Abstract

Cabai rawit (Capsicum frutescens L.) memiliki peran penting dalam menu masakan di Indonesia. Pengelolaan tanaman secara konvensional dengan pemupukan yang kurang efisien masih banyak dilakukan oleh petani, sebaliknya pemupukan secara fertigasi meningkatkan hasil dapat dan menurunkan biaya produksi. Penelitian ini bertujuan untuk mengetahui metode aplikasi pemupukan melalui irigasi dan sumber N yang dapat menigkatkan hasil cabai rawit dengan budidaya memakai mulsa plastik. Penelitian ini dilakukan pada jenis tanah Inceptisol (Dytropept Fluventik, Isohiperthermik). Perobaan dilakukan di Kebun Penelitian Institut Pertanian Bogor, Cikarawang. Percobaan pertama pada Juni-Desember 2016 disusun dalam rancangan acak kelompok (RAK), 4 ulangan dengan 3 metode aplikasi fertigasi: split, irigasi tetes, dan konvensional(tanpa fertigasi). Percobaan kedua dilakukan pada Maret-Oktober 2017 disusun dalam RAK dengan empat ulangan dengan perlakuan tiga sumber N (Urea (46% N), ZA (21% N), dan NPK (16-16-16)% N-P2O5, -K2O). Hasil penelitian menunjukkan bahwa split dan drip tidak memberikan pengaruh yang berbeda terhadap total panen dan hasil panen yang dapat dipasarkan, namun keduanya lebih tinggi dari hasil panen dengan konvensional. Hasil percobaan kedua menunjukkan bahwa semua sumber N tidak berpengaruh terhadap pertumbuhan dan hasil panen cabai. Kata kunci: irigasi mikro, nitrogen, mulsa plastik, pemupukan

Abstract

Beneng taro is a perennial of Araceae and becomes a new commodity in Indonesia. The research aimed to evaluate the growth and yield of beneng taro on various statuses of soil organic carbon (SOC). Three genotypes of taro, i.e., beneng Banten, beneng Bondowoso, and East Nusa Tenggara (NTT) fodder taro were planted in three SOC levels, i.e., 1.79, 2.94, and 4.09% in a randomized split block design in the Leuwikopo Experimental Station, IPB from April to December 2021. SOC was designed by adding cow manure. The results showed that there was no interaction between genotypes and SOC. The increase in SOC from 1.79 to 4.09% did not significantly affect growth but significantly affected the diameter and yield of beneng and NTT fodder taro. An increase in SOC above 1.79% markedly decreased tuber diameter, but conversely increased fresh tuber weight. Tuber weight increased by 5.6% and 12.1% with an increase in SOC from control to 2.94% and 4.09%, respectively. The increase in tuber weight was supported by the trend of increasing biomass weight and the number of roots. SOC source in the present study was cow manure which may also contribute some nutrients, therefore, further research is needed using neutral organic carbon sources to determine the effect solely.

Abstract

Tidal areas are believed as future land for many commodities in Indonesia. Here, shallot growing was evaluated on tidal land supplemented with soil conditioners. The research aimed to evaluate the adaptive response of shallot varieties for growing on tidal land with a water-saturated system indicating Fe and Al stress by applying soil ameliorant and actinobacterial. The study used a completely randomized factorial design with three replications. The first factor was shallot variety (Bima Brebes, Batu Ijo, and SS Sakato) and the second factor was soil conditioners (no ameliorant, actinobacteria, ameliorant+actinobacteria, and actinobacteria+ameliorant+dolomite). Bima Brebes and Batu Ijo cultivars had the highest growth percentage, age at shoot emergence, plant height, and number of leaves, while the SS Sakato variety had the slowest growth. Shallot production variable had a significant interaction with soil conditioners. Bima Brebes variety demonstrated high suitability for a water-saturated system in tidal land, and actinobacteria+ameliorant+dolomite was a more promising conditioner than other treatments. Keywords: pyrite, saturated soil culture, tidal swamps, growth, yield, marginal land.

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

Agronomic practices in Indonesia mostly still use ammonium as the primary source of nitrogen (N), whereas ammonium concentrations at certain levels can cause plant toxicity. The selection of the suitable N form (NH4+ and NO3-), especially by the fertigation method, is expected to increase the efficiency of N fertilization. This research aimed to obtain the appropriate source of NH4+ and NO3- to increase production and efficiency of fertilization in shallots. The experiment used a non-factorial randomized complete block design with four replications and six nitrogen treatments: without N, ammonium sources (urea, ZA), nitrate source (calcium nitrate), and combination of ammonium and nitrate (NPK Mutiara 16-16-16, calcium ammonium nitrate). The fertilizer doses contain N in equivalent levels, i.e., 167.9 kg N ha-1. The results showed that ZA increased the chlorophyll content of leaves and N content of plant tissue, while calcium nitrate increased the size and weight (fresh and dry) of bulb per plant. The highest recovery and agronomy efficiency was obtained in the ZA application, while the highest physiological efficiency and partial factor productivity were in calcium nitrate. Therefore, nitrate has the potential for shallot cultivation because it can increase production without accumulation in the bulbs.

Abstract

Penetapan rekomendasi dosis kalium (K) berdasarkan uji tanah untuk tanaman tomat pada tanah Andisol belum banyak dikaji di Indonesia. Penelitian ini bertujuan untuk menentukan rekomendasi pemupukan kalium (K) pada tanaman tomat di tanah Andisol berdasarkan uji tanah. Tahapan penelitian meliputi penetapan status hara K tanah, uji korelasi K di rumah kaca, uji kalibrasi K di lapangan, serta penentuan rekomendasi pemupukan K. Penetapan status hara K tanah dilakukan dengan enam tingkat ketersediaan K dari sangat rendah hingga sangat tinggi (0, ¼X, ½X, ¾X, dan X), di mana X merupakan nilai tertinggi serapan hara K tanah sebesar 413.4 kg K ha-1. Penelitian ini menggunakan pendekatan lokasi tunggal dengan rancangan acak kelompok sebanyak lima ulangan. Hara K diinkubasi selama empat bulan, kemudian dilakukan pengambilan sampel tanah untuk analisis kandungan K. Uji korelasi dilakukan di rumah kaca dengan rancangan acak lengkap lima ulangan, sedangkan uji kalibrasi di lapangan menggunakan rancangan petak terbagi dengan rancangan acak kelompok lima ulangan. Hasil penelitian menunjukkan bahwa metode ekstraksi K terbaik untuk tanah Andisol pada tanaman tomat adalah NH₄OAc. Batas ketersediaan hara K-NH₄OAc ditetapkan sebagai sangat rendah (<84 ppm K), rendah (84–<121 ppm K), sedang (121–<202 ppm K), serta tinggi dan sangat tinggi (>202 ppm K). Kebutuhan K untuk hasil maksimum tomat pada tingkat kesuburan sangat rendah, rendah, dan sedang berturut-turut adalah 442, 363, dan 298 kg K₂O ha-1, sedangkan untuk hasil optimum berturut-turut sebesar 426, 348, dan 283 kg K₂O ha-1.  Kata kunci: hara K, NH4OAc, uji kalibrasi, uji korelasi

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.
