ABSTRACT-In conventional agriculture, a large amount of energy is consumed in fuel consumption and depreciation of farm tractors and any other farm equipment mostly in tillage and planting operations. The main purpose of this research was to evaluate a till-planting unit equipped with three jointers. This unit was expected to act as conventional furrow openers such as shovel openers tilling the...

In this experimental work, we have shown that the geometric shape of the grooves (furrows) plays an important role in sediment dynamics. In addition, the rheological behaviour of solid discharge does not depend only on the velocity discharge but also on the geometric shape. Keywords—Laboratory experiments, soil erosion, groove, furrow, sediment transport

Furrow formation is one of the most labor-intensive operations in potato cultivation technology. The article discusses justification and determination furrower parameters planter. Analytical dependences height junction point disks width furrow bottom are obtained, taking into account technological parameters, its design features physical mechanical properties soil. Potatoes planted usual way. m...

The Northeast China (NEC) was the most important agriculture areas and known as the Golden-Maize-Belt. Based on observed crop data and crop model, we design four simulating experiments and separate relative impacts and contribution under climate change, planting date shift, and varieties change as well change of varieties and planting date. Without planting date and varieties change, maize yiel...

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...

this experiment was performed based on split plot in rcbd with three replications in minab agricultural research station during two successive years. main plots were allocated to planting method (basin and furrow) and sub plot to four onion cultivars (‘primavera’, ‘white early grano 502’, ‘ht3544’ and ‘ht3560’). nursering was done in october and the transplants were transferred to main land in ...

Abstract The objective of this work was to evaluate sugarcane (Saccharum spp.) yield in response corrective and maintenance phosphorus fertilization Oxisols. Two experiments were carried out randomized complete blocks with four replicates. In the treatments, 150 kg ha-1 P2O5 broadcast incorporated before planting. 40 per year applied over trash blanket. All except control, fertilized 170 planti...
