Study of physico-chemical properties of soil and availability of nutrients in maize-wheat cropping sequence

The present study was conducted to know the physico-chemical properties of soil and availability of nutrients. It was observed that physico-chemical properties of soil significantly influenced by various treatments. pH values varies from 8.18 to 8.30 during 2015-16 and 8.18 to 8.34 during 2016-17. It is evident from the data, the application of 150% NPK in treatment T11 significantly increases to 0.88 as compared to 0.84 under control plot). A critical perusal of data indicate that the highest organic carbon 0.92 and 0.97 per cent was obtained during 2015-16 and 2016-17, respectively with application of FYM 20 t ha-1 . The bulk density varies from 1.30 to 1.42 Mg m-3 and 1.26 to 1.41 Mg m-3 during 2015-16 and 2016-17 under different treatments. The significantly maximum water holding capacity was recorded (48.88, 49.00 and 48.94 %) with the application of FYM 20 t ha-1 (T12). The sand content of experimental plots ranged from 37.68 to 38.65 per cent with a mean value of 38.11. The highest available nitrogen 457 and 453 kg ha-1 , potassium 596 and 595 kg ha-1 , sulphur 23.76 and 23.68 mg ha-1 , DTPA extractable zinc 3.66 and 3.59 ppm, DTPA extractable iron 3.72, copper 2.52, 2.48 and 2.50 ppm was recorded by application of 100% NPK + FYM 10 t ha-1 (T9) treatments and manganese 13.52 and 13.36 ppm were recorded. | Study of physico-chemical properties of soil and availability of nutrients in maize-wheat cropping sequence
