Rapeseed (Brassica napus L.) is an important alternate oilseed crop in eastern Anatolia, Turkey. No information on plant density for rapeseed is available in this region. Therefore a study was initiated to investigate the effects of spacings between rows and spacings within rows on the yield and agronomic characteristics of two genotypes of spring rapeseed (Tower and Lirawell) in Erzurum, easte...

Abstract In the Republic of Uzbekistan, cotton cultivation is carried out on row spacings 60; 76 and 90 cm. The machine-tractor parks cotton-growing farms are equipped with agricultural machines designed for these inter-row they aggregated by tractors gauges them. Such a variety tractor creates problem mismatch between gauge spacing when moving from one to another, increases spare parts narrows...

Research results at other locations in western U.S. indicate that a plant spacing of approximately 12 inches within rows and 20 or 22 inches between rows is necessary to obtain near maximum yields of sugarbeets (Beta vulgaris 1..) and yet maintain adequate space for machinery operation (4, 6, 10). 3 Increasing row and plant spacings with corresponding decreases in plant population have reduced ...

Abstract—Gladiolus is an important cash crop and is grown mainly for its elegant spikes. Traditionally the gladiolus corms are planted manually which is very tedious, time consuming and labor intensive operation. So far, there is no planter available for planting of gladiolus corms. With a view to mechanize the planting operation of this horticultural crop, a prototype of 4-row gladiolus plante...

Cultural management practices that reduce the off-site transport of herbicides applied to row crops are needed to protect surface water quality. A soybean [Glycine max (L.) Merr.] field study was conducted near Stoneville, MS on Sharkey clay to evaluate row spacing (50 cm vs. 100 cm) effects on metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(methoxy-1-methylethyl) acetamide] transport. One ...

Optimizing row spacing can potentially improve yields when resources such as light and water are limited. Sugarcane in Louisiana is principally grown on rows spaced 1.8 m apart, but interest planting 2.4 increasing. In this study, we hypothesized that wider would have greater availability. Soil moisture sensors were placed at 15, 30, 45 cm depths treatments: spacings, two varieties (L 01-299 Ho...
