revealed that planting on 1st November with plant density of 300 plants/plot with spacing of 20 x 7.5 cm resulted maximum in all the parameters including B:C ratio (0.54:1). But maximum yield was recorded with planting on 1st November with higher plant density of 900 plants/plot with spacing of 10 x 5 cm.
