The objective of this study was to evaluate the responses in grain yield and zinc concentration wetland upland rice varieties Zn fertilizer application different growing conditions. (Chainat 1; CNT1) (Kum Hom CMU; KH CMU) were grown under waterlogged well-drained soil conditions with or without application. Zinc (ZnSO4) applied at 0 60 kg ha−1 three stages tillering, booting, flowering. In vari...

nitrogen use efficiency (nue) is usually lower in paddy rice (oryza sativa l.) than in upland crops. for this reason, any attempt to improve nue through the use of different nitrogen (n) carriers, different rice cultivars, properly timed n application, the use of ni-trification and urease inhibitorsis of prime interest. moreover, zinc (zn) next to n seems to be the most important soil factor af...

Embrapa has led breeding programs for irrigated and upland rice (Oryza sativa L.) since 1977, generating a large amount of pedigree phenotypic data. However, there were no systematic standards data recording nor long-term preservation reuse strategies. With the new aim making practical, we recovered all available structured it into Rice Breeding Dataset (ERBD). In its current version, ERBD incl...

Upland rice production is often constrained by phosphorus deficiency (P) and drought events. Methods are needed to maximize P use efficiency, while promoting deep root development mitigate drought. This study evaluates micro-dose placement as a technique enhance resilience of upland rice, thereby hypothesizing that enhances development, stimulated the local supply in planting hole, compared bro...

Recent field experiments have shown that high chloride (Cl) in irrigation waters can increase soil cadmium (Cd) uptake by crops because of the formation of soluble ion-pair complexes of Cd with Cl in soil solution. The present study was aimed at testing a hypothesis that KCl in granulated PK fertilizers may enhance Cd uptake by crops from Cd-containing P fertilizers because of close contact bet...

Abstract Identification of genetic superiority is needed to anticipate problems such as local rice extinction and environmental stress due global climate change. This study aims determine the upland in South Sumatra, opportunities for its use a donor gene creation new high-yielding varieties. A research on eight was conducted May-September 2021. The method scope are inventory rice, identificati...

A pressure chamber and a root pressure probe technique have been used to measure hydraulic conductivities of rice roots (root Lp(r) per m(2) of root surface area). Young plants of two rice (Oryza sativa L.) varieties (an upland variety, cv. Azucena and a lowland variety, cv. IR64) were grown for 31-40 d in 12 h days with 500 micromol m(-2) s(-1) PAR and day/night temperatures of 27 degrees C an...
