The effect of early weed competition was determined for a maize (Zea mays) crop grown in Waikato Maize was established in three different environments viz weedy (no herbicide) grass weeds (preemergence atrazine) and broadleaf weeds (preemergence metolachlor) Surviving weeds were controlled with postemergence nicosulfuron (60 g/ha) after different periods of competition and the plots kept weed free for the remainder of the trial Weeds left completely uncontrolled for 4 weeks after emergence significantly reduced crop yields When a preemergence herbicide was used surviving weeds began to reduce

Sifting to conservation tillage from conventional one makes weeds control more difficult due to the absence of tillage. In the longer term, conservation tillage may alter the floristic composition of weeds in the soil seedbank. The nature of weed seedbank changes over time in intensively cropped rice-based rotations in Bangladesh is not well understood. Two long-term experiments (at Rajshahi and Rajbari) were sampled at 0-15 cm soil depth to study the effects of strip tillage (ST) and bed planting (BP) at both sites and Zero tillage (ZT) at Rajbari plus retention of residues of previous crops

Abstract To determine the Critical Period for Weed Competition in Sesame crop and predict the total yield losses by weed competition, a field experiment was conducted during season 2023 using three sesame varieties which were Wadaa, Rafidain, and Had by making the field free of weeds by hand for periods of 1, 2, 3, 4, 5 weeks beginning from crop emergence. Then, allowed weeds to grow after these periods until the end of the growing season. Results of the study determined this period by making the field free of weeds for three weeks after emergence depending on acceptable yield losses of 10-12%

In this study, we compared weed assemblages of several hedgerow types and herbaceous field margins. Ranking that takes into consideration weed abundance was clearly demonstrated: planted hedgerows > herbaceous field margins > natural woody hedgerows.

The cohabitation of weeds with crops may not always pose problems. Weeds are plant pests that negatively impact crop yield. However, it is essential to determine when pest status is reached in crops for weed management decisions in crop production. Field experiments were conducted during the rainy seasons of 2017 and 2018 at the research farm of the Institute of Agricultural Research and Training Ibadan (7o38' N 3o 84' E), located in the rainforest-savanna transition agroecology of southwestern Nigeria.

Nutrient status of young pecan [Carya illinoensis (Wangenh.) C. Koch] trees grown under eight combinations of orchard floor management and irrigation was determined by leaf and soil analyses. Orchard floor management practices were weedy-unmowed, weedy-mowed, weed control with herbicides, and weed control by disking, with trees either irrigated or nonirrigated. The element most affected by treatment was K. Mean leaf K for the two sample years was significantly (P < 0.01) lower in the weedy plots (0.56% K) than in those where weeds were controlled (0.76% K), suggesting a highly competitive e

Abstract The present work aimed to estimate the optimum period for weed control and predict yield losses coming from weed competition of three Sesame varieties under various weed removal periods. A field experiment was conducted during the season of 2023 by making the study field free of weeds by hand weeding starting from sesame plant emergence until periods of 1, 2, 3, 4, and 5 weeks. Then, weed plants are allowed to grow after these periods till the end of the growing season. Results of the study determined that the optimum period for wee control from the sesame plants’ emergence until the

The purpose of our research was to assess the impact of modern herbicides on the infestation (clogging) of tomato seedlings with annual weeds and the productivity of cultivated plants in the natural and climatic conditions of the Republic of Kalmykia. It was revealed that the main weeds of tomato plantings for all the years of research from annual dicotyledonous species were-white mar, bindweed buckwheat, bird mountaineer, southern salt grass; less

The world population will rise in future, which would demand more wheat production to fulfil dietary needs of wheat-dependent population of the world. Food security in wheat-dependent regions will greatly rely on wheat productivity. Weed infestation is a major constraint reducing wheat productivity globally. Nonetheless, cropping systems and weed management strategies strongly influence weed infestation in modern agriculture. Herbicides are the key weed management tool in conventional agriculture. However, frequent use of herbicides have resulted in the evolution of herbicide-resistance weeds,

Weed management is an ongoing constraint in southern Africa for conventional farming systems and in emerging conservation agriculture systems, which are more heavily reliant on herbicides for primary weed control. The challenge of rising labour costs and decreasing availability creates a greater need to develop effective and efficient weed management methods in key crops such as maize. Field experiments were conducted at Sebele Agricultural Research Station, Botswana in the 2011/12 and 2012/13 cropping seasons to evaluate pre-emergence application of atrazine at 1,000 and 2,000 g a.i. ha-1 and
