“…There have also been antagonistic effects on human and cattle health due to agrochemicals residue in food products (Kumar and Bohra, 2006). Multiple health hazards and irreparable environmental pollution have occurred from the use of inorganic fertilizers (Hinds et al, 2016). Modern agricultural practices, such as organic or ecological or sustainable agriculture, are being developed to reduce the adverse effects of synthetic fertilizers and pesticides on human health and the environment (Aksoy, 2001;Chowdhury, 2004).…”

The present research was undertaken with the aim of justifying the effect of morphological, physiological, and nutritional properties in organically produced zucchini squash. The experiment consisted of two factors: three levels of pruning (P0 = no pruning, P1 = primary pruning at 20 days after transplanting (DAT), and P2 = secondary pruning at 30 DAT) and four levels of vermicompost application (V0 = control, V1 = 5 t/ha, V2 = 10 t/ha, and V3 = 15 t/ha). The results demonstrated that morphological parameters, reproductive components, and yield and proximate compositions were significant differences among the treatments. Increased male and female flower production were recorded from primary pruning with 10 t/ha vermicompost treatment plots compared with control treatments. Finally, increased fruit number, individual fruit weight, fruit length, fruit diameter, total yield, carbohydrate, protein, crude fat, fiber, and ash were reported from the same treatment combination (P1V2). Taken together, 10 t/ha vermicompost with primary pruning appear to provide maximum output in terms of yield and nutrient value compared with other treatments.

“…Graham and Crabtree (1987) and Vrabel et al (1981) reported that mowing was often inferior to chemical control for living mulch suppression. In zucchini (Cucurbita pepo L.) grown with a living mulch of sunnhemp (Crotalaria juncea L.), yield losses were reduced when the living mulch was cut to a height of 20 cm rather than 45 cm (Hinds et al 2016). Mechanical control of living mulches could also be improved by the introduction of novel methods.…”

Integrated management of living mulches for weed control: A review

Living mulches are cover crops grown simultaneously with and in close proximity to cash crops. Advantages of living mulches over killed cover crops may include increased weed suppression, erosion and leaching control, soil health, and resource-use efficiency. Advantages of living mulches over synthetic mulches may include enhanced agroecosystem biodiversity and suitability for a wider range of cropping systems. A major disadvantage of this practice is the potential for competition between living mulches and cash crops. The intensity and outcome of mulch-crop competition depend on agroecosystem management as well as climate and other factors. In this review, we consider the management of living mulches for weed control in field and vegetable cropping systems of temperate environments. More than 50 years of research have demonstrated that mechanical or chemical suppression of a living mulch can limit mulch-crop competition without killing the mulch and thereby losing its benefits. Such tactics can also contribute to weed suppression. Mechanical and chemical regulation should be combined with cultural practices that give the main crop a competitive advantage over the living mulch, which in turn outcompetes the weeds. Promising approaches include crop and mulch cultivar selection, changes to planting time, density, and planting pattern, and changes to fertilization or irrigation regimes. A systems approach to living mulch management, including an increased emphasis on the interactions between management methods, may increase the benefits and lower the risks associated with this practice.

“…Type 1 fb Type 1, Type 2 fb Type 1, and Type 2 fb Type 2 were similar to each other and to the untreated check throughout the season, while living mulch in Type 1 fb T ype 2 was shorter (P = 0.0005 in mid-July; P < 0.0001 in late July; P < 0.0001 in early August; P < 0.0001 in late August). Reductions in living mulch height are expected from herbicide applications and are positive outcomes because living mulch height has considerable influence on crop yield (Greenland 2000;Hinds et al 2016;Zandstra and Warncke 1993). Tall living mulches can easily become too competitive with crops by shading both the side and top portions of the crop canopy.…”

Significance of herbicide order in sequential applications to target weeds in a sunn hemp living mulch

Striking a balance between the weed control capacity of living mulches and their competition with the main crop is complex. At rates that avoid severe injury to living mulch, herbicides may reduce their vigor while simultaneously contributing towards weed control. In a two-year field study carried out in Freeville, NY, USA, we evaluated the effects of various combinations consisting of two herbicides, applied sequentially at reduced rates, on the growth of a sunn hemp living mulch and weeds (including common lambsquarters, common purslane, hairy galinsoga, and Powell amaranth). When a herbicide with primarily POST activity (Type 1) (e.g., rimsulfuron, 0.005 to 0.007 kg ai ha-1) was applied first, performance of sunn hemp (1.7 to 3.9 tons ha-1 dry biomass; 10 to 88% groundcover) was poor and weed growth (25 to 62% groundcover) was high, likely because sunn hemp, severely injured at a young growth stage, was outcompeted by weeds. A follow-up application (approximately two weeks later) of a herbicide with primarily PRE and residual activities (Type 2) (e.g., metribuzin, 0.05 to 0.15 kg ai ha-1), with a surfactant to enhance its POST activity, had little effect on established weeds. However, because sunn hemp was already 20 cm tall at weed emergence, applying a Type 2 herbicide first, did not cause severe injury to sunn hemp and reduced weed pressure, thereby also enhancing sunn hemp performance (3.8 to 6.1 tons ha-1 dry biomass; 85 to 94% groundcover). Moreover, the follow-up application of a Type 1 herbicide affected the smaller weeds more (4 to 21% groundcover) than the better-established sunn hemp. Our results demonstrate that an appropriate sequence of herbicides at reduced rates may be important to control weeds while maintaining a healthy living mulch stand.
