تحقیق حاضر برای به دست آوردن اطلاعاتی از تأثیر فاصلهی بین ردیفی گیاه Brassica napus L. روی جمعیت شتهها آغاز شد. سه فاصلهی خطی (20، 30 و 40 سانتیمتری)، با فاصلهی ثابت نه سانتیمتر بین هر گیاه، روی آلودگی شته و تأثیرش روی محصول دانه ارزیابی شد. اطلاعات جمعآوری و تصحیح شده روی پارامترهای ثابت نشان داد که افزایش فاصلهی خطها با جمعیت شته رابطهی معکوس دارد. با کاهش فاصلهی داخلی ردیفها، اف...
Cultivation of a second crop in paddy fields of Guilan province is a strategy for optimum use of land, supporting family economy and increasing oil-seed production. However, this is impeded under high rainfall and waterlogging conditions. To enhance second-crop cultivation in paddy fields, surface drainage is inevitable. The surface drainage practices should be performed with minimum costs, l...
Conocarpus erectus L. is a fast growing tree, drought resistant and it is widely planted throughout Saudi Arabia around parking lots and along the streets. It constitutes a renewable resource that could be used as a source of raw materials required for several uses. However, no data were available about its wood quality. This study was established to investigate the effect of plant spacing on s...
C sequencing of higher eukaryotic genomes yielded the surprise that despite hundreds of millions of years of evolutionary separation and strikingly different sizes and body plans, diverse organisms contain nearly the same number of genes! Gene prediction is '30,000 for human (1), slightly lower for other animals (2), including 13,600 for the fruit fly Drosophila melanogaster, 18,400 for the nem...
Nitrogen is the most important nutrient to plant, and its dose depends on amount, availability plant density. This study was conducted in 20 September 2021 end of year, investigate effect nitrogen fertilizer spacing Okra Abelmoschus esculanntus (L.) Moennch vegetative growth pod characters. The treatments were laid out as factorial arrangement a Split Randomized Blocked Design, replicated four ...
The study was taken up to estimate 32 advance breeding lines of rice for grain yield and the related traits in three different planting techniques, viz. direct seeded condition (E-I), transplanting with spacing 15 x cm (E-II) 25 (E-III). experimentation carried out explore parameters hereditary & variability along-with components, extent association indirect special effects components on ri...
this study was conducted to evaluatethe effects of different inter- and intra-row spacing on the dry matter accumulation and partitioning coefficients in faba bean, barakat cultivar. experiment was conducted as factorial in a randomized complete block design with three replications. factors were inter-row spacing (15, 30, 45 and 60 cm) and intra-row spacing (5, 10 and 15 cm). the plant dry matt...
plastic mulches have been used in vegetable production in the most parts of the world. in order to evaluate the performance of the colored plastic mulch and different plant density on cucurbita pepo var. rada, an experiment was conducted in agriculture faculty of ferdowsi university of mashhad during the cultural seasons at 2010. the experiment was arranged in factorial experiment based on rand...
to study the effect of seed density and plant distance on yield and growth parameters of radish, an experiment was conducted in research of station rice at office rasht in 2008-2009. this study was set in secondary culture after rice by factorial experiment with randomized complete block design with 3 replications. treatments consisted of factorial arrangement of three seed density levels (5, 1...
