Abstract

The purpose of this activity is to increase the knowledge and skills of farmer groups to understand increasing the productivity of dry land by implementing corn-peanut intercropping cultivation. The program that has been implemented is the application of science and technology, with the stages of activities, namely: 1) dissemination activities on optimizing dry land with the corn-peanut overlapping technique, selecting peanut corn varieties that are adaptive to dry land and shade, as well as plant cultivation techniques on land dry. This activity was carried out with a system of lectures and discussions between the Extension Team and the Farmers' Group, and 2) a demonstration plot program involving farmers from the preparation/planning of the program to the implementation of the demonstration plots. Farmers directly participate in planting, maintaining, comparing, and evaluating whether the implemented program will provide benefits or not. The results of the activity showed that the farmers participating in the extension were very responsive to the corn-peanut intercropping dissemination activity. This is reflected in the enthusiasm of the participants in asking questions and the discussions between the participants or extension workers. In addition, participants were also active in participating in every stage of activities such as selecting good seeds, making demonstration plots, planting, stockpiling, weeding, pest and disease control, and harvesting activities. There is a process of technological transformation of corn-peanut intercropping on the dry land of Mbawi Village, Dompu District, Dompu Regency, with the hope that farmers will be able to utilize the dry land by intercropping. Intercropping can increase land productivity with a Land Equivalent Ratio (LER) value of 1.3 compared to corn monoculture and 3.1 compared to peanut monoculture

Abstract

This study aimed to determine the genetic diversity, heritability, and correlation of quantitative traits of the fifth generation (S5) of selfing lines of maize plants. The experiment was conducted in the dry land of Gumantar village, North Lombok, from February to May 2025. The design used in this experiment was a randomized block design. The number of treatments was 30 S5 lines. Each treatment was repeatedThe experiment was conducted twice, resulting in 60 experimental units. Eleven quantitative characters were observed, consisting of growth variables, yield components, harvest age, and yield. The experimental data were analyzed using analysis of variance at a significance level of five percent. The correlation between characters and yield was calculated using Pearson rank correlation. The results showed that six quantitative characters of the S5 line had narrow genetic diversity and six characters had moderate criteria; with genetic diversity coefficients ranging from 1.56 for harvest age and 13.02 for yield. The broad-sense heritability of 1,000-grain weight was high, six characters were moderate, and the rest were narrow. The yield character was strongly correlated with the harvested dry cob weight per plant; with cob length being moderately correlated; four characters were weakly correlated, and the other characters were not correlated with yield. The plants selected to form the sixth selfing generation were taller plants with narrower leaf angles and flowering simultaneously
