The decline in rice yields as a result of excessive chemical fertilizer (CF) inputs is a matter of great concern in rice-growing regions of Asia. In two-year’s field experiments, the nitrogen, phosphorus, and potassium (NPK) status, growth characteristics and yield of rice were examined by application of poultry manure (PM), cow manure (CM) and compost (CP). Organic fertilizers were applied as EMN (estimated mineralizable N) based on their total N content. Six treatments were assigned in a randomized complete block design: (1) no-N fertilizer (N0); (2) 50% CF (CF50), (3) 100% CF (CF100); 50% CF + 50% EMN from (4) PM or (5) CM or (6) CP. Compared with CF100, the CF50PM50 (total N ≥ 4%) accumulated higher N, P and K content in leaf, sheath, panicle and seeds, resulting in greater growth and yield. The CF50PM50 increased yield by 8.69% and 9.70%, dry matter by 4.76% and 5.27% over CF100 in both years. The continuous application of CF50CM50 (total N < 4%) and CF50CP50 (total N < 4%) treatments led to similar NPK contents but higher yields than those of CF100 treatment in 2018. In conclusion, the organic fertilizer (total N ≥ 4%) with the EMN method enhances higher N availability in each year. Continuous application of organic fertilizer (total N < 4%) over two years effectively increased N availability in the second year. The 50% organic fertilizer (total N ≥ 4%) and 50% CF led to increased NPK availability and rice yields over the 100% CF treatment, reducing CF usage and leading for sustainable agriculture.

The research was conducted to monitor the influent of abattoir wastewater compost on rice growth and yield in Benin-Owah River Basin in Illah, Delta State, Nigeria. The compost was applied at 0, 2.5, 5.0, 10 t/ha, and NPK15:15:15 at 250 kg/ha laid in randomized complete block design with four replicates. Rice seeds were sown for two years, and residual effects were evaluated in the third year. Rice plant height, stem circumference, and the number of tillers was measured at two weeks intervals while rice yields have taken at harvest. Soil samples were taken yearly to monitor nutrient changes. Data obtained were analyzed with analysis of variance and mean separated with Duncan Multiple Range Test at α0.05. In the first year, NPK15:15:15 significantly gave the highest dry matter (6.28±1.45 t/ha) and grain yield (2.4±0.53 t/ha). While in the second year, 10 t/ha treatment produced the dry matter (7.69±1.60 t/ha) and grain yield (2.6±0.53 t/ha). In a residual study, the highest grain yield (2.8±0.72 t/ha) was produced in the plot treated with 10 t/ha, and it also gave the highest pH, organic carbon, total nitrogen, and available P content. The compost at the rate of 10 t/ha can increase soil fertility and rice yield.

The Application of High Puddle and Organic Fertilizer on Rice Yield Ciherang Variety. Rice (Oryza sativa L.) is the staple vital food of Indonesian people. National rice production has not been able to meet the needs of the population, despite many efforts such as the use of improved varieties, fertilization, the use of agricultural machinery, and the use of pesticides. This study aimed to determine the effect of water level and organic fertilizers on crop yields of rice. This experiment used randomized block design in a simple treatment, namely the combination of the water level and the dose of organic fertilizer. This research using analysis of variance (ANOVA) to determine the effect of treatment on the variables tested. If treatment significant it will be followed by LSD test 5%. The results showed that the treatment of combination of water level and organic fertilizers provide a very real effect on the growth and yield of rice (Harvest dry grain yield ha-1). Harvest dry grain yield ha-1 obtained at the highest AMP2 treatment, namely without flooding water and organic fertilizers and 6 t ha-1 at 10.92 t ha -1 were significantly higher 70.09 % compared to the treatment of farmers. Based on the research results, it can be recommended that the application of water-saving cultivation of organic fertilizer with a dose of 6 t ha -1 needs to be done to improve rice yields.

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.

The Effect of Organic and Inorganic Fertilizers on The Growth and Results of Green Mustard (Brassica rapa L.). Green mustard (Brassica rapa L.) is a vegetable that preferred by many consumers, this causes many farmers cultivate this vegetables. One of the important factor in the cultivation of green mustard is fertilizer type. Alternative to improve soil quality and fertility is by providing organic matter. A field research was conducted to evaluate the effect of organic and inorganic fertilizers on the growth and yield of green mustard, in Banjar Taman Tande, Baturiti Village, Bedugul from April to June 2018. This study was designed with a Randomized Block Design with nested patterns consisting of two factors. The first factor was the type of fertilizer, which was consisted of four types of organic fertilizer, namely: vermicompost, cow manure, chicken manure, goat manure and inorganic fertilizers (NPK Mutiara). The second factor was fertilizer dosage, which was consisted of three levels, namely: 0 tons/ha, 15 tons/ha, and 30 tons/ha, while for NPK Mutiara fertilizer dosages, namely: 0 kg/ha, 150 kg/ha, and 300 kg/ha.The results showed that the effect of organic and inorganic fertilizers were not significantly different on the growth and yield of green mustard plants and RAE values. The total N content of soil on vermicompost treatment was 0.23% equal to NPK Mutiara. The total population of soil microbes on vermicompost treatment under dosage of 15 tons/ha and 30 tons/ha were 1.4 x 106 cfu/g that was much higher compared to NPK Mutiara 150 kg/ha fertilizer (0.3 x 106 cfu/g).

