Alleviating the adverse effects of water limitation on Basil (Ocimum basillicum L.) physiological traits and yield, by exogenous application of Biofertilizers
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2016, Vol 9, Issue 1
Abstract
In order to investigate the effects of plant growth promoting rhizobacteria on some physiological traits of Basil (Ocimum basillicum L.) under water deficit stress, a factorial experiment was carried out in 2015. The first factor was soil water content [100% of field capacity; 60 % of field capacity and 40% of field capacity]; And the second factor was biofertilizer consisting of [Pseudomonas koreensis and Pseudomonas vancouverensis as potassium releasing bacteria; Pseudomonas putida and Bacillus lentus as phosphorus releasing bacteria; Azetobacter strains as nitrogen fixing bacteria; Combination of potassium and phosphorus releasing bacteria; Combination of potassium releasing and nitrogen fixing bacteria; Combination of nitrogen fixing bacteria and phosphorus releasing bacteria; Combination of the three kinds of bacteria; Chemical Fertilizer based on soil analysis as positive control; and No fertilizer as negative control]. Results showed that water deficit increased essential oil, proline and total soluble carbohydrates content. Whereas, chlorophyll a, chlorophyll b, carotenoid and shoot yield decreased. Application of biofertilizers improved these traits under water stress condition as well as normal irrigation. Applying combination of 3 biofertilizers led to 10.82% shoot yield increase in comparison with negative control under sever water limitation. These findings indicated that biofertilizers application can be recommended for profitable basil production under water limitation condition.
