Duku mempunyai perakaran yang dalam, sehingga sulit untuk memperoleh sampel tanah yang representatif pada daerah tersebut, sehingga lebih tepat menggunakan analisis daun. Status hara daun merupakan gambaran status hara aktual dalam tanah. Penelitian bertujuan untuk menentukan kategori status hara N, P, dan K, serta rekomendasi pemupukan optimum berdasarkan status hara tersebut pada tanaman duku. Penelitian dilaksanakan di Kecamatan Kumpeh Ulu, Kabupaten Muaro, Jambi pada Bulan Desember 2008 sampai dengan April 2012. Â Rancangan penelitian menggunakan acak kelompok dengan lima ulangan. Â Perlakuan dosis pupuk N (0, 400, 800, 1.200, dan 1.600 g N) , P (0, 500, 1.000, 1.500, dan 2.000 g P2O5), K (0,600, 1.200, 1.800, dan 2.400 g K2O/tanaman/tahun). Hasil penelitian menunjukkan bahwa status hara N sangat rendah (< 1,81%), rendah (1,81 â¤ N < 2,82%), dan sedang (â¥ 2,82%), status hara P sangat rendah (< 0,09%), rendah (0,09 â¤ P < 0,17%), dan sedang (â¥ 0,17%), serta status hara K sangat rendah (< 1,16%), rendah (1,16 â¤ K < 2,19%), dan sedang (â¥ 2,19%). Â Rekomendasi pemupukan pada tanaman duku untuk status hara sangat rendah yaitu 858 g N, 1.770 g P2O5, dan 1.900 g K2O/tanaman/tahun, untuk status hara rendah, 588 g N, 1.335 g P2O5, dan 1.107 g K2O/tanaman/tahun, sedangkan berdasarkan pendekatan multinutrien 920 g N, 1.565 g P2O5, dan 1.488 g K2O/tanaman/tahun (biaya produksi terendah). Rekomendasi pemupukan N, P, dan K berdasarkan analisis daun dapat diterapkan pada pertanaman duku di Indonesia dan meningkatkan produksi serta kualitas buah duku.Â Duku has been deep roots making it difficult to obtain a representative sample of soil at the root zone, so the more appropriate used of leaf analysis.

Hoya diversifolia Blume merupakan salah satu anggota famili Asclepiadaceae yang potensial dikembangkan sebagai tanaman hias, terutama sebagai dekorasi pergola. Akan tetapi, tanaman ini hidup pada kondisi ternaung di habitat aslinya dan pertumbuhannya pada kondisi cahaya matahari penuh belum diketahui. Oleh karena itu, tujuan dari penelitian ini adalah untuk mempelajari adaptasi tanaman H. diversifolia Bl. pada intensitas cahaya yang berbeda. Penelitian disusun berdasarkan rancangan tersarang, dengan satu faktor dan tiga ulangan. Ulangan tersarang di dalam intensitas cahaya yang terdiri atas tiga taraf, yaitu 28.2 (cahaya penuh), 20.8 (37% naungan) dan 10.1 Klux (64% naungan). Hasil penelitian menunjukkan bahwa tinggi tanaman dan jumlah daun tidak dipengaruhi oleh intensitas cahaya. Tanaman yang ditanam pada kondisi cahaya penuh memiliki jumlah buku lebih sedikit, daun yang lebih tipis, dan warna daun yang kekuningan. Hasil penelitian ini mengindikasikan bahwa H. diversifolia Bl. dapat ditanam pada kondisi naungan hingga ternaung sebagian, dan menanam pada kondisi cahaya matahari penuh tidak direkomendasikan. Kata kunci: Asclepiadaceae, intensitas cahaya, naungan, tanaman hias

Common bean is a type of vegetable that can be consumed in the form of young pods. Potassium is one of the macronutrients needed to achieve maximum yield in common bean. Therefore this research is aimed at determining a suitable potassium source as well as an appropriate rate for drip irrigation in common bean using polyethylene mulch. The study was conducted from January to May 2018 at University Farm, IPB University. This experiment was set up as a nested randomized block design with two factors i.e. potassium sources as the main factor ( KCl, ZK, and NPK), and potassium rates (0, 37.5, 75, 112.5, 150 kg of K2O per ha). Fertilizer rates were nested in the main factor and fertilizers were applied Fertilization through a drip irrigation fertigation system with emitters placed close to the roots of plants. Fertilizer sources had significant effects on the variables of growth and bean yields. NPK resulted in a better growth and yield compared with KCl and ZK. Fertilizer sources that have very significant effect were likely related to the shape and solubility of the fertilizers, the ease of application, and also completeness of nutrient content in fertilizer. Based on the pod weight per plot, the productivity per hectare of bean pods produced in this study reached 7.52 ton.ha-1. Potassium (K2O) rate did not have significant effects on the variables of growth and yields of the bean.

The increasing popularity of leaf and fruit of African nightshade as vegetables in Indonesia stimulates farmers to harvest both leaf and fruit from single plant alternately; the yield is presumably affected by fertilizer rate, e.g., nitrogen. The present study aimed to evaluate such hypothesis through evaluation of plant production, N absorption, and its status. Seedlings were treated with five N levels, i.e., 0, 90, 180, 270, and 360 kg/ha in Leuwikopo Experimental Farm, IPB Bogor, Indonesia. The results revealed that leaf and fruit productions were sensitive to nitrogen level. Leaf and fruit productions had quadratic correlation to N levels, i.e., r 2=0.9671 and r 2=0.9483 with optimum dosages as 304.8 kg/ha and 336.5 kg/ha, respectively. Proper N application is important for both leaf and fruit productions because nitrate level in leaf had quadratic relationship (r 2=0.5264) and it has a linear relationship in fruit production (r2=0.9587) by increasing N level from 90 to 360 kg N/ha. From the total fresh mass leaves and fruits harvested, the optimum N for the best alternate harvesting was 271.1 kg/ha (r 2=0.9644).

Gejala daun keriting kuning pada cabai telah dilaporkan di Pulau Bali sejak awal tahun 2012 dan saat ini semakin meluas. Penelitian dilakukan untuk mengidentifikasi penyebab penyakit dan daerah sebarnya di Pulau Bali. Penelitian diawali dengan pengamatan keparahan penyakit dan pengambilan sampel lapangan dari beberapa daerah penanaman cabai di Bali (Karangasem, Bangli, Tabanan, dan Gianyar). Identifikasi Begomovirus dari sampel lapangan dilakukan dengan metode polymerase chain reaction menggunakan primer universal SPG1/SPG2 dan dilanjutkan dengan analisis sikuen DNA target yang telah diamplifikasi. Insidensi penyakit daun keriting kuning cabai mencapai 100% pada semua lokasi pengamatan dan keparahan penyakit berkisar antara 18%−87%. Fragmen DNA spesifik Begomovirus berukuran 912 pb berhasil diamplifikasi dari 12 sampel lapangan. Analisis sikuen fragmen DNA menunjukkan homologi tertinggi dengan Pepper yellow leaf curl Indonesia virus (PYLCIV). Analisis filogenetik lebih lanjut mengonfirmasi hubungan kekerabatan antara isolat-isolat PYLCIV dari Bali dengan berbagai isolat PYLCIV dari Indonesia.
