“…These results are in line with previous research. Cahyono & Hartati (2013) reported the effect of FDP fertilizer use on lowland rice plants. The application of 75 kg/ha FDP fertilizer (a half-recommended dose) produced rice grains as high as 7.360 kg/ha when applied in 3 times split application.…”

The appropriate method of P fertilizer application is very important for the efficiency of P uptake and yield improvement. This research aimed to assess the growth response, seed product, and P uptake efficiency of soybean to the application of fast dissolved phosphorus fertilizer. Two consecutive potted experiments under greenhouse condition were conducted using Alfisols from Jumantono Karanganyar as planting media. The soybeans were planted and treated with six doses of P fertilizer. The treatments were designed in a completely randomized experiment with 5 replications. In the first experiment, the plants were harvested at the maximum vegetative growth for measurement of plant growth components and P uptake. In the second experiment, the plants were harvested at optimum grain maturity for seed yield and P efficiency measurements. The results showed that the application of fast dissolved-P fertilizer improved plant growth, seed yield and P uptake efficiency. Fast dissolved-P fertilizer was optimum at a dose of 100 kg/ha which was applied in a split application method at 0, 15, and 30 days after planting. However further field research is necessary to confirm the results.

“…Knowledge of how rice responds to the P fertilizer application time during the growing season is essential for the development of efficient P fertilizer recommendations (Slaton et al, 2002). Cahyono and Hartati (2013) reported that improving the efficiency of P fertilizer can be reached by providing a quickly dissolving phosphate fertilizer. However, as phosphate forms a reaction with other compounds soon after release from the fertilizer, a proper method of P application, split application, should be applied.…”

A field experiment was conducted in 2014 and 2015 consecutive seasons at the farm of Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt to study the performance of the variety rice Egyptian hybrid-1 (EHR1) under different phosphorus fertilizer levels, i.e. control (P1), 18 (P2), 36 (P3) and 54 (P4) Kg P 2 O 5 ha -1 and 2% orthophosphoric acid as foliar spray. The treatments were applied at different periods, namely control (without foliar spray) (F1), foliar spray with 2% of orthophosphoric acid at mid tillering (MT) period (F2), at late booting (LB) period (F3) and at MT + LB periods (F4). The experimental design was split plot where the main plots were arranged in randomized complete blocks with four replications. The phosphorus levels were allocated in the main plots, while sub-plots were received foliar applications with 2% orthophosphoric acid (H 3 PO 4 ). The studied characters plant height, number of tillers hill -1 , panicle length, panicle weight, number of panicles hill -1 , number of filled grains panicle -1 , number of unfilled grains panicle -1 , 1000-grain weight, grain yield t ha -1 , straw yield t ha -1 and phosphorus uptake kg ha -1 . All studied characters increased with all treatment as compared with the control. Application of either 36 or 54 kg P 2 O 5 ha -1 gave the same highest values of the studied characters except empty grains panicle -1 which reached the maximum under the control. A significant increase in each of plant height (cm), number of tillers hill -1 , number of panicles hill -1 , panicle weight, panicle length, number of filled grains panicle -1 , grain and straw yields and P uptake was observed in both seasons. Spray of the tested cultivar with 2% orthophosphoric acid at MT or at MT plus LB gave the greatest values for all studied characters, except the F3 treatment (spray one time at late booting) which gave the least as compared to the other sprayed treatments because the plant had the required amount at this time. The results revealed that the combination of 36 or 54 kg P 2 O 5 ha -1 along with foliar 2% H 3 PO 4 at MT (mid tillering) treatment produced the same greatest values of grain yield and most of growth and yield attributes without any significant difference between them. From economical point of view, the combination of 36 kg P 2 O 5 ha -1 with 2% H 3 PO 4 sprayed at MT was the best combination because it produced the highest grain yield and saved one third of phosphorus fertilizer.

“…Kartika et al (2018) reported that planting pattern and split N fertilizer application increased leaf chlorophyll and nitrogen content during vegetative stage and yield in rice cultivated at riparian wetlands. Increase in rice yield was also reported by Cahyono & Hartati (2013) if P fertlitizer was splitted into two or three times of application. Marlina, Gofar, Subakti, & Rahim (2014) found that composition of 75% of recommended inorganic fertilizer rate with additional biofertilizer increased productive tillers, number of grains per panicle, and weight of milled dry rice.…”

Productivity and cropping intensity on non-tidal wetland in South Sumatra are considerably low and has been underutilized up to now. The majority of farmers in this ecosystem are smallholders with limited adoption capacity on introduced technologies and modern agricultural practices. The objectives of this research were (1) to comprehensively capture multidimensional constrains that restrained local farmers in increasing their agricultural productivity; and (2) to identify, assess, and develop substantially-relevant, financially-affordable, and sociallyacceptable agricultural technologies and practices for smallholder farmers to increase productivity. This research was organized in three main activities: qualitative research employing Grounded Theory procedure, quantitative questionnaire-guided survey, and a series of laboratory and field experiments. The research results indicated that the main constraints in increasing productivity and cropping intensity on the non-tidal wetland in South Sumatra include (1) unpredictable flooding occurrence and low soil nutrients content (agronomic constraint), (2) low financial and technology adoption capacity of local farmers (economic constraint), and (3) public policy has not significantly escalated farmer's motivation to increase food production (social and institutional constraint). This research suggests that multidimensional (technical, financial, ecological, and socio-cultural) approaches should be integrated in collective efforts for sustainably intensifying food production on the non-tidal wetland.
