“…The results show that in Zea mays seeds, the roots and stems, according to Figure 6, may have been affected by the compounds present in the BGJ. Nadeem et al [40] mentioned that phenolic compounds found in Alternanthera philoxeroides had a negative development effect on the roots and stems of Zea mays seeds and attributed this to ferulic acid, chlorogenic acid, gallic acid, p-coumaric acid, syringic acid, and quercetin. The results of tomato seeds (Figure 7) show that they were slightly more resistant to the BGJ, which could be attributed to natural resistance.…”

In agriculture, weed management is a significant concern because their uncontrolled proliferation decreases soil quality for food crops. Allelopathy is a natural phenomenon in which the activity of allelochemical compounds inhibits the germination and growth of invasive plants as a defense mechanism. Among allelochemicals are polyphenols, which may affect genetic material or crucial enzyme activities for proper physiological function. Agroindustrial residues are a vast source of polyphenolic compounds with allelochemical activity. The bagasse of Agave Lechuguilla, known as guishe, is an abundant residue in México. The guishe has been characterized before by its polyphenolic content. Based on that, a fungal bioconversion process was developed to increase the availability of the allelochemicals in the guishe juice. First, guishe juice was obtained by mechanical pressed and characterized by spectrophotometric analysis. Results showed (g/L): 5.62 flavonoids, 0.64 of hydrolyzable polyphenols, 12.67 of reducing sugars, and 23.3 total sugars. The compounds detected by HPLC-ESI-MS were pterostilbene, hydroxycaffeic, caffeoyltartaric, and 4-O-glucoside coumaric acids, considered allelopathic. After the fungal bioprocess, (+)-gallocatechin and 3,7-Dimethyl quercetin were detected as additional compounds of interest. The flavonoid and hydrolyzable polyphenol content were modified to the highest accumulation of 1.57 and 14.9 g/L at 72 h, meaning a 2.45- and 2.22-fold increase. A bioprocess guishe juice (BGJ) was obtained at the compound accumulation peak of 72 h and evaluated in an allelopathic assay on model seeds (tomato and corn). Results show that BGJ inhibits up to 96.67% of corn seeds and up to 76.6% of tomato seeds compared to positive control.

“…Conversely, Abbas et al [9] observed significant decrease in seedling growth parameters in rice when incorporated with A. philoxeroides residue at different quantities. Nadeem et al [22] observed that soil incorporation of plant residues of A. philoxeroides at various quantities significantly reduced seedling growth parameters of maize, and this reduction was directly proportional to increasing quantities of weed residue. In the current study, incorporation or mulching with A. bettzickiana did not cause reduction in seedling growth which may be attributed to the inefficiency of the compounds released during the decomposition process of incorporated or mulched material to interfere with the growth of the crops.…”

Aims: The aim of the experiment was to investigate the allelopathic potential of Alternanthera bettzickiana (Regel) Voss. Study Design: Experiment on effect of aqueous extract, incorporation and mulching of A. bettzickiana on crop seedling growth was carried out in completely randomized design with five treatments replicated five times. Varying concentrations and time of application of weed extract were also tried in an experiment laid out in factorial completely randomized design with a total of twenty treatment interactions replicated thrice. Place and Duration of Study: Experiments were carried out at Kerala Agricultural University, Thrissur, during 2021- 2022. Methodology: Rice and cowpea were used as test crops in all the experiments. A laboratory study was carried out with test crops sown in petri plates to assess the effect of aqueous extract of the weed at 0%, 2%, 4%, 6% and 8% concentration on germination of the crops. Effect of mulching and incorporation of A. bettzickiana at the rate of 0, 1, 2, 4 and 6 tonnes per hectare on crop growth was studied as pot culture experiments. To assess the influence of time of application of weed extract on seedling growth, extracts at various concentrations of 0%, 2%, 4%, 6% and 8% were applied at 0, 6, 15 and 21 days after sowing of test crops in trays. Results: Only the treatment of 8% aqueous extract of weed caused a significant reduction in seedling vigour of cowpea, while rice was found to be unaffected. Incorporation and mulching of A. bettzickiana showed no significant effect on germination and growth of both the test crops. Time of application of weed extract at various concentrations also had no significant effect on seedling growth of both rice and cowpea Conclusion: Alternanthera bettzickiana possessed no strong allelopathic potential as exhibited by other species of the genera like A. philoxeroides, A. sessilis etc.

“…Weed infestation also exerts negative impacts on economy and causes environmental and health issues in terrestrial ecosystems (Lee et al, 2017) [13] . Maize crop has a specific critical period during which weed control is necessary to reduce yield losses (Nadeem et al, 2019) [14] . Mulching is an important technology widely used in orchards and agricultural system to conserve soil moisture and improve weed control in row crops.…”

Maize (Zea mays L.) called as queen of cereals is the third important cereal crops grown all over the for food and also as cattle and poultry feed. Weeds grow profusely in maize fields in early stages and reduce crop yields drastically. Normally yield loss between 15-30% and in severe cases the yield losses more than 50% is observed in maize. Weeds are one of the main constraints in the crop production and repeated use of synthetic herbicides in heavy doses causes environment pollution which decline in the soil health and increases the number of herbicide resistant weeds. To reduce the chemical effect during consumption and to minimize the weeds through natural way an experiment was carried out with randomized block design with 9 treatments and 3 replications during summer at Maize Research Station, Vagarai. The treatments were T1-Mulching with maize stover (@ 5 tons ha -1 ), T2-Mulching with sugarcane trash (@ 5 tons ha -1 ), T3-Cowpea (1:1 additive series) and incorporation with power weeder on 25-30 DAS, T4-Sunnhemp broadcasting and incorporation with power weeder on 25-30 DAS, T5-Cowpea (1:1 additive series) as brown manuring through targeted application of ITK-based herbicide on 25-30 DAS, T6-Sunnhemp broadcasting as brown manuring through targeted application of ITK-based herbicide on 25-30 DAS, T7-Power weeder twice on 20 and 40 DAS, T8-Hand weeding twice on 20 and 40 DAS and T9-Weedy check. Based on the experimental results, higher grain yield and stover yield, lower weed flora, weed density and total dry matter of weed was observed in mulching with sugarcane trash (@ 5 tons ha -1 ) (T2) followed by hand weeding twice on 20 and 40 DAS (T8). While, the lowest yield and higher weed flora, weed density and total dry matter of weed was recorded in weedy check (T9). In the study it was concluded that the treatment of mulching with sugarcane trash was effective for the control of weeds in maize.
