| dc.description.abstract | The survey was conducted during May 2012 on available nitrogen and sulphur status of the soybean growing soils of Dharwad and Kalaghatagi taluks. A total of 100 samples were collected, the location of sampling point was recorded using GPS device. The processed samples were analyzed for available nitrogen and sulphur status. The study revealed that, of the total surveyed samples, majority of soils were low in available nitrogen sulphur in both the taluks and low (80 and 52% of samples) to medium (18 and 40% of samples) in available sulphur in Dharwad and Kalagatagi taluks respectively. Based on this information, a field experiment was conducted during kharif 2012 with treatments involving three levels of nitrogen and four levels of sulphur levels using soybean as a test crop. The effect of N and S levels on response of soybean revealed that, the significantly higher growth and yield attributes were recorded in the treatment receiving 40 kg N and 20 kg S ha-1 with highest B:C ratio (3.97). The optimum N:S ratio (10:6) and quality parameters, namely oil content (19.73% ), oil yield ( 460.15 kg ha-1 )and protein content ( 39.82% ) was highest in the same treatment receiving N 40 kg ha-1 and S 20 kg ha-1. Treatment receiving 40 kg N ha-1 and 20 kg S ha-1 also recorded the highest total uptake of N (227.56 kg ha-1), P (23.33 kg ha-1), K (55.11 kg ha-1) and S (14.70 kg ha-1) The highest residual N (231.00 kg ha-1) and S (14.23 kg ha-1) was found in the treatment receiving 50 kg N ha-1 and 40 kg S ha-1, however The highest available P (27.28 kg ha-1) was recorded in the treatment receiving 50 kg N ha-1 and 20 kg S ha-1 but effect was non significant. The highest available K (347.33 kg ha-1) was recorded in the treatment receiving 40 kg N ha-1 and 30 kg S ha-1. The treatment with 40 kg N ha-1 and 20 kg S ha-1 was found to be promising in increasing the soybean productivity and quality. | en_US |
