This research aims to find out the effect and functional relationship of coconut ash organic fertilizer application on the increasing yield and quality of waxy corn. There are seven treatments of coconut ash fertilizer dosage, i.e. 0.00 ton/ha, 0.75 ton/ha, 1.50 ton/ha, 2.25 ton/ha, 3.00 ton/ha, 3.75 ton/ha, and 4.50 ton/ha. Data is analyzed using one way anova, t test for 2 independent samples, and simple linear regression analysis. Fertilizer dosage has significant effect on ear height position from soil surface, the number of seed row on ear, ear weight with and without dried husk, waxy corn production with and without dried husk, and starch, amilose, and amilopectin contents. The highest average of ear height position and the amount of seed row is obtained at dosage 0.75 ton/ha. Dosage 2.25 ton/ha gives highest average for ear weight with and without dried husk, while dosage 3.75 ton/ha results highest average for variables of waxy corn production with and without dried husk. Dosage 3.75 ton/ha also gives highest average for starch and amilopectin contents and lowest average for amilose content. One way relationship happens between fertilizer dosage with ear height position, the amount of seed row, ear weight, waxy corn production, starch and amilopectin contents.

In this study, we investigated the effects of the combined application of different doses of potassium and organic fertilizers on the nutrient uptake, yield, and quality of Newhall navel oranges (Citrus sinensis Osb. cv.). The citrus trees were treated with potassium fertilizer alone or with one of three combinations of organic and potassium fertilizers. Spring shoots, autumn shoots, and fruit were collected when they reached maturity, and the relevant indexes were determined by conventional methods. The soil carbon flux was measured 15, 35, 65, and 95 days after fertilizer application by a soil gas flux measuring instrument. The results showed that the dry weights of leaves and twigs of the spring shoots were 43.1% and 99.8% higher in the OM15+K05-treated (15 kg organic manure and 1.05 kg potassium sulfate per plant) than in the OM0+K25-treated (1.25 kg potassium sulfate per plant) plants, respectively. Combined potassium and organic fertilizer application helped the shoots and fruits to absorb more mineral nutrients. As a result, the fruit yield increased, fruit surface color improved, and skin thickness became thinner. The internal quality of the fruit was also improved by the combination of different potassium fertilizers and organic fertilizers. The fruit quality was optimal for the OM10+K15-treated plants. The recommended doses of organic and potassium sulfate fertilizers for Newhall navel orange orchards with purple paddy soil in southwestern China are 5–10 kg/plant and 1.15–1.20 kg/plant, respectively.

Postharvest Quality

Long-term use of inorganic fertilizers on leafy vegetables can increase soil acidity, harmful to the environment and leaving bad effects on human health. Organic fertilizer application is one of the safer alternatives with many beneficial effects by supplying nutrients for plant growth, environmental-friendly and producing an optimum quality of vegetables. Different organic amendment such as vermicompost, biochar and microbial compost has different effect on plant growth performance since good bacteria could improve structure of the soil and nutrient absorption. Therefore, this study aims to evaluate the effects of organic fertilizer on the growth performance and postharvest quality. The experimental design during planting was conducted in randomized completely block design with a factorial arrangement of treatmentswhile for postharvest quality study was conducted in completely randomized design. Organic fertilizer of vermicompost (110 g/plant), biochar (100 g/plant), microbial compost (80 g/plant) and chicken manure (37.5 g/plant) were treated on Pak choy two times on day 10 and day 24 after transplant. This research revealed the plant growth including plant height, leaf number and leaf length of Pak choy in all treatments were increased as growing stage increased. However, at the end of growing stage, microbial compost and vermicompost resulted in the highest of growth characteristics. In terms of postharvest quality, microbial compost showed the highest fresh weight and premium quality. This study proved that microbial compost at 80 g/plant exhibited optimum growth performance and the best postharvest quality of Pak choy.

Effect of organic (biogrcen) and inorganic fetilizers (ammonium sulphate and SP36) on the yield and quality of the temanggung tobacco in andosol soil was studied at Galapansari - Temanggung, from Februai to December 2001. The organic and inorganic fetilizers were formulated in 10 packages, namely : (1) 570 kg ammonium sulphate (AS) ♦ 100 kg SP36; (2) the recommended rate for temanggung tobacco (20 000 kg stable manure 500 kg AS + 100 kg SP36; (3) 5 000 kg organic fetilizer (OF); (4) 7 500 kg OF; (5) 8 500 kg OF; (6) 10 000 kg OF; (7) 12 500 kg OF; (8) 14 500 kg OF; (9) 7 500 kg OF + 3 500 kg sUble manure (SM); (10) 7 500 kg OF + 4 500 kg SM. All the rates of fetilizers were based on one hectare planted area (16 500 plants) The expeiment was designed as a randomized block in four replicates. Results showed that organic fertilizer waa more effective than stable manure in improving die growth, yield and quality of temanggung tobacco. A the rate of 5 000 kg was sufficient to produce high ( 6 313 kg fresh or 800 kg sliced died leaves), grade index (51.68) and crop index (55.31).

Fulvic acid is an extraction product of humus which is very potential for supplement fertilizer and able to reduce either inorganic or organic fertilizer application. The information about fulvic acid application as supplement fertilizer on ginger in Indonesia is still limited. The objective of the study was lo find oul the efect of fulvic acid as supplement fertilizer on the growth, productivity and quality of young ginger. A green house trial was conducted from July lo November 1996. Five levels of fulvic acid concentration, 0, 2.5, 5, 7.5, and 10% were sprayed every week from 4 to 1 5 weeks ater planting (WAP). A randomized block design was used with five replicates. The results indicated that the growth of plant height and number of tiller of ginger increased rapidly al 8 WAP, then il became slowly from 12 lo 1 5 WAP Application 10% of fulvic acid was able to increase vegetative parts 99.6%, fresh and dry weight of rhizome 89 and 125% respectively, and starch content of rhizome 22.6%. To find oul of the optimal effect of fulvic acid on productivity and quality of ginger, a further research using higher level and application frequency of fulvic acid as an extract product from several humus types in Indonesia is needed.

Nutrient application is one of the major inputs required for hydroponic production of cucumbers. Reduced nutrient solution concentration with supplementary foliar fertilizer application may maintain yield and quality of mini-cucumber, while decreasing the production costs. An experiment was conducted to determine the effect of foliar fertilizer in combination with reduced nutrient concentrations on the yield and quality of hydroponically grown mini-cucumber in a plastic tunnel. Mini-cucumber plants were grown in sawdust, fertigated with nutrient solutions containing 100% (control), 75%, 50%, or 25% of the recommended nutrient concentration (NC) and two foliar fertilizer applications (no foliar and foliar application). The highest fresh and dry weight of mini-cucumber plants were obtained with 75% and 100% NC and decreased with 50% to 25% NC application. The number of marketable fruit and marketable yield on mini-cucumbers increased with 75% to 100% NC, followed by 50% NC, as compared with 25% NC. Deformed fruit were significantly lower at 25% NC than at 50%, 75%, and 100% NC. Foliar fertilizer application did not have an effect on mini-cucumber yield, but reduced the yellowing of fruit. Fruit mineral content (P, Fe, and Mn) was significantly improved by 100% NC. Improvement in yield at 75% and 100% NC was as a result of improved plant height, leaf chlorophyll content, plant fresh and dry weight, and the increase in nutrient uptake of N, P, K, and Mn, which was evident in the analysis of cucumber leaves. The reduced NC of 75% can maintain yield and quality of mini-cucumbers, whereas the application of foliar fertilizer had a limited effect.
