Abstract

The purpose of the research was to study the effect of shade percentage and different harvest timeon stevia growth and production in lowland. The experiment was assigned in completely randomized multilocation design with the first factor was shade percentage (45%, 55% and 65%) and the second factor was different harvest time (30 DAP, 40 DAP and 50 DAP). Each treatments was repeated three times. Parameters measured were the plant height, dry weight, total chlorophyll content and total sugar content. Data were subjected to ANOVA and followed by Tukey Test. The result showed that the best shade percentage was 45% in total sugar content. The best harvest time was 50 DAP that showed on total chlorophyll content. The result showed no significant different on average plant height and dry weight. Interaction of shade percentage and different harvest time showed significant effect on total sugar content. Keyword : Stevia, shade percentage, harvest age

Abstract

The aim of this research was to observe the effect of abbit urine fertilizer based on Local Microorganism (LoM) with different type and dosage on growth and production of mustard. The research was conducted on 2nd June to 31st August 2017 at Greenhouse of Faculty of Animal and Agricultural Science Diponegoro University, Semarang. The research was design at 3x3 factorial design with 3 replications for each. The first factor was different type of rabbit urine fertilizer .ie. non fermented rabbit urine fertilizer (A1), rabbit urine fertilizer fermented of LoM glutinous tapai (A2), rabbit urine fertilizer fermented of LoM cassava tapai (A3) and the second factor was N dosage .ie. 150 kg/Ha (B1), 175 kg/Ha (B2), and 200 kg/Ha (B3). The observed parameters were plant N uptake, plant height, fresh weight production and dry weight production. The results of the study showed that the type and dosage of rabbit urine fertilizer did not affect of the growth and the production of mustard because the amount of N that can be utilized by the plant was relatively similar, probably due to the low C/N ratio causing the relative N easily to lose because of evaporation and the leaching process. It can be concluded that rabbit urine fermented and non fermented with different of dosage did not give significant effect on growth and production of mustard. Therfore, it is more advantageous to use non fermented rabbit urine fertilizer with 150 kg/ha dosage because of time saving and lower cost. Keywords : mustard, rabbit urine, Local Microorganism (LoM), tapai, dosage.

Abstract

  Penelitian bertujuan untuk mengkaji respon pertumbuhan tanaman kedelai, produksi dan kualitas kedelai pada tanah yang tercemar logam nikel yang diberi biokompos.Penelitian dilakukan di Rumah Kasa dan Laboratorium Terpadu BALINGTAN (Balai Penelitian Lingkungan Pertanian) Pati, Jawa Tengah dari bulan November 2018 – Februari 2019. Rancangan dasar yang digunakan dalam penelitian ini adalah rancangan acak lengkap pola faktorial 5 x 3 dengan 3 ulangan.Faktor pertama yaitu perlakuan konsentrasi cemarannikel (Ni) 0, 25, 50, 75, 100 ppm dan faktor kedua yaitu perlakuan dosis biokompos 0 ton/ha, 3,5 ton/ha dan 7ton/ha. Data dianalisis dengan analisis ragam dan dilanjutkan dengan uji berganda Duncan (Duncan’s Multiple Range Test). Hasil penelitian menunjukkanbahwa pada tanah yang diberi biokompos kurang dari 7 ton/ha dan semua tingkat cemaran menunjukkan penurunan pertumbuhandan produksi kedelai. Tanah yang diberi biokompos 7 ton/ha pada perlakuan konsentrasi cemaran nikel 25 ppm menghasilkan produksi kedelai (jumlah polong isi) setara atau sama dengan tanah tanpa cemaran nikel. Konsentrasi nikel dalam biji kedelai pada tanah yang tercemar nikel 25 ppm dengan diberi biokompos 7 ton/ha masih berada diatas ambang batas yang diijinkan. Kata kunci: kedelai, cemarannikel, biokompos

