Abstract

Ubi kayu (Manihot esculenta Crantz) merupakan salah satu komoditas pangan yang memiliki nilai ekonomis.  Produktivitas ubi kayu masih tergolong rendah. Upaya yang dapat dilakukan untuk meningkatkan produksi ubi kayu adalah aplikasi auksin untuk memacu pembentukan akar karena hal yang paling penting dari ubi kayu adalah umbi yang akan di hasilkan.  Tujuan dilakukannya penelitian ini adalah mengetahui pengaruh NAA dan konsentrasi yang terbaik dalam meningkatkan jumlah akar produktif dan pertumbuhan tunas setek singkong. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan perlakuan sebanyak 6 perlakuan yang diulang sebanyak 3 kali.  Perlakuan pada percobaan ini terdiri dari: A0=0 ppm NAA, A1=200 ppm NAA, A2=400 ppm NAA, A3=600 ppm NAA, A4=800 ppm NAA, dan A5=1000 ppm NAA.  Hasil penelitian yang didapatkan adalah NAA berpengaruh terhadap pertumbuhan tunas dan pengakaran setek singkong.  Konsentrasi 200-1000 ppm NAA meningkatkan pengakaran dan pertumbuhan tunas setek singkong, dimana konsentrasi terbaik adalah 1000 ppm NAA menghasilkan jumlah akar total, jumlah akar produktif, panjang akar, dan bobot segar akar tertinggi.

Abstract

Produktivitas cabai merah mengalami penurunan setiap tahunnya hal ini disebabkan oleh kesuburan tanah yang semakin rendah. Upaya yang dapat dilakukan untuk mengatasi permasalahan tersebut yaitu melakukan pemupukan dengan pupuk NPK dan pupuk hayati. Penelitian ini dilaksanakan di Desa Sukabanjar, Gedong Tataan, Pesawaran padai bulan November 2020 sampai April 2021. Metode penelitian yang digunakan yaitu Rancangan Acak Kelompok (RAK) faktorial 4x3 dengan 3 ulangan dan terdapat 12 kombinasi perlakuan. Faktor pertama yaitu perlakuan dosis pupuk NPK 0, 10, 20, dan 30 g/tanaman. Faktor kedua yaitu konsentrasi pupuk hayati Grikulan Plus 0, 15, 30 ml/l. Setiap perlakuan diambil 2 sampel. Homogenitas ragam diuji dengan uji Bartlett dan aditivitas menggunakan uji Tukey, dan uji lanjut dengan BNT padai taraf 5%. Hasil penelitian menunjukkan perlakuan dosis pupuk NPK 30 g/tanaman menghasilkan bobot buah cabai merah paling tinggi yaitu sebesar 521,44 g/tanaman. Pengaplikasian pupuk hayati Grikulan Plus konsentrasi 30 ml/l menghasilkan bobot cabai merah yang lebih tinggi sebesar 415,21 g/tanaman. Interaksi antara dosis pupuk NPK 30 g/tanaman dengan pupuk hayati Grikulan Plus konsentras 30 ml/l menghasilkan bobot cabai merah yang tertinggi yaitu sebesar 657,67g/tanaman atau setara dengan 13,15 ton/ha.

Abstract

Pineapple (Ananas comosus [L.] Merr.) is one type of fruit that has an important role in Indonesia because it is a major export commodity, both in fresh and processed forms such as canned fruit and juice. Therefore, the development of pineapple production is a strategic matter. One of the steps taken to increase pineapple production is through proper and balanced fertilization. The objective of this study was to determine the best fertilizer package that supports the growth of pineapple plants. The research was conducted from November 2022 to March 2023 using a single-factor Randomized Group Design (RAK), consisting of treatments and repeated 4 times.  The treatment packages tested included the dose and interval of fertilization, namely: P0= 200 kg DAP + 200 kg Kiesirite + 300 kg K2SO4 + 50 kg ZA per ha (0, 30 HST), P1= 300 kg DAP + 300 kg Kiesirite + 300 kg K2SO4 + 50 kg ZA per ha (0, 30, 60 HST), P2= 300 kg DAP + 300 kg Kiesirite + 300 kg K2SO4+ 50 kg ZA per ha (0, 15, 45 HST), P3= 350 kg DAP + 350 kg Kiesirite + 350 kg K2SO4 + 50 kg ZA per ha (0, 30, 60 HST), and P4= 350 kg DAP + 350 kg Kiesirite + 350 kg K2SO4 + 100 kg ZA per ha (0, 15, 45 HST). In each experimental unit, 5 sample plants were selected, so that the total plants observed were 100 sample plants. The data were analyzed using analysis of variance, and the F test showed significant differences which were then further tested with the Least Significant Difference (BNT) test at the 5% level.  The results showed that in general, fertilizer doses and intervals had no significant effect on most of the observed variables, except on d-leaf width and d-leaf length.  The fertilizer package in the P0 treatment (200 kg DAP + 200 kg Kiesirite + 300 kg K2SO4 + 50 kg ZA) per ha proved to be the best to support pineapple plant growth. Keywords: dosage, fertilization frequency, pineapple, inorganic fertilizer

