Abstract

Weeds are very detrimental to maize because they compete for light, water and nutrients. This observation aims to determine the composition and structure of weeds on narrow leaves on corn cultivation land in the lowlands, namely in the Saworatap area, Gedangan subdistrict and the highlands in Randuagung village, Wonosari subdistrict, Malang. This observation was carried out in November 2024. The method used in this observation was survey and sample collection techniques were purposive sampling, making plots measuring 1 m x 1 m with a total of 6 plots in both locations. In the lowlands, the composition of grass weeds is only two species, namely Eleusine indica and Setaria verticillata which belong to the Poaceae family. The composition of grass weeds in the highlands has a higher species diversity, namely six species divided into two families. Weed species belonging to the Poaceae family are Echinochloa colona, ​​Setaria verticillata, Eleusine indica, and Chrysopogon zizanioide, while grass weeds belonging to the Cyperaceae or enigma family are Cyperus iria and Cyperus rotundus.

Abstract

Weed Species Diversity in Lowland and Upland Sugarcane (Saccharum officinarum) Fields: Sugarcane (Saccharum officinarum L.) cultivation began intensively on the northern coast of Java Island from the 1830s to the 1870s. Because of the presence of weeds that can interfere with the growth of major crops such as sugarcane, it is important to identify and manage these weeds to maintain productivity levels. Weed competition for nutrients, water, and light can significantly reduce crop yields. Agricultural land in Indonesia is divided into two main categories: lowland and upland, each with different environmental characteristics and weed species. Identification and utilization of weeds in lowland and upland sugarcane fields are essential for effective land management and increasing agricultural sustainability. Practices such as integrated weed management, which involves cultural, mechanical, biological, and chemical control strategies, play an important role in controlling weeds and ensuring maximum crop productivity. Factors that influence weed diversity in these areas are complex, including environmental factors such as temperature, humidity, and soil type, as well as agricultural practices such as pesticide use, crop rotation, and soil management. Collaborative efforts in implementing various weed control methods are essential in addressing weed challenges and optimizing sugarcane production in various environments.
