“…It must be remembered that the beads declined slightly more rapidly with time at Long Ashton but, even when this was taken into account, there was a faster decline rate for a number of species, including C. fontanum , C. album , F. officinalis , G. aparine and P. aviculare. Burnside et al . (1977) have also reported higher decline rates for seeds of Sorghum bicolor (L.) Moench in lighter soils but, surprisingly, there seem to be few other published reports on this issue.…”

Summary Two experiments have investigated the persistence of 16 arable, annual broad‐leaved weed species over 6 years in a silty loam and a clay soil. Small plastic beads were included as an ‘inert’ comparison. Seeds were broadcast in October on to plots at the start of the experiment, and these were either tine cultivated or ploughed annually thereafter. Plots were sown with either spring or winter wheat. As far as possible, weed seeding was prevented each year. For some species, the seed decline appeared to be slower on the ploughed plots than on the tined plots and in the winter wheat compared with the spring wheat. Seed decline also tended to be slower on the clay soil at Rothamsted than on the silty loam at Long Ashton. Some species declined rapidly (e.g. Brassica napus, Chrysanthemum segetum, Galium aparine, Galeopsis tetrahit), with annual decline rates in excess of 58%, whereas others declined very little (e.g. Papaver rhoeas decline rate 9%). Most of the other species had decline rates between 20% and 40%. The results are discussed in relation to the development of population dynamics models to predict long‐term consequences of alternative weed management strategies.

“…Robert [40], Robert and Feast [41] also observed that weed seeds in shallow soil layers or exhumation of the buried seeds to the shallow layers increase the chances of mortality of the weed seeds as compared to the deeper ones. Actually, the burial of weed seeds in deeper layers provide more or less constant soil conditions, and longevity of these seeds may be more closely related to the adaptations by the seeds to this condition itself [42].…”

Changes in the Weed Seed Bank in Long-Term Establishment Methods Trials under Rice-Wheat Cropping System

et al. 2020

The rice-wheat cropping system in the Indo-Gangetic Plains is the backbone of food security in India. In the 1990s, due to the scarcity of resources, the traditional Crop Establishment (CE) method shifted from Conventional Till Puddle Transplanted Rice (CTPTR) to CT Direct Seeded Rice (CTDSR) and Zero-Till DSR (ZTDSR) in paddy; and in wheat, from Conventional Till Wheat (CTW) to Zero Till Wheat (ZTW), with residue retention in rice (RRR) or in both rice and wheat (RRRW). Shift in CE methods led to change in Weed Seed Bank (WSB) dynamics and ultimately affected the weed management program. After five years of field trials, soil samples were drawn as per 2-factors factorial randomized block design. Factor-I comprised 4-CE methods, whereas factor-II consisted of 3-soil depths (0-10, 10-20 and 20-30 cm). Results showed CTPTR-CTW and ZTDSR-ZTW (RRRW) record the highest seed bank (SB) of grasses, sedges and BLWs as total weeds, in general; and predominant weeds like Echinochloa spp., Ammania baccifera, Commelina benghalensis and Digitaria sanguinalis, in particular. It also showed the higher species richness (D Mg ) and Shannon-Weaver (H') indices. CTDSR-CTW and CTDSR-ZTW (RRR) show the lowest WSB and at par with Shannon-Weaver (H') index; further, lowest species richness (D Mg ) under CTDSR-CTW. Species Evenness (J') and Simpson index (λ) vary non-significantly with CE methods. Furthermore, 0-10 cm soil depth showed the highest SB of different category of total weed, predominant weeds as well as higher values of D Mg , H', and λ; whereas reverse trend was observed in Whittaker Statistic (β W ). Interaction between CE methods and soil depth revealed most of WSB lying on the top layer in case of ZTDSR-ZTW (RRRW) and CTDSR-ZTW (RRR); while CTPTR-CTW showed almost uniform WSB distribution, and in case of CTDSR-CTW, a gradual decrease in WSB with soil depth.

“…It can grow to a height of 1-3 m and produce over 1000 seeds per panicle. Seeds on mature panicles may shatter before the crop is harvested and can remain viable for up to 13 years when buried in soil (Burnside et al 1997). Shatter cane can vigorously compete with all crops for light, nutrients, and water (Burnside 1990;Fellows & Roeth 1992).…”

A field study was conducted to evaluate the effects of shatter cane (Sorghum bicolor) and soybean (Glycine max) densities on soybean seed yield and to quantify interspecific and intraspecific interference coefficients. The relations between soybean seed yield per plant and shatter cane density at different densities of soybean and also with soybean density at different densities of shatter cane are well described by the reciprocal equations. Soybean seed yield per unit area decreased with increasing shatter cane density. The highest yield loss (57%) was relative to 50 and 12 plants/m 2 of soybean and shatter cane densities, respectively. Optimum soybean densities on the basis of maximum soybean seed yield per unit area at 0,4, 8, and 12 plants/m 2 of shatter cane were achieved at 50, 34, 32, and 36 plants/m 2 , as estimated by the asymptotic or parabolic relations between soybean seed yield per unit area and soybean densities at different shatter cane densities. Shatter cane was a stronger competitor than soybean, as a shatter cane plant was equal to 2.5 soybean plants, based on soybean seed yield. In contrast, a soybean plant was equal to 0.18 of a H03096;
