Abstract

Title : The Effect of Maturity Level of Empty Fruit Bunch Compost and Mulch from Palm Oil Waste to Tomato Productivity in Ultisol. This research was conducted to understand the effect of maturity level of empty fruit bunch compost and mulch from palm oil waste to tomato productivity in ultisol soil. This research used split plot design with mulch as main plot and maturity level of compost as sub plot. The mulch consists of four types: control, shell, fiber, and chopped of empty fruit bunch. The maturity level of compost consists of 5 levels: control, 4 weeks, 6 weeks, 8 weeks, and 10 weeks. Material used in this research was tomato Ratna variety. Compost of 8 weeks gave the lowest value of C/N ratio (35.16) than 4, 6, and 10 weeks. This compost also had the highest level of N-total, P and Mg: 1.34 %, 0.08 %, and 0.25 %. Compost containing the lowest C/N ratio and higher nutrition gave better vegetative growt. Compost of 8 weeks and fiber mulch provided the highest harvest weight and the highest number of fruit (436.56 gram and 16 fruits). Fruit number and fruit weight were lower than general tomato cultivation because of soil condition. Soil type was ultisol which had lower acidity level. The lower KTK level of this soil made distruption in nutrients uptake. Compost of 8 weeks could increase harvest weight 52.59 % higher than control and also could raise number of fruit 82.53 % higher than control. Shell mulch presented negative effect to growth and productivity of tomato.

Abstract

Extreme weather incidents refer to high rainfall and strong winds have been speculated to be detrimental on rice production. However, researches on the local adaptation to their impact on rice production are limited especially on tropical region like Indonesia. A study was conducted in Pesawaran, West Lampung, North Lampung, and Bandar Lampung using time series data of 2000-2015 and ground checking during extreme weather and normal seasons and its implication on sustainable management. Data were evaluated using multivariate regressions. Results demonstrated that the impact of extreme weather on the reduction of rice production was weak, 0.92%. Shifting on rice production among swampy, irrigated, and dry lands at which covered area of 13.67%, 42.69% and 43.65%, respectively, minimized the impact of the extreme weather. During limited precipitation, irrigated and swamplands had 2.5-3.0 times cropping intensity. Conversely, during La-Nina with excess precipitation, cropping in irrigated and drylands increased by 20 and 58%, respectively. Moreover, the local government maintained annual production improvement by about 5% through expansion of irrigated land, high yielding varieties and inputs subsidies. Considering that incident of extreme weathers tended to occur more frequently, consequently, planting calender utilization and rice variety adapted should be implemented.

Abstract

Plant spacing arrangement might benefit hill strength from the impact of strong wind velocity during extreme weather situations. Here, a loading test to evaluate rice hill strength was performed on Ciherang variety grown in square and double row spacing 2:1. The research was conducted at Cilubang village, Dramaga, Bogor, West Java, Indonesia from March to May 2017. Weight holding capacity was evaluated in 85 days after transplanting on four levels of hill height, i.e., 80 cm, 60 cm, 40 cm, and 20 cm above soil level with three-time replication. The results showed that double-spaced hills had 66.0 % ± 3.1 % stronger than those of square spacing at all height measurement. To lodge a hill into 20 cm to 40 cm from soil level, it required 346.7 g to 741.7 g in square spacing, and 555.2 g to 1149.2 g in double row spacing. Stronger hills in double row spacing seemed to correlate with a higher number of tiller and hills architecture; it requires further study in the role of both factors on the hill strength improvement. The present study recommends applying double row spacing to improve rice hill strength especially at a time with a high chance of lodging by strong wind incident.

Abstract

To mitigate the impact of extreme weather incidents, rice cultivars Way Seputih (WS) and Way Apo Buru (WAB) were evaluated under simulation of continuous wind and rainfall treatments. The research was conducted from July to October 2017 at Leuwikopo Experimental Farm, Bogor, Indonesia. For 15 days at day time, flowering rice hills were treated with about 100 mm/h water shower (Experiment-1), and with 0, 10-15, 20-25 and 35-40 km/h wind velocity (Experiment-2). Results showed that wind and rainfall treatments reduced rice production; the effect depended on the genotypes and flowering stage. Rain treatment from panicle emergence to 50%-emerged increased the number of unfilled grains by 154.6-182.3% and 55.7-101.9% in WS and WAB cultivars, respectively. Rain treatment at 100%-emerged had no effect on WS, but it increased unfilled grain (163.5%) and decreased grain index (12.9%) in the WAB cultivar. Wind speed at 35-40 km/h promoted a high percentage of grain drop (25.7%) and unfilled grains (77.3%), and low grain index (20.8 g) in WS genotype. WAB was more tolerant of wind stress than the WS. The present experiment showed that genotype had different responses to wind and rain treatments implying different mitigation strategies should be applied through genotype selection.

