“…Another reason may also be caused by similar of physical and chemical characters on corn seed. Although, the characters of corn seed are not merely affected by maize genotypes but also the soil condition which have availability to support plants on the absorption of nitrogen fertilizer (Kuswanto, Wicaksono, Sudakir, & Begliomini, 2013). In addition, the defense mechanism of plants from pests is also influenced by factors such as physical or chemical plant phenolic compounds.…”

One possibility to protect the maize from storage pests is by developing genotypes that resistant to maize weevil (Sitophilus zeamais Motsch). The research was aimed to evaluate the susceptibility of several maize genotypes including local variety to the maize weevil. Six genotypes i.e. SJA, G10-12-20, G10-1-3, G10-1-7, G10-1-20 and G10-1-17 and Tosari as local variety were used. No-choice assay under laboratory condition with observed variables was laid an egg and F 1 progeny number, the median time of development and weight loss of infested kernel. The susceptibility index was assessed using Dobie's susceptibility index. Results showed that the number of eggs laid by five females and infested samples weight loss were not significantly different between six maize genotypes as well as local variety. In contrast, the number of F 1 progeny emerged was significantly different. Based on the susceptibility index, the maize genotype of G10-1-3 and G10-1-17 were resistant to the weevil. While other maize genotypes and local variety were considered as moderate resistant. Based on analysis of chemical and physical characteristic revealed that maize genotypes with higher of the total phenolic compound and physical hardness tend to resist from weevil damaged.

“…The increase of Pyraclostrobin concentration increased the chlorophyll index on each treatment of night temperature. Thus was because of Pyraclostrobin that was able to increase the enzymatic activities of nitrate reductase (Kuswanto et al, 2013). This enzyme plays its role in forming nitrogen, so that it can increase the chlorophyll content and nitrogen in leaf (BASF, 2013).…”

“…Results of a study conducted by Kuswanto et al (2013) showed that application of Pyraclostrobin increased amylose from 10.85% to 18.5% and increased starch and protein. The increase of temperature by 4 o C at night decreased the percentage of starch, amylose, and amylopectine.…”

Abstract:Rice productivity is having a problem related with climate change phenomenon, mainly the global warming. The rising of temperature in some country threat the rice production. The increasing of temperature is a major limiting factor that affects yield through the growth and development of rice plant. This study was aimed to examine the response of rice (Oryza sativa L.) to elevated night temperature with the application of Pyraclostobin. A glasshouse experiment that was conducted from March to August 2015 at Brawijaya University Research Station of Jatikerto -Malang, used nested plot design with three replications and two treatments. The first treatments were the night temperature level (normal temperature, increased 2 o C, and increased 4 o C). The second treatments were the concentration of Pyraclostrobin (0 ppm, 400 ppm and 800 ppm). Results of the study showed that the increase of temperature at night for about 2 o C and 4 o C, as well as application of Pyraclostrobin, affected growth and yield of rice. Application of Pyraclostrobin by concentrations of 400 ppm and 800 ppm effectively reduced yield loss by increasing night temperature of 2 o C, which resulted in 20.20% and 24.93%, respectively, in comparison with the control; while the increase of night temperature by 4 o C have resulted 26.86% and 33.33% in comparison with the control. Pyraclostrobin was effective in maintaining percentage of the filled spikelets by the increase of temperature at night for about 2 o C and 4 o C.
