Abstract

This studyaimed todetermine the influence of P fertilizer on the growth of mycorrizhal rubber seedlings (Havea brasilliensis. Muell, Arg) of PB 260 stum eye clones. The research was carried out in Pagaranri Pargarutan Village, East Angkola Sub District, South Tapanuli District, North Sumatera. It was conducted during January to April 2012 and arranged ina randomized block design with five rates of P fertilizeras treatments i.e 0, 5, 10, 15, 20 g plant-1. The results showed that the effect of P fertilizer was not significant on plant height, stem diameter, number of stems and leaf area but significant on dry weight of roots. Highest root weight was 472.69 mg found inno P fertilizer treatment with the my cor rizhal infection rate was 100%. This infection rate was the same with that in the 5 g P fertilizer rate treatment.

Abstract

This study aims to determine the effect of various concentrations of leaf fertilizer on red chili (Capsicum annum L.) of the Laju F1 variety cultivation. This research was conducted at the experimental garden Instalasi Penelitian dan Pengkajian Teknologi Pertanian Balai Penelitian Tanaman Sayuran Serpong (IP2TP Balitsa Serpong). The method used in this research was the experimental method of Randomized Block Design with one factor, namely giving various levels of concentration leaf fertilizer consisting of six treatment levels namely 0; 1; 2; 3; 4; and 5 g/l with a total of 5 replication to obtain 30 experimental units. The results showed that leaf fertilizer has a significant effect on the average plant height parameter at 5 weeks after planting (WAP) (53.12 cm); stem diameter 3 WAP (3,99 mm), 4 WAP (6.85 mm), and 5 WAP (8.87 mm); fruit length per plant at 2nd harvest (15.55 cm); and fruit diameter per plant at 1st harvest (9.26 mm) and at 2nd harvest (9.77 mm); fruit weight per plant (1157,54 g); and fruit weight per plot (2673,34 g). The treatment of various concentrations of leaf fertilizers showed no significant differences in the parameters of the amount of fruit per plant.

Abstract

The research was aimed to determine the effect of gibberellin hormone (GA3) concentration and coconut water on the viability of mangosteen seeds (Garcinia mangostana L.). This research was conducted from July 2023 to September 2023, located in the screenhouse of the Faculty of Agriculture, Sultan Ageng Tirtayasa University. This study used a Factorial Randomized Complete Block Design (RCBD). The first factor is gibberellin hormone (GA3) with 2 levels, G0 (0 ppm) and G1 (75 ppm). The second factor is coconut water with 3 levels, K0 (0%), K1 (25%), and K2 (50%). Parameters observed in this study include the time of shoot emergence, germination capacity, maximum growth potential, normal germination, abnormal germination, non-germinating seeds, and plant height. The research results show that a concentration of 75 ppm gibberellic acid (GA3) has a positive effect on the emergence of shoots and germination capacity. A 50% concentration of coconut water also has a positive effect on the emergence of shoots and germination capacity. There is an interaction between the treatment of 75 ppm gibberellic acid (GA3) and 50% coconut water in the timing of shoot emergence and germination capacity. Keywords: coconut water, giberelin acid, mangosteen seeds INTISARIPenelitian ini bertujuan untuk mengetahui pengaruh konsentrasi hormon giberelin (GA3) dan air kelapa terhadap viabilitas benih manggis (Garcinia mangostana L.).

Hasil penelitian menunjukkan konsentrasi hormon giberelin (GA3) 75 ppm memberikan pengaruh yang baik terhadap waktu muncul tunas dan daya berkecambah. Konsentrasi air kelapa 50% memberikan pengaruh yang baik terhadap waktu muncul tunas dan daya berkecambah. Terdapat interaksi perlakuan antara hormon giberelin (GA3) 75 ppm dan air kelapa 50% pada waktu muncul tunas dan daya berkecambah. Kata Kunci: air kelapa, hormon giberelin, benih manggis

Abstract

The research was aimed to know response of various doses of chicken manure and liquid organic fertilizer from tofu waste on the growth of avocado plant (Persea americana) in seedling phase. This research was conducted from June until August 2023. The method used Randomized Completely Block Design (RCBD) as factorial with two factors. The first factor was the Chicken Manure which consisted of four levels, namely: 0 kg/plant, 0.5 kg/plant, 1 kg/plant and 1.5 kg/plant. The second factor was the Liquid Organic Fertilizer from Tofu Waste, which consisted of four levels, namely: 0 ml/l, 75 ml/, 150 ml/l and 225 ml/l. The results showed that 1 kg/plant dose of chicken manure was the best effect on the number of branches, the number of leaves and diameter of stem. 150 ml/l dose of Liquid Organic Fertilizer from Tofu Waste was the best effect on plant height, the number of branches, the number of leaves and diameter of stem. There was interaction between chicken manure and liquid organic fertilizer  from tofu waste to parameters, plant height, the number of branches, the number of leaves and diameter of stem. Keywords: avocado, chicken manure, liquid organic fertilizer from tofu waste  INTISARI            Penelitian ini bertujuan untuk mengetahui respons pemberian berbagai dosis pupuk kotoran ayam dan POC limbah tahu terhadap pertumbuhan tanaman alpukat (Persea americana) pada fase pembibitan.

Abstract

Sawi pagoda (Brassica narinosa L.) merupakan salah satu jenis sawi yang belum banyak dibudidaya di Indonesia dan produksinya masih terbatas untuk memenuhi kebutuhan sayuran masyarakat. Penggunaan media tanam yang baik dan pemupukan dapat meningkatkan produksi tanaman sawi pagoda. Penelitian ini bertujuan untuk mengetahui pengaruh komposisi media tanam dan dosis pupuk kasgot terhadap pertumbuhan dan hasil tanaman sawi pagoda. Penelitian dilaksanakan di Desa Nambo Ilir, Kecamatan Kibin, Kabupaten Serang, Banten pada bulan November 2024 – Januari 2025. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari dua faktor, yaitu komposisi media tanam (arang sekam, serbuk gergaji, dan cocopeat) dan dosis pupuk kasgot (0 g, 50 g, 100 g, 150 g, dan 200 g). Hasil penelitian menunjukkan komposisi media tanam yang ditambahkan serbuk gergaji memberikan pengaruh terbaik terhadap parameter jumlah daun umur 21 Hari Setelah Tanam (HST) dan 35 HST, berat tanaman, dan berat segar konsumsi. Pemberian pupuk kasgot memberikan pengaruh terbaik dengan dosis 150 g terhadap parameter tinggi tanaman umur 35 HST dan 42 HST. Interaksi terbaik pada kombinasi media yang ditambahkan arang sekam dan pupuk kasgot 150 g terhadap parameter tinggi tanaman umur 21 HST dan 28 HST serta jumlah daun umur 14 HST.

Abstract

Tissue culture is a plant propagation technique using artificial media by adding particular growth regulators (ZPT) to produce plants as expected. Although, the availability of other issues such as browning and contamination can inhibit the process of explant propagation. The addition of cow’s milk to the culture media and BAP is a type of cytokinin is expected to regenerate the growth of banan Kepok Tanjung variety optimally. This study aims to have best concentration of BAP and cow’s milk for the growt Kepok Tanjung explants in vitro. The experimental design used was a randomized with 16 treatment combinations. The result showed a significant of the combination of media treatment of banana Kepok Tanjung variety on the number of leaves (24.2 sheets) and explant height (25.62 cm) starting from 3-12 WAP.
