Agronomic Performance of Chrysanthemum Varieties in Bandung. The objective of this experiment was to determine the agronomic performance of chrysanthemum varieties in Bandung Regency. The experiment was conducted at District Pasir Jambu Bandung regency of West Java Province on July until October 2010. The materials used are 10 varieties of chrysanthemum: Puspita Nusantara, Padma Buana, Puspita Asri, Purbasari, Swarna Kencana, Cut Nyak Dien, Sakuntala, Tirta Ayuni, Candra Kirana, and Mustika Kaniya. Fertilizers used were fermented manure 30 t / ha, urea 200 kg / ha, SP36 300 kg / ha, and KCl 250 kg / ha, foliar fertilizer Gramoxone 1 cc / l, and pesticides. Randomized block design with ten treatment ofchrysanthemum and four replications. The results of experience conclused that Swarna Kencana, Sakuntala and Padma Buana has a plant height 100.5 cm, 97.6 cm, and 94.76 cm higher than the other varieties (grade A) and the shortest are Candra Kirana of 51.95 cm (grade C). The number of stem segments occurred of Tirta Ayuni varieties in 32.5 and varieties Purbasari 26.2 lowest. Mustika Kaniya has the largest trunk diameter (0.74 cm) and smallest diameter occur on Padma Buana (0.45 cm), Purbasari (0.45 cm) and Puspita Asri (0.46 cm). Tirta Ayuni have leaf length (13.74 cm) and petiole length reached (4.05 cm). The diameter of the largest flower is Sakuntala and the smallest is Candra Kirana. The number of flower Candra Kirana was the smallest (7.7 buds) and most of flowers Purbasari namely 27.30 buds.

The increme of Wetland Rice Production with New High Yieldding Varieties The use of high yielding variety (HYV) is one of the technology components that supports rice production, besides fertilizer and irrigation. Yet the use of HYV is still slowly adopted, resulting in continuing previous varieties application. The objectives of the research were to determine the HYV with the highest yield implementing integrated crop management (ICM). The location of research was in Tanjung Sari village, Pondok salam subdistrict, Purwakarta residence in 2009 dry season. The new seven HYVs (Inpari 1, Inpari 2, Inpari 3, Inpari 4, Inpari6, Inpara 2, and Aek Sibundong) were treated with randomized complete block design (RCBD) with four replications. The results showed that Aek Sibundong variety had the highest crop height, the number of panicle per hill, and the filled grain percentage. Aek Sibundong variety had 11.7 t/ha grain yield, while that Inpari 2 had 8.26 t/ha. There were significant correlation between dry yield and the number of panicle per hill and the number of grain per panicle, with the value of 4.470 and 0.479, respectively.

Pupuk anorganik yang terus menerus diberikan pada setiap musim tanam padi dapat mencemarilingkungan selain produktivitas lahan menurun dan berpengaruh juga terhadap produktivitas padi menjadirendah. Oleh karena itu, dalam upaya meningkatkan produktivitas padi selain memberikan pupuk anorganikdiperlukan penambahan mikroba probiotik lokal seperti Agri Simba yang mampu memperbaiki kesuburan tanahsehingga penggunaan pupuk kimia berkurang. Pengkajian ini bertujuan untuk mengetahui pengaruh penggunaanAgri Simba terhadap pertumbuhan, komponen hasil dan hasil padi sawah varietas Inpari 1. Pengkajianmenggunakan rancangan acak kelompok (RAK) dengan empat ulangan. Perlakuan Agri Simba disusunberdasarkan tingkat pemberian takaran 5; 10; 15; dan 20 l/ha. Hasil pengkajian menunjukkan bahwa pemberianAgri Simba berpengaruh baik pada pertumbuhan tinggi tanaman. Hasil gabah kering tertinggi dicapai padatingkat pemberian 10 l/ha Agri Simba sebanyak 11,20 t/ha GKG, dan terendah diperoleh pada takaran 5 l/ha AgriSimba sekitar 10,05 t/ha GKG. Hasil gabah kering giling maksimum dicapai pada tingkat pemberian 12,81 l/haAgri Simba.

Penelitian bertujuan untuk mengetahui pengaruh pemberian pupuk kalium pada pertumbuhan dan hasilserta untuk mendapatkan dosis pupuk kalium yang memberikan hasil maksimum pada ubi jalar varietasNarutokintoki. Penelitian dilaksanakan dilahan sawah musim kemarau tahun 2008 di Desa Wanasari, KecamatanWanayasa Kabupaten Purwakarta, Jawa Barat. Pupuk kalium sebagai perlakuan disusun berdasarkan RancanganAcak Kelompok dengan empat perlakuan dan enam ulangan. Perlakuan terdiri dari : pupuk kalium dengan dosis60, 120, dan 180 kg K2O/ha dan tanpa pupuk K (kontrol). Ubi jalar yang digunakan adalah varietasNarutokintoki. Hasil penelitian menunjukkan bahwa penggunaan pupuk kalium memberikan pengaruh yangnyata terhadap panjang sulur, berat hijauan, jumlah umbi, berat umbi dan hasil ubi. Pada pemupukan kaliumdengan dosis 120 kg/ha K2O dapat meningkatkan hasil ubi sebesar 10,55 t/ha. Peubah yang memberikan korelasinyata dengan hasil ubi jalar yaitu peubah jumlah umbi per rumpun dan berat umbi per rumpun dengan nilai rmasing-masing sekitar 0,680* dan 0,789*. Hubungan hasil ubi jalar dengan tingkat pemupukan kaliummembentuk regresi kuadratik nyata dengan model persamaan Ŷ = 5,255 + 251 X - X², R2 = 0,90*. Padapersamaan ini untuk mendapatkan hasil optimum ubi jalar varietas Narutokintoki diperoleh pada dosis 125,5 kgK2O/ha.Kata kunci: pupuk kalium, ubi jalar, lahan sawah ABSTRACTThe study aims to determine the effect of potassium fertilizer on growth and yield and to get a dose ofpotassium fertilizer that gives optimum results in sweet potato Narutokintoki varieties. The experiment wasconducted in 2008 dry season at rice field of Wanasari village, Wanayasa District, Purwakarta Regency, WestJava. Potassium fertilizer as treatments have been prepared on randomized block design with four treatmentsand six replications. Treatments consisted of: potassium fertilizer with doses of 60, 120, and 180 kgs K2O ha-1and without K fertilizer (control). Sweet potato used were Narutokintoki varieties. The results showed that theuse of potassium gives a real influence on the long shoots, foliage weight, tuber number, tuber weight and tuberyield. At a dose of potassium fertilization of 120 kgs K2O ha-1 can increase tuber yield into 10.55 tha-1. Variablesthat provide real correlation with the results is variable number of tubers per hill and tuber weight per hill withrespective r values around 0.680* and 0.789*. Relations between tuber yield and potassium fertilization ratewas significantly quadratic regression model equation Y = 5.255 + 251 X - X ², R2 = 0.90 *. In this equation toobtain optimum on tuber yield of Narutokintoki varieties was obtained at doses of 125.5 kgs K2O ha-1.Key words: K fertilizer, sweet potato, kice field
