this study was conducted in split plot design based on a randomized complete block design in naghadeh region, urmia, iran in 2009-10. two sowing patterns including a1) single row planting with 50 cm between-row spacing, and a2) two rows planting on the hill with 40 cm distance and 50 cm between-row spacing (40×50) were allocated to main plots and four furrow compactions including b1) control, b...

ett, 1999), planted early and at low populations; thus, relying on the sorghum hybrid to adapt to the growing Typical planting recommendations for dryland grain sorghum [Sorconditions by tillering. Research by Jones and Johnson ghum bicolor (L.) Moench] in the southern High Plains are to delay (1991, 1997) demonstrated that the optimum planting date, until soil water is adequate for crop establ...

The use of water resources should be restricted until a suitable irrigation and planting system is developed in the North China Plain. This study was aimed to study the effects of planting pattern and irrigation on the farmland microclimate, and indentify possible ways to improve the yield of winter wheat. The field experiments in a randomized complete block design with four replicates were con...

The objective of this study was to determine if planting cotton into the space between the previous year's rows reduces crop loss due to Meloidogyne incognita compared to planting in the same row every year. Row placement had a significant (P </= 0.05) effect on nematode population levels only on 8 July 2005. Plots receiving 1,3-dichloropropene plus aldicarb had lower nematode population levels...

The basic requirements for small scale cropping machines are, they should be suitable for small farms, simple in design and technology and versatile for use in different farm operations. A manually operated template row planter was designed and developed to improve planting efficiency and reduce drudgery involved in manual planting method. Seed planting is also possible for different size of se...

A literature study was undertaken on the weeding of maize on smallholder farms in Ciskei, South Africa. Most weeding under these conditions is carried out by hand pulling or hand hoeing. Only limited use is made of animal traction, and large-scale development of this method will not be possible until the conventional broadcast method of planting maize has been replaced by row planting.

abstract in order to study the effect of planting season (autumn and spring) and plant density on growth traits and flower yield (dry weight of flower) of matricaria (matricaria chamomilla), an experiment was carried out at the research field of agricultural faculty of shirvan, affiliated to ferdowsi university of mashhad. a split plot design with two factors, including planting time and plant ...

Intercropping systems compared to monoculture systems can more efficiently use the existing resources which ultimately will lead to increased plant performance. Therefore, to evaluate the benefits of intercropping maize and beans and assess its impact on yield and yield’s component, an experiment was conducted in factorial design with randomized complete block design in three replication, in 20...
