Efisiensi Pemanfaatan Radiasi Surya, Pertumbuhan dan Produksi Tanaman Soba (Fagopyrum esculentum Moench.) di Ciawi Bogor

Solar Radiation Use Efficiency, Growth and Soba (Fagopyrum esculentum Moench.) Production in Ciawi BogorABSTRACT. Soba (Fagopyrum esculentum Moench) is potential alternative food source because of its chemical contents which are not so different from other main food sources. In its agronomical development, intensive and sustain research are needed to study solar radiation uses efficiencies, growth and yield of soba under different population an time planting. This research conducted from April to August 2000 at BPLP Ciawi – Bogor experiment station 415 meter top of sea level, 106 51 BT and 06 38 LS. Unit of research arranged by factorial completely randomized block design. The population factor consist of 3 level : 200 plants m-2 (P1), 160 plants m-2 (P2) and 133 plants m-2 (P3), and time of planting also consist of 3 levels : on April (T1), May (T2) and June (T3). Solar radiation uses efficiency at early growth to weeks after planting was higher at high population compared to low population, but after 5 weeks of planting or when maximum efficiencies, its higher on P2 compared P3 and P1. This showed that when grain filling and maturing, it is more intensive on low population then high population, however the anova for two factors at maximum efficiencies did not showed significant differences. Growth and yield of soba is better on high population compare to low population. This because on high population the microclimate condition and water availability is more adequate then on low population. There was no significant different on 1000 grain weight caused by two factors. For total yield P1 172,1 gm-2 was highest and significantly different then P2 143,6 gm-2 and P3 123,9 g m-2. Production cause by time of planting did not showed significant different between T1 and T2 but it did on T3.

Status of Rice Biochemical Composition under Lodging Treatment

Extreme weather conditions due to strong wind and high rainfall cause rice lodging. Lodged plants have lower photosynthetic rate and nutrient transport capacity which resulting in lower rice quality. However, physiological process of rice plant under lodging condition is rarely reported. Therefore the objective of this research was to evaluate the biochemical compounds of two rice varieties under artificial lodging treatment. IR64 and HIPA8 varieties were planted at the Experimental Farm in Leuwikopo, Bogor Agricultural University (IPB) in November 2016 to June 2017. At grain filling stage, rice hills were enforced to lodge using manual force until culm break. Analysis of untargeted biochemical compounds was conducted at Research and Development Institute, Laboratory of Regional Health, DKI Jakarta where rice culms from upper and below breaking position were compared. Results showed that rice culms had different biochemical compounds after lodging, especially in fatty acid, terpene, alkane, and steroid group. Lodging culms had a total of 22 to 25 compounds compared to 15 to 17 of the normal plants. It means that lodging stimulated different physiological process in rice plants. A decrease in fatty acid and an increase in the steroid level of lodged plants indicated an increase in oxidative stress of lodging condition. It is possible that low rice grain quality under lodging condition was caused by the changes in the plant physiological processes in response to the environmental stress.Keywords: extreme weather, metabolomics, oxidative stress, rice culm, rice lodgin

Analysis of Crop Water Requirement for Maize with Planting Hole System under Dry Climate Condition

Crop water requirement is an important factor to increase water use efficiency and avoid crop failure in dryland. A way to increase water use efficiency is by determining an irrigation interval scenario and utilizing a planting hole system. Research on the analysis of water requirement in the planting hole system with an irrigation interval for maize is still limited. Therefore, this study aims to analyze the level of water requirement for maize in dryland. This research was conducted in Camplong Village, Kupang District, East Nusa Tenggara (NTT) from January-May 2020. The design used was a split-plot of various treatments. There were three different techniques of applying fertilizer as the main plot, and two treatments of pruning maize leaves as sub-plots. The different treatments of fertilizer application includes: 1) mixing manure with rice husk charcoal (Ls+As), 2) separating manure from rice husk charcoal (Ls/As), 3) no addition of manure or rice husk charcoal into the planting hole (control). The sub-plots were divided into 2 treatments namely with leaf pruning (P) and without leaf pruning (TP). The water requirement was analyzed based on the FAO 56 approach with the production calculation in weight unit of tiles (ubinan). The results showed that 75% water efficiency was achieved or there was a water saving of 3,119 m3/ha/planting season when compared to conventional techniques. The highest maize productivity (7 tons/ha) was attained in treatment of mixing manure with rice husk charcoal with leaf pruning. The result indicated that this water savings may be used to expand the planting area to 3 ha

