Abstract

This study was conducted to determine irrigation volume based on pan evaporation and their effects  on growth, yield, irrigation water use efficency (IWUE) of chilli grown in sandponic system in the greenhouse. The amount of water used was based on pan evaporation. Irrigation treatments consisted of four coefficients, i.e. 0.5, 1, 1.5, 2 Epan. Plants were watered daily until soil reached field capacity during the first week. Irrigation treatments were applied on the second week until four months later. Total irrigation quantities varied from 9.4 to 37.8 L. plant-1. Chilli fruit yield varied from 3.98 to 90.51 g.plant-1. The highest total fruit yield and IWUE was obtained from 2 Epan treatment. Irrigation treatment had significant effects (P<0.01) on yield and there were positive linear relations between the yield and the amount of irrigation water applied. Irrigation volume significantly increased plant height, number of lateral branches, and number of leaves (P<0.01).Keywords: plant height, lateral branches, fruit

Abstract

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 lodging

Abstract

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 wind
