Limitations of productive land causing agricultural extension leads on marginal land. Peatlands are one type of land including the criteria for marginal land. Destruction of peatland ecosystems arising from land management and the selection of one commodity which is not in accordance with the characteristics of peatland. Damage criteria peat in government regulations to function cultivation is more than 0,4 m below the peat surface. One alternative for the agricultural development of peatlands associated with groundwater levels ≤0,4 m to do with the development of food crops, especially rice crops. This is because the root system of the rice crop is only about 40-50 cm categorized shallow roots, thus suitable for development on peatland shallow. This study aims to determine the response growth and yield of rice plants with organic and inorganic fertilizer application by microbial cellulolytic on peat soil. The experimental was conducted from November 2017 to January 2018 in Laboratory of Soil Science and Plant Laboratory, Faculty of Agriculture at Universitas of Riau.

A field experiment was conducted once at Isabela State University, Jones, Isabela, Philippines during the wet season of 2018 to determine the impact of seaweed extract added with varying levels of inorganic fertilizer on the growth and yield of upland rice (Oryza sativa L.) cultivars. In the study, five fertilizer levels and a farmer’s practice as a control combined with seaweed extract was used. The study used Randomized Blocks in a Factorial Scheme with six treatments replicated thrice as follows: Factor A: V1-Pinilisa, V2-Palawan and Factor B: F1-150-100 kg NP ha-1 (Farmer’s Practice), F2-40-10 kg NP ha-1 (100% Recommended Rate), F3-20-5 kg NP ha-1 (50% Recommended Rate), F4-40-10 kg NP ha-1 + 3 L/ha. Seaweed extract, F5-20-5 kg NP ha-1 + 3 L/ha. Seaweed extract and F6-3L/ha. Seaweed Extract. The findings revealed that seaweed extract combined with inorganic fertilizer application influenced the growth and yield of rice. Pinilisa cultivar obtained a higher yield compared to the Palawan cultivar. The combination of seaweed extract and inorganic fertilizer shows highly significant differences especially concerning the number of productive tillers, filled grains, 1000 grain weight and straw weight. The return on investment showed that Pinilisa cultivar fertilized with 3 L seaweed extract is more economical in upland rice obtaining the highest with 95.47%. Seaweed extract as foliar fertilizer can be applied not only in rice but also in other crops. Application of seaweed extract on rice can reduce the amount of fertilizers.

ABSTRACT<br />Application of organic fertilizer into the soil is designated as a source of macro, micro nutrients and organic acids; it also acts as soil ameliorant that improve physical, chemical and biological properties of soil. Application of high rates organic fertilizer has a constraint namely the availability and ease of application. Therefore, it is necessary to learn the use of organic fertilizer with low rates to improve the efficiency of chemical fertilizers. This research was aimed to study the effect of organic and inorganic fertilizers on growth and yield of paddy rice, as well as the efficiency of N, P, K inorganic fertilizer. Field experiment was conducted at Sawah Baru Research Station, University Farm IPB, Bogor, West Java from September to December 2013. The experiment used Randomized Block Design consisted of two factors: rates of organic fertilizer (0, 250, 500, 750, and 1,000 kg ha-1), and rates of inorganic fertilizer (0, 100, 200, 300, and 400 kg ha-1). The results suggested that the application of 1,000 kg organic fertilizer ha-1 + 400 kg inorganic fertilizer ha-1 did not show significant interaction. Application of organic fertilizer alone up to 1,000 kg ha-1 resulted in low growth and yield. Increasing rates of  application up to 400 kg inorganic fertilizer ha-1 increased the growth and yield of paddy rice. The highest N efficiency was 89.19% at a rate of 500 kg organic fertilizer ha-1 + 200 kg inorganic fertilizer ha-1, whereas the highest efficiency of P and K, respectively were 69.55% and 92.52% at a rate of 750 kg organic fertilizer ha-1 + 300 kg inorganic fertilizer ha-1.<br />Keywords: NPK, organic fertilizer, paddy rice

