There is a question whether it is best to use synthetic or organic materials to fertilize horticultural crops. Fertilizer rate can effect nutritional value of banana squash (Curcubita maxima Duch.) which is used in processed food. Seed were planted in 1990, 1991 and 1992 into beds treated with recommended (base) and twice the recommended (2X) rates of synthetic or organic fertilizers. Lime was or was not first applied in spring 1991. Synthetic fertilizer produced better yields than organic fertilizer. In 1990, the base fertilizer rate improved yield. In 1992, the 2X fertilizer rate improved yield. Liming did not affect yield. Beginning soil pH was 5.55. For lime augmented treatments soil pH was increased to, and maintained at, 5.65 through fall 1992. For no-lime treatments soil pH was approximately 5.3 through fall 1992. Organic materials, likely bound to soil under acidic conditions, are less available and could explain lower yields. The data suggests that soil pH will have to be improved before banana squash yields can be increased using organic fertilizers.

AbstractThe aim of the research was to examine the effect of different fertilizers on the floristic composition and biomass yield of the semi-natural grassland used as hayfield near Vlăhița locality (Harghita County, Romania) in order to improve its management. In the same time the qualitative structure of the studied grassland was evaluated after the first application of the fertilizers. The vegetation survey was made before mowing, and a total of 84 plant taxa were identified. The studied plant community belongs to the association Festuco-Agrostetum capillaris Horv. 1951. From the 31 fodder species, 13 had very good or good nutritional value. The qualitative structure analysis indicates that the vegetation has developed under moderate anthropogenic pressure. Beside the Euro-Asian elements the Circumpolar and the Cosmopolite elements were well represented. Many species with high tolerance for temperature, soil pH, and soil mineral nitrogen content were registered. After the first application of fertilizers in all treated plots the biodiversity increased compared to the control plot. Fertilized plots also had a significantly higher biomass yield than the control plot. All fertilizers reduced the proportion of the species with good nutritional value from the Poaceae family. Organic fertilizer affected positively the proportion of other plant families than Poaceae and Fabaceae. Long-term experiments are necessary to evaluate the response of the vegetation on treatment with organic fertilizer in order to optimize productivity of the hayfield and sustain species richness.

Sustainable agricultural development depends mainly on the recycling of organic wastes to reduce environmental pollution, as well as to reduce the use of mineral fertilizers. Expired milk products are rich in organic carbon and nitrogen, so they are good raw materials for making organic fertilizers. In this study, expired milk products were converted to organic fertilizer (EDPF) by gravity and thermal treatments. The extracted EDPF was used in the nutrition of Williams banana plants under field conditions for two growing seasons. The field experiment consisted of four treatments including: C = control without N fertilization, U = traditional urea, SRU = slow-release urea, and EDPF. EDPF significantly (p < 0.05) improved the growth and yield of Williams banana in comparison to U and SRU. EDPF significantly minimized the soil pH and increased the soil organic-C and cation exchange capacity compared to the other treatments. EDPF increased the total yield of bunches by 20% and 17% in the first and second years, respectively, above U and SRU. EDPF surpassed the traditional and slow-release urea in its ability to supply the banana plants with nitrogen. NH3-N loss from U, SRU, and EDPF reached 172, 132, and 100 kg N ha−1, respectively, which accounted for 34%, 26%, and 20% of the total added nitrogen. Nitrogen loss from the investigated treatments was in the order: U > SRU > EDPF > C. EDPF significantly reduced the ammonia volatilization compared to U and SRU by reducing the soil pH and increasing the soil organic matter. The dynamic of NH3 emissions not only depends on the nitrogen form but also on climatic conditions and concentrations of NH4+ in the soil solution. Protecting the ecosystem and maximizing the benefits of wastes utilization can be done through the recycling of expired dairy products to organic fertilizers.

Rice yield and proper weed control need to be increased through an environmentally friendly agricultural system approach in rainfed land during the dry season by reducing the dosage of synthetic fertilizers. This study aims to determine the effect of different fertilizer applications on rice yield and weed abundance in rainfed land during the dry season. The study used a split-plot design, with the main plot of rice variety, i.e., Situ Bagendit and IR-64, and subplots of fertilizer, namely synthetic fertilizers (N, P, K), organic fertilizers + P60 + ½ dose of synthetic fertilizers, organic fertilizers + PGPR + ½ dose of synthetic fertilizer and organic fertilizer + P60 + PGPR + ½ dose of synthetic fertilizer with three replications. The variables observed were rice yield components, namely panicle length, total empty grain and content per panicle, grain weights per hill, effective plot and hectare, 1000 grain weight, harvest index, and weeds summed dominance ratio (SDR). The synthetic fertilizers and three various organic fertilizers, biological fertilizers, and synthetic fertilizers gave different results on the SDR of weeds. The weeds of Sphenoclea zeynalica and Cyperus difformis showed consistent dominance with higher SDR than other weeds, i.e.,> 15 and > 10, respectively. The application of organic and biological fertilizers with half the recommended dosage of the synthetic fertilizers is equivalent to applying the recommended dosage of synthetic fertilizers on rice yield during the dry season on the rainfed dryland with low rainfall intensity and a low yield of 1.3–1.7 t/ha.

