Abstract

Di Indonesia, tren penggunaan pohon buah sebagai tanaman penghijauan di perkotaan terus meningkat. Di sisi lain, karakterisasi agro-ekologi pohon buah sebagai tanaman penghijauan di perkotaan masih belum teridentifikasi dengan baik, termasuk faktor pembatas yang mempengaruhi pertumbuhan tanaman. Penelitian bertujuan untuk mengidentifikasi karakteristik agro-ekologi dan keragaman pohon buah sebagai tanaman penghijauan di pinggir jalan. Pemilihan objek pengamatan dalam penelitian ini adalah keragaman tanaman penghijauan yang ada di pinggir jalan Kota Bandung dengan metode transek mengikuti jalur jalan kendaraan. Secara umum, ditemukan 23 spesies tanaman penghijauan di pinggir jalan dengan 14 tanaman adalah pohon buah. Indeks keragaman Shannon-Wiener’s (H’) tanaman penghijauan pinggir jalan yakni 1.29-1.94 termasuk keragaman sedang. Indeks dominansi Simpson (C) berkisar antara 0.18-0.48, menunjukkan tidak ada jenis tanaman yang mendominasi pada setiap segmen jalan. Pohon kersen dapat ditemukan pada seluruh tipe jalan yang diamati, mengindikasikan pohon buah ini secara sengaja ditanam sebagai tanaman penghijauan pinggir jalan. Kajian lanjut pada 14 pohon buah di 11 ruas jalan menunjukkan faktor pembatas utama yang dihadapi adalah bawah pohon sebagai tempat usaha, kabel melintang di atas pohon, dan lokasi akar sempit. Asesmen risiko pohon buah secara keseluruhan tidak ditemukan tingkat risiko tinggi. Berdasarkan hasil tersebut dapat diambil kesimpulan bahwa pohon buah yang teridentifikasi laik dipertimbangkan sebagai tanaman penghijauan pinggir jalan dengan kajian lanjut berkaitan dengan karakteristik morfologi dan kesesuaian fungsi tanaman.

Abstract

Aplikasi paclobutrazol pada tanaman padi untuk mengurangi tinggi batang merupakan strategi adaptasi terhadap perubahan iklim yakni agar tanaman lebih tahan rebah. Namun demikian, pengaruh aplikasi paclobutrazol terhadap kualitas beras masih jarang diteliti. Penelitian bertujuan untuk mengkaji kualitas mutu beras dari empat varietas tanaman padi yang diberi perlakuan paclobutrazol. Penelitian dilaksanakan pada bulan Februari-Juli 2021 di Kebun Percobaan Sawah Baru IPB, Bogor. Empat varietas yakni IPB 3S, Inpari 42, Hipa 18, dan Tarabas diperlakukan dengan paclobutrazol (K1 = 0 ppm, K2= 150 ppm, K3 = 300 ppm, K4 = 450 ppm, K5 = 600 ppm), yang diaplikasikan melalui daun saat tanaman bunting sebelum malai muncul. Hasil penelitian menunjukkan bahwa perlakukan paclobutrazol memengaruhi mutu beras khususnya persentase beras pecah kulit, beras giling dan beras kepala, bentuk beras, serta kandungan amilosa. Varietas padi memberikan respon berbeda terhadap perlakuan paclobutrazol. Konsentrasi 150 ppm mulai memengaruhi mutu beras yakni meningkatkan beras pecah kulit pada semua varietas, beras giling pada IPB 3S dan Inpari 42, dan beras kepala serta kandungan amilosa pada IPB 3S dan Hipa 18; tetapi menurunkan beras kepala pada varietas Tarabas dan kandungan amilosa pada Inpari 42. Perlu penelitian lebih lanjut residu paclobutrazol pada beras untuk memastikan keamanan pangan. Kata kunci: beras giling, beras kepala, cuaca ekstrim, perubahan iklim, varietas padi

