Interactive Effect of Phosphorus and Zinc on the Growth, Yield and Nutrient Uptake of Garlic (<i>Allium sativum</i> L.) Variety Gulabi
Keywords:Garlic, Phosphorus, Single Super Phosphate, Zinc, Zinc Sulphate.
The present study entitled â€œInteractive effect of phosphorus and zinc on the growth, yield and nutrient uptake of garlic (Allium sativum L.) var. Gulabi, was conducted at vegetable Research Farm Rawalakot, during the year 2013-14. Phosphorus was applied in the form of SSP (Single supper phosphate) while zinc was applied as zinc sulphate. Three levels of phosphorus 30, 50 and 70 kg ha-1 and three level of zinc i.e. 3 ppm, 4 ppm and 5 ppm were compared with control. The experiment was conducted in Randomized Complete Block Design (RCBD) with sixteen treatments and three replications with two factors. Minimum number of days to germination (18.567), maximum leaf length (40.96 cm) was found when phosphorus @ 50 kg ha-1 was used. Maximum plant height (67.500 cm), maximum number of leaves plant-1 (6.85), maximum dry weight of leaves (0.49 g), maximum weight of bulb (42.58 g), maximum bulb diameter (4.4 cm2), maximum numbers of cloves bulb-1 (8.500), maximum chlorophyll content of leaves ( 12.527 mg cm-2) and maximum average yield ha-1 (4549.6 kg) were observed in T11 (P @ 50 kg ha-1 & Zn @ 4 ppm ha-1).Â Maximum leaf area (93.93 cm2) and maximum fresh weight of leaves (2.88 g) was observed in T10 (P @ 50 kg ha-1 Zn @ 3 ppm ha-1). pH of extract and ascorbic acid showed non significant results for different levels of phosphorus and zinc.