<p><em><strong>Counseling of Soil Fertility, Organic Fertilizers, Pests and Plant Diseases for Baranuri Farmers Group</strong>. </em>The Baranuri Farmers Group (KT. Baranuri) is one of the providers of vegetables for the people of Ende City. The results of interviews with farmers obtained several problems, namely, there is no data on soil fertility and lack of understanding of soil fertility, organic fertilizers, pests and plant diseases. The solution given is to analyze soil pH and organic-C to be used as a reference for soil fertility conditions as well as counseling about soil fertility, organic fertilizers, pests and plant diseases. This service activity aims to provide information on soil fertility, increase farmers' knowledge regarding soil fertility, organic fertilizers and plant pests and diseases. The counseling method used is a group approach. Purposive soil sampling, samples were taken diagonally. The organic-C content was analyzed in the laboratory by Walkley and Black method, while soil pH was measured directly on the field using 4 in 1 Soil Survey Instrument and then matching with the criteria of assessment of soil analysis results by the Indonesian Soil Research Institute. The results obtained were the soil pH was 4-5 (very acidic-acidic) and soil organic C was 2.03-2.37% (moderate). The extension activities were succeeded in increasing public knowledge from 46.7% to 86.7% (an increase of 85.7%). The recommendation from this activity is to create a demonstration field to apply an organic fertilizer that can be observed directly by farmer groups.</p>

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.

High Yields

In the face of skyrocketing prices of inorganic fertilizers, organic materials are considered the alternative sources of fertilizers. Research institutions have over the years succeeded in demonstrating high yield responses to recommended usage of organic fertilizers. Furthermore, organic fertilizer (biofertilizers) is a vital component of sustainable agriculture. The sound management of organic fertilization must attempt to ensure both an enhanced and safeguarded environment. Most Farmers in Vihiga County have adopted use of organic fertilizers. Despite this, crop yields remain low in farmers’ fields due to low soil fertility and inability of farmers to optimally use organic fertilizers. Researchers often use optimal organic materials recording high yields in experimental and farm demonstration fields. Little or no research has been done to determine why farmers still record low yields despite a lot of extension outreaches to promote available organic matter technology packages in the study area. This paper reports findings of a study carried out to determine factors that limit optimal use of organic fertilizer by farmers in Vihiga County, Kenya. The objective of the study was to compare organic fertilizer usage in farmers’ field with optimal (recommended) rates to determine if the usage were significantly different. This was aimed at providing advice based on empirical evidence to farmers on whether there is need to improve usages of organic fertilizer and to determine if low intensity of organic fertilizer was a possible cause of recorded low yields in farmers’ fields. Purposive sampling was used to select farmers who were using organic fertilizer for soil fertility. A total of 120 farmers were selected to provide data needed for the study. Primary data was collected using questionnaires and data was analyzed using descriptive statistic (t-test). The results of the analysis indicated a significant difference in the usage between what farmers applied and what was recommended by research. Usages of organic fertilizer among the sampled farmers were much lower than the recommended levels explaining the low maize yields among farmers in the study area. The study rejected the hypothesis that the farmers’ usages of organic fertilizer was not statistically significant different from that recommended by research institutions. This is because average usage of organic fertilizer of 320.3 kg/ha was significantly below those recommended by researcher of 5ton/ha (at 99% usage. Farmers must follow appropriate promoted technology recommendations. The study recommended promotion of organic fertilizer. Farmers should be sensitized on the need to bridge the gap between the current and the recommended usage for them to realize the benefits of organic fertilizer.

Shallot is one of important horticultural crops in Indonesia; shallot consumption per capita is estimated to be 4.6 kg per year. The objective of this study was to evaluate the effect of combining biofertilizer and organic fertilizer on the production of shallot in Sukabanjar village, Pesawaran, Lampung, Indonesia. The study was set up using a randomized completely block design with two factors, biofertilizers and various organic fertilizers, i.e. cow manure, chicken manure, rice straw compost, oyster mushroom baglog.  Our study demonstrated that combining biofertilizer and organic fertilizer significantly increased the number, diameter, and fresh and dry weight of tubers of “Bima Brebes” shallot. Shallots treated with biofertilizer combined with oyster mushroom baglog produced the highest tuber yield of 1788 g compared to 282 g in the control.
