Abstract

Kekeringan pada lahan sawah merupakan masalah yang kerap kali menjadi ancaman pada budidaya padi.Penggunaan varietas yang tepat dapat mengurangi resiko kehilangan hasil yang terlalu besar. Penelitian inibertujuan untuk mengetahui keragaan hasil 220 galur padi sawah generasi lanjut di lahan kering dibandingkandengan lahan optimal. Percobaan dilaksanakan pada musim kemarau di kebun percobaan BB Padi Sukamandi,menggunakan rancangan augmented 5 blok dengan 4 varietas pembanding (INPARI 10, INPARI 13, SituBagendit, dan Limboto). Perlakuan lahan optimal sesuai dengan cara budidaya yang disarankan, sedangkan lahankering hanya diairi hingga 4 minggu setelah tanam. Luas plot yang digunakan 1 m x 5 m per galur. Pengamatandilakukan terhadap umur berbunga 10% dan 50% (hss), tinggi tanaman (cm), jumlah anakan dan malai per rumpun,bobot seribu butir (gram), dan hasil per plot (kg) dikonversikan menjadi t/ha GKG. Pengamatan terhadap kondisiair tanah, kelengasan tanah, serta skoring gejala kekeringan ditambahkan untuk lahan kering. Sebanyak 23 galurmemperoleh hasil lebih baik dari Situ Bagendit (2,32 t/ha GKG) di lahan optimal dan 17 galur lebih baik dariLimboto (1,05 t/ha GKG) di lahan kering. Galur BP15704b-14 dan A 62-1 (BP10764f-10-2) teridentifikasi tumbuhbaik di kedua lahan. Tujuh galur dengan produktivitas setara Limboto mempunyai mekanisme ketahanan terhadapkekeringan. Kondisi kekeringan menurunkan tinggi tanaman, bobot seribu butir, dan hasil.Kata kunci: daya hasil, galur padi, lahan kering, kekeringanABSTRACTDrought often pose a threat to rice cultivation because water is an essential requirement in rice growth.Drought tolerant varieties are expected to mitigate the risks of drought stress. This study aims to determine theperformance of 220 advance lines in the dry land as compared with the optimum land. Experiment conducted atSukamandi esperimental station during dry season. Experiment was arranged in augmented 5 blocks with 4 checkvarieties (INPARI 10, INPARI 13, Bagendit, and Limboto). The optimum land treatment irrigated based on therecommended cultivation, while the dry land treatment irrigated until 4 weeks after planting only. The plot areawas 1 m x 5 m per lines. Observations was done for: days to 10% and 50% flowering (DAS), plant height (cm),number of tillers and panicles per hill, thousand grain weight (g), and yield per plot (kg) converted to t/ha. Additionobservations on dry land treatment was done for groundwater, soil moisture, and scoring drought symptom. Theresult showed 23 lines had higher yield than Situ Bagendit (2.32 t/ha) in optimum land, while 17 lines had higheryield than Limboto (1.05 t/ha) in dry land. BP15704b-14 and A 62-1 (BP10764f-10-2) was identified had stableyield on both treatment. Seven lines which similar with Limboto productivity was estimated to have resistancemechanisms for drought stress. Drought stress decline plant height, grain weight, and yield.Key words: potential yield, dry land, drought

