This study was carried out in Kahramanmaras ecological condition in 1994 and 1995. In this study peanut cv "Bocaunba" and peanut line "PI 260690" were planted at 60, 70 and 80 cm row spacies and 15, ...
Response of Popcorn（Zea mays everta）to Nitrogen Rates and Plant Densities
Popcorn（Zea mays everta） Nitrogen Rates Plant Densities
2009/1/14
The objective of this study was to evaluate grain yield and yield components of popcorn with different nitrogen rates and plant densities. Field studies were conducted in 1995 and 1996 at Kazova Plain...
Effects of Increased Phosphorus Rates and Plant Densities on Yield and Yield-Related Traits of Narbon Vetch Lines
Above ground biomass dry matter narbon vetch phosphorus rate plant density
2009/1/9
We evaluated seed yield, forage yield, and yield-related traits of 4 different narbon vetch (Vicia narbonensis L.) lines using 3 phosphorus rates and 4 plant densities. The experiment was conducted du...
Evaluation of a Production System in China that Uses Reduced Plant Densities and Retention of Vegetation Branches
Production System Uses Reduced Plant Densities Retention Vegetation Branches
2008/12/10
In China, a cultivation system that uses low plant densities and the retention of vegetative branches is currently referred to as the cost-saving cotton production system, which contrasts with the con...
