| dc.description.abstract | A field experiment was carried out during kharif 2021 on soybean (Glycine max L.) at the experimental farm of Department of Soil Science, COA, CSKHPKV, Palampur. The experiment comprised twelve treatments with four levels of phosphorus (0, 30, 60 and 90 kg P2O5 ha -1 ) and 3 levels of molybdenum (0,1.0 and 2.0 kg Mo ha-1 ), replicated thrice in a randomized block design to evaluate the effect of phosphorus and molybdenum application on soybean productivity and soil properties in an acid Alfisol. Application of 90 kg P2O5 ha-1 and 2.0 kg Mo ha-1 recorded better growth and yield attributes. The interaction was found to be significant on plant height, number of branches plant-1 , number of pods plant-1 , root volume, number of nodules plant-1 , nodule dry weight and was found to be non significant on number of leaves plant-1 , days to 50 % flowering, number of seeds pod-1 , test weight, root dry weight and root mass density. Application of 90 kg P2O5 ha-1 recorded significantly higher grain (24.8 q ha-1 ) and straw yield (39.4 q ha-1 ). Similarly, application of 2.0 kg Mo ha-1 recorded significantly higher grain yield (22.1 q ha -1 ), however no significant increase was seen in straw yield with increasing Mo application. Nutrient uptake (NPK and Mo) by soybean was enhanced with application of 90 kg P2O5 ha-1 and 2.0 kg Mo ha-1 . The interaction was found to be significant only in case of Mo uptake by grains. Application of 90 kg P2O5 ha-1 and 2.0 kg Mo ha-1 recorded higher protein content and protein yield respectively. Soil pH and organic carbon did not show any significant increase with varying P and Mo levels. Available NPK and Mo were significantly higher with application of 90 kg P2O5 ha-1 and 2.0 kg Mo ha-1 . The interaction effect was not significant on available NPK and Mo. Microbiological properties were also enhanced with application of 90 kg P2O5 ha-1 and 2.0 kg Mo ha-1 except urease activity which was not significant with increasing Mo levels. The interaction was found to be non signicant for all the microbiological properties. Highest cost of cultivation, B:C ratio, net returns and gross returns were registered with application of 90 kg P2O5 ha-1 along with 2.0 kg Mo ha-1 . From the present investigation it can be concluded that application of 90 kg P2O5 ha-1 and 2.0 kg Mo ha-1 to soybean crop was ideal for optimum higher grain yield and economic returns. | en_US |
