Effect of different sources and levels of S on growth and yield of garlic (Allium sativum L.). (120)

The investigation was undertaken during winter seasons of two consecutive years, i.e., 2002-2003 and 2003- 2004 at the Horticultural Research Station, in the gangetic alluvial region of lndia, to study the growth and yield of garlic (Allium sativum L.) as influenced by different levels and sources of S. The experiment was laid out in a randomized block design with SSP, elemental S, K2SO4, and nitrosulf in two concentrations, 500 mL 100 L-1 ha-1 and 625 mL 100 L-1 ha-1. It was observed that the height of the plant, basal girth, and total number of leaves per plant were maximum with application of S @ 60 kg ha-1in SSP form and with nitrosulf @ 500 mL 100 L-1 ha-1, had a significant effect on plant height, leaf number, and basal girth compared to other treatments in both the years. An almost similar trend was observed with respect to bulb width, bulb length, bulb weight, clove number per bulb, clove diameter, and clove weight. However, the highest bulb yield of 6.24 t ha-1 (mean of two years) was obtained with nitrosulf @ 500 mL 100 L-1 ha-1, which caused 41.18% yield increment over the control of 4.42 t ha-1 (mean value), followed by SSP @ 60 kg Sha-1. The garlic yield was also correlated positively with all the yield and growth components, viz., number of cloves per bulb, bulb width, bulb length, bulb weight, and basal girth of plant in both the years.
