Abstract

The obstacle to rearing cattle with a herding system on dry land is the unstable availability of feed because the potential for forage production is low. The reason is because dry land is not managed intensively. The research was conducted with the aim of evaluating the application of a monocrop cropping pattern system and intercropping between corn and beans in dry land. The experiment was designed with a randomized block design consisting of nine treatments, namely monocrops of corn, peanuts, soybeans, red beans and cowpeas, as well as intercropping between corn and peanuts, soybeans, red beans and cowpeas. The results of the research show that in the management of a monocrop cropping system and intercropping between corn and beans, weed diversity was found to be quite high, namely 20 families with 39 species, which included 10 species of Poaceae, 9 species of sedges and 20 species of broadleaf. The characteristics of the weeds found were high in species diversity, the ability to spread evenly throughout the corn and bean planting area was high and the ability to dominate the planting area was also high. The best quantity and quality of forage products as raw materials for animal feed are obtained from moorland management with monocrop planting patterns and intercropping of corn with peanuts and cowpeas. In this moorland management system, the potential for forage products obtained is 10.81 – 13.60 kw ha-1 day-1 and the potential land capacity for raising cattle is 5.21 – 5.53 ST ha-1.

Abstract

The research aims to examine the diversity, dominance, equality, and frequency of weed species and to assess the potential of the soil as a weed seed bank in different types of plantations in arid regions. Descriptive research was conducted on plantations for coconuts, cashews, cocoa, coffee, and mixed gardens. Experiments to investigate the potential of the soil as a seed bank for weeds were carried out in the greenhouse of the Agricultural Faculty of Mataram University using a completely randomized one-factor design with five types of soil from the five plantations. The research results show that coconut plantation land and mixed gardens have the highest weed species diversity index and evenness with low dominance. In contrast, cashew, cocoa, and coffee plantation lands show high species dominance with low diversity and evenness, resulting in five highly dominant weed species, namely: P. Conjugatum, A. Compressus, D. Esculentum, B. Spicata, and S. torvum. Coconut plantations and mixed gardens show a significantly higher number of species, populations, and the dry biomass weight of weed grasses and reeds compared to almonds, cocoa, and coffee, as well as a faster growth time of the weed seed bank, reflecting the ecological conditions that support the soil's potential as a weed seed bank.
