Ringkasan mizan maulana. pertumbuhan dan hasil beberapa varietas cabai (capsicum annum l.) akibat aplikasi mikoriza pada tanah salin dibawah bimbingan rita hayati sebagai pembimbing ketua dan bakhtiar sebagai pembimbing anggota pemberian mikoriza sangat diperlukan pada pertanian yang menggunakan tanah salin agar tingkat kadar garam yang terdapat dalam tanah tersebut dapat ditoleran oleh tanaman cabai, serta dapat membantu akar tanaman dalam memaksimalkan penyerapan hara khususnya fosfat yang tersedia pada tanah. penelitian ini bertujuan mengetahui pengaruh varietas cabai dan aplikasi jenis mikoriza serta interaksi diantara kedua faktor tersebut terhadap pertumbuhan dan hasil tanaman cabai pada tanah salin. tanah salin yang digunakan dalam penelitian ini dibuat dengan konsentrasi larutan garam 5 kg per 15 liter air dan diberikan sebanyak 200 ml. tanah tersebut telah dianalisis dengan nilai dhl (daya hantar listrik) sebesar 5.5 ms/cm dan termasuk kategori sedang dan jenis tanahnya yaitu entisol. penelitian dilaksanakan di kebun percobaan, laboratorium penyakit tanaman serta laboratorium biologi tanah fakultas pertanian universitas syiah kuala, darussalam banda aceh. rancangan yang digunakan pada percobaan ini adalah rancangan acak kelompok pola faktorial (rak) 4 × 3 dengan 3 ulangan, sehingga memiliki 12 kombinasi perlakuan yang terdiri dari atas dua faktor perlakuan, faktor pertama adalah varietas cabai (v) terdiri atas 3 taraf yaitu: v1 = perintis,v2 = pm 999 dan v3 = lado, faktor kedua adalah jenis mikoriza (v) yang terdiri dari 4 taraf : m0 = kontrol, m1 = mikoriza glomus sp., m2 = mikoriza acauluspora sp. dan m3 = campuran . peubah yang diamati meliputi tinggi tanaman umur 15, 30 dana 45 hst; diameter batang 15, 30 dan 45 hst; jumlah daun 15, 30 dan 45 hst, analisis p tersedia, serapan p tanaman, infeksi akar 45 hst, berat basah dan kering berangkasan, berat buah pertanaman, jumlah buah pertanaman, berat basah dan kering akar, panjang akar dan kadar air buah. hasil penelitian menunjukkan bahwa p tersedia, daya hantar listrik serta analisis serapan p tanaman berpengaruh tidak nyata. analisis tersebut dilakukan untuk mengetahui tingkat kemampuan jenis mikoriza membantu tanaman dalam penyerapan hara p untuk memaksimalkan produksi tanaman cabai, pengaruh varietas cabai berpengaruh sangat nyata pada diameter batang 15 hst, berat berangkasan basah, jumlah buah pertanaman, berat kering buah pertanaman, berpengaruh nyata pada tinggi tanaman 15 hst, diameter batang 30 hst dan berat buah pertanaman, namun berpengaruh tidak nyata terhadap tinggi tanaman umur 30 dan 45 hst, diameter batang umur 45 hst, jumlah daun umur 15, 30 dan 45 hst, berat kering berangkasan, berat basah akar, berat kering akar, panjang akar, jumlah cabang produktif 45 hst dan kadar air buah. hasil analisis ragam menunjukkan bahwa jenis mikoriza berpengaruh sangat nyata terhadap infeksi akar 45 hst dan jumlah buah pertanaman, berpengaruh nyata diameter batang umur 30 hst, dan berpengaruh tidak nyata pada tinggi tanaman cabai pada umur 15, 30 dan 45 hst, diameter batang pada umur 15 hst , 45 hst, jumlah daun pertanaman pada umur 15,30 dan 45 hst, jumlah cabang produktif 45 hst, berat buah pertanaman, berat basah berangkasan, berat kering berangkasan, berat basah akar pertanaman, berat kering akar pertanaman, panjang akar pertanaman dan jumlah kadar air buah. tidak terdapat interaksi antara jenis mikoriza dan varietas terhadap seluruh variabel yang diteliti. kata kunci : salin, cekaman garam, cabai, mikoriza, varietas summary mizan maulana. growth and yield of several paper chili (capsicum annum l.) varieties as the effect by aplication of mycorrhiza in saline soil. supervised by rita hayati as supervisor and bakhtiar as co-supervisor the aplication of mycorrhiza is very necessary in agriculture that uses saline so that the level of salts contained in the soil can be tolerated by chili plants, and can help plant roots maximize the absorption of nutrients, especially available phosphate on the soil. this study aims to determine the effect of chili varieties and the application of the type of mycorrhizae and the interaction between these two factors on the growth and yield of chili plants on saline soil. soil saline used in this study was made with a concentration of 5 kg salt solution per 15 liters of water and given as much as 200 ml. the land has been analyzed with the value of dhl (electrical conductivity) of 5.5 ms / cm and is included in the medium category and the type of soil is entisol. the research was conducted at the experimental garden, plant disease laboratory and soil biology laboratory, faculty of agriculture, syiah kuala university, darussalam, banda aceh. the design used in this experiment was a 4 × 3 random factorial group design with 3 replications, so that it had 12 treatment combinations consisting of two treatment factors, the first factor was chili (v) variety consisting of 3 levels, namely: v1 = perintis, v2 = pm 999 and v3 = lado, the second factor is the type of mycorrhiza (v) which consists of 4 levels: m0 = control, m1 = mycorrhizal glomus sp., m2 = mycorrhizal acauluspora sp. and m3 = mixed. the variables observed included plant age 15, 30 funds 45 dap; stem diameter 15, 30 and 45 dap; number of leaves 15, 30 and 45 dap, available p analysis, uptake of p plants, root infection 45 dap, dry wet and dry weight, weight of planting fruit, number of fruit crops, wet and dry weight of roots, root length and water content of fruit. the results of the study show that p is available, electrical conductivity and analysis of the effect of p uptake have no significant effect. the analysis was carried out to determine the ability level of mycorrhizae to help plants in nutrient uptake to maximize the production of chili plants, the effect of chili varieties had a very significant effect on stem diameter of 15 dap, wet weight, number of fruit crops, dry weight of planted fruit, significantly affected plants 15 dap, stem diameter 30 dap and fruit weight, but no significant effect on plant height aged 30 and 45 dap, stem diameter aged 45 dap, number of leaves aged 15, 30 and 45 dap, dry weight, root wet weight, root dry weight, root length, number of productive branches 45 dap and fruit moisture content. the results of the variance analysis showed that the type of mycorrhizae had a very significant effect on root infection 45 dap and number of fruit crops, significantly affected stem diameter at 30 dap, and had no significant effect on chili plants at ages 15, 30 and 45 dap, stem diameter at age 15 dap, 45 dap, number of plant leaves at the age of 15.30 and 45 dap, number of productive branches 45 dap, weight of fruit crops, weighted wet weight, dry weight, root weight of planted roots, dry weight of planted roots, root length of plantations and number fruit water content. there is no interaction between the type of miikoriza and varieties on all variables studied. keywords : saline, salt stres, chili, mycorrhiza, varieties
