An exessive use of inorganic fertilizers in agriculture cultivation system causes many disadventages, such as increase cost production, reduce farmer’s income and soil fertility, and harm our environment. Therefore, it is needed to find out raw materials for development of organic biostimulant and biofertilizer inducing essential element absorption, growth and yield of plants, which are adaptive to our environment as well. Previous researchres reported that seaweed contained plant growth hormones and essential elements in liquid and solid extracts respectively. This article reports effect of solid and liquid extracts of Sargassum cristafolium on growth and yield of rice plants. The extracts were extracted according to modified procedure.. Solid extract (350 gr) of Sargassum cristafolium was mixed with soil (6650 gr) to become 7 kg soil media. Moreover, liquid extract (10%) of Sargassum cristafolium was sprayed to rice plants once a week during vegetative growth. The results shown that addition of 350 gr of solid extract to soil media increased growth (plant high, tiller number, shoot dry weight and root dry weight) and yield (penicle number and grain weight per plants) significantly compared with those of plants which were not supplied with solid extract. However, spraying liquid extract of Sargassum cristafolium did not affet significantly growth and yield of rice plants, even small change happen in growth and yield parameters of the rice plants supplied with solid extract. This indicates that solid extract is a potential source for development of biofertilizer which is adaptive to our environment to support sustainable agriculture system.

Abstrak : Pemupukan anorganik pada sistem budidaya pertanian menimbulkan beberapa masalah, antara lain biaya produksi meningkat, pendapatan petani menurun, tanah menjadi keras dan tidak subur, serta mencemari lingkungan. Karena itu, perlu ada upaya untuk menemukan sumber bahan baku pupuk yang mudah didapat, murah dn ramah lingkungan. Beberapa peneliti sebelumnya melaporkan bahwa rumput laut mengandung fitohormon dan elemen essensial yang dapat merangsang pertumbuhan dan hasil tanaman. Artikel ini melaporkan pengaruh ekstrak cair dan padat Sargassum aquifolium terhadap pertumbuhan dan hasil tanaman mentimun. Ekstrak cair dan padat alga tersebut diperoleh dengan metode Godlewska et al., 2016. Ekstrak cair (10%) disemprotkan satu kali seminggu selama pertumbuhan vegetatif. Ekstrak padat (5%) diberikan pada media tanah saat tanam. Ekstrak cair secara signifikan mempengaruhi sebagian besar parameter pertumbuhan (tinggi tanaman, jumlah cabang dan berat kering tunas) dan pertumbuhan generatif (jumlah dan berat buah per tanaman), namun ekstrak cair tersebut tidak secara signifikan mempengaruhi berat kering akar. Fenomena serupa juga ditemukan pada pengaruh ekstrak padat terhadap pertumbuhan dan hasil tanaman mentimun. Hasil penelitian ini memberikan indikasi bahwa ekstrak cair yang dilaporkan mengandung fitohormon, dan ekstrak padat yang mengandung elemen essensial dapat dikembangkan sebagai “biostimulan” dan “biofertlizer” organik yang dapat memacu pertumbuhan dan produksi tanaman.Kata kunci : ekstrak cair, ekstrak padat, Sargassum quifolium, pertumbuhan, hasil, tanaman mentimun.Abstract : Aplication of inorganic fertilizer in agriculture cultivation system causes some disadventages, such as increase cost production, reduce farmer’s income and soil fertility, and hqrm our environment. Therefore, it is needed to find out raw materials for fertilizer which easy to obtain, cheap and adaptive to our environment. Previous researchres reported that seaweed contained plant growth hormones and essential elements stimuliting growth and yield of plants. This article reports effect of liquid and solid extracts of Sargassum aquifolium on growth and yield of cucumber plants. Liquid and solid extracts were obtained according to modified Godlewska method (2016). Liquid extract (10%) was sprayed once a week during vegetative growth. Moreover, solid extract (5%) was applied in plant media. Liquid extract influenced significantly most growth parameters, such as plant height, branch number, shoot dry weight and yield parameters like fruit number and fruit weight per plant, but liquid extract did not significantly affect root dry weight. Similar phenomena was also found on the effect of solid extract on growth and yield of cucumber plants. The results suggest that liquid and solid extracts containg plant growth hormones and essential element respectively, could be developed as organic biostimulant and biofertilizer inducing growth and plant production.Keywords : liquid extract, solid extract, Sargassum quifolium, growth, yield, cucumber plants.

<br />Seed priming has been widely used to improve seedling vigor of several crops  such as corn, wheat, and rice. Seed priming with zinc to increase seedling tolerance on submergence stress had never been evaluated. The objective of this research was to identify agronomical and physiological characteristics of several rice genotypes during seedling stage at submergence stress following zinc priming treatment. This research used factorial randomized block design with three replications. The first factor was rice genotypes and second factor was zinc solution of ZnSO4.7H2O. Seeds were soaked with Zn solution at different concentrations namely 0, 2.5, dan 5.0 mM respectively for 24 hours. After that the seeds were germinated on soil media in side the plastic box. Fourteen days-old seedling were submerged in water for 5 days and then return to normal condition for recovery. Parameters being observed included seedling dry weight, shoot carbohydrate, and leaves chlorophyl which were measured after 10 days of recovery. Seedling height was measured once a week from 2nd to 4th week. Results showed that intolerant genotypes to submergence stress grew faster but seedling dry weight, shoot carbohydrate and leaves chlorophyll content were lower compared to those tolerant genotypes. Local and national varieties which were not tolerant to submergence stress could be improved by priming treatment with 5.0mM zinc.<br /><br />Keywords: abiotic-stress, seeds- priming <br /><br />