ANALISIS HUBUNGAN TINGKAT SERANGAN HAMA BELALANG KEMBARA (LOCUSTA MIGRATORIA MANILENSIS MEYEN) DENGAN CURAH HUJAN(ANALYSIS ON INFESTATION OF LOCUSTA MIGRATORIA MANILENSIS MEYEN BASED ON RAINFALL DATA)

Rainfall has an important role in the incidence of insect pests infestation, such as of locust grasshopper (Locusta migratoria manilensis Meyen). There are some provinces experience of locust grasshopper infestation, i.e. South Sumatera, Lampung, West and East Nusa Tenggara, North and South Sulawesi, West and Central Kalimantan. Generally, cropping season period of April–September and October-March shows a difference influence on the infestation of locust grasshopper. Most of districts in the provinces indicated that locust infestation increases in October–March cropping season, except in South Sulawesi it increases in April–September period. The analysis of correlation between rainfall and locust infestation applied in various timelags. The timelag was determined correspond with the life stage of locust, i.e. egg–hatching–nymphal–early imago–mating–active imago stage. The life stage of locust most influenced by rainfall and correspond with feed availability were active imago stage (in 9 districts) and egg stage (in 6 districts). The increase of rainfall during egg stage tend to suppress the infestation of locust, while during active imago stage the influence of rainfall tend to increase the infestation. The influence of rainfall closely correlated to locust infestation occurs in OKU, Central and South Lampung, West and East Sumba and West Ketawang

PERTUMBUHAN DAN PRODUKSI PAPRIKA PADA BERBAGAI INTENSITAS RADIASI SURYA DI DATARAN RENDAH, BATAM(GROWTH AND PRODUCTION OF SWEET PEPPER CULTIVATED UNDER DIFFERENT SOLAR RADIATION INTENSITY AT LOWLAND REGION OF BATAM)

An experiment has been conducted in Batam Island to study the response of sweet pepper which cultivated at lowland of 20 m asl, during November 2001 to May 2002. Five varieties have been used namely, Bangkok, Gold Flame, New Zealand, Spartacus and Tropica. Plants cultivated using hydroponic system under plastic house with ultra violet protection. The radiation of 100% (control) and it reduce of 25% and 50% used as treatment in order to determine the microclimate favourable for growing pepper in lowland. The results shown that reducing radiation intensity has influenced significantly on vegetatif growth, except leaf area index. The plants were grown under 100% and 25% radiation intensity performed taller with more branches compare to the plants under 50%. Variety of Spartacus has grew tallest than others. Stem diameter of control plants performed bigger than other plants, while reducing radiation intensity has no effect significantly to leaf area index. Experiment also revealed that reducing radiation intensity has significant effect on number and weight of peppers per plant, and thickness of flesh, compare to control. In general, Gold flame has produced best quality than others varieties although it has less number of fruits compare to Tropica

Adaptation of Wetland Rice to Extreme Weather

Climate change is believed to increase the intensity and the frequency of extreme weather events in reference to strong winds and heavy precipitations. The extreme event is defined as strong wind at speed of 50 km.h-1 and rain fall intensity 10 to 20 mm.h-1 or more .  This condition is detrimental to rice production as this may lead to lodging and flooding which normally occurs during the grain filling stage to harvesting resulting in lower yield and grain quality.  The. Simultaneous extreme events and critical rice growth occured more frequently due to increasing cropping season within a year in Indonesia. Therefore, it is important to mitigate and develop adaptation strategies in order to sustain rice production. Efforts to adapt to these extreme environmental conditions are mostly based on genetics and agro ecological approaches. Genetically, rice with strong hills, high aerodynamic with low water retention is desired. Agro-ecological manipulation is conducted through wind break application, planting arrangement to facilitate better sunshine penetration, to manage water level and planting calendar. Availability of weather station in the field is important to improve mitigation and continuous adaptation strategy against extreme weather events. Keywords: plant canopy architecture, climate change, heavy rainfall, lodging, strong win
