Abstract

Upland Soil Test Kit (PUTK) is a rapid soil analysis kit that estimates the nutrient availability in soil. From previous studies, tomato plant production showed a good correlation with available phosphorus (P) and potassium (K) analysis using the PUTK. This study aimed to find the optimal P fertilizer rate based on PUTK analysis for tomato fertigation. This experiment was carried out using a randomized complete block design, four replications with a single factor, namely P fertilizer rate comprising 0% X, 50% X, 100% X, 150% X, and 200% X, with X the recommended P fertilizer of PUTK on moderate P availability (175 kg ha­1). The ANOVA showed that P fertilizer did not significantly affect the vegetative growth, production, and fruit quality of tomatoes. It means that PUTK analysis had low accuracy as a basis for determining the optimum P fertilizer rate for tomato fertigation. The low accuracy could be due to PUTK underestimating the status of soil P availability. Mechlich-1 analysis showed that the experimental field had high P availability (44.6 ppm), while PUTK analysis still indicates moderate P availability. This shows that PUTK needs to be developed further, especially quantifying the result to help make informed and accurate decisions.

Abstract

Kegiatan penelitian dilaksanakan pada bulan Maret–Juli 2021 di Bogor, Jawa Barat. Penelitian bertujuan untuk meningkatkan kemampuan dalam pengelolaan tanaman hias khususnya peperomia, bromelia, begonia, dan hortensia. Kegiatan pengelolaan tanaman hias mencakup jadwal produksi mulai dari persiapan tanam hingga siap panen dan kriteria panen tanaman. Pengamatan tanaman Peperomia obtusifolia, Neoregelia schultesiana, dan Hydrangea macrophylla meliputi jumlah daun dan tinggi tanaman. Pengukuran tanaman Peperomia argyreia dan Peperomia caperata meliputi jumlah tunas. Pengukuran Begonia ‘orococo’ meliputi panjang daun, lebar daun, dan jumlah daun. Kegiatan budidaya tanaman hias yang dilakukan meliputi persiapan media tanam, pembibitan, penyiraman, pemupukan, pengendalian hama penyakit, panen, dan pascapanen. Hasil pengamatan pada tanaman Peperomia obtusifolia, Neoregelia schultesiana, dan Begonia ‘orococo’ yang menggunakan metode perbanyakan stek batang tergolong cepat, sedangkan Peperomia caperata dan Peperomia argyreia yang diperbanyak dengan menggunakan metode stek daun memiliki pertumbuhan yang lambat sehingga selama penelitian tanaman tidak memenuhi kriteria pemasaran. Hydrangea macrophylla memiliki umur panen rata-rata sekitar 15 MST. Kemampuan teknis mahasiswa meningkat dalam pengelolaan tanaman hias. Hasil analisis usahatani dengan asumsi luasan 200 m2 pada Peperomia obtusifolia, Peperomia argyreia, Peperomia caperata, Begonia ‘orococo’, dan Neoregelia schultesiana menunjukkan hasil R/C rasio >1 yang berarti menguntungkan. Kata kunci: analisis usaha tani, kriteria panen, pembibitan tanaman hias, stek daun, stek batang

Abstract

Cayenne pepper (Capsicum frutescens) is one of the important horticultural commodities in Indonesia. According to Central Statistics Agency data, annual consumption has been rising amid fluctuating production, including a 37.68-thousand-ton decline in 2023 compared with 2022. Cayenne pepper requires a specific nutrient profile to achieve optimal yields. Micronutrients, including boron, copper, iron, manganese, molybdenum, and zinc, are vital for photosynthesis, flower development, and nutrient uptake; deficiencies impair growth, fruit quality, and disease resistance, underscoring the need for balanced fertilization. Micronutrient deficiencies can reduce plant growth, fruit quality, and disease susceptibility. Research on micronutrient provision in cayenne pepper plants remains limited. This research aims to determine the most effective method of nutrient application for cayenne pepper plants. The design used was a single-factor randomized group design. The results of the study demonstrate that micronutrient applications can increase the height and diameter of cayenne pepper stems, with foliar spray applications yielding the best response in terms of vegetative parameters. However, micro-nutrient application has not significantly affected the yield and yield components of cayenne pepper.
