Organic Compost

Fertility improvement of Ultisol is inevitable to increase growth and yield of chili pepper since the nutrient availability and organic matter of this soil is relatively low. Application of organic fertilizer will enhance microorganism activity in soil, thereafter will improve the availability of nutrients as well as other chemical, physical, biological properties of the soil. Most of manure releases nutrient quite slowly; therefore, addition of nitrogen to soil is expected to speed up the availability of nutrient to plant. Weed based organic fertilizers from Wedelia (Wedelia trilobata) and Siam weed (Chromolaena odorata) biomass have potential to substitute inorganic fertilizer. The objective of the experiment was to compare the effects of weed based organic compost and dry leaves compost with or without addition of nitrogen fertilizer on growth and yield of chili pepper. The experiment was carried out using Completely Randomized Design (CRD) with treatments of 200 kg urea ha-1; Wedelia compost (WDC) 20 ton ha-1; WDC 15, 10, and 5 ton ha-1 with addition of 200 kg urea ha-1 respectively; Siam weed compost (SWC) 20 ton ha-1, SWC 15, 10, and 5 ton ha-1 with addition of 200 kg urea ha-1 respectively; and dry leaves compost (DLC) 20 ton ha-1, DLC 15, 10, and 5 ton ha-1 with addition of 200 kg urea ha-1 respectively. The result revealed that composts with or without addition of nitrogen fertilizer had similar responses on the growth of chili pepper. Wedelia and Siam weeds compost at 20 ton ha-1 tended to give better yield of chili pepper as compared to application of urea alone. This result indicated that weed based organic fertilizers could substitute nitrogen fertilizer.

The Impact

Basic soil productivity (BSP) is the ability of a soil, in its normal environment to support plant growth. However, the assessment of BSP remains controversial. The aim of this study is to quantify and analyze the trends of BSP in winter wheat seasons using the decision support system for agrotechnologie transfer (DSSAT) model under a long-term fertilization experiment in the dark loessal soil region of the Loess Plateau of China. In addition, we evaluated the contribution percentage of BSP to yield and its influencing factors. A long-term fertilization experiment with a winter wheat/spring maize rotation was established in 1979 in a field of the Gaoping Agronomy Farm, Pingliang, Gansu, China, including six treatments: (1) no fertilizer as a control (CK), (2) chemical nitrogen fertilizer input annually (N), (3) chemical nitrogen and phosphorus fertilizer input annually (NP), (4) straw return and chemical nitrogen fertilizer input annually plus phosphorus fertilizer added every second year (SNP), (5) manure input annually (M), and (6) M plus N and P fertilizers added annually (MNP). The application of the DSSAT-CERES-Wheat model showed a satisfactory performance with good Wilmott d-index (0.78~0.95) and normalized root mean square error (NRMSE) (7.03%~18.72%) values for the tested genetic parameters of winter wheat. After the 26-years experiment, the yield by BSP of winter wheat under the M and MNP treatment significantly increased, at the rate of 2.7% and 3.82% a year, respectively, whereas that of CK and N treatments significantly decreased, at the rate of 0.23% and 3.03%. Moreover, the average contribution percentage of BSP to yield was 47.0%, 39.4%, 56.3%, 50.0%, and 61.9% in N, NP, SNP, M, and MNP treatments, respectively. In addition, soil organic carbon contents were the main controls of BSP under the different fertilization conditions in the dark loessial soil area. As a result, the combined application of organic fertilizer or straw and chemical fertilizer can be an effective form of fertilization management to greatly enrich basic soil productivity, continually promote the contribution percentage of BSP, and ultimately increase crop yield.

A field experiment was conducted during 2017/2018 to assess the effects of Argel (Solenostemmaargel, Del. Hayne) and Nitrogen fertilizer on the performance of two Sunflower Hybrid cultivars, with the objectives to exploit an easy, economic, and accessible organic fertilizer, the Argel in the phase of the continuous increasing prices of chemical fertilizers.. This experiment was laid out on spilt-split-plot experiment in Randomized Complete Block Design (RCBD) with four replications. Observations were taken on some agronomic traits (Plant height (m), Leaf area (LA), leaf Number (NL), Leaf Area Index (LAI) and Mean Seed Weight). The results revealed that the application of Argel and Nitrogen fertilizer have significantly increased the leaf Area (F= 7.22, P < 0.001), Plant Height (F=2.68, P < 0.2001), Leaf Number (F= 3.90, P < 0.0024), Leaf Area Index (F= 3.83, P < 0.0026) and Mean Seed Weight of both Serena and Opera cultivars respectively compared to the control. However, the different treatments of Argel and Nitrogen reflected variable degree of increase for the studied parameters. The study concludes that Argel is very promising, therefore a further study with different levels of Argel including other plant parameters is recommended.