Abstract

The growth and production of cassava can be increased through various efforts, including the use of superior varieties, fertilization, the addition of organic materials, and the application of growth regulators (PGR). Naphthaleneacetic acid (NAA) and indole-3-butyric acid (IBA) are PGRs that have been widely documented to stimulate root initiation and development in cuttings. The application of aauxin mixtures on cassava cuttings followed by fertilization and the addition of organic materials is expected to improve the growth and yield of cassava. The aim of this experiment is to study the effects of the application of an NAA and IBA mixture (1:1) and the type of fertilizer on the growth and yield of the Garuda variety of cassava. This research is designed using a clustered randomized block method with three replications. The design used is factorial 2x3, consisting of two main treatment factors. The first factor is the combination of growth regulators NAA and IBA in a 1:1 ratio at three concentration levels, namely 0 ppm, 500 ppm, and 1,000 ppm. The second factor includes the type of fertilizer used, which is a single inorganic fertilizer and a combination of inorganic fertilizer with cow manure. Each experimental unit in this study consists of 10 cassava cuttings planted in an orderly manner with a planting distance of 1 meter x 1 meter between plants. The results of the experiment showed that the application of inorganic fertilizer produced plant growth and the number of productive roots equivalent to the use of inorganic fertilizer + cow manure. The application of a mixture of auxins NAA and IBA (1:1) at concentrations of 500 ppm and 1,000 ppm significantly increased the growth of shoots, the number and weight of productive roots of the Garuda variety cassava, but both treatments resulted in cassava growth and yield that were not different. Key words: Cassava, cow manure, growth, IBA, NAA, yield

Abstract

Shallot is one of important horticultural crops in Indonesia; shallot consumption per capita is estimated to be 4.6 kg per year. The objective of this study was to evaluate the effect of combining biofertilizer and organic fertilizer on the production of shallot in Sukabanjar village, Pesawaran, Lampung, Indonesia. The study was set up using a randomized completely block design with two factors, biofertilizers and various organic fertilizers, i.e. cow manure, chicken manure, rice straw compost, oyster mushroom baglog. Our study demonstrated that combining biofertilizer and organic fertilizer significantly increased the number, diameter, and fresh and dry weight of tubers of “Bima Brebes” shallot. Shallots treated with biofertilizer combined with oyster mushroom baglog produced the highest tuber yield of 1788 g compared to 282 g in the control.

Abstract

A preliminary study of the reproductive responses of crystal guava plants under varying doses of paclobutrazol and NPK fertilizer was conducted. The research took place in a small-scale ‘Crystal’ orchard in Rajabasa 1, East Lampung, from August 2021 to March 2022. The study employed a 3x3 factorial randomized complete block design, examining two factors: paclobutrazol and NPK fertilizer. The first factor, paclobutrazol (P), had three levels: 0 ppm (control), 2000 ppm, and 4000 ppm. The second factor, NPK fertilizer, was tested at three levels: 0 g per plant (control), 250 g per plant, and 500 g per plant. The key variables measured were the number of reproductive shoots, blooming flowers, and fruits, serving as indicators of the ‘Crystal’ guava plant's reproductive responses. The study findings recommended the application of 2000 ppm paclobutrazol and 500 g per plant of NPK fertilizer due to their significantly positive impact on increasing the number of reproductive shoots, blooming flowers, and fruits. Notably, there was no significant interaction observed between paclobutrazol and NPK treatments in regulating plant reproductive growth.
