Effect of soybean variety and pest management on the sustainable production

Abstract

Pests are one of the limiting factors in increasing soybean production. Pest control carried out by farmers using pesticides is feared to threaten the sustainability of soybean production in Indonesia. This study aimed to identify the effect of different pest management systems and various soybean varieties on pest population dynamics, abundance and diversity of natural enemies, plant damage, and soybean production. A split plot design with three replications was applied, where the main plot was pest management systems i.e. (1) control (which received neither chemicals nor integrated pest management), (2) chemical control, and (3) integrated pest management, and the sub-plot was soybean varieties i.e. (1) Anjasmoro, (2) Demas 1, and (3) Dering 1. Results indicated that variety affects pest diversity and abundance, however, it affected leaf damage, pod damage, and production. The pest management systems influenced the diversity and abundance of pests and natural enemies, plant damage, and production. Interaction between variety and pest management system affected plant damage. We conclude that the use of resistant varieties combined with integrated pest management could reduce plant damage, maintain the natural enemy population, and optimize soybean production.

Advantages of early-maturity soybean varieties as a farmer adaptation effort to climate change in Grobogan Regency

“…Pesticides can suppress pest to reduce yield losses [37,38]. However, pesticides are applied when the pest population exceeds the control threshold [39]. Farmers cultivating Biosoy are not charged irrigation dues, while Anjasmoro is charged IDR 68,061.…”

The characteristics of several varieties and the effect of cropping management design on the level of pest damage and seed yield of soybeans in rainfed lowland rice fields

“…Trichomes as a morphological feature of soybean plants have characteristics that can influence the behavior of insect pests. The type of variety affects the diversity and abundance of pests, which also has an impact on the level of leaf damage, pod damage, and overall productivity (Faiz et al, 2021;Aryati and Ulina, 2023). Trichomes are a part of the plant that are above the plant epidermal tissue with various functions.…”

“…Similarly, as mentioned in the study by Mardian et al (2019), the Legowo cropping design has a much better population and productivity when compared with the conventional cropping design. One way to control soybean pests in rainfed rice fields is to carry out appropriate cultivation management using pest-resistant varieties (Aryati and Ulina, 2023). The management of spacing is an environmentally friendly technology design that has a positive impact on the environment and the sustainability of plant productivity (Yan et al, 2020;Singh and Krishnaswamy, 2022).…”

“…Soybean cultivation design management techniques and the use of superior varieties are the ways to control pests in an environmentally friendly manner (Aryati and Ulina, 2023). Appropriate management followed by the use of environmentally friendly technologies has a positive effect on the environment and the sustainability of plant productivity (Yan et al, 2020;Singh and Krishnaswamy, 2022).…”
