“…No weeding compared to herbicides and manual hoeing resulted in lower values for all crop parameters except total weed dry weight ( Table 4 ). The increase of which would be largely related to the nitrogen applied which would have benefited nitrophilous weeds more than the crop [ 40 , 41 ]. Manual hoeing performed at 3–6 WAS did not reduce maize plant density.…”

“…Leaf nitrogen content is suspected to correlate with cytokinin and abscisic acid hormonal metabolism (Luo et al 2018). Nitrogen is the main contributor to amino acid and protein synthesis (Perchlik and Tegeder 2018) and is an influential nutrient in plant growth (Rahayu et al 2019). Plants could not exploit all of the nitrogen available in nature.…”

Abstract. Permanasari I, Sulistyaningsih E, Kurniasih B, Indradewa D. 2023. Morphophysiological and yield traits of soybean varieties tolerant of intercropping with maize. Biodiversitas 24: 3872-3880. Not all soybean varieties grow optimally when intercropped with maize. Previously, we identified seven varieties (i.e., "Demas 1", Dena 1", "Dena 2", "Derap 1", "Devon 1", "Devon 2", and "Wilis") and two (i.e., "Dega 1" and "Mahameru") as tolerant and intolerant of intercropping based on selection indices and yield. This research aims to determine the morphophysiological and yield traits of tolerant and intolerant soybean groups intercropped with maize. The study used a randomized complete block design with three blocks as replications, and conducted from October 2019 to February 2020. Results showed that light intensity in the intercropping system had decreased by 19.91% relative to that in the monoculture system at 7 weeks after planting. The tolerant group displayed significant gains in seed weight per plant (143.66%), total biomass (50.04%), harvest index (53.33%), total number of pods and seeds per plant (119.39% and 128.86%), leaf nitrogen uptake and content (20.83% and 6.44%), chlorophyll-a:b ratio (7.20%), and stem diameter (7.65%) than the intolerant group. Correlation analysis revealed that leaf nitrogen content showed the highest correlation and significantly contributed to seed weight per plant in the tolerant and intolerant groups. Seed weight in the tolerant group was mainly affected by morphological (total biomass and harvest index), physiological (leaf nitrogen content), and yield components (number of pods), whereas that in the intolerant group was influenced only by physiological parameters (nitrogen content). Nitrogen content was considered suitable as a selection indicator for determining the seed yield of intercropped soybean varieties. Furthermore, using soybean tolerant groups for intercropping may be a solution to increase soybean production in Indonesia.

“…Penentuan jenis gulma dilakukan dengan mengacu kepada buku manual identifikasi gulma (Naidu, 2012;Sriyani et al, 2014). Selanjutnya data gulma digunakan untuk menetapkan dominansi gulma melalui nilai summed dominance ratio (SDR) menurut Janiya dan Moody (Rahayu et al, 2019).…”

Maize is a second important food crop, its yield is the raw material for the feed industry. As for other crops, maize can not avoid weed association and interference. Weed may cause farmers’ economic loss. An experiment to determine the efficacy of thiencarbazone methyl+isoxaflutole herbicide and its effects to control weeds and maize yield was conducted from October 2022 to February 2023 at Ultisol of Universitas Andalas, Limau Manis, Padang. The experimental units were laid out according to a completely randomized block design (CRBD) with 10 treatments and three replications. The treatment was different types of weed control namely: no weeding, various doses of herbicide thiencarbazone-methyl 90 g L-1+isoxaflutole 225 g L-1 i.e 250 mL ha-1, 300 mL ha-1, 350 mL ha-1, and 400 mL ha-1 applied at 2 and 10 DAP, respectively, and manual weeding. Herbicide thiencarbazone-methyl 90 g L-1+isoxaflutole 225 g L-1 effectively controlled Erechtites valerianifolia, Oxalis barrelieri, and Asplenium rhizophyllum. Herbicide at 350 mL ha-1 applied dose at 2 DAP reduced weed dry weight per m-2 as much as 93% at 6 WAP. Weed control by herbicide application increased 72.20% of maize yield per ha compared to the no-weed-control treatment group without causing phytotoxicity on maize plants.ABSTRAK Tanaman jagung merupakan tanaman pangan penting kedua dan menjadi bahan baku industri pakan. Seperti tanaman lainnya, tanaman jagung juga tidak dapat terhindar dari interaksi dan asosiasi dengan gulma. Keberadaan gulma pada pertanaman jagung dapat menimbulkan kerugian ekonomis. Penelitian dilakukan untuk mengetahui pengaruh efikasi herbisida thiencarbazone-methyl+isoxaflutole yang diaplikasikan pada waktu berbeda terhadap pengendalian gulma dan hasil tanaman jagung telah dilaksanakan pada bulan Oktober 2022 sampai Februari 2023 pada tanah ultisol kampus Universitas Andalas Limau Manis, Padang. Penelitian dilaksanakan menggunakan rancangan acak kelompok (RAK) dengan 10 perlakuan dan 3 ulangan. Perlakuan adalah tanpa pengendalian gulma, berbagai dosis herbisida thiencarbazone-methyl 90 g L-1+isoxaflutole 225 g L-1 yaitu 250 mL ha-1 , 300 mL ha-1 , 350 mL ha-1 , dan 400 mL ha-1 yang masing-masing diaplikasikan pada 2 dan 10 HST, dan pengendalian gulma secara manual. Herbisida thiencarbazone-methyl 90 g L-1+isoxaflutole 225 g L-1 dosis 250 hingga 400 mL ha-1 efektif mengendalikan gulma Erechtites valerianifolia, Oxalis barrelieri, dan Asplenium rhizophyllum. Herbisida dosis 350 mL ha-1 diaplikasikan 2 HST menurunkan hingga 93% bobot kering gulma m-2 pada 6 MST. Pengendalian dengan herbisida dapat meningkatkan hasil jagung per ha sebesar 72,20% dibandingkan perlakuan tanpa pengendalian gulma tanpa menimbulkan gejala fitotoksisitas pada tanaman jagung.