Set Up

In order to study the effects of different fertilization measures on spring tea soil in Southwest Sichuan, five treatments were set up, including no fertilization (CK), full chemical nitrogen fertilizer (CN), 50% nitrogen fertilizer +30% organic fertilizer +20% green fertilizer + microbial fertilizer (NOGM), 50% nitrogen fertilizer +30% organic fertilizer +20% green fertilizer (NOG), 50% nitrogen fertilizer +50% organic fertilizer + microbial fertilizer (NOM). Through the determination of the distribution, organic carbon and total nitrogen content of water stable aggregates, calculated the aggregate stability and carbon and nitrogen contribution rate. The results showed that :(1) compared with CK, fertilization could improve the organic carbon and total nitrogen of soil and the organic carbon and total nitrogen of the aggregates of all sizes. Different fertilization measures had different effects on the distribution of aggregates, but compared with CK, fertilization effectively promoted the stability of aggregates. Fertilization can obviously increased the content of organic carbon and total nitrogen in large aggregates. The contribution rate of organic carbon and total nitrogen in aggregates was mainly from macroaggregates, while that from micro-aggregates was very low. NOGM and NOM were better than other fertilization measures.

Cowpea is prospective as a substitute for soybeans, as raw material for tempeh. In this study, low inputs of cowpea production is proposed. This study aimed to determine the effect of manure and nitrogen fertilizer on the growth and production of cowpea. The study was conducted at the Cikabayan Experimental Station, IPB, Bogor, Indonesia, from November 2018 to March 2019, using a split-plot design. As the main plot was goat manure rates consisted of 0, 2.5, and 5 tons ha-1. The subplots consisted of four rates of nitrogen, namely 0, 15, 30, and 45 kg N ha-1. The results showed that the application of manure increased the fresh weight of the leaf, the number of flower bunches, and the number of flowers. The application of N fertilizer increased leaf fresh weight, leaf area index, dry root weight, and shoot/root ratio at five weeks after planting. The combination of organic fertilizer with a dose of 2.5 tons ha-1 combined with 45 kg ha-1 nitrogen fertilizer tends to give better productivity than without fertilizer. Thus, cowpea can be produced using low input of manure and N. Keywords: leaf area index, leaf weight, flower bunches

Synthetic Nitrogen Fertilizer

Organic fertilizer is capable to decrease the use of synthetic fertilizer due to release of plant nutrients and improvement of other soil properties. The objective of this experiment was to compare the growth and yield of green mustard as affected by cattle manure and litter compost. The experiment was conducted employing Completely Randomized Design with 8 treatments. Treatments included litter compost and cattle manure at rate of 25 Mg ha-1 and 15, 20, 25 Mg ha-1 with addition of 1.85 g nitrogen fertilizer per plant, respectively. Each treatment was replicated 5 times. Soil used in this experiment was Ultisol collected at depth of 0-20 cm. Five kg of soil was mixed with organic fertilizer according to each treatment and placed in 10 kg polybag. Green mustard was planted to each polybag. Nitrogen fertilizer was applied a week after planting. The experiment revealed that application of litter compost and cattle manure at rate 25 Mg ha-1 with additional nitrogen fertilizer resulted in higher green mustard fresh weight per plant and number of leaves. On the other hand, application of both organic fertilizers at rate of 25 Mg ha-1 without addition nitrogen fertilizer as other treatments did not provide significant differences on most variables observed. This indicated that application of organic fertilizer is able to reduce synthetic nitrogen fertilizer for green mustard production.

Biomass transfer using fertiliser tree species is a more sustainable means for maintaining nutrient balances in maize based production systems. This research investigated the combined effects of incorporation of leafy biomass of fertilizer trees as organic fertilizer and urea as inorganic fertiliser for sustainable food production viz-a-viz maize-based crop in semi-arid, Nigeria. The experiment was laid out as 3 x 4 x 2 factorial in a split-split plot design with three replicates. Data were analysed using Analysis of Variance (ANOVA) at p =.05. Albizia lebbeck amended plots consistently had significantly higher values in 2014, 2015 and combined means (12.8 kg ha-1, 13 kg ha-1, 12.9 kg ha1) of cob length, (345.8 kg ha-1, 311.8 kg ha-1, 328.8 kg ha-1) of grains per cob and grain yield (2097.3 kg ha-1, 1667.7 kg ha-1, 1881.9 kg ha-1) throughout the cropping seasons and combinedeffect respectively compared to Parkia biglobosa. Positive significant correlation was experienced between the growth and yield components. Inclusion of nitrogen fertilizer and fertilizer trees improved the production of these maize varieties compared to control. It is therefore concluded that incorporation of Albizia lebbeck with up to 40 kg N ha-1 rate of nitrogen fertilizer into the soilimproved its quality for better yield of both 2009 EVAT and DMR-ESR-7 maize varieties.
