摘要
2018年秋季，班加罗尔农业科学大学甘地·克里希·维格纳·肯德拉(Gandhi Krishi Vignana Kendra)在全印度旱地农业协调研究项目(AICRPDA)进行了一项已有40年历史的试验，研究了Alfisols上的土壤宏量营养素。结果表明，连续施用化肥和粪肥可提高土壤微量元素有效性和谷子对土壤微量元素的吸收。长期综合养分管理表明，在T5 FYM @ 10 t ha + 100% RDF处理下，土壤有效氮值显著高于345.35 kg ha, P2O5含量为66.58 kg ha, K2O含量为136 kg ha。在不施肥的对照T1中，记录的数值较低。与100%氮磷钾处理和对照相比，施用FYM @ 10 t ha + 100% RDF的40年土壤中微量元素含量和谷子的养分吸收显著增加。
Long Term Effect of Integrated Nutrient Management on Soil Micronutrient Status in Finger Millet Mono-Cropping System
Soil macronutrients were studied on Alfisols with a 40-years old experiment at All India Co-ordinated Research Project for Dry land Agriculture (AICRPDA), Gandhi Krishi Vignana Kendra, University of Agricultural Sciences, Bengaluru, during kharif 2018. Results indicated that continuous application of chemical fertilizers and manures increased the micronutrient availability in soil and uptake by finger millet. Long term integrated nutrient management showed significant higher values of available N of 345.35 kg ha, P2O5 of 66.58 kg ha, K2O content of 136 kg ha, for soils in a treatment T5 FYM @ 10 t ha + 100% RDF. Lower values were recorded for the control T1 where no fertilizer was added. Similar trend of results were reported Nutrient content and nutrient uptake by finger millet for Application of FYM @ 10 t ha + 100% RDF over a period of 40 years significantly increased the macronutrient content in soil and uptake by finger millet as against 100% NPK treatment and control.