ABSTRACT<br />    <br />As one of the silica (Si) accumulator, rice (Oryza sativa L.) requires large amounts of silica for growth. This study aimed to determine the effect of liquid silica fertilizer application on lowland rice growth and yield, and its roles in drought stress responses. The experiments were conducted at Sawah Baru rice field and Cikabayan Greenhouse Experiment Station, IPB, Bogor during the period of January to May 2016. The field experiment was set up in a randomized complete block design with 7 treatments and three replications. The greenhouses experiment was arranged in a split-plot randomized block design with 3 replications. The main plots were 5 levels of liquid silica fertilizer application, while the subplot was 5 level of various soil water contents. The results of the field experiment showed that the application of liquid silica fertilizer increased rice shoot dry weight, total and productive tiller numbers, and yield per plant, but did not increase yield per hectare. Meanwhile at greenhouse experiment, it showed that the use of liquid silica fertilizer reduced the number of rice stomata, but did not increase cuticle thickness and grain yield per plant. Silica application was not effective to alter drought in rice.<br /><br />Keywords: IPB 3S, silica fertilizer, soil water content, water use efficiency   <br /><br />

The purpose of this study was to determine the effect of chicken manure and urea on the growth and yield of onion leaves on inland peat soil. The design used was a Completely Randomized Design (CRD) factorial with two treatment factors. The first factor is that chicken manure fertilizer application consists of 4 levels, namely: 0, 5, 10 and 15 tons/ha, and the second factor is the provision of urea that consists of 3 levels, namely: 0, 125 and 250 kg/ha. The variables measured were plant height and fresh weight of the leaves of onion plants. The results showed that the interaction between chicken manure and urea fertilizer had no significant effect on all variables observed at all ages observed. Single factor giving 15 tons/ha of chicken manure fertilizer showed growth and better results on the average variable plant height and fresh weight of the leaves of onion plants in inland peat soil. Single factor giving of urea 250 kg/ha showed growth and better results on the average variable plant height and fresh weight of onion plants in inland peat soil.

Organic And Inorganic Fertilizers

[CABBAGE (Brassica olacea var. capitata) GROWTH AND YIELD AFFECTED BY COMBINATION OF ORGANIC AND INORGANIC FERTILIZER APPLICATIONS]. The use of organic fertilizer increasingly sought by farmers due to the increase in demand for organic products by consumers and also awareness of the sustainability of the land. The use of organic fertilizers in the cultivation alone could improve the soil quality but needs to be balanced with inorganic fertilizers to meet the nutrient adequacy. This study aims to examine the effect of organic and inorganic fertilizers combination on the growth and cabbage yield, and also to determine the most efficient dosage combination of organic and inorganic fertilizers. This research was conducted at the IPB Pasir Sarongge Experimental Station, Cianjur, West Java from November 2020 to February 2021. The study was compiled using RCBD with 4 replications and 7 treatments. The results showed the combination of 0.75 doses of inorganic fertilizer (150 kg/ha of urea, 75 kg/ha SP36, and 75 kg/ha KCl) and 3 tons/ha of organic fertilizer could increase 14.87 to 15.44% plant height and the number of leaves at 12.82 -15.11% compared to the same dose of inorganic fertilizer treatment alone. The combination of 1 dose (200 kg/ha of urea, 100 kg/ha SP36, and 100 kg/ha KCl) inorganic fertilizer application and 2 tonnes/ha of organic fertilizer could increase 50,60% yield/plot and yield/ha cabbage than 1 dose of inorganic fertilizer treatment..

