Water spinach is a heavy metal accumulator plant if grown in polluted soils. This raises the concern of water spinach safety as one of the most consumed vegetables in Asian household. Land pollution in water spinach cultivation area can be caused by industrial activities that involve heavy metals such as tannery. Industrial waste such as chrome leaches to the water system that eventually will be used as irrigation source for agriculture. Organic fertilizer is a potential solution to increase water spinach growth, yield, and absorb heavy metal contaminants. This research evaluated the effect of type and dosage of organic fertilizer on water spinach that grown in chromium-polluted soils. This research design used Randomized Block Design (RBD) with nine treatments and three replication. The treatment of combination of types and dosages of organic fertilizer. There were dried leaves, goat manure, and vermicompost with dosage of 5 t ha-1, 10 t ha-1 and 15 t ha-1. The results of this research showed that the effect of combination of organic fertilizer type and dosages at chrome polluted media gave better effect on growth, and yield of water spinach. Giving vermicompost of 15 t ha-1 gaves better effect on plant height, fresh weight of plant, and dry weight of plant, meanwhile the doses of 5 t ha-1dried leaves showed the lowest chrome content compared to other treatments, but these plants are still unsafe for consumption due to high chrome content.Keywords: water spinach, organic fertilizer, chromium, yield

Peanut, which is commonly planted in interculture and intercropping system, often suffers from shading caused by associated plants. This experiment aimed to study the effect of different shade levels of three peanut cultivars on the growth and seed yield, also to determine the shade-tolerant cultivar. A pot experiment was done at the Research Station of Agriculture Faculty Universitas Winaya Mukti since July until October 2016 by creating 50%, 65%, and 75% artificial shade levels during the lifetime of Tuban, Jepara, and Bima cultivars. The shade significantly affected on number of trifoliate leaves, number of branches, plant dry weight, yield components (number of pods, number of filled pods, and number of seeds), dry weight of pod, and seed weight per plant. The cultivar gave same effect on the growth and seed yield per plant. Based on Stress Tolerance Index (STI) analysis on the seed dry weight per plant, only Tuban cultivar showed great tolerance of 65% shade of natural light. Overall, the whole cutivars tested were sensitive on 75% shade level. ABSTRAKKacang tanah yang biasa ditanam pada sistem tumpangsari dan interkultur, sering ternaungi karena berasosiasi dengan tanaman lainnya. Penelitian ini bertujuan untuk mengkaji pengaruh naungan yang berbeda pada tiga kultivar kacang tanah terhadap pertumbuhan dan hasil, serta mendapatkan kultivar kacang tanah yang toleran terhadap naungan. Percobaan pot dilakukan di kebun percobaan Fakultas Pertanian Universitas Winaya Mukti dari bulan Juli sampai dengan Oktober 2016. Perlakuan percobaan adalah perbedaan naungan (tanpa naungan, naungan 50%, 65% dan 75%) selama siklus hidup tiga kultivar tanaman kacang tanah (Tuban, Jepara dan Bima). Hasil percobaan menunjukkan bahwa naungan memengaruhi jumlah daun trifoliat, jumlah cabang, bobot kering tanaman, komponen hasil (jumlah polong, jumlah polong isi, dan jumlah biji), bobot kering polong dan bobot kering biji per tanaman. Kultivar memberikan efek yang sama terhadap pertumbuhan dan hasil per tanaman. Berdasarkan analisis Stress Tolerance Index (STI) terhadap bobot kering per tanaman, hanya kultivar Tuban yang toleran pada naungan 65%. Semua kultivar peka terhadap naungan 75%.

Produktivitas lahan yang rendah disebabkan rendahnya ketersediaan hara akibat peran mikroba tanah yang menguntungkan bagi tanaman menurun. Penambahan bahan organik dan penggunaan pupuk hayati merupakan usaha untuk meningkatkan produktivitas tanah dan tanaman. Mikoriza Arbuskula (MA) merupakan salah satu pupuk hayati yang dapat meningkatkan produktivitas tanah dan tanaman. Percobaan rumah kasa dilakukan dengan tujuanuntuk mempelajari efek takaran pupuk kompos disertai inokulasi mikoriza terhadap pertumbuhan,kolonisasi mikoriza dan hasil tanaman kedelai. Percobaan menggunakan Rancangan Acak kelompok berfola faktorial dengan dua faktor dan dua ulangan. Faktor pertama yaitu takaran kompos terdiri dari tanpa kompos, 10 ton ha-1, 20 ton ha-1 dan 30 ton ha-1, sedangkan faktor kedua kedua yaitu takaran mikoriza terdiri atas tanpa mikoriza, 5 g, 10 g dan 15 g per lubang tanam. Hasil percobaan menunjukkan bahwa takaran kompos dan mikoriza memberikan efek yang berbeda terhadap jumlah polong, jumlah biji dan bobot biji kering per tanaman, tetapi tidak terhadap tinggi tanaman, jumlah daun dan jumlah nodula efektif per tanaman, nisbah pupus akar, kolonisasi mikoriza, dan bobot 10 butir. Hasil lebih tinggi diperoleh jika pemberian 30 ton ha-1 dan 20 ton ha-1 disertai dengan inokulan miroriza masing-masing 10 g dan 15 g per lubang tanam.
