RICE CULTURE Influence of Row Spacing and Seeding Rate on Grain Yield of Hybrid Rice
Recent interest by producers, researchers, and industry personnel concerning the use of grain drills utilizing 7-in. versus 10-in. row spacing have raised questions as to the optimal drill-row spacing for rice. With the increase in hybrid rice produced and the associated low seeding rates, questions arose regarding the response of these cultivars to row widths. The objective of this study was t...
متن کاملImpact of Rice Nursery Nutrient Management, Seeding Density and Seedling Age on Yield and Yield Attributes
To help farmers in the mid hills of Nepal improve their crop management and rice yields, we conducted a study testing different nursery management options and their effect on grain yield and yield components under rainfed conditions. The experiment was conducted in a farmer’s field during the cropping season 2009 and 2010 at Sundarbazar, Lamjung, Nepal, using a 3-factor factorial RCB design wit...
متن کاملEffect of seeding depth on seedling growth and dry matter partitioning in American ginseng
Greenhouse and field experiments with American ginseng (Panax quinquefolius L.) stratified seed sown at depths of 10 to 100 mm were carried out to determine effects of seeding depth on seedling emergence, growth and development and to calculate optimum seeding depth. The time to 50% seedling emergence (E50) in the field increased linearly from 17 d at 20 mm seeding depth to 42.5 d at 80 mm. See...
متن کاملeffect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Effects of Alternative Seeding Patterns, Seeding Rate, and Seeding Configuration on Yield in a Cotton Production System
With the climbing costs of cotton production, producers must ensure optimal returns on their cotton crops in order to make a profit. The groundwork for a high yielding crop has to start with an accurate and efficient planting system to ensure an optimal stand. However, there are a variety of new systems and techniques to incorporate compared to the conventional system that has been used for so ...
