<![CDATA[The crossing between Srikandi Putih corn varieties which have high production potential and protein content with local pulut corn which has high amylopectin levels is expected to produce superior offspring. This study aimed to determine the character of F1 and F2 results of crossing of Srikandi Putih variety with local Pulut corn (waxy corn) at different planting distance. This research was conducted in the Experimental Farm of the Bajeng Cereals Crop Research Institute, South Sulawesi Province, from May-August 2018. This method used was Split Plot Design, consisting of Main Plots, namely planting distance (70 cm x 20 cm and 70 cm x 30 cm) and Sub Plots, namely Varieties (Srikandi Putih, Local Pulut, F1 and F2). The results showed that genotype significantly affected plant height, seed production per hectare, amylopectin content and seed protein content, and genotype had very significant effect on number of leaves, ear length, ear diameter, seed weight per plant and seed weight per plot. Planting distance has a very significant effect on seed weight per plot and the best was 70 cm x 20 cm. This is due to the number of populations at 70 cm x 20 cm planting distance more than 70 cm x 30 cm. Genotype interaction and planting distance have a very significant effect on seed weight per plant. Srikandi Putih variety was the best genotype for growth, production and protein content parameters while the best amylopectin content parameter was local Pulut. Srikandi Putih variety was potential for growth and production as well as high protein content, but low amylopectin levels while local Pulut has high potential for amylopectin levels but low growth and production potential. The best combination of growth, production, protein and amylopectin content was in F1 and F2 genotypes.]]>

<![CDATA[Plutella xylostella is one of cabbage’s main pests. Botanical insecticides as alternative of chemical insecticides need to be expand, one of them is mahogany seed extract. Mahogany seed exctract contains saponin and flavonoid as reported mortal to P. xylostella. This study aimed to know the effective concentration of mahogany seed extract to manage P. xylostella different larva instar and to know LC50 value of mahogany seed extract to P. xylostella. This method used was completely randomized experimental design (CRD). Two factors used were mahogany seed exctract concentrations (0 gL-1, 5 gL-1, 10 gL-1, 20 gL-1, and 40 gL-1) and larva instar (first and third instar). Each treatment repeated four times. The results showed that percentage of larva mortality first instar higher than third instar. Concentration 20 gL-1 of mahogany seed exctract effective to kill first instar larva, and concentration 40 gL-1 effective for third instar. Percentage of pupa mortality highest in concentration 10 gL-1 for first instar and concentration 40 gL-1 for third instar larva. Antifeedant increased as concentration given, while the eating ability that higher in third instar was decreased. LC50 for first instar larva was 2,6 gL-1 and third instar was 13,7 gL-1, meaned that mahogany seed extract more toxic to first instar than third instar larva.]]>

<![CDATA[Post-harvest with storage are important to maintain the supply of rice. One of the obstacles found in storing rice is the attack of Sitophilus oryzae which is responsible of causing yield loss. The attack of S. oryzae on rice can be caused by storage temperature and protein content on rice. The objective of this research was to determine the attack rate of S.oryzae in several paddy varieties and different storage temperatures. The research was conducted in Laboratory of Pest and Plant Disease Faculty of Agriculture Universitas Sebelas Maret from March-June 2019. The method used was Nested Design with 2 factors and 3 replications. The treatments given were storage temperature (29oC, 39oC, 49oC and 59oC) and paddy varieties (brown rice, black rice, Rojolele and IR64). Observation variable were number of imago, pupae, larvae, percentage of decrease in rice weight, broken rice and rice powder. The results showed that S. oryzae was able to survive at a storage temperature of 29oC. Storage temperatures which increased by more than 29°C causing mortality of S.oryzae up to 100%. The longer storage time will cause an increase in population and S.oryzae attack rate.]]>

<![CDATA[Mechanical control as an effort to reduce Erionata thrax attacks needs to develop of them was torning the leaves. The objective of this research was to determine the effect of leaf torning on the intensity of the damage and determine the level of E. thrax attack damage in various cultivars. This research was conducted in Semarang, Central Java from September-December 2018. This research used a field experiment method with four treatments of tearing distance of 0 cm, 20 cm, 30 cm, and 40 cm in four banana cultivars, namely Mas Kirana, Ambon, Kepok, and Raja Bulu. The result showed that leaf damage was related to torning distance, but not to the cultivars. The value of regression between torning distance and leaf damage was very low. The torning distance of 40 cm had the highest leaf damage, number of larvae populations, and number of leaf rolls. The torning distance of 20 cm reduced the leaf damage, the number of larvae populations and the number of rolls. The lowest leaf damage is in Mas Kirana cultivar and the highest leaf damage is in Raja Bulu cultivars. Raja Bulu cultivar had the highest attack intensity.]]>