Compost is an important source of organic fertilizer that can be used to amend degraded soil to improve soil nutrient and crops yield. This experiment was to evaluate the effect of sawdust – piggery compost on soil properties, growth and yield of maize and it was carried out at the Ambrose Alli University Teaching and Research Farm, Emaudo, Ekpoma, Edo State. The experiment was fitted in a Randomized Complete Block Design (RCBD) with seven treatments and three replicates. The treatments were; control (0), 2, 4, 6, 8, 10 and 12 tonnes of sawdust – piggery compost per hectares (ha-1). Data collected were analysed using ANOVA and LSD was used to separate means. Soil nutrients were below critical levels and the application of compost improved fertility status of the soil. Growth parameters, dry matter yield, cob weight, grain yield and nutrient uptake were determined. It was observed that application of Sawdust – piggery compost significantly (p 0.05) increased the growth of maize compared to control. The application of 8 to 12 tonnes of sawdust – piggery compost significantly (p 0.05) increased the plant height, leaf area and stem girth of maize compared to other treatments. The application of 8 to 12 tonnes per hectares (ha-1) of sawdust – piggery compost significantly (p 0.05) increased the cob weight, grain and dry matter yield of maize compared to other treatments, however, the application of 10 t ha-1 of compost to maize increased grain yield of maize than others rate of applications with the yield value of 4.60 t ha-1. The uptake of nitrogen, phosphorus and potassium were higher with application of 12 tonnes of compost. In conclusion, the application rates of 10 t ha-1 of sawdust – piggery compost per hectare on nutrient depleted soils will improve the growth and yield of maize.

Field experiments were conducted at the Agricultural Engineering Experimental Farm of The Federal University of Technology, Akure, during 2006/2007 and 2007/2008 seasons to investigate the response of cassava under drip irrigation. The experiment was laid out in a randomised complete block design (RCBD) with three replications. The treatments were based on four different water regimes; with T100 receiving 100% available water (AW), T<sub>50</sub> and T<sub>25</sub> receiving 50% and 25% of AW and T<sub>0</sub> with zero irrigation (control treatment). Disease free stems of the cassava cultivar TMS 91934 were planted at a spacing of 1 m by 1 m. The results indicated that T<sub>100</sub> full treatment produced the highest average total dry matter yield of 49.12 and 37.62 t/ha in 2006/07 and 2007/08 cropping seasons, respectively. However, the average total dry matter production in T<sub>50</sub>, T<sub>25</sub>, and T<sub>0</sub> showed significant differences in their values. Low total dry matter yields of 7.12 and 5.92 t/ha, respectively, were associated with T<sub>0</sub> for the two cropping seasons. The total water use of 1491.75 and 1701.13 mm was recorded for T<sub>100</sub>, while total water use of 729.00 and 651.13 mm were obtained for T<sub>0</sub> in the two cropping seasons. The water use efficiency determined for the two cropping seasons ranged between 7.38 kg/ha and 32.93 kg/ha. The percentages of total water applied from total water use for T<sub>100</sub> were 51.11% and 61.72%, while 14.83% and 17.85% were recorded for T<sub>25 </sub>for 2006/07 and 2007/08 cropping seasons, respectively.

One effort that can be done to improve soil fertility and crop yields is fertilization. Fertilization using a mixed source fertilizer (MSF) is an option to overcome the impact of inorganic fertilizer use and organic fertilizer drawbacks. This study aims to evaluate the effects of MSF application on the chemical properties of Inceptisol and rice yields. A field experiment was conducted using a completely randomized block design (RCBD) with two factors and three replications. The first factor was the three formulas of MSF (F1, F2, F3) and the second factor was MSF doses (0, 2.5, 5, 7.5, 10 Mg ha-1). The results show that there is no significant difference on the total soil N, available soil P, plant height and total number of tillers of rice plants applied with the three MSF formulas. The increased MSF doses applied significantly improve the soil chemical properties of Inceptisol and rice yields. The application of 10 Mg ha-1 MSF increases total- N (57.89%), available-P (29.13%), exchangeable-Ca and -Mg (117% and 250%, respectively), plant height (40%) and total number of tillers (43.2%) in comparison to those without MSF application. There are interaction effects between formulas and doses of MSF on the amount of exchangeable-K, organic-C content, and CEC of the soil and rice yields. The application of 10 Mg ha-1 MSF F3 results in better effects on the amount of exchangeable-K, organic-C content and CEC of the soil, and number of productive tillers and rice yields than the application of other MSF formulas. The MSF can be used as an alternatif fertilizer that can improve Inceptisol productivity.

<p>ABSTRACT</p><p>Degradation of soil fertility due to inaccurate  application of fertilizer become one of the factors causing the stagnant rice productivity improvement in Indonesia. Straw incorporation, organic fertilizers and biofertilizers applications potentially reduces a rates of inorganic fertilizers and improves soil fertility. The aim of this study was to evaluate growth and yield of 3 lowland rice varieties (high yielding variety, new plant type, and local variety) in response to reduce NPK rates with straw incorporation, organic fertilizer, and biofertilizer in 7th planting season. The research was conducted at rice field in Karawang, West Java, from April-August 2013. The research was arranged in split plot randomized block design with 3 replications. The main plot was fertilizer application consisted of 10 treatments (combination of organic and inorganic fertilizers), while the sub plot was rice varieties (Ciherang, IPB 3S, and Mentik Wangi). The application of inorganic fertilizer, 400 kg NPK 30-6-8 ha-1, was control treatment. Plot size was 6.5 m x 10 m, with a double row spacing (25 cm x 15 cm x 50 cm). The result showed that growth of the three varieties was not significantly different so as the yield at 50% reduced NPK rate with incorporation of straw, organic fertilizer and biofertilizer. Adding of solid and liquid organic fertilizer, and biofertilizers on treatment of straw incorporation + 50% NPK rate was unnecessary due to insignificant yield increase.</p><p>Keywords: Ciherang, fertilizer, IPB 3S, local variety, Mentik Wangi, new plant type</p>
