Weedy rice (Oryza sativa) I. Grain characteristics and growth response to competition of weedy rice variants from five Asian countries por Chauhan, Bhagirath S., Johnson, David E.

“…Weedy rice is a serious weed of cultivated rice in most of the rice-growing areas of the tropics and yet, despite its importance as a weed, limited information is available on its biology in Asia. A study was conducted to determine the seed characteristics and growth response to competition of weedy rice variants from five Asian countries (India [IWR], Malaysia [MWR], Philippines [PWR], Thailand [TWR], and Vietnam [VWR]) when grown alone or with either 4 or 12 cultivated rice (‘IR72’) plants. …”

Nitrogen Fertilization of Direct-Seeded Flooded Vs. Transplanted Rice. I. Nitrogen Uptake, Photosynthesis, Growth and Yield por Schnier, H.F., Dingkuhn, M., De Datta, S.K., Mengel, K., Faronilo, J.E.

“…Direct‐seeded flooded rice (Oryza sativa L.) culture is becoming an increasingly popular alternative to transplanting in some regions of Asia. Two field studies were therefore conducted to compare the growth patterns of wet‐row‐seeded and transplanted ‘IR64’ rice as affected by rate of N fertilizer application (0 and 90 kg N ha−1 in 1987 and 0, 30, 60, 90, 120, and 150 kg N ha−1 in 1988). …”
