Description |
A field experiment entitled “Effect of integrated nutrient management on soil properties, wheat (Triticum aestivum L.) yield and residual effect on pearl millet (Pennisetum glaucum L.) was carry out at Soil Science Research Farm, Chaudhary Charan Singh Haryana Agricultural University, Hisar during 2011-12 and 2012-13 to investigate the impact of different combinations of fertilizers with manure and bio-fertilizers (N fixing bacteria-Azotobacter and P solubilizing bacteria (Phosphobacterium) on wheat productivity, soil physico-chemical properties and to study their residual effect on the subsequent pearl millet crop. The experiment was laid out in split-split plot design with three replications comprising four levels of manure (control; 20 t ha-1 FYM; 10 t ha-1 FYM+10 t ha-1 vermicompost; and 20 t ha-1 vermicompost) in main plot; three levels of fertilizers (no NPK; 50% of recommended NPK and full (100%) recommended NPK) in sub plots and two levels of bio-fertilizes i.e., no inoculation and Azotobacter + phosphate solubilizing bacteria used as seed inoculants in sub-sub plots. Treatments were applied to wheat and the residual effects were studied on pearl millet. Results showed that, in wheat, significantly higher plant height, seeds/spike, 1000-seeds weight and effective tillers/m were registered in treatment VC20+NPK100 which was at par with FYM20+NPK100 for 1000-seed weight and plant height. Sole application of fertilizer gave at par results to VC20+NPK50 for plant height, effective tillers/m, seeds/spike and 1000-seed weight. Treatment VC20+NPK100, [VC10+FYM10]+NPK100 and FYM20+NPK100 were at par and gave significantly higher grain and straw yields of wheat over other treatments. Bio-fertilizer (Azo+PSB) significantly increased the yield attributing characteristics and the grain and straw yields of wheat. Uptakes of N, P and K by wheat were significantly varied with treatments and for a given level of manure, an increase in the level of NPK led to a significant increase in the content and uptake of these nutrients. Application of NPK100 without manure was at par with FYM20+NPK50. [VC10+FYM10] + NPK50 and VC20+NPK50 treatments for N and P uptake by the crop. Use of manure alone, whether as VC or FYM or their mix, was significantly inferior to the combined application of manure and NPK fertilizer for N, P and K content and uptake in wheat. Integration of manure, fertilizer and bio-fertilizer significantly improved the DTPA extractable micronutrients and their uptake by wheat. Bio-fertilizer use caused significantly higher total N, P, K and micronutrient uptake over the BF0. Soil pH and EC tended to decrease with the increase in organic carbon supply and lower values were recorded in FYM20 and NPK100 treatments while the higher were in FYM/VC0 and NPK0 treatment. Considering manure and NPK fertilizer, significantly higher available N, P and K and DTPA extractable micronutrients were obtained in VC20 and NPK100 treatments. Combined use manure and full fertilizer recommendations (FYM20+NPK100,[VC10+FYM10] + NPK100, and VC20+NPK100) showed significantly higher maximum soil moisture holding capacity (MSWHC), water stable soil aggregate (WSA) and hydraulic conductivity (HC). MSWHC, HC and WSA were lower in FYM/VC0+NPK100 while this treatment showed higher soil bulk density. Results on residual effect of INM applied in the preceding wheat to pearl millet showed that pearl millet grain and straw yields were significantly influenced by the residual effects of manure, fertilizer and bio-fertilizer and higher results were obtained in treatment FYM20, FYM10+VC10, and VC20. Considering manure and fertilizer, higher grain and straw yields were recorded in residuals of FYM10+VC10 and NPK100 and lower yields were recorded in FYM/VC0 and NPK0 treatment. Significantly higher available N, P and K and DTPA extractable Mn, Fe, Cu and Zn were recorded in plots that received 20 tons of manure in the preceding wheat while the lower values were found in FYM/VC0 treatment. The MSMHC, HC and WSA values were significantly improved due to the interaction effect of manure and fertilizer and higher percentage of MSMHC, HC and WSA were observed in FYM20+NPK100 treatment. |
