Diatomite and Rice Husk Biochar as Silicon Source and its Effect on Yield of Wetland Rice
2018
Nagabovanalli B. Prakash, Kollalu Sandhya
Field experiments were carried out during summer and kharif of 2015 and kharif of 2016 with and withoutapplication of silicon (Si) under rice cropped and non-cropped condition. Diatomite and rice husk biocharwas used as Si source and applied @ 300 kg ha-1 and 2 t ha-1, respectively. The continual application of Siincreased the straw and grain yield consistently compared to control. Straw and grain Si content and itsuptake also increased with application of Si but not significantly differed. Treatment under the croppingsituation recorded higher soil pH. Although, there was no significant difference in electrical conductivity(EC) among the treatments, post-harvest soils recorded higher values than initial soil. Plant available Sicontent in post-harvest soil was significantly higher in control where no crop was grown with or withoutadded Si. However, in the presence of rice crop, soil Si content decreased and/or was on par with the othertreatments.
