Efecto de labranza, manejo de rastrojo y fertilización de nitrógeno sobre el contenido de humedad y desarrollo del cultivo de trigo. Colegio de Postgraduados
Osorio Hernández, Victorino.
Se estudió la influencia que ejercen los residuos, el efecto de los diferentes tipos de labranza y la fertilización, sobre el contenido de humedad, desarrollo y rendimiento de trigo. Se incluyen resultados de dos ensayos, localizados en la parte noroeste de México, en el Centro Experimental Norman E. Borlaug en un suelo Chromic Haplotorrert (Hyposodic Vertisol (Calcaric, Chromic)), bajo en materia orgánica (<1%), en condiciones semi-áridas. Se comparan prácticas agronómicas que difieren en tipo de labranza (camas permanentes y camas convencionales), manejo de rastrojo (dejar, empacar o quemar), dosis de fertilización de N bajo diferentes regímenes de riego y con rotación maíz-trigo. Se midieron el contenido de humedad en el perfil (0-60 cm) antes y...

Rice straw incorporated just before soil flooding increases acetic acid formation and decreases available nitrogen Rev. Bras. Ciênc. Solo
Knoblauch,Ronaldir; Ernani,Paulo Roberto; Deschamps,Francisco Carlos; Gatiboni,Luciano Colpo; Walker,Timothy Wayne; Lourenço,Késia Silva; Martins,Acácio Agostinho; Pegoraro,Angélica.
Incorporation of rice straw into the soil just before flooding for water-seeded rice can immobilize mineral nitrogen (N) and lead to the production of acetic acid harmful to the rice seedlings, which negatively affects grain yield. This study aimed to evaluate the formation of organic acids and variation in pH and to quantify the mineral N concentration in the soil as a function of different times of incorporation of rice straw or of ashes from burning the straw before flooding. The experiment was carried out in a greenhouse using an Inceptisol (Typic Haplaquept) soil. The treatments were as follows: control (no straw or ash); incorporation of ashes from previous straw burning; rice straw incorporated to drained soil 60 days before flooding; straw...

การจัดการฟางข้าวในพื้นที่ทำนาอย่างต่อเนื่อง Thai Agricultural
Nittaya Ruensuk; Pranom Mongkonbunjong; Chalermchat Leuchikam; Wassana Inthalaeng.
Straw management by incorporation into the soils is an alternative method to avoid straw burning before land preparation.The experiment was conducted at Pathum Thani Rice Research Center and Suphan Buri Rice Research Center during 2006-2007. It was comprised of 3 trials, i.e., effect of amount of straw incorporated into soils to rice growth and yield, effect of straw management methods to rice growth and yield, and effect of straw incorporation period to rice growth and yield. The results showed that straw incorporation rate of 0-800 kg/rai did not affect early growth stage (number of plants/m2 at 15 days after planting) and yield. Number of plants/m2 at 15 days after planting was decreased by straw incorporation at the rate of 1,200-1,600 kg/rai whereas...
