Brassinosteroids are the plant hormone reported to alleviate heat stress. This study investigated the response of rice (Oryza sativa L.cv. Pathum Thani 1) to 24-epibrassinolide (EBR) or 7,8-dihydro-8-20-hydroxyecdysone (DHECD) under high temperature by examine photosynthesis performance and yield. The results show that foliar application of 0.01 μM EBR and 0.1 μM DHECD on V7 vegetative growth could increase the photosynthetic efficiency under 40/30 ºC (day/night temperature). In field growth experiment, the application of those brassinosteroids concentrations on V7 growth stage could increase seed setting in all panicle part and number of normal seeds per particle. The results indicated that EBR and DHECD alleviated heat stress of rice ‘Pathum Thani 1’ by...

ผลของวัสดุอินทรีย์และระบบการไม่ไถพรวนต่อการเปลี่ยนแปลงสมบัติทางเคมีของดินในนาข้าว Thai Agricultural
Puthipol Sirimool; Wimonan Kanket; Pornthip Srimongkol; Supasith Sithapanich.
Thailand is a country located on the tropical agriculture. Natural soil fertility is low. Low organic matter content. Due to the rapid degradation of the heat and humidity. Therefore,the concept adding of organic material and reduced tillage to improve soil properties for the better. The study on the effects of tillage systems on changes in soil chemical properties of rice. The experimental design was Randomize Complete Block Design (RCBD) 5 treatments. 1) tillage (control) 2) tillage with sunnhemp incorporation 3) tillage with rice straw incorporation 4) no tillage with sunn hemp mulching 5) no tillage with rice straw mulching. Soil samples were collected during the period, before transplant and 2 weeks after harvest. The soil reaction, electrical...

The development of a water saving rice growing system was stemmed from an attempt to manage efficient water usage, whereby reducing level of water use but still maintaining acceptable level of yield. To be successful in implementing the water saving rice growing system, it is necessary to understand a suitable photosynthetic mechanism and photosynthetic efficiency of each rice cultivar to be grown in such system. An understanding of such knowledge will lead to a better selection of healthy and high yielding cultivars. As such, this study was aimed to compare responses of 10 Thai rice cultivars in terms of photosynthesis rate and growth in well-drained and water-logged systems. Our data indicated that almost all rice cultivars grown under either...

Rice growth and yield are adversely affected by soil salinity. The application of organic matter is a successful technique for saline soil remediation. The experiment was conducted to determine the effect of different organic materials on the response of rice in saline soil. Experimental design was a randomized complete block with 4 replicates comprised 4 treatments: 1) no organic material application (control) 2) sesbania application at the rate of 1,000 kg/rai 3) rice straw application at the rate of 1,000 kg/rai and 4) sesbania at the rate of 500 kg/rai and rice straw at the rate of 500 kg/rai. The result were shown that sesbania and rice straw treatment had the highest rice dry weight in all growth stages, the highest nutrient uptake at booting stage,...
