Abstract

This research was aimed to evaluated the interaction effect of  plant spacing on the growth and yield of six lowland paddy  variety based on cuantitative characters.This research was conducted at  Jembatan Mas. Pemayung District. Jambi Province. This research was arrangement on Split plot  Design with Randomized block design (CRBD). The first factor as main plot : spacing J1 (30x20 cm), J2 (30x15 cm), J3 (30x10 cm), the second factor variety as subplot  :  V1 ( IR-42), V2 (Cisokan), V3 (IR-64), V4 (Batanghari), V5 (Wayrarem), V6 (Limboto). The Results showed that there were no interaction effect  between spacing and paddy variety. There are significantly simple effect of spacing to number of tillers and time of   flowering. Simple effect of Variety,have sfignificantly effect of variety to all growth and yield component. The highest paddy yield was achieved at Variety IR 42 ( 4.55 ton ha-1).   Key words : genetic variation, quantitative characters.

Abstract

Chili is a vegetable that has high economic value, but to increase production is hampered by high attacks of pests and diseases. One effort to improve it is by using mulch and selecting superior varieties of chili plants. The study aimed to examine the effect of Black Silver Plastic Mulch (MPHP) on the growth and yield of two chili varieties (Capsicum annuum L). The study used a Randomized Block Design (RBD) with one factor of combination of variety and type of mulch.. The combination of two varieties and mulching is as follows: P1 = (Mario variety + without MPHP), P2 = (Jatilaba variety + without MPHP), P3 = (Mario + MPHP variety), P4 = (Jatilaba + MPHP variety). To see the effect of treatment, the data were processed statistically by analysis of variance, and for further tests using the Smallest Significant Difference Test (LSD) at the level of α = 5%. The combination of the use of MPHP and two chili varieties affected plant height, number of fruit crops, yield of 2X yields, and weight vanished. The use of Mario varieties given MPHP can increase yields on variable height of chili plants, number of fruit crops, yields and weight loss. Chili Mario varieties more resistant than Jatilaba using MPHP .