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

Moringa is drought tolerant and its leaf is traditionally used as a vegetable. Recently, the leaf is used commercially in traditional medicine and functional foods. Fulvic acid is a kind of plant growth regulator derived from humic acid and is considered a fertilizer in sustainable agriculture. The objective of the research was to determine the effect of fulvic acid concentration on the growth, biomass, phosphorus and flavonoids contents of moringa seedlings. The experiment was conducted from July 2020 to January 2021 at Leuwikopo Experimental Station, Bogor. The treatment was arranged in a randomized block design consisting of two factors, i.e., fulvic acid level (0, 1, 2, 3, and 4 mL L-1) and moringa accessions (East Nusa Tenggara-ENT and Leuwikopo-LWK). Observation focused on growth and biomass, total flavonoids, and phosphorus contents of leaves. The results showed that fulvic acid enhanced leaf growth, and plant height. On the other hand, the fulvic acid application had no significant effect on biomass production, total flavonoids, and phosphorus contents of moringa leaves. Accessions expressed different responses to fulvic acid levels, i.e.e, the fulvic acid of 1 mL L-1 seemed favorable for ENT accession while 2 mL L-1 was favorable for LWK accession as indicated by the level of flavonoid content. Therefore, fulvic acid is beneficial in moringa cultivation, particularly for ENT accession. It is interesting to evaluate the fulvic acid application on moringa trees grown in ENT where soil moisture is considered low.

Abstract

Climate change, i.e., changing rainfall refers to drought and excess rainfall, is known to affect the growth and yield of tea production in many regions. However, research on the impact of climate change on tea plantations in Indonesia is still limited. The study aimed to evaluate the impact of changing rainfall on the productivity of tea plantation at Cianjur, West Java. The data was collected from interviews, field data, and company records from April to July 2022. The results showed that changing rainfall of both limited rainfalls during El Nino and excess rainfall during La Nina affected the tea production. Annual tea productivity declined during both climatic events. Shortage of water during El Nino primarily reduced crop growth, while excess rainfall during La Nina reduced the capacity of tea pickers and increased labor for crop maintenance. Failure to adapt to the direct and indirect impacts of climate change could contribute to declining tea production in Indonesia. Thus, comprehensive action is needed including capacity building in human resources, water management, and microclimate adaptation such as shading plants and tolerant clones to sustain tea production under climate change events.

Abstract

The demand for cassava tuber in Indonesia is high, however, domestic production is still limited therefore increasing production is important. Ultisol soils have the potential for cassava production, but low soil fertility in such soils needs to be improved. The research aimed to evaluate the effect of soil organic carbon (SOC) and NPK fertilizer on the growth and yield of cassava tuber in an ultisol. The experiment was conducted at the Jonggol Experimental Farm, IPB Bogor, West Java from September 2022 to January 2023. The experiment used a split-plot design with three replications. The main plot was SOC level of 1.93 (control), 2, 3, and 4%, and the subplot was NPK 15-15-15 level of 150, 300, 450, and 600 kg ha-1. SOC level was increased through the application of cow manure 0, 3.59, 54.93, and 106.27 tons ha-1 corresponding to SOC levels of 1.93 (control), 2, 3, and 4%, respectively. Results showed that enhancing SOC up to 3% and NPK 300 kg ha-1 were enough to support cassava growth as shown by plant height, stem diameter, and leaf number. The leaf number was the highest in the 3% SOC+150 kg NPK, 2% SOC+300 kg NPK or+450 kg NPK, and control+600 kg ha-1 NPK treatment. Leaf greenness was only affected by adding NPK fertilizer; a high greenness value was obtained at NPK level of > 150 kg ha-1 and 300 to 600 kg ha-1 resulting in non-significantly leaf greenness. The status of N and K in the leaves increased by SOC and NPK treatments, while the P status was unaffected. SOC at a level of 3% and NPK at a level of 150 kg ha-1 stimulated cassava to produce the highest fresh tuber weight (1.85 kg per plant) at 4 months after planting. Cassava productivity in ultisol soil can be increased by applying cow manure of 54.93 tons ha-1 to enhance SOC up to 3% combined with NPK of 150 kg ha-1.

