Saturated soil culture (SSC) technology appropriate to prevent pyrite oxidation on tidal swamps and has been proved to increase the productivity of soybean on non-tidal swamp. The objective of the research was to determine the growth response of soybean varieties under saturated soil culture on tidal swamps. The research was conducted at Banyu Urip, Tanjung Lago, Banyuasin District, and South Sumatera Province, Indonesia from April to August 2009. The experiment was arranged in a split plot design with three replications. The main-plot of the experiment was water depth in the furrow consisted of 10, 20, 30, and 40 cm under soil surface (USS). The subplot of the experiments was soybean varieties consisted of Tanggamus, Slamet, Wilis, and Anjasmoro. No-watering was arranged out of the design as a comparison. The result showed that nutrient absorption of N, K and Mn by Tanggamus was higher than those of other varieties, except K, however K absorption of Tanggamus was not significantly different from Anjasmoro. P and Fe absorption of Tangamus tended to be higher than the other varieties, although statistically they were not affected by variety. However, technically and economically, 20 cm USS was the most appropriate water depth for soybean production at tidal swamps.

Corn is one of the important food crops and feeds in the world. Conversion of agricultural land into non-agricultural land is one of the major causes of the decline in corn production. Saturated soil culture (SSC) is a cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. This technology can prevent pyrite oxidation in the tidal swamp. This research aimed to study the effect of temporary fl ooding under saturated soil culture on the growth and productivity of corn. The research was conducted at Karya Bhakti village, Rantau Rasau, Tanjung Jabung Timur, Jambi Province, Indonesia. The experiment used a split plot design with three replications. The main plot is fl ooding condition, consisted of 1) saturated soil condition continuously, from planting until harvesting time (as control), and 2) saturated soil condition from 0 to 10 DAP (Days after Planting) + fl ooding from 11 to 13 DAP + saturated soil condition from 14 to 28 DAP + fl ooding from 29-31 DAP + saturated soil condition from 32 DAP until harvesting time. The subplot is corn variety, “Sukmaraga”, “Bisma”, “Pioneer 27”, and “Bima 20”. “Pioneer 27” had the highest productivity of 9.33 t.ha-1. Corn varieties with moderate tolerance to temporary fl ooding were “Sukmaraga” and “Bisma”, whereas “Pioneer 27” and “Bima 20” are sensitive to fl ooding.

Phytophthora root and stem rot, caused by Phytophthora megasperma Drechs. f. sp. Glycinea Kuan & Erwin, is an important disease of soybean in several major growing areas across the world. Susceptible genotypes can be completely devastated, but cultivars with a high level of field resistance are available. Although high soil moisture is known to predispose to infection by Phytophthora, in the absence of this disease soybean is relatively tolerant to soil waterlogging, and has been shown to respond positively to continuous watering in the Saturated Soil Culture (SSC) system. The impact of Phytophthora on plants grown in SSC was investigated at two sites in south-east Queensland. At both sites, there were no differences between plants grown in SSC and conventional furrow-irrigated treatments in the rate or ultimate extent of disease development: susceptible cultivars succumbed to the disease, while cultivars with field resistance remained free of symptoms. A fungicidal seed dressing improved emergence and reduced initial disease infection, and improved seed yield in some cultivars. It was concluded that Phytophthora root and stem rot is not a limitation to the use of Saturated Soil Culture in soybean providing resistant cultivars are available.

The main problem encountered by soybean crop in acid sulfate tidal lands is less availability of P, because of its chemical bond with Fe. Heavy dose of  fertilization often lead to high fertilizer residue, wich could be used for crops farming using AMF. Research was conducted to study the effect of soybean culturing technique and AMF inoculants source on growth of  soybean. The treatments consisted two factors, arranged in a randomized block design with three replications. The first factor was four inoculants sources of AMF, namely AMF and without inoculation AMF, inoculants from rhizospheres of kudzu (Pueraria javanica), sorghum (Sorghum bicolor), corn (Zea mays) and soybean (Glycine max). The second factor was culturing tehnique, namely water saturated and dry soil culture. Soybeans were grown in pots containing 5 kg soil derived from tidal land,  Simpang Village, District of Berbak, East Tanjung Jabung Regency,  Jambi Province. Results showed that the interaction saturated soil culture with inoculants from corn’s rhizosphere had positive effect on the variability of N, P and K uptake, N and P content in the plant, relative efficiency of inoculants and relative efficiency of P uptake, stem diameter, biomass dry weight, the number of filled pods and seed dry weight of soybeans. Dry soil culture with inoculants of corn’s rhizosphere had greater root colonization, but overall for the growth and grain yield of soybean, saturated soil culture with inoculants from corn rhizosphere has better effect on other growth variables.

The response of soybeans to saturated soil culture (SSC), achieved through continuous furrow irrigation, was evaluated in two studies in the Ord Irrigation Area in north Western Australia. In the first study, the effect of SSC on 14 genotypes was compared with conventional irrigation after every 60 mm pan evaporation (CI60), in an early wet season sowing. Averaged across genotypes, seed yields with SSC were increased by 0.74 t ha-1 or 21% above the mean yield of 3.47 t ha-1 with the CI60 treatment. Among genotypes, the advantage with SSC ranged from 2 to 49%. In the second study, the effect of SSC on growth and yield of three cultivars of different maturity was evaluated in a late wet season sowing, where crop durations were shorter than in the first study. There was a strong interaction between irrigation method and cultivar. Average seed yields of the latest maturing cultivar Durack were 10% greater with SSC, average yields of the intermediate cultivar Ross were relatively unchanged, while average yields of the earliest cultivar Buchanan were reduced by 24% with SSC. In both studies, and regardless of time of application of the SSC treatment, a transient chlorotic phase developed which tended to be more severe when SSC was applied earlier in crop growth. Where the chlorosis had dissipated by flowering, and providing crop duration was sufficient to compensate for the initial depression in shoot growth, seed yields were promoted by SSC. Taken together, the two studies indicate that substantial yield increases are possible with SSC in this environment, with the extent of the increases depending on genotype, crop duration, and the timing of application of the treatment.

ABSTRACT Reductions in soybean yields are mainly linked to the occurrence of dry spells, which are becoming more frequent due to climate change. Thus, the aim of this study was to evaluate soybean cultivars irrigated with different water depths under center pivot. The experiment was conducted during the 2014/15 growing season, under center-pivot irrigation in Chapadão do Sul, MS, Brazil. The design was a randomized block in split plot with four replicates, where plots consisted of 4 water depths (0, 50, 75 and 100% of crop evapotranspiration - ETc) and the subplots of 6 soybean cultivars (NA 5909 RR, DM 5958 IPRO, Anta 82 RR, M 7110 IPRO, Desafio RR, M 7739 IPRO). The cultivar Desafio RR was the one that best responded to irrigation, increasing yield to 6174 kg ha-1 against 3798 kg ha-1 under rainfed condition. The highest yield under rainfed condition was obtained by the cultivar NA 5909 RR, reaching 4806 kg ha-1. This shows that some cultivars can respond positively to irrigation, resulting in increased yield, depending on the genetic characteristics of each one.
