An experiment was carried out at the farm of Annamalai University during summer 2006 to investigate the effect of different liquid biofertilizer on the nutrient content and uptake by okra. Symbion N and P were liquid formulation of Azospirillum and phosphobacter, respectively, supplied by T. Stanes and Co., Pvt. Ltd. The experimental results revealed that soil application of both Symbion N and Symbion P significantly increased the nutrient content and uptake by okra besides improving the yield.Keywords

A field experiment was conducted to evaluate the effect of liquid biofertilizer Symbion N (Azospirillum) and Symbion P (Phosphobacter) on the growth and yield of okra. The experiment was laid out in Annamalai University experimental farm in clay loam soil during summer 2006. The treatments studied were T1-Symbion N (foliar), T2-Symbion P (soil), T3-Symbion-N (foliar)+Symbion P (soil), T4-Symbion N+Symbion P (soil) and T5-control. All the treatments were replicated three times in RBD. A fertilizer schedule of 40:50:30 kg N:P2O5:K2O/ha was applied to all the treatments. The foliar application of Symbion N was followed @ 250 ml/ha and sprayed at 10 days after sowing and another at flowering. The soil application of liquid formulations was carried out @ 250 ml/ha applied one at 10 days after sowing and another at flowering. Okra variety Parbani Kranti was sown as test crop. The results of the study indicated that application of liquid bio-fertilizer both Symbion N and Symbion P significantly increased the growth character, yield character and yield of okra. Among various treatments, Symbion N and Symbion P both applied in soil was significantly superior in increasing the growth and yield of okra. This treatment recorded the highest okra yield of 6280 Kg ha-1.Keywords

In an incubation experiment, the changes in physio-chemical properties and the periodical release of nutrients with fortified organic manures to a coastal saline sodic soil was studied. The experimental soil was collected from the farmer’s field at Sillankuppam village, Cuddalore district. The FeSO4+ZnSO4 fortified green leaf manure and coir pith significantly exerted a favourable effect on reducing the salinity and sodicity and increasing the availability of major and micronutrients in soil. Among the organics, micronutrients fortified green manure was associated with the greatest improvement in physio-chemical properties and nutrient availability.Keywords

A pot experiment was conducted at the Department of Soil Science and Agriculture Chemistry, Annamalai University, Tamilnadu during 2008-2009 to study the fertilizer requirement of Catharanthus roseus in coastal sandy soil. The soil was classified as typic Udipsaments and had deficient level of N, P and K. The growth parameters of Catharanthus rose us viz., plant height, number of branches per plant, number of leaves per plant were influenced favorably with increasing level of NPK application. A reduction in NPK application reduced the yield parameters and leaf yield significantly. The result revealed that the application of NPK @ 30: 40: 40 kg ha-l proved to be optimum as it recorded the maximum growth characters like plant height (97.50 cm), number of branches per plant (10.75) and dry weight of leaves (24.54 g/plant) and dry weight of ischolar_main (8.46 g/plant).Keywords
