Twin-row planting in maize (Zea mays L.) has potential for reducing plant-crowding stress optimizing grain yield and resource use. A study was conducted 2020 2021 on a Dundee silt loam the Lower Mississippi Delta (LMD) region of United States to evaluate irrigation water use efficiency (IWUE) single-row (SR) twin-row (TR) patterns with same seed rate under four regimes: rainfed (RF), all-furrow...

to evaluate the yield components, yield and land equivalent ratio affected by relay intercropping of sunflower (helianthus annuus l.) with faba bean (vicia faba l.), a field experiment was arranged based on a randomized complete block design with three replications at the agricultural research station payamenoor university of nagadeh, iran during growing reason of 2012-2013. the treatments incl...

The objective of the study was to evaluate performance a vacuum single-seed planter in field conditions optimize some operating parameters maize production. Three forward speed tractor (4.0, 5.4 and 7.9 km h-1) five target seed spacing (102, 147, 195, 247 309 mm) were evaluated by examining mean spacing, coefficient precision miss index, multiple quality feed sowing depth, deviation from row (i...

greenhouse gases emissions from burning fossil fuels and the effect of these gases on climate change is one of the most important ecological and political issues. in this study the energy consumption and greenhouse gas emissions from tillage and soybean planting were assessed in gorgan. this study is done on 13 soybean farms in 2012. information related to tillage and planting operations were p...

Including food production in non-food systems, such as rubber plantations and biofuel or bioenergy crops, may contribute to household food security. We evaluated the potential for planting rice, mungbean, rice cultivar mixtures, and rice intercropped with mungbean in young rubber plantations in experiments in the Arakan Valley of Mindanao in the Philippines. Rice mixtures consisted of two- or t...

It is uncertain how corn (Zea mays L.) yield would be affected by planting in a twin-row orientation in the southeastern US. The objectives were to compare corn grain yield when: (i) planted in single and twin rows, (ii) plant densities at recommended (1R) and twice the recommended (2R) rate, and (iii) N rates of 168 and 336 kg/ha. Corn was irrigated using a subsurface drip irrigation system. T...

to study the mutual interfering effects between cucumber and celery itercropping, along with the effect of planting density and pattern on yield of cucumber and as well, on celery, an experiment was carried out during 2006 in the horticultural fields of tehran university. the experiment was performed, employing a complete randomized block design of fifteen treatments, each in three replications...
