“…According to Othman et al (2014a), irrigated rice consume lots of water (1200-1500 mm per season) which is fast becoming scarce even in humid countries such as Malaysia. The increasing water demand from domestic and industrial sectors, decreasing quality and resources, is envisaged to cause a decline in water availability and threaten the sustainable production of irrigated rice production.…”

In Malaysia, the aerobic rice production system is an alternative approach to growing rice in a water-scarce environment. Like irrigated rice, aerobic rice also can sustain a diversity of avian fauna. The current status of birds in the rice fields of Malaysia especially under aerobic rice condition has not been widely researched. Therefore, this study aims to document the richness, diversity and feeding guilds of bird species in aerobic rice cultivation area. Birds were sampled and recorded using four randomly set up mist net at an upscaling aerobic rice plot in Serdang, Selangor during a period of the one month starting from the milky stage of the plant (75 days after emergence) until two weeks after harvest. 139 birds representing 11 species belonging to 7 families were recorded in the aerobic rice plot. The most abundant bird family observed was Estrildidae (80.58%), followed by Hirundinidae (6.47%), and Meropidae and Motacillidae (both recorded 5.04%). Scaly-breasted munia (50.36%) and white-headed munia (28.06%) are the most abundant birds, while other types of munia such as chestnut munia and white-rumped munia are present in small numbers. Munias were the most observed bird species number (36.36%) and therefore can be considered as the main avian pest of aerobic rice. The diversity indices, The Shannon-Wiener Index was 1.43 while The Reciprocal Simpson Index was 2.93. The richness index (The Margalef Index) was 2.03. The Equitability Index was 0.59. In term of feeding guild, most species belong to insectivore (45.45%) and granivore (36.36%) while the rest were piscivore/insectivore and granivore/insectivore. However, the granivore recorded the highest number of individuals (112 or 80.58%) compared to other guilds. Presence of a relatively high diversity of bird species with varieties of feeding guilds indicated that aerobic rice does provide an attractive habitat or foraging site for avian fauna.

“…Dry rice seed following aerobic rice seeding rate 150 kg ha -1 was buried in soil evenly at depth of 1 cm for each pot through direct seeding method. Prior to sowing, the soil was prepared with organic fertilizer at 1500 kg ha -1 (Othman et al, 2014). The pots were placed in a 80-by 60-by 5-cm tray and water was applied from the bottom of pots for vigorous growth of rice seedlings.…”

Weed has become one of the most serious problems in aerobic rice systems. Weed management in aerobic rice system needs a manipulation of optimum N fertilizer application to control the weed and simultaneously enhance aerobic rice growth performance. In this study, three types of N sources (urea, ammonium sulphate and ammonium nitrate) with concentration starting from (0, 60, 120, 180 and 240 kg ha -1 ) were evaluated for effective control of the bioassay species, Eleusine indica, while observing the rice injury level. The data on weed (emergence and shoot fresh weight), while rice growth (root length, shoot fresh weight, shoot height and leaf greenness) was collected in this study. It was found that urea at a higher application rate of 240 kg ha -1 strongly inhibit the emergence and shoot growth of E. indica by >78%. Conversely, ammonium sulphate and ammonium nitrate gave moderate inhibition (58-65% inhibition) on weed emergence and shoot growth at higher application rates of 240 kg ha -1 , respectively. Significant stimulation effect on rice root growth, shoot height, shoot fresh weight and leaf greenness was noticed at a low application rate of 60 kg ha -1 urea, while ammonium sulphate and ammonium nitrate only exerts its stimulation effect starting at 120 kg ha -1 . Stimulation effect on the rice growth was likely negligible at 0 and 4 DAS across urea, ammonium sulphate and ammonium nitrate application rates. However, the rice plants growth increases with increasing growth stage. The finding suggest that application of urea at 240 kg ha -1 starting from 8 DAS of rice growth stage was the most efficient application rate in inhibiting E. indica with the stimulation effect on the growth of rice seedlings.
