Abstract

This study aims to obtain a doses of biological fertilizer and calcium doses that gives the best effect on the growth and production of beans (Phaseolus vulgaris L.) upright type. This experiment was carried out from February until April 2014, at the experimental field of Depatment of Agrotechnology, University of Djuanda Bogor. The experimental design used is a factorial completely randomized design with 5x3 treatments and 3 replications. The first factor biofertilizers (rich bio), A0: control (without biofertilizer), A1: Biological Fertilizer doses of 10 kg / ha, A2: biological fertilizer doses of 20 kg / ha, A3: biological fertilizer dose of 30 kg / ha, A4: microbial doses (as recommended), while the second factor doses of dolomite (CaMg (CO3) 2) consists of: B0: 0 ton / ha (without calcium), B1: 2 tons / ha, B2: 4 tons / ha. The results showed a doses of calcium 4 tons / ha showed a better response in plant height (2 weeks after plant) and the weight of the third harvest pod. Provision of calcium which is accompanied by adequate dosage of biological fertilizer can increase the wet weight and dry weight of stover.  Keywords: bean seed upright type, dosage biological fertilizer, calcium

Abstract

Lettuce (Lactuca sativa L.) is a widely known leave vegetable.  This vegetable is so rich in nutrient contents particularly vitamins and minerals that people can consume it to meet their nutrient requirements.  This study was aimed at assessing the effects of sea grass organic fertilizer administration on the growth and production of lettuce.  The study was conducted at the trial farm of Department of Agrotechnology, Faculty of Agriculture, Djuanda University, Bogor from March to April 2014.  A completely randomized design with two factors consisting of lettuce variety (V) and sea grass organic fertilizer (R) was used.  The varieties of lettuce consisted of curly lettuce (Lactuca sativa var. New grand rapid) (V1) and red lettuce (Lactuca sativa var. new red fire) (V2).  Sea grass organic fertilizer (R) was given in three levels, namely no fertilizer (R0), 500 kg/ha (0.5 recommended rate) (R1), 1000 kg/ha (1.0 recommended rate) (R2),  1500 kg/ha (1.5 recommended rate) (R3), and 2000 kg/ha (2.0 recommended rate) (R4).   Keywords: lettuce variety, sea grass organic fertilizer, growth and production.

Abstract

This study was conducted at the experiment garden of Agrotechnology Department, DjuandaUniversity, Bogor, from July to September 2018. The study was aimed at assessing the effects ofthe application of nitrogen fertilizer and mung bean sprout extract on the growth and productionof edamame (Glycine max L. Merril) plants. The experimental design used was a factorialcompletely randomized design. The first factor is the dose of N fertilizer with four levels, namelywithout N (0 kg N / ha), a half recommendation of N fertilizer (34.5 kg N / ha), one recommendationof N fertilizer (69 kg N / ha), and one and a half recommendation of N fertilizer (103.5 kg N / ha).The second factor is the concentration of mung bean sprout extract with four levels, namely withoutmung bean sprout extract (0g tauge extract / l water), a half recommendation of mung bean sproutextract (75g tauge extract/ l water), one recommendation of mung bean sprout extract (150g taugeextract / l water) and one and a half recommendation of mung bean sprout extract (225g taugeextract/ l water). The results showed that the dose of N fertilizer significantly affected the widestleaf area. The concentration of mung bean sprout extract significantly affected the number of shootsat 6 and 7 weeks after planting (MST).Keywords: edamame soybean, N fertilizer, mung bean sprout

Abstract

Antraknosa merupakan salah satu penyakit utama yang menyerang tanaman cabai merah (Capsicum annuum L.) sehingga dapat menurunkan produktivitas. Penggunaan fungisida nabati dan mikroorganisme dapat mengurangi persentase serangan antraknosa pada cabai merah tanpa menimbulkan dampak negatif terhadap lingkungan. Penelitian ini bertujuan yaitu untuk mengetahui potensi larutan daun mimba dan MOL bonggol pisang dengan dosis yang tepat dalam mengendalikan penyakit antraknosa serta meningkatkan pertumbuhan dan hasil pada tanaman cabai merah. Model penelitian yang digunakan yaitu Rancangan Acak Kelompok Faktorial yang terdiri atas dua faktor yaitu konsentrasi larutan daun mimba (0%, 15%, 30%, 45%) dan konsentrasi MOL bonggol pisang (0%, 15%, 30%, 45%). Hasil penelitian menunjukkan bahwa konsentrasi larutan daun mimba tidak memberikan pengaruh yang nyata terhadap semua peubah yang diamati. Konsentrasi larutan MOL bonggol pisang 45% berpengaruh nyata dalam meningkatkan tinggi tanaman, jumlah daun, jumlah cabang produktif dan bobot buah per tanaman dibandingkan dengan perlakuan kontrol, namun tidak berbeda nyata dibandingkan dengan konsentrasi 30%. Pada penelitian ini tidak terjadi serangan antraknosa terhadap semua tanaman yang diamati pada semua perlakuan, artinya persentase kejadian penyakit dan tingkat keparahan penyakit adalah 0%. Hal tersebut terjadi diduga karena faktor lingkungan yang tidak mendukung untuk perkembangan jamur Colletotrichum sp.

Abstract

Tujuan penelitian untuk memahami pengaruh pemberian ekstrak Azolla pinnata dan lama perendaman benih pada air kelapa terhadap pertumbuhan dan hasil tanaman kacang tanah. Percobaan menggunakan rancangan acak lengkap (RAL) faktorial. Dosis Azolla pinnata terdiri atas empat taraf: 0%, 1%, 1.5%, dan 2% masa media tanam (mmt). Lama perendaman benih dengan air kelapa terdiri atas empat taraf yaitu direndam selama 0 jam, 6 jam, 12 jam, dan 24 jam. Dosis pemberian Azolla pinnata pada media tanam dan lama perendaman benih dalam air kelapa memberikan pengaruh positif pada pertumbuhan tinggi tanaman, jumlah daun, luas daun, bobot segar dan kering tajuk, bobot segar akar, jumlah polong, persentase polong isi, dan jumlah bintil akar. Azolla pinnata dapat menjadi pupuk alternatif, dan air kelapa dapat berfungsi sebagai zat pengatur tumbuh alami.

Abstract

Lettuce growth and production are influenced not only by cultivars but also by the environment and their interaction. Providing nutrition is part of cultivation techniques that can affect plant cultivars' growth, production and quality. Sources of plant nutrition can come from natural materials, one of which is eggshells. This research aimed to determine the effect of eggshell fertilizer on the growth, production and quality of several varieties of loose-leaf lettuce. The research was conducted from March to May 2022 in Gunung Putri, West Java. It was designed using a factorial, completely randomized design with three replications. Eggshell fertilizer consists of 5 levels, namely without eggshell fertilizer treatment, 50% recommendation (5 g per plant), 100% recommendation (10 g per plant), 150% recommendation (15 g per plant), and 200% recommendation (20 g per plant). Observed variables include growth, yield and quality characteristics. The Karina lettuce variety generally has superior growth and yield compared to the Kreibo variety but has relatively no differences from the New Grand Rapid variety. The Karina variety treated with eggshell fertilizer had a larger stem diameter than the one not treated with eggshell fertilizer. The Karina variety treated with eggshell fertilizer up to 200% has a higher dry weight and PTT content. The Karina variety, given the recommended 200% eggshell fertilizer, and the New Grand Rapid variety, given the recommended 100% eggshell fertilizer, produced the crispiest leaves. Eggshell fertilizer can potentially increase crop yields and quality, but further testing is needed to make it more optimal.
