Abstract

Ultisol soil has a high aluminum content and is often attacked by blast disease, which inhibits the growth and production of upland rice plants. This study aims to obtain varieties and lines of upland rice tolerant to aluminum stress and blast disease planted on Ultisol Lampung. The study used a randomized complete block design (RCBD) with 8 types of lines and 4 varieties; The experiment was repeated three times. The results showed that line 2 (PL47)-7 was better than the other lines as indicated by productive tillers of 16.8 stems, flowering age of 50% (72.12 days), number of filled grains per panicle of 75.56 grains, the weight of 100 grains of 2.70 g, yield per harvest plot of 172.51 g/ 10 m2, Aluminum stress has a score of 3 with normal growth indicators, but there are white or yellow spots on the tips of old leaves (20–39%), and neck blast has no symptoms with a score of 0.

Abstract

The presence of weeds in paddy rice crops results in a decrease in yields. Appropriate weed control methods are needed as an effort to reduce potential production losses. The first step to find out the right way to control weeds is by identifying the dominance and diversity of existing weeds. This study aims was to determine the dominance and diversity of weeds in organic and conventional paddy fields. This research was conducted in organic and conventional paddy fields of Lampung State Polytechnic, Lampung Province from October to December 2022. Weeds were observed on the 0.5 m2 quadrant method with 10 replications. The data were analyszed to find the Summed Dominance Ratio (SDR) value to determine the dominant weed and the Shannon - Wiener index (H') value to determine weed diversity. The identification results showed there were 11 weed species in organic land and 7 weed species in conventional land. Broadleaf weeds were the most dominant weeds in both land areas, namely Monochoria vaginalis in organic rice fields and Spenochlea zeylanica in conventional rice fields. The results of the weed diversity index analysis showed that in both land areas fall into the category of moderate diversitywith the value of  2.31 in organic rice fields and 1.93 in conventional rice fields.
