Journal ArticleDOI
TL;DR: In this article, the authors present data of two years field experimentation on yield and yield components of a wheat-maize intercrop system in different planting configurations in the Netherlands and show that there is a potential yield benefit for the wheat and maize intercropping system under Western European growing conditions.

TL;DR: There were differences both in the times of year at which seedlings emerged and in the extent to which seeds survived in cultivated soil among ten species of Umbelliferae, including Sison amomum, Conium maculatum and Torilis japonica.
Abstract: (1) Among ten species of Umbelliferae there were differences both in the times of year at which seedlings emerged and in the extent to which seeds survived in cultivated soil. (2) The main time of emergence of Smyrnium olusatrum was in the autumn of sowing, while that of Anthriscus sylvestris, Heracleum sphondylium, Angelica sylvestris, Conopodium majus and Pastinaca sativa was in the following spring. Few viable seeds of these species remained after a year. (3) Seeds of Sison amomum, Conium maculatum and Torilis japonica survived for longer. Sison amomum had autumn and spring peaks of emergence, while Conium maculatum and Torilis japonica were mainly spring-germinating. (4) Maximum emergence of the spring-germinating annual weed Aethusa cynapium occurred in the second or third year, and about one-fifth of the seeds were still viable and dormant after 5 years.

TL;DR: A greater occupation of soil by the cultivated species, greater yield forage and greater amount of nutrients incorporated of this biomass were observed, without significantly affecting maize yield grain.
Abstract: The aim of this study was to evaluate the occurrence of weeds, nutritional state and yield of maize - B. brizantha intercrop under different layouts of Brachiaria pasture sowing treated with the herbicide mixture nicosulfuron + atrazine and atrazine. In the plots, the treatments consisted in maize and B. brizantha sowing in single crops, besides four forms of establishing B. brizantha by sowing one and two rows of B. brizantha in-between the maize rows; sowing along the same row as maize; and sowing the forage scattered in-between the maize rows. In the subplots, the two secondary treatments consisted in using the herbicide mixture nicosulfuron + atrazine (8 + 1,500 g ha-1) and atrazine (1,500 g ha-1) applied 30 days after emergence (DAE). Dry biomass of the macronutrient levels, grain yield and the weight of a thousand maize kernels, as well as the total dry matter yield and macronutrients accumulated by the pasture were evaluated. The weed species Brachiaria plantaginea, Brachiaria decumbens, and Sorghum arundinaceum were controlled by the mixture nicosulfuron + atrazine; the species Digitaria horizontalis, Cyperus rotundus, and Artemisia verlotorum were not controlled by the herbicide mixture. Lower levels of total chlorophyll and N leaf contents in maize were observed when two rows of B. brizantha were cultivated in-between the maize rows. When the herbicide mixture nicosulfuron + atrazine was used, highest levels of total chlorophyll, N, P, and K, grain yield, and weight of a thousand kernels were observed in maize compared to the treatments without product application. When two rows of B. brizantha were cultivated in-between the maize rows, a greater occupation of soil by the cultivated species, greater yield forage and greater amount of nutrients incorporated of this biomass were observed, without significantly affecting maize yield grain.

TL;DR: The negative effect of wheat stubble on cotton stand establishment can apparently be overcome by; limiting the amount of aboveground residues that ara incorporated into the seedbed during planting, increasing the seeding rates, and planting tolerant cultivars.
Abstract: Emergence was reduced by an average of 9% for Paymaster 404 and 21% for Acala A246 when wheat stubble residues were present in the seedbed. The allelopathic effect of wheat stubble indirectly influenced lint yield by affecting population densities. The negative effect of wheat stubble on cotton stand establishment can apparently be overcome by; limiting the amount of aboveground residues that ara incorporated into the seedbed during planting, increasing the seeding rates, and planting tolerant cultivars

Journal ArticleDOI
TL;DR: It was concluded that weeds could be controlled effectively by sowing cover crops after planting main crops in organic farming systems in a snowy-cold region and this growth inhibition was alleviated when cover crops were sown after the establishment of main crops.
