Assessment for increasing productivity of suboptimal land with using three kinds of organic fertilizer and six rice varieties had been conducted in the Debowae village, Waeapo district, Buru regency at 2011.  Purpose of the assessment were to determine the effect of three types organic fertilizer and the use of six Inpara varieties to growth and productivity of rice in sub-optimal land. Study used a split plot design with three replications (farmers as replicates), where the main plot was three types of organic fertilizers (livestock manure, granular organic, and petroganic), while the subplot was 6 varieties Inpara (Inpara 1, Inpara 2, Inpara 3, Inpara 4, Inpara 5, and Indragiri). The soil types at the study site based on soil classification were Endoaquepts with soil fertility status was low. The study results  showed  that  the use of organic  manure combined with inorganic fertilizers,  both  from  livestock manure, while granular organic and petrogranic, gave an average crop growth and yield better than the results obtained by farmers outside of the study. Average petroganic fertilizer had a better growth and higher crop yields compared to other organic fertilizers. The six varieties of rice swamps that were examined (Inpara 1, Inpara 2, Inpara 3, Inpara 4, Inpara 5, and Indragiri) had the average growth and better yields than rice varieties used by farmers outside of the study (2.75 t ha-1). Varieties Inpara 4, Indragiri, Inpara 1 and  Inpara 2 had average yield above 7 t ha-1, while Inpara 3 and  Inpara 5 average above 4 t ha-1. Combination of granular organic fertilizer with Inpara 4 variety and petroganic with Indragiri variety had the best results (8.37 and 8.02 t ha-1), while the lowest yield (4.48 t ha-1) was reached at combination of  livestock manure with Inpara 5 variety.Keywords: adaptive varieties, land and plant management, organic fertilizers, suboptimal land [How to Cite: Marthen PS and MLJ Titahena. 2014.

<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>

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.

The productivity of organic farming has mainly focused on its relative crop yields than the proportions of organic matters in soil. However, organically cultivation changes crop yields at the same time it depends on types of crops grown. Here, we provide a pot experiment on the rooftop in Latin Square Designs (LSD) with a Diamant variety of potato and four treatment combinations to evaluate variety’s growth and yields. T0: Control, T1: 100% organic fertilizer, T2: 75% organic fertilizer+25% soil and T3: 50% organic fertilizer+50% soil was used for the present study with three replications. Our analysis showed the tallest (23.78 cm) plant was in T2 followed by T1 and T3 (23.37 cm and 23.14 cm, respectively). T2 produced the maximal (76.44) number of leaves per stem followed by T2 and T3 (73.44 and 74.11, respectively). T1 generating the maximal number (6.89) of tubers per hill was significant than all the other treatments. The highest weight (19.13 gm) per tuber per hill was examined in T2 followed by T1 and T3 (17.05 gm and 12.91 gm, respectively). T2 produced the utmost tuber length (3.78 cm) followed by T1 and T3 (3.39 cm and 3.23 cm, respectively. 75% organic fertilizer+25% soil has concluded the potential to be grown successfully and the most suited treatment for production of potato (Diamant) in coastal areas of Bangladesh.

Agriculture has been considered as one of the priority countries sectors in our research; the share of agriculture in the gross domestic product of the world leading countries was investigated. The theoretical and practical aspects of non-waste agricultural production development using animal waste and crop residues fermented in biogas plants are revealed. The authors substantiate the relevance and potential of the introduction of waste-free technology which has considerable advantages of energy autonomy both for the enterprise and the country. The state of humus content in soils of Ukraine is also considered. International experience has been evaluated, which consists in the ability of agricultural waste both to produce alternative sources of energy and to use the products of their processing as organic fertilizers that significantly increase crop yields. The first steps of the Ukrainian agricultural enterprises to introduction of non-waste production on the example of the company LLC Organic-D have been presented; it heats and electrifies the complex, dries crops, and also uses organic fertilizer (digestate) due to waste processing in the biogas station. As a result of the research, it was found that the application of organic fertilizer can have a positive effect on soil recovery, because the soil acidity has changed from a level of weak acid (5.4 pH) to a level close to neutral (6 pH) for one year of its application. To conclude, the obtained results prove the relevance of the research problem.

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 study investigated the effects of animal manures (cow manure, CoM; chicken droppings, CkD; and pig manure, PiM) applied at 15 t ha-1 equivalent rate on the soil and growth performance of okra grown in a degraded ultisol. The treatments (CoM; CoM; PiM and Control unamended) were laid out in a completely randomized design and replicated three times. Animal manure application had significant effects on soil properties. Soilorganic matter increased by over 9% in the amended treatment relative to the control treatment. Except for N, increases in P (circa 14-70%)and K (circa 15-46%) nutrients were higher for CkD treatment than in other  treatments. Generally, the amended treatments maintained a significantly higher (p ≤0.05) plant leave number, stem girth, plant height, okra pod length and yields when compared with the Control treatment. The results indicated that application of animal manure enhanced okra growth performance. The findings suggest that animal manure application can potentially increase okra yield when grown in a degraded soil. It is recommended that farmers use ample (15 t ha-1) ) quantity of animal manures to increase their crop yields, which invariably will enhance their income. Keywords: Soil fertility, organic fertilizers okra growth, okra yield response, farmers okra yeild.
