Abstract

Peningkatan pertumbuhan dan hasil tanaman mentimun dapat dilakukan melalui pemupukan menggunakan pupuk guano karena dapat memperbaiki kesuburan tanah. Selain pemupukan, diperlukan perlakuan pemangkasan pucuk yang berguna untuk mengatasi adanya pertumbuhan vegetatif yang berlebihan pada tanaman. Tujuan dari penelitian ini adalah mengetahui pengaruh kombinasi dosis pupuk guano dan waktu pemangkasan pucuk yang mana terbaik untuk pertumbuhan dan hasil tanaman mentimun. Penelitian ini dilaksanakan pada bulan Desember 2022 - Maret 2023 di Kelurahan Gadang, Kecamatan Sukun, Kota Malang, Jawa Timur. Penelitian ini menggunakan percobaan faktorial yang disusun berdasarkan Rancangan Acak Lengkap (RAL) dengan 2 faktor perlakuan. Faktor pertama yaitu Pemangkasan (0; 10; 13; dan 16 HST). Faktor kedua yaitu dosis Pupuk Guano (0; 75; 125; dan 175 g). Hasil penelitian menunjukkan kombinasi perlakuan waktu pemangkasan pucuk 13 HST dan dosis pupuk guano 175 g/tanaman memberikan pengaruh nyata pada parameter tinggi tanaman, jumlah bunga betina, dan bobot buah per tanaman.

Abstract

Background: The success of water guava plant propagation is determined by proper cultivation and the availability of superior seeds. Water guava seedlings can be produced through generative and vegetative propagation or a combination. Splicing is joining two different parts of a plant into a whole unit and growing as one plant after tissue regeneration occurs in the graft scar. This study aims to determine the effect of the planting media type, the correct NPK fertilizer dose, and the interaction between the two on the growth of water guava seedlings resulting from shoot grafting. Methods: This research was conducted at the Horticultural Seed Development Unit, Pasuruan, East Java. This research took place from April to June 2023. Consisting of 2 factors, namely the composition of the soil planting media, soil: cow dung, soil: cow dung: rice husk charcoal, and the dose of NPK fertilizer, namely 16-16-16 1.3 grams, 2.7 grams, 4 grams. with two factors carried out, 1) the composition of the planting media (M) consisting of 3 levels and 2) the dose of NPK fertilizer 16-16-16 (D) consisting of 3 levels of treatment. The parameters observed were the time of emergence, number of shoots, length of shoots, number of leaves, height of grafted plants, and percentage of finished grafts. Results: The results showed that the treatment of the best results with the interaction of the composition of planting media soil: cow manure: husk charcoal with a dose of NPK fertilizer four g/plant at the age of 86 hssp on the shoot length parameter (5.86 cm). Single treatment, namely the composition of soil planting media: cow dung showed the best results in the parameter of the number of leaves 43 hssp (9,59), 57 hssp (13,22 strands), 73 hssp (21,30 strands) and 86 hssp (28,11 strands) and the percentage of finished grafts (87.80%), and the dose of NPK fertilizer 2,3 g/plant showed the best results in the parameter of shoot emergence time (9,96 hssp) and the dose of NPK fertilizer four g/plant on the shoot length parameter at the age of 43 hssp (0,83 cm). Conclusions: Using the composition of planting media and the dose of NPK fertilizer 16:16:16 can increase the yield of shoot grafts of water guava plants.

Abstract

Cavendish banana (Musa acuminata L.) propagation through conventional methods requires a considerable amount of time. Tissue culture techniques offer a more efficient alternative, enabling the production of plantlets with superior quality and quantity in a shorter period. The application of Zn nanoparticles has been shown to reduce media contamination and act as a biostimulant, enhancing propagation efficiency in tissue culture. Auxins, such as Naphthalene Acetic Acid (NAA), facilitate cell development and root induction, while cytokinins, including 6-Benzyl Amino Purine (BAP), are effective in stimulating cell division, morphogenesis, and shoot formation with improved stability and resistance to oxidation. This study was conducted from February to June 2023 at the Biotechnology Laboratory, Faculty of Agriculture, Universitas Pembangunan Nasional "Veteran" Jawa Timur. The research utilized a Completely Randomized Design (CRD) with two factors: the concentration of Zn nanoparticles and the ratio of ZPT concentrations. The results indicated that the best treatment for multiplication was obtained with 50 ppm Zn nanoparticles, resulting in the fastest shoot emergence at 24,63 days and the highest number of shoots per plantlet at 2,58 shoots. Furthermore, the treatment with a ZPT concentration ratio of NAA + BAP (0:0) produced the highest average number of plantlet leaves, with 5,78 leaves per plantlet.