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 />

Field experiments were conducted at Punjab Agricultural University, Ludhiana (Punjab) to study the effect of different agronomic aspects of bed planting on growth and yield of rice during Kharif seasons of 2012 and 2013. The 30 days old seedlings of both rice varieties PR-118 (V1) and PR-116 (V2) were transplanted on 15th June (D1), 30th June (D2) and 15th July (D3). The two rice varieties were transplanted under bed planting (M1) and conventional planting (M2) methods respectively. The results showed that growth parameters like number of tillers per plant, dry weight per plant leaf area index (LAI) and plant height were significantly higher in bed planting than conventional method. In bed planting method, grain yield of rice (48.82q/h) was found to be more than the conventional method (35.74 q/h) during 2012.Varieties PR-118 yielded 47.61q/h more than PR-116 (39.97 q/h) in bed planting. Yield contributing characters like number of effective tillers, number of grains per plant and 1000-grain weight of rice were more in bed planting than conventional method. Harvest index and biological yield was also found to be more in bed planting method than conventional planting. Rice transplanted on 15th June yielded (50.15q/h) more than 30th June (41.45q/h) and 15th July (35.27q/h). Similar results were found in Kharif 2013. Interaction between dates of transplanting and varieties and between varieties and planting methods were found significant.

Pot experiments were carried out with rice (Oryza sativa L.) to evaluate the plant response of different amendments to ameliorate heavy metal toxicity. Cowdung and lime were applied at the rate of 10 ton/ha. Both cowdung and lime application led to an increase in growth of rice and significant reductions of Zn, Ni, Cu and Cr in plant. The length, fresh and dry weight and N, P, K, Na, Ca and Mg concentrations in rice plants were increased significantly. The concentrations of Cu, Zn, Ni, Pb and Cr in rice grown on contaminated soils were significantly higher as compared to the control. Cowdung and lime significantly reduced Cu, Zn, Ni, Pb and Cr concentrations in comparison to control. Chromium concentrations in lime treated plants were reduced by 57.89% in rice as compared to cowdung. Lime proved to be more efficient in reducing the concentration of metals in rice plants. J.

Marginal land along the coast should be utilized to increase the national rice production. In addition, the use of saline resistant varieties, it is necessary to determine the best seedling age for saline soil. This study aimed to evaluate the growth and yield responses of two rice varieties transplanted at different seedling age on saline soil. The experiment was arranged in a factorial Randomized Completely Block Design (RCBD) with three replications, conducted at saline coastal area of Baros, Yogyakarta, starting from January to June 2017. The first factor was rice varieties, consisting of Dendang and IR-64. Meanwhile, the second factor was the seedling age, consisting of 2 and 4 weeks after sowing (WAS) seedlings. The results showed that the growth and yield of two rice varieties (Dendang and IR-64) showed significant difference, and Dendang showed a better performance than IR-64. The higher yield of Dendang compared to IR-64 was supported by higher plant growth (shoot dry weight) and yield components (number of seeds per panicle, seed weight per plot, and productivity). The 2 and 4 WAS seedlings did not give significantly different effects on nearly all growth variables. However, 2 WAS Dendang rice seedlings had higher shoot dry weight. Meanwhile, IR-64 had higher leaf greenness in 4 WAS seedlings compared to that in 2 WAS seedlings.

Beneficial Elements

Background: The beneficial elements availability such as silicon was determined rice growth and yield. Rice requires a different dose of silicon during the growing period. Experiment was aimed to investigate the effect of silicate levels, rice varieties and the interaction of the two on the growth and yields of two local Indonesian varieties of rice. Methods: A completely randomized design of factorial pattern with 4 replications was used in the experiment. Treatments consisted of No added SiO2 (Si-0); added 100 and 200 kg SiO2 ha-1, respectively for Si-100 and Si-200 and two local rice varieties, Pandan wangi (P1) and Mentik susu (P2). Result: The treatment had no significant effect on growth and yield of rice. Addition of 100 and 200 kg SiO2 ha-1 to P1 and P2 did not show a significant difference on the growth and yield of rice compared to control (P0). Plant height and root dry weight at P1 was lower than P2, but the 1,000-grain weight was showed, vice versa. Silicon addition up to 200 kg SiO2 ha-1 may not be recommended to be applied in rice cultivation, especially Pandan wangi and Mentik susu varieties. Improving the two varieties, further research is needed by increasing the silicon doses.

Background: Rice has become a primary daily necessity for mostly Indonesian population. The upsurge of national rice production can be done by agricultural intensification through the application of NPK fertilizer. Objective: This study aimed to determine the optimum dose of NPK Mutiara fertilizer, which could provide the highest rice yield of Ciherang variety in Alluvial soil. Methods: This study was a single factor arranged in a completely randomized design (CRD) with three replications. The NPK Mutiara fertilizer treatment consisted of four doses, i.e., 0, 160, 320, and 480 kg ha‾1. The data observations were analyzed by using analysis of variance (ANOVA) at 5% significance levels. The difference between the averages of the treatment was compared using Duncan′s new multiple range test (DMRT) at 5% significance levels. Results: The results of the research showed that the application of NPK Mutiara fertilizer could increase the growth and yield of the Ciherang variety in Alluvial soil. The quadratic regression analysis revealed that the optimum dose of NPK Mutiata was obtained at 656 kg ha‾1 with the maximum grains dry weight of 4.26 tons ha‾1. The application of NPK Mutiara fertilizer could not affect the shoot root ratio and panicle length. Conclusion: The findings of the study suggest that the application of NPK fertilizer interval has not reached the optimum dose in Alluvial soils for the Ciherang variety. Therefore, application of NPK Mutiara fertilizer with doses higher than 480 kg ha‾1 is required for alluvial soils.
