Abstract

The research aimed to study the growth and yield of red spinach as affected by manures and giberelin. This research used monofactor experiment with Completely Randomized Design consist of 7 treatments and 3 replications. The treatments were T0 (control), T1 (GA3 100 ppm and cow manure 6,250 kg / ha), T2 (GA3 200 ppm and cow manure 12,500 kg / ha), T3 (GA3 300 ppm and cow manure 18,750 kg / ha), T4 (GA3 100 ppm and goat manure 3,750 kg / ha), T5 (GA3 200 ppm and goat manure 7,500 kg / ha), T6 (GA3 300 ppm and goat manure 11.250 kg / ha). Observed parameters were plant height, leaf number, leaf area, wet weight and dry weight. The data were processed by analysis of variance and further test with Duncan Multiple Range Test and Contrast Test. The best plant height growth was in the treatment of 18,750 kg / ha of cow manure and 300 ppm gibberellin resulted plant height of 21.11 cm. The highest number of leaves in the treatment of 11,250 kg / ha of goat manure and 300 ppm gibberellin resulted 21.44 leaves. Leaf area (528.79 cm2), fresh weight (68,50 g), and best dry weight (26.97 g) were achieved at 7,500 kg / ha goat manure treatment and 200 ppm giberelin. It was concluded that the application of manure and gibberellin increased plant growth (plant height, leaf number, leaf area), and crop production (fresh weight and dry weight) of red spinach. The combination of goat manure and giberelin was better than cow manure on all parameters. Goat manure of 7,500 kg / ha and 200 ppm gibberellin increased growth and production of red spinach on leaf area parameters, fresh weight, and dry weight. Keywords : red spinach, manure, gibberellin

Abstract

ABSTRACT  The purpose of this research was figured out of goat manure and FeSO4 by added concentrations of FeSO4 to growth and producton of red lettuce. It was done by using by 2x3 completely randomized design with 5 times. The first factor was goat manure (no goat manure and goat manure) and the second factor were various concentrations of FeSO4 (0 ppm, 2.0 ppm dan 2.5 ppm).. Parameters observed were plant height, fresh weight, chlorophyll, and betacarotene. The result showed that the treatment of goat manure gave more significant effect (p<0,05) compared with no goat mannure at plant height, fresh weight, and betacarotene but insignificant at chlorophyll. The treaments of FeSO4 (2 and 2.5 ppm) insignificant at all of parameters. Keywords : lettuce, goat manure, FeSO4 ABSTRAK  Penelitian ini bertujuan untuk mengkaji pengaruh penggunaan pupuk kotoran kambing dengan penambahan dosis FeSO4 terhadap pertumbuhan dan hasil tanaman selada merah. Penelitian disusun dengan percobaan faktorial 2x3 rancangan acak lengkap 5 ulangan. Faktor pertama adalah pupuk kotoran kambing (kontrol dan pupuk kotoran kambing) dan faktor kedua adalah konsentrasi FeSO4 (0 ppm, 2.0 ppm dan 2.5 ppm). Parameter yang diamati yaitu, tinggi tanaman, berat segar, klorofil, dan betakaroten. Hasil penelitian menunjukkan bahwa perlakuan pemberian pupuk kandang memberikan hasil yang nyata (p<0,05) lebih tinggi dibanding tanpa pupuk kandang terhadap tinggi tanaman, berat segar, dan betakaroten, tetapi tidak nyata pada klorofil. Pada perlakuan FeSO4 2 dan 2.5 ppm tidak menunjukkan pengaruh nyata terhadap semua parameter. Kata kunci : Selada, pupuk kotoran kambing, FeSO4

Abstract

ABSTRACT  The aim of this research was to observe of subtitution of inorganic fertilizer with organic herbs fertilizer on growth and production of tomato plants. The research used Monofactor Completely Randomized Design with 3 replications. The treatment that substitution of inorganic fertilizer with organic herbal fertilizer were 100%+0% (T0); 80%+20% (T1); 60%+40% (T2); (T3) 40%+60% (T3);20%+80% (T4); 0%+100% (T5). Parameters observed were plant height, number of leaves, number of flowers, number of fruit and weight of fresh fruit. Data were analysis of variabel (F Test) and further test with Tukey Multiple Range Test (BNT). The results showed that the substitution of fertilizer on treatment T3 (40% of inorganic fertilizers + 60% organic herbal fertilizer) can give number of leaves, number of flowers, number of fruit and weight of fresh fruit higher than compared with the other treatment. However, no significant effect on plant height. Keywords: Tomato varieties of permata, organic herbal fertilizer, dosage ABSTRAK  Penelitian bertujuan untuk mengetahui pengaruh substitusi pupuk anorganik dengan pupuk herbal organik terhadap pertumbuhan dan produksi tanaman tomat. Penelitian menggunakan percobaan Monofaktor Rancangan Acak Lengkap dengan 3 ulangan. Perlakuan yang diberikanadalah substitusi pupuk anorganik dengan pupuk herbal organik yaitu 100%+0% (T0); 80%+20% (T1); 60%+40% (T2); (T3) 40%+60% (T3);20%+80% (T4); 0%+100% (T5). Parameter yang diamati yaitu tinggi tanaman, jumlah daun, jumlah bunga, jumlah buah dan berat buah segar. Data diolah dengan analisis ragam (Uji F) dan uji lanjut denganBeda Nyata Terkecil (BNT).Hasil penelitian menunjukkan bahwa substitusi pupuk pada perlakuan T3(40% pupuk anorganik + 60% pupuk herbal organik) dapat menghasilkan jumlah daun, jumlah bunga, jumlah buah dan berat segar buah tomat lebih tinggi dibandingkan dengan perlakuan lainnya. Namun tidak berpengaruh nyata terhadap tinggi tanaman. Kata kunci: tomat varietas permata, pupuk herbal organik, dosis

Abstract

Problems in the cultivation of plants pakchoy caused by the influence of the physical environment such as climate, wind, temperature, the intensity of solar radiation, humidity, and soil. The research aims to know types of mulch and patterns of the plant spacing for optimizing on growth and yield of pakchoy. This experiment had been conducted in the experimental field Margahayu, Balai Penelitian Tanaman Sayuran, Lembang on September-November 2016. The design of the research which used was randomized block design factorial with 9 treatment combinations and 3 replications. The first factor is “Types of Mulch”, the use of M0 (no mulch), M1 (black silver plastic mulch), and M2 (rice straw mulch). The second factor is “The Plant Spacing Patterns”, which are J0 (10x10 cm_triangle), J1 (20x20 cm_square), and J2 (30x30 cm_hexagonal). Data was analyzed with analysis of variance (ANOVA) and continued with Duncan Multiple’s Range Test (DMRT) at α=5%. The result showed that the use of black silver plastic mulch and spacing pattern of 20x20 cm (square) is a combination of the best treatment because it has the fresh weight of the canopy and the fresh weight of the roots of the most highest when compared to treatment with a combination of other, namely fresh weight of canopy 5,02 kg and weight of fresh roots 253,6 g.
