Abstract Yellow leaf curl disease caused by pepper yellow virus (PepYLCV) and transmitted the whitefly ( Bemisia tabaci ), becomes main problem in major horticultural crops, including chili pepper. The control of insect vector is crucial to overwhelm diseases. experiment was designed verify efficacy integrated focused on barrier crops healthy seedling techniques reduce crowdedness, prevalence v...
In no-tillage areas, cover crops are a continuous supply of organic matter and other positive improvements to the soil’s structural quality. We evaluated soil physical attributes in area cultivated with brassica on residues under no-tillage. Six coverages [1-Brachiaria (B), 2-Sunn hemp (S), 3-Pearl millet (M), 4-S + B; 5-B M; 6-S M] native (Cerrado biome), were for resistance penetration (RP), ...
A Tnt1-insertion mutant population of Medicago truncatula ecotype R108 was screened for defects in nodulation and symbiotic nitrogen fixation. Primary screening of 9,300 mutant lines yielded 317 lines with putative defects in nodule development and/or nitrogen fixation. Of these, 230 lines were rescreened, and 156 lines were confirmed with defective symbiotic nitrogen fixation. Mutants were sor...
The efficient use of green manure enhances sustainable nitrogen (N) cycling in agroecosystems. Appropriately utilizing the differences N and fiber between cultivars or harvesting times strengthens efficiency for subsequent crops. Therefore, it is necessary to clarify these differences. We clarified fibers from four sunn hemp (Crotalaria juncea L.) commercial at two after spring summer seeding t...