Abstract

Javanese konjac or iles-iles (Amorphophallus muelleri Blume, Araceae) is a tuber crop native to Indonesia as a source of carbohydrat, also contains a lot of glucomannan, which has high economic value as a raw material in industry. The study aimed to develop the propagation method of A. muelleri from bulbils and leaf cuttings through the plant growth regulator (PGR) application of α-naphthaleneacetic acid (NAA) and benziladenin (BA). The research was conducted from August 2020 to December 2021 at IPB University, Bogor. The study consisted of three experiments based on the type of propagation material. Each experiment used a randomized complete block design with three factors, i.e., NAA concentrations (0, 2, and 4 mg L-1), BA concentrations (0, 5, 10, and 15 mg L-1), and propagation materials (Experiment 1: small, medium, large bulbils; Experiment 2: immature and mature peak leaflet cuttings; Experiment 3: immature and mature base leaflet cuttings). The results showed that there was an interaction of three factors in the bulbils and PGR application, which had a significant effect on the percentage of axillary shoot proliferation and growth. In Experiment 2, PGR application was unable to regenerate peak leaflet cuttings, whereas in Experiment 3 PGR encouraged base leaflet cuttings to form shoots, roots, and bulbils, especially at concentrations of 2 mg L-1 NAA+15 mg L-1 BA and 4 mg L-1 NAA+15 mg L-1 BA. Keywords: α-naphthaleneacetic acid, benziladenin, iles-iles, Javanese konjac, plant growth regulators

Abstract

Amorphophallus muelleri Blume locally called Iles-iles or porang becomes a new commercial commodity in Indonesia. The tuber as the most economic value contains high glucomannan. It has been speculated that the high variation in production among farmers is due to different planting materials and soil organic carbon (SOC). Thus, the research aimed to evaluate the growth and yield of A. muelleri from different planting materials and levels of SOC. The research was carried out at Leuwikopo Experimental Station IPB Bogor from December 2021 to August 2022, using a nested design. The main plot was the level of SOC (2%, 3%, 4%, 6%), and the sub-plot was planting materials (seeds, bulbils, and tubers from leaf cuttings). The results showed SOC status determined growth and yield. Plant height, stem diameter, number of leaves, canopy width, leaf greenness, number of tubers, weight, and size of tubers, stomatal conductance, and intercellular CO2 were significantly affected by SOC level. SOC at a level of 6% stimulated the highest growth and yield. Planting materials also determined the growth and yield. Plants originating from bulbils produced the highest yields, followed by tuber from leaf cuttings, and seeds. It is recommended to plant bulbils accompanied by maintaining SOC at a level of 6%.

Abstract

Maize and peanuts are important food crops in Indonesia and are generally planted in monoculture and intercropping systems. The water required for monoculture and intercropping is believed to be different. However, comparison analysis of water requirements in monoculture and intercropping is rarely conducted. The research aimed to evaluate the growth and production of sweet corn and peanuts in monoculture and intercropping systems concerning water requirement and crop coefficient. The study was conducted at IPB Experimental Station in Leuwikopo, Bogor, Indonesia from September to December 2022. Sweet corn and peanuts were planted in different cropping systems, i.e., monoculture and intercropping. Water consumption of both cropping systems was evaluated in every growing stage. The experiment used a completely randomized block design and was repeated three times. Results showed that sweet corn growth was not significantly different among cropping systems, but yield from intercropping was lower than monoculture. Intercropped peanuts grew lower than monoculture but did not show any significant difference in yield among cropping systems. Water use efficiency in intercropping was higher than monoculture for both crops, indicating intercropping is a suitable cropping system for limiting soil water availability. The land equivalency ratio was 1.80, concluding that intercropping was more efficient than monoculture in land use by 80%. Keywords: climate change; crop coefficient; intercropping; land equivalent ratio; water use efficiency