Abstract

This research aimed to observe the response of different incubation period and dosage of liquid organic fertilizer (LOF) based on vegetable and fruit local microorganism on cherry tomato growth and production. This research was conducted at Operational Greenhouse, Balai Benih Pertanian Kota Semarang Gunung Pati, Semarang. The research was conducted by 3x3 factorial experiments with 3 replications. The first factor was 6, 12, 18 days of incubation period and the second factor was 120, 240, 360 ml/plant dosage of LOF. The observed parameters were fruit N uptake, plant height, fruit diameter and fruit fresh weight. Results of study showed that both treatments had no significant effect on fruit diameter and fruit fresh weight caused by lack of P in LOF so that the overall fruit production was not optimum. Interaction between both treatments showed significant effect on fruit N uptake when on short incubation period, the dosage used was higher and vice versa. Six days of incubation with 240 ml/plant dosage gave the highest efficiency on improving fruit N uptake. Incubation period has no significant effect but the dosage of 360 ml/plant significantly gave optimum effect on plant height in comparison with dosage of 120 and 240 ml/plant. This research can be concluded that LOF with 6 days of incubation with dosage used between 240-360 ml/plant was efficient to improve growth of cherry tomato plant and addition of fertilizer was needed to improve production of cherry tomato. Keywords : Cherry tomato, LOF incubation period, LOF dosage

ABSTRACT  This research aimed to identify the effect of fertilizer type and concentration of AB Mix substitution with fertilizer on growth and yield of red lettuce (Lactuca sativa var. crispa). The research was conducted at Greenhouse of Crops, Horticulture and Plantation Protection Institute, Central Java. The method of this research is Randomized Complete Design Factorial 2 x 5 with 3 replications. First factor is fertilizer type, consist of A1: Azolla extract and A2: gamal leaves esxtract. Second factor is concentration of AB Mix substitution with fertilizer, consist of B0: 0%, B1: 25%, B2: 50%, B3: 75% and B4: 100%. The observed parameters were plant height, number of leaves, root length, crop growth rate, plant yield and plant dry weight. Data were processed by Analysis of Variance and continued by Duncan’s Multiple Range Test (DMRT). The result showed that there is interaction effect on plant height and plant yield. The conclusion is treatment of AB Mix substitution with Azolla extract fertilizer 25% and gamal leaves extract fertilizer 25% have same result with treatment without substitution on vegetative growth of red lettuce. Treatment of AB Mix substitution with Azolla extract fertilizer 50% and gamal leaves extract fertilizer 25% have same result with treatment without substitution on yield of red lettuce.Keyword: Azolla, gamal leaves, hydroponic, red lettuce. ABSTRAK  Penelitian bertujuan untuk mengkaji pengaruh jenis pupuk dan konsentrasi subtitusi AB Mix dengan pupuk terhadap pertumbuhan dan produksi selada merah (Lactuca sativa var. crispa).

Abstract

Penelitian bertujuan untuk mengkaji pertumbuhan dan toleransi tanaman kedelai akibat pemberian cemaran logam berat besi dengan beberapa konsentrasi dan pemberian pupuk kompos. Penelitian dilakukan di Rumah Kasa dan Laboratorium Terpadu BALINGTAN (Balai Penelitian Lingkungan Pertanian) Pati, Jawa Tengah dari bulan September - Desember 2017. Rancangan dasar yang digunakan dalam penelitian ini adalah rancangan acak lengkap pola faktorial 4x2 dengan 3 ulangan. Faktor pertama yaitu perlakuan konsentrasi ion logam besi (Fe) 0, 100, 200, 300 ppm, dan perlakuan pemberian pupuk kompos 0 kg dan 1 kg sebagai faktor kedua. Hasil penelitian menunjukkan bahwa fase pertumbuhan (tinggi tanaman dan waktu berbunga) pada perlakuan pemberian kompos (1 kg) memberikan pengaruh lebih baik di bandingkan dengan tanpa pemberian kompos (0 kg) pada berbagai konsentrasi cemaran besi. Tanaman kedelai dengan perlakuan tanpa pemberian kompos (0 kg) pada semua konsentrasi cemaran logam mati pada saat proses pembentukan polong. Perlakuan pemberian kompos 1 kg dapat mempertahankan produksi kedelai pada konsentrasi cemaran besi 100 ppm tetapi mengalami penurunan pada konsentrasi 200 ppm dan 300 ppm, serta pemberian kompos pada cemaran konsentrasi 100–300 ppm belum mampu menurunkan kandungan besi biji tanaman, nilainya masih diatas batas ambang yang diijinkan. Kata kunci: kedelai, logam besi, kompos
