Abstract

Introduction: Since excessive use of fertilizers causes changes in soil pH and salt augmentation, it reduces soil fertility and bacterial activity (Pokorna, 1984), while use of manure increases soil microorganisms activity and results in the production of carbon dioxide, ammonium nitrate and simple acids in the soil (Patel & Patel, 1988). Biofertilizers that are beneficial microorganisms cause nitrogen fixation, release of phosphate ions, potassium, iron, etc., and will help the plants in the absorption of elements (Wu et al., 2005). Since the production process of medicinal plants is going to improve the quality, quantity and safety of their active substances, healthy nutrition plants by using bio-fertilizer and organic manure, are more compatible with this process. In this study, the effects of the application of organic fertilizers on yield and morphological index of roselle was studied.Materials and Methods: The experiment was conducted as split plot based on a randomized complete block design with three replications at the Agricultural Research Center of Zabol University, Iran during the growing season of 2011-2012. The treatments included three manure levels; 0, 10 and 20 t.h-1 and eight levels of bio-fertilizer such as control, NITROXIN, bio-sulfur, BIOLOGICAL PHOSPHORUS, NITROXIN+bio-sulfur, NITROXIN+BIOLOGICAL PHOSPHORUS, BIOSULFUR+ BIOLOGICAL PHOSPHORUS, NITROXIN+bio-sulfur+BIOLOGICAL PHOSPHORUS. Different levels of manure and biofertilizer inoculations were considered as main plots and subplots, respectively. Adding manure to the soil and seeds of roselle inoculation treatment was performed with bio-fertilizers before planting. Traits including plant height, stem diameter, number of lateral branches, number of fruits, ECONOMICAL YIELD, BIOLOGICAL YIELD, harvest index and morphological index of roselle were measured at the end of the growing season (November) when the fruits were at physiological maturity. The former measurements were statistically analyzed using SAS program version 1.1. Means were compared by using Duncan multiple range test at 0.05 level.Results and Discussion: Based on the results, levels of manure and bio-fertilizers and their interactions on biological traits were significant. The results showed that 10 t.h-1 manure+nitroxin consumption increased plant height and stem diameter by 24 percent compared with control (168.5 vs.135.4 cm and 13.3 vs.10.7 mm, respectively). The same results have been reported for fennel by Azzaz et al. (2009).10 t.h-1 manure+nitroxin treatment increased the number of fruits by 111 percent compared with the control treatment (36 vs.17 fruits per square meter). The highest number of lateral branches (8.3) was obtained in 10 t.h-1 manure+nitroxin treatment that shows an increase of 66 percent when compared with the control treatment (5.1). The highest ECONOMICAL YIELD (1.29t.ha-1) was shown in 10 t.h-1 manure+nitroxin treatment that indicates more than 300 percent increase in ECONOMICAL YIELD compared with the control treatment (0.3t.ha-1). The highest BIOLOGICAL YIELD (17.4t.ha-1) and harvest index (7.6 %) were obtained in 10 t.h-1 manure+nitroxin treatment. Farm yard manure is the most important source of energy and nutrients through improved physical, chemical and biological soil properties to increase the yield (Fallahi et al., 2009). Also use of bio-fertilizer includes NITROXIN that can produce vitamins, drivers of growth and root growth can accelerate the absorption of water and nutrients, and improve the number of branches of flowers, fruit and their BIOLOGICAL YIELD. These features increase the ECONOMICAL YIELD which is positively related to growth. These results are in agreement with the results of researchers (Sanches Govin et al., 2005). The results showed that the combined use of manure and bio-fertilizer, rather than taking them individually plays an effective role in increasing economic performance and growth characteristics of roselle.Acknowledgements: The authors are deeply grateful to the staff of the Zabol University and the Agricultural Research Center ofZabol University for their generous cooperation.
