Abstract

Tingginya tingkat konsumsi cabai merah besar harus di imbangi dengan produksi agar dapat memenuhi kebutuhan konsumsi cabai merah di Indonesia. Tingkat konsumsi cabai merah besar didalam outlook komoditas tanaman pangan dan hortikultura pada tahun 2017 masih belum terpenuhi sebesar 183.833 ton. Kendala yang di hadapi yaitu tingkat kesuburan tanah yang rendah. Kondisi bahan organik dan silika hasil analisis tanah yang digunakan budidaya tanaman cabai menunjukkan tingkat C-Organik tanah dengan nilai 1,78 % dan silika tersedia 430,6 (SiO2 mg/kg) kedua hara termasuk kedalam harkat rendah berdasarkan panduan analisis tanah 2009. Perlakuan yang dapat dilakukan dengan memberikan pupuk organik dan pupuk silika pada media tanam cabai merah besar. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan menggunakan 3 ulangan dengan faktor pertama pupuk organik (P) terdiri dari 4 taraf dengan dosis pupuk organik 0g, 62,5g, 125g dan 250g. Faktor kedua pemeberian pupuk silika (S) terdiri dari 4 taraf 0g, 0,85g, 1,69g dan 2,59g. Hasil aplikasi pupuk organik dan pupuk silika terdapat pengaruh nyata terhadap pertumbuhan dan produksi tanaman cabai merah. Hasil dapat dilihat pada variabel pengamatan laju pertumbuhan, biomasa, presentase bunga, jumlah buah, dan berat total buah. Perlakuan Terbaik terdapat pada kombinasi Organik 250g dengan Silika 0,85g.

Abstract

Phosphorus (P) is one of the essential nutrients that functions is metabolism in plant. Based on these functions, it indicates that nutrient P has an important role for plant growth and production. However, its availability in soil is very low, which is less than 0.01% of the total P. Therefore, the availability of P nutrients in the soil needs to be increased by increasing the activity of soil microorganisms through the use of phosphate solubilization bacteria. This research is aimed to show the changes in the physiological characteristics of tomato plants through the application of phosphate solubilization bacteria and rock phosphate. Experiment using factorial randomized block design (RBD) which consisted of 2 factors with 2 consultation levels on the first factor (phosphate solubilization bacteria) and 4 levels on the second factor (rock phosphate), and it consist of 8 combinationed of phosphate solubilization bacteria and rock phosphate with 3 replicated. The results showed that the combination treatment of phosphate solubilization bacteria and rock phosphate affected the physiological characteristics of tomato plants, especially on the variables of stomata density, leaf chlorophyll, plant height, plant dry weight, fruit weight and plant P-tissue content in the vegetative final phase. The recommendation of an efficient fertilizer combination to improve physiological characteristics and high yields is use the phosphate solubilization bacteria and rock phosphate 0.69 grams Keywords: phosphate solubilization bacteria, physiological characteristic, rock phosphate

Abstract

Synechococcus sp. is a species photosynthetic bacterium that has symbiotic mutualism with plant.  Research on this field is not many. Foliar application of this bacterium may increase the growth and yield characteristics.  The aim of this research was to determine the effect of Synechococcus sp. application and NPK fertilizer on soybean growth and yield.  The research was conducted in Pusat Inkubator Agribisnis (PIA) Jember University on February until May 2004.  Split plot design was used with 2 factors, Synechococcus sp. as sub plot (B0: without bacteria and B1: with bacteria application) and NPK fertilizers as main plot (P0: 0 g/plant; P1: 0.347 g/plant; and P2: 0.875 g/plant) with three replications. The result showed that the interaction between Synechococcus sp. and NPK fertilizers treatments was not significant.  The  bacteria applications significantly increasing plants growth (42.9%), leaf area index (294.6%), number of productive stem per plant (141.3%), number of productive nodes per plant (40.3%), pods weight per plant (175.2%), number of pods per plant (152.8%), grain weight per plant (80.5%), dry weight (209.8%), and 100 grains weight per plant (3.4%).  The fertilizers significantly affected only on plants growth (44.6%) and number of pods per plant (29.4 %).    Key words:  Glycine, Synechococcus sp., NPK