Abstract

Penelitian ini bertujuan mengetahui pengaruh penggunaan beberapa jenis sitokinin dan beberapa levelkonsentrasi air kelapa terhadap respon pertumbuhan tunas mikro stevia. Rancangan Penelitian ini menggunakanRancangan Acak Lengkap (RAL), meliputi 3 jenis sitokinin (2 ppm Kinetin, 2ppm BAP, 2ppm TDZ) dan 4 levelkonsentrasi air kelapa (0%; 5%; 10%; 15%) dengan 5 ulangan. Parameter pengamatan meliputi persentasekontaminasi, persentase browning, saat muncul tunas, jumlah tunas, panjang tunas dan jumlah ruas. Data dianalisisdengan analisis ragam (ANOVA) dan uji DMRT pada taraf 5%. Hasil penelitian pada 30 HST untuk parametersaat muncul tunas, jumlah tunas, panjang tunas dan jumlah ruas, interaksi antara BAP dan air kelapa menunjukkanperbedaan yang tidak nyata. Namun hasil analisis menunjukkan pengaruh tunggal sitokinin dan air kelapa dalampembentukan dan pertumbuhan tunas. Media perlakuan dengan menggunakan MS+2ppm BAP tanpa air kelapaterbukti memacu kemunculan tunas lebih cepat, yaitu rata-rata 3,05 Hari Setelah Kultur (HSK) serta memacupertambahan jumlah ruas (2,6 ruas per tunas) dan tunas (3,7 tunas per eksplan). Penambahan air kelapamenghambat kecepatan pertumbuhan tunas. Parameter pertumbuhan tunas menunjukkan semakin besarkonsentrasi air kelapa yang ditambahkan semakin menurunkan pertumbuhan tunas baik dari jumlah, panjang atauruas.Kata kunci: Stevia, in vitro, air kelapa, sitokininABSTRACTThis study aimed to determine effect of use of several types of cytokinin and levels of coconut waterconcentration on stevia micro shoot growth response. This study was arranged in a Randomized Block Design,including 3 types of cytokines (2 ppm Kinetin, 2ppm BAP, 2ppm TDZ) and 4 levels of coconut water concentration(0%, 5%, 10%, 15%) with 5 replications. The parameters included percentage of contamination, percentage ofbrowning, time to form shoots, number of shoots, shoot length and number of nodes. Analyzed by variance analysis(ANOVA) and DMRT test at 5% level. For analysis results of time to form shoots, number of shoots, shoot lengthand number of segments showed that the interaction between BAP and coconut water gave no significantdifference. However, the results of the analysis showed a single effect of cytokinin and coconut water in shootformation and growth. Treatment media using MS + 2ppm BAP without coconut water proved to accelerate theappearance of shoot more rapidly, that is average 3.05 days after culture and induced the increase of the numberof node (2.6 node per shoot) and shoot number (3.7 shoots per explant). The addition of coconut water inhibitedthe growth rate of buds. Shoot growth of the number, length, and node number of shoots decline due to highconcentration of coconut water added further decrease the growth of shoot either from the number, length, andnode number of shoots.Key words: Stevia, in vitro, coconut water, cytokinins

Tujuan penelitian untukmengetahui dosis optimal pupuk kalium pada bawangmerah spesifik lokasi lahan pasir. Penelitian dilaksanakan selama dua musim kemarau pada bulan Juni-September2015 dan Juni-September 2016 di lokasi Kelompok Tani Manunggal, Desa Srigading, Kecamatan Sanden,Kabupaten Bantul (07o 59’ 8659” S, 110o 15’ 6753” E). Penelitian menggunakan Rancangan Acak Kelompokfaktor tunggal dengan pendekatan Minus One Test yang terdiri dari 7 taraf dan kontrol diulang 3 kali. Responpemupukan kalium menggunakan Rancangan Acak Kelompok dengan 5 perlakuan tingkat dosis 0, 75, 150, 225,dan 300 kg KCl/ha. Hasil penelitian menunjukkan bahwa status hara sebelum penelitian kandungan hara kalium(Kdd) 0.18-0.25 me K/100g-1 status hara sangat rendah (SR), sehingga menjadi faktor pembatas utama. Berdasarkanminus one test dosis pemupukan optimal bawang merah spesifik lokasi lahan pasir ialah KCl 150 kg ha-1 denganpersen hasil relatif tertinggi (120%). Akan tetapi respon dosis pemupukan kalium dosis maksimum 250 kg/ha-1dengan persamaan kuadratik (R2 = 0.556). Produksi bawang merah maksimal mencapai 15-16 t/ha-1 brangkasan(setara dengan 12.75-13.6 t/ha umbi) dengan rendemen umbi ±15%. Oleh karena itu, dalam implementasinyadiperlukan dosis kalium optimal secara spesifik lokasi, tidak dosis umum secara nasional.Kata kunci: lahan pasir, bawang merah, kalium, pupuk NPKABSTRACTPotassium is one of success key of soil nutrient on shallot production support on south sandy land.
