 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of Swine Manure Extract by Foliar Application and Soil Drenching on Soil Chemical Properties and Variable Soil Strength of Cassava Planted Soils) ผู้เขียน:อุทัยวรรณ คันโธ, ดร.คณพล จุฑามณี, ศาสตราจารย์, นายยงยุทธ โอสถสภา, รองศาสตราจารย์, นางสุกัญญา จัตตุพรพงษ์, ดร.จงรักษ์ แก้วประสิทธิ์, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractThe effects were investigated of swine manure extract (SME) application on soil chemical properties and on soil strength, which are essential to soil management for cassava. The results of one cropping study revealed that an application of SME to the soil (SSME) or a combination of soil and foliar application of SME (FNSSME) tended to increase soil organic matter, cation exchange capacity and extractable Zn, but reduced soil strength. Nine split applications of SME in both the foliar or soil regimes had no effect on soil pH, but markedly reduced electrical conductivity indicating the depletion of soluble salts. FNSSME significantly decreased available P and exchangeable K while foliar application of SME decreased exchangeable K and exchangeable Mg. FNSSME significantly increased extractable Cu, and a similar result on extractable Mn was noted in the SME-treated soil. SME improved the availability of these two micronutrients. Chemical fertilizer (standard NPK) and FNSSME treatments reduced both exchangeable Ca and Mg. Soil strength calculated from penetration energy was maintained by a soil application of aqueous swine manure extract, SSME and FNSSME but not by an application of NPK fertilizer. The long term effects of SME application as a soil drench on the chemical properties of the soil and on soil strength over longer periods should be investigated. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Rice Seed Priming with Swine Manure Extract to Ameliorate Vigor and Nutrient Status of Seedlings) ผู้เขียน:อุทัยวรรณ คันโธ, ดร.คณพล จุฑามณี, ศาสตราจารย์, นายยงยุทธ โอสถสภา, รองศาสตราจารย์, Chai-arree, นางสุกัญญา จัตตุพรพงษ์ สื่อสิ่งพิมพ์:pdf AbstractSeed priming is one of the strategies for improving rice seedling development in an unfavorable environment. The effects of seed priming by concentrated swine manure extract (CSME) solution were evaluated on rice seedling vigor and nutrient status during the germination of aged and non-aged rice seed of the cultivar Pathum Thani 1 at the Suwanvajokkasikit Animal Research and Development Institute, Kasetsart University, Kamphaeng Saen Campus from March to August 2012. The CSME was diluted with water to ratios of 1:1, 1:2, 1:5, 1:25, 1:50, 1:100 and 1:200 volume to volume to make the tested CSME dilutions for the rice seed priming. The results showed that CSME seed priming significantly (P < 0.05) increased the vigor of rice seedlings, including the shoot and root length, fresh weight and dry weight at 21 d after sowing. Seed priming with a CSME dilution of 1:100 provided the optimal results for rice seedling improvement by significantly improving seedling vigor and the contents of P, Ca, Fe, Mn, B, Mo, Ni and Na in the rice seedlings when compared to the non-priming group. The results confirmed that CSME seed priming can enhance seedling vigor and the nutrient status of the rice seeds.

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effect of Swine Manure Extract by Foliar Application and Soil Drenching on Dry Matter and Nutrient Uptake of Cassava) ผู้เขียน:อุทัยวรรณ คันโธ, ดร.คณพล จุฑามณี, ศาสตราจารย์, นายยงยุทธ โอสถสภา, รองศาสตราจารย์, นางสุกัญญา จัตตุพรพงษ์, ดร.จงรักษ์ แก้วประสิทธิ์, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractSwine manure extract (SME) is the aqueous liquid obtained by steeping dried swine manure in water for 24 hr and contains plant nutrients. The objective of this study was to compare the effects of nine split applications of SME as foliar fertilizer (FSME) or soil fertilizer (SSME), as well as both soil and foliar fertilizer (FNSSME) and conventional NPK fertilizer (NPK) on the macronutrient and micronutrient uptake of the cassava cultivar Hauybong60. At harvest, 10 mth after planting, the combination of foliar and soil applications of SME favored dry matter and tuber yield improvement and tended to increase the macronutrient and micronutrient uptake by cassava plants. Cassava treated with FSME and NPK produced no signifi cant difference in total dry matter yield, fresh tuber yield or nutrient accumulation in the shoots. The combination of soil and foliar SME application was effective in promoting dry matter, tuber yield and the macronutrient and micronutrient uptake in cassava plants grown on slightly alkaline, loamy soil. |