Abstract

Ubi kayu atau singkong merupakan komoditas industri dan komponen penting pada ketahanan pangan di Indonesia, tetapi informasi jejak karbon dari kegiatan budidaya masih terbatas. Jejak karbon adalah salah satu pendekatan untuk memahami sumber emisi gas rumah kaca (GRK) yang berguna untuk mitigasi pemanasan global. Penelitian bertujuan melakukan asesmen jejak karbon budidaya ubi kayu pada berbagai taraf pupuk NPK dan karbon organik tanah (C-org). Penelitian dilakukan pada September 2022 hingga Mei 2023 di Kebun Percobaan IPB Jonggol. Data emisi diestimasi menggunakan skenario tier 1. Budidaya ubi kayu memiliki jejak karbon 2,511.2-10,641.4 kg CO2-eq ha-1 tergantung dosis NPK dan C-org. Budidaya mengemisikan karbon rata-rata 6,455.5 kg CO2-eq ha-1 dengan emisi langsung 4,532.3 kg CO2-eq ha-1dan tidak langsung sebesar 1,923.2 kg CO2-eq ha-1. Input NPK dan pupuk kandang menyumbang emisi langsung terbesar yakni berturut-turut 36.99% dan 54.96%. Pada waktu yang bersamaan, budidaya menskuestrasi karbon 27,445.1- 61,684.2 kg CO2-eq ha-1 (rata-rata 51,032.4 kg CO2-eq ha-1) sehingga budidaya memiliki neraca karbon positif yang berarti mengurangi GRK, yakni sebesar 24,933.9-54,493.1 kg CO2-eq ha-1 (rata-rata 44,577.0 kg CO2-eq ha-1). Berdasarkan regresi, tingkat C-org 4.8% dan dosis NPK (15-15-15) 440.7 kg ha-1 memberikan pengurangan (offsets) emisi GRK maksimum. Upaya mencapai budidaya ubi kayu rendah emisi diprioritaskan melalui pengurangan input pupuk misalnya dengan mengembalikan limbah biomasa budidaya.

Abstract

Photosynthesis rate plays a significant role in plant growth and development. A study was conducted to determine the best methods to grow sago planting materials from sago suckers. Photosynthesis rate, stomatal density, intercellular CO2 concentration, stomatal conductance, transpiration, sugar and starch content of the sago leaves from different methods of planting was determined. The field experiment was carried out at the Cikabayan Experimental Station from January 2020 to February 2021; the leaf morphology was conducted at the Microtechnical Laboratory and Testing Laboratory of the Department of Agronomy and Horticulture, Faculty of Agriculture, IPB University, Bogor, Indonesia. The treatments for the sago seedlings were immersion of the bare-rooted seedlings in water, immersion in water with media mix in polybags, transplanted to media mix in polybags, and immersion of bare-rooted seedlings for 4 weeks in water followed by transplanting to media mix in polybags. The study was arranged using a single factor a completely randomized block design, and quantitative data was analyzed using Microsoft Excel 2013 and the SAS. Stomatal density and photosynthetic rate were not significantly different between treatments. In contrast, the sugar content of immersed seedling without polybags for one month followed by transplanting to polybag had the best growth compared to those from other treatments, both at the nursery phase and post-transplanting phase. All planting methods resulted in good quality planting materials. At the nursery phase, sago seedlings immersed in water method grew the best; at the post-transplanting phases seedlings immersed bare-rooted for one month followed by transplanting to polybags grew better than those with other treatments

Abstract

Coal fly ash-bottom ash (FABA) is still possible to be used directly as a mixture of soil with other growing media in small-scale agriculture. This study aimed to determine and to identify the level of safety for the consumption of vegetable crops related to the adsorption of heavy metals due to the use of mixed FABA planting media. In this study, the proportion mixture of 6% FABA, 6% compost, and 8.6% fine coal (lignite) was applicated. The proportion ratio between FABA and soil was 1:15. The FABA media application was prepared for eggplant, chili, water spinach, spinach, mustard greens, and moringa vegetables. The study was conducted without any control treatment without FABA on the same soil type. As an alternative control, vegetables from local farmers, local markets, and supermarkets surrounding the study site were taken. The experimental results showed that the application of FABA did not increase nitrate and heavy metals content in vegetables. It can be concluded that vegetables grown on FABA media were safe and suitable for consumption in terms of acceptable daily intake of nitrate and various heavy metals, except for As intake in water spinach and mustard greens, which were recommended to be confirmed in further determination research.

Abstract

Tana Luwu area owns a relatively high diversity and production potential of sago, but it has not yet been managed optimally. This study aims to identify and analyze the diversity of morphological characteristics and the production of various sago accessions in Tana Luwu. Based on morphological characteristics, the sago palm in Tana Luwu is divided into two groups by the presence of thorns on the rachis and petioles. The presence of thorns has the largest coordinate axis angles, representing a higher diversity distance than other morphological characteristics. Some accessions show very high production potential, with a total production of 476.66 kg per dry tree starch. The average sago production in the six accessions is 276.40 kg per dry tree starch. Accessions with a yield potential > 200 kg per dry starch are observed in Kapa, Uso, Kasimpo, and Sabbe. Therefore, sago in these accessions is potentially developed to obtain superior varieties. Two significant morphological characteristics that contribute to sago production are stem height (r = 0.73) and the number of leaves (r = 0.78).