Abstract The study was conducted to evaluate the growth and yield response of M20 with the application of Nostoc and to determine the ideal combination of inorganic fertilizer and Nostoc. Based on the result of the study, in terms of growth parameters; application of 3 g Nostoc with 1/2 RRIF gave the best response among the treatment in plant height, while application of 3 g Nostoc with 3/4 RRIF was the best treatment when it comes to days to flowering. Furthermore, the application of full RRIF was the best in terms of chlorophyll content. In yield parameters, the application of 3 g Nostoc with 1/4 RRIF gave significance response to grain yield and biomass. While the application of no Nostoc with 1/4 RRIF had the heaviest 1000 grain weight. For the number of tillers per plant (14.7), the application of 3 g Nostoc with 3/4 RRIF gave the best response among the treatments. And for the number of filled grains, rice grown without Nostoc but fertilized only with 1/2 RRIF had the most number of filled grain. Overall, Nostoc treatment did not significantly alter the response of M20 based on all agronomic parameters tested in the study.

A pot experiment was designed for two consecutive years of (2018 and 2019) to investigate the effect of optimal use of potassium fertilizer by applying at different rates 0, 10, 20, 30, 40, and 50 mg K kg-1 10 kg pot-1 soil. Rice cv. HUR-36 (Malaviya Dhan-36)] crop was transplanted by maintaining four seedlings in each pot and potassium fertilization effect on plant growth and yield attributes of rice was recorded. The experiment was carried out in completely randomized design (CRD) with seven treatments viz., T1: absolute control (0:0:0), T2: 60:30:0 mg kg-1, T3: 60:30:10 mg kg-1, T4: 60:30:20 mg kg-1, T5: 60:30:30 mg kg-1, T6: 60:30:40 mg kg-1 and T6: 60:30:50 mg kg-1 corresponding to 120, 60, 60 (N:P2O5: K2O) kg ha-1. The experiment was conducted in triplicate. The data pertaining to experiment revealed that plant height, effective no. of tillers, chlorophyll content and grain and straw yield were significantly increased as the scheduled rates of potassium fertilizer application increases. In treatment T5 receiving 60:30:30 mg kg-1, potassium was general recommendation but due to intensive cropping of rice, mining of K was noticed. Therefore, increased dose of potassium should be recommended to maintain the replenishment of K in soil system and other side benefit cost ratio should not affect negatively. The treatment received extra doses of T6 to T7 (60:30:50 mg kg-1) showed highest growth in plant and yield of rice but in steady state which is not beneficial economically. Hence, in T7 benefit cost ratio will be poor. In the present experiment, T6 maintains all fulfillment of K whether in plant or soil system.

The use of Enriched organic fertilizer to Reduce organic and Inorganic Fertilizer Application and Increase the Potato Yields in the Highlands of Indonesia. Experiment was conducted at Experimental Station of Indonesian Vegetable Research Institute (the elevation of this site is 1250 meters above sea level) from June to November 2017. The objective of the experiment is to obtain an efficient technology of nutrient management in terms of organics and biological fertilizers and to obtain appropriate technology of potato tuber. The implementation of the reseach was preceded by making compost manure using Bio-decomposer for one month and enriched by using Bio-Phosphate and benficial Micro-organism, dolomite, ash husk and rock phosphate, then continued with its application in the field with potato as an indicator plant. The treatments were arrange in a randomized complete block design (RCBD) with four replications. The treatments included the use of organic fertilizer in terms of horse manure enrichment at a rate of 20 and 40 t/ha and inorganic fertilizer at a rate of 0, 500 and 1000 kg NPK and horse manure 40 t/ha + 1000kg NPK/ha as control plants (farmer's practice). Results of the experiments indicated that the use of horse manure enriched by microorganism can reduce a rate of hord=se manure from 40 ton/ha to 20 t/ha to produce growth and yield of potato. Enriched horse manure can also reduce the use of inorganic fertilizers by half rate ( 500 kg NPK / ha). Combination of enriched horse manure 20 t / ha + 500 kg NPK / ha is more efficient to increase yield of potato tubers. The use of enriched horse manure does not seem to affect the improvement of soil fertility, especially for the availability of soil P and soil biological activity.  Keywords: Solanum tuberosum, horse manure, decomposer microbes, inorganic fertilizers, tuber yields.
