“…A third possibility is that residues increase the availability of soil nutrients. Seng et al (2004) found that when there was a temporary loss of water in flooded rice systems, straw incorporation increased P availability and uptake, increased soil pH, reduced Al toxicity, and increased rice growth. Temporary losses of floodwater are common in rain-fed rice soils (Fukai et al 1998) and were observed in two of the four years at Champassak (Fig.…”

Low yields and high risk characterize many rain-fed lowland rice environments, including those in Laos. Drought and fluctuating soil-water conditions (from aerobic to anaerobic states) can limit productivity and the efficient use of applied nutrients. Although addition of organic matter may improve the efficiency of fertilizer use, on-farm residues, for example farmyard manure (FYM), rice straw and rice hulls, are, currently, poorly utilized in these systems. Single and multi-year experiments were designed to evaluate the effect of these residues on rice productivity and efficiency of fertilizer use at four sites. Rice yield without fertilizer but with addition of residues ranged from 1.1 to 1.7 t ha -1 across sites and years. In response to fertilizer, yields increased on average by 1.4 t ha -1 . For all sites and years there was a significant response of yield to organic residues applied without fertilizer, with responses ranging from 0.2 to 1.4 t ha -1 . In 58% of cases there was no residue·fertilizer interaction (benefits of residues when applied with fertilizer were additive). In 38 and 4% of cases the interaction was negative (no response to residues if fertilizer was already applied) or positive (synergistic), respectively. In the multi-year studies, the type of interaction varied between years, suggesting that seasonal events, rather than soil type, determine the type of interaction. The greatest benefits of applying organic and chemical fertilizers together were observed in years when soil-water conditions were unfavorable (fluctuating anaerobic-aerobic conditions). The longterm effects of these different management strategies on soil nutrient balances suggest that N, P, and K balances were maintained as a result of balanced commercial fertilizer management but that addition of residues further enhanced these balances. All residues, when applied alone, resulted in positive soil Si balances; only with FYM were long-term N, P, and K balances maintained or positive, however. For resource-poor farmers, applying on-farm residues can be a sustainable approach to increasing productivity.

“…Use of organic residues has been shown to enhance nutrient cycling, improve nutrient use efficiency, and increase productivity in rain-fed lowland rice systems in other Southeast Asian countries (Ragland and Boonpuckdee 1988;Willet 1995;Seng et al 2004). Available onfarm residues include rice straw, rice hulls, and farmyard manure (FYM).…”

“…These conditions reduce the content of soil organic matter, and increase the immobilization of nutrients such as phosphorus (Seng et al 2004;Zhou et al 2014). Phosphorus is one of the nutrients limiting plant productivity, because of its essential role in the process of flowering and seed formation.…”

Abstract. Suryantini. 2016. Effect of phosphorus, organic and biological fertilizer on yield of mungbean . The research investigated the effect of phosphorus rates, organic and biological fertilizer on productivity of mungbean grown after rice (cropping pattern: rice-rice-mungbean) and after soybean (cropping pattern: ricesoybean-mungbean). Treatment was arranged in a split plot design with three replications. The main plots were (i) without organic and biological fertilizer, (ii) organic soil treatment (OST) and (iii) phoshpate solubilizing biofertilizer (PSB). The subplots were phosphorus (P) fertilizer rates: 0, 100, 150 and 200 kg SP36/ha. The results revealed that the grain yield of mungbean grown after soybean was not affected by the application of OST or PSB, but it was increased by fertilizer P at 200 kg SP36/ha with an increase of 68%, from 0.60 t/ha (control) to 1.01 t/ha. Conversely, the grain yield of mungbean grown after rice was significantly affected by the interaction between fertilizer P and OST or PSB. The highest yield were obtained from the combination treatments of 150 kg SP36/ha + PSB and 150 kg SP36/ha + OST with an increase of 78% and 71% over control respectively. Increased grain yield was supported by the increase in number of pods, 100 seeds weight and plant P uptake.

“…plant height) and dry matter production under non-flooded condition were suppressed compared with shallow water condition, even though there were no remarkable declines in soil water content and no clear drought symptoms such as leaf rolling in non-flooded condition. P and Fe became less available, and Al more available in aerobic non-flooded condition compared with reduced condition under flooding (Takenaga 1995;Seng et al 2001b), which would have negative effects on rice growth on P deficient Cambodian paddy soils (White et al 1997;Seng et al 2002Seng et al , 2004. Recovery growth after transplanting shock may have been slower under nonflooded condition than shallow flooded condition, resulting in less vigorous vegetative growth (Ikeda et al 2007).…”

In order to assess direct seeding of rice technology to cope with future agricultural labor shortage in Cambodia, agronomic experiments were conducted in 2005 and 2006 to compare direct seeding with transplanting under three water conditions (non-flooded, shallow flooded, and deep flooded conditions) with/without weed control by herbicides (bentazone and cyhalofop-butyl) for two Cambodian rice varieties (shorter stature and early maturity Sen Pidao, taller stature and longer maturity Phka Rumduol). Average rice yield in 2 years was lower in direct seeding (341 g m -2 ) than transplanting (404 g m -2 ), but interaction components with year, varieties, water conditions, and weed management were significant, and the attained maximum yield of direct seeding (510 and 464 g m -2 for Phka Rumduol variety in shallow flooded condition with weeding in 2005 and 2006, respectively) was similar to that of transplanting. Plant length and dry weight of rice were reduced in non-flooded and deep flooded conditions compared with shallow flooded condition, and grain yield was the highest in shallow flooded condition. Yield advantage of Phka Rumduol over Sen Pidao increased under direct seeding, particularly under non-flooded conditions in 2005 because weed infestation was more suppressed in Phka Rumduol even without weeding. Increase in 100 g m -2 of weed infestation prior to heading (dry weight basis) reduced about 20% of attainable yield with weed control. This study identified importance of stature and growth duration of rice varieties and presence of standing water as well as the weed control, in order to develop and extend direct seeding in the Cambodia.
