Mekanisme Fisiologi Toleransi Cekaman Aluminium Spesies Legum Penutup Tanah terhadap Metabolisme Nitrat (NO3-), Amonium (NH4+), dan Nitrit (N02-)

The experiment was aimed to investigate the Al-tolerant mechanisms physiology of legume cover crops species related to metabolism NO3-, NH4+, and N02-. The results revealed that an addition of Al had less effect on Al-tolerant species compared to Al-sensitive in term of reduction in NO3-, NH4+ and N02- uptake. The reduction in Nitrit of the Al-tolerant species under Al treatment was less than in Al-sensitive species. The results suggested that in tolerant legume cover crops species, the higher level of Al tolerance seems to have emanated from efficient NO3- metabolism and the higher N02- to NH4+

Response of Some Rice Cultivars in New Opening Paddy Fields with High Fe2+ Using Multi-packet Technology

The main obstacle to increase rice yield in new opening paddy fields, is that high levels of dissolved ferrous ions(Fe2+) which toxic to plants. This research aimed to study the growth and yield of several rice cultivars tolerant toFe2+ in the new opening paddy fields with multi-packet technology. The experiment was conducted from April toDecember 2010, at the new opening pay fields in Koto Baru of Dharmasraya District, West Sumatra. Experimentsused a factorial in a Completely Randomized Design with three replications. The first factor was, selected ricevarieties which were: Krueng Aceh; IR 36; Tukad Balian; Ciherang; and Cisokan. The second factor was thedifferent plant spacing which were a 30 × 30 cm with two seeds per hole, and Plant spacing (10 × 10) × 30 × (10 × 10)cm with one seed per hole. The rice cultivation with packet technology can improved the growth and yield of paddyrice cultivated in new opening paddy field high in Fe2+.
