Abstract

The aim of the research was to find out resistance of the five varieties of chili pepperto various concentrations of NaCl salt by Germination Test. The research wasconducted in the seed technology laboratory of the Faculty of Agriculture, Universityof North Sumatera on December 2011. The research used Randomized Block Designwith two factors and three replication. The first factor was variety, consisting of fivevarieties, namely Laris, Mario, TM 007, TM 999, and Hot Star. The second factor wassalt concentration, consisting 4 levels, namely G0(0 ppm), G1 (1000 ppm), G2 (2000ppm), and G3 (3000 ppm). The parameters observed in this research were germinationpercentage, germination rate, percentage of normal and abnormal seedlings,percentage of dead seeds, seedling fresh weight and seedling height. The resultsshowed that varieties significantly effected germination rate, percentage of deadseeds, seedling fresh weight and seedling height. While salt concentration did notshow any significant affect on all parameters. It can be concluded that among thevarieties tested, the Mario variety showed best tolerance to NaCl salt, the leasttolerance was Hot Star.Keywords : red chili, variety, NaCl, germination

Abstract

The objective of this research was to determine the right pruning times and spacing for the growth andproduction of yam (Pachyrhizus erosus (L.) Urban). This research used factorial randomized blockdesigned with 2 factors and 3 replications. The first factor was pruning time (P),namely withoutpruning (PA), pruning 7 weeks after planting (PB) and pruning 8 weeks after planting (PC) Thesecond factor was spacing (J) which consisted of 20 x 10 cm (J1), 20 x 15 cm (J2),20 x 20 cm (J3),and 20 x 25 cm (J4). The results showed that pruning significantly increased length of plant andnumber of branches. The treatment of spacing area influenced plant height. Interaction of pruningtimes and spacing increased plant height and number of branches.Key words : Yam, Pruning times, Spacing plants.
