in order to study the effect of harvesting time on yield of rapeseed cultivars, this research work was carried out at paddy fields of rice research institute of iran in rasht andamol during 2005-2006 and 2006-2007 cropping seasons. the experiment was conducted in a split plot based on randomized complete block design with three replications. four rapeseed cultivars including hyola 308, hyola 40...

In order to investigate the effect of planting method and sugarcane residue compost fertilizer on morphological and physiological traits and grain yield of corn, a field experiment using a split-plot arrangement was accomplished in a randomized complete block design with four replicates in Mian-Ab, Shooshtar, south-west Iran in summer 2018. Experimental factors included four planting methods (o...

  Using growing degree days (GDD) for expression of duration of plants’ developmental stages is preferred over calendar time. Therefore, determination of GDD and zoning of regions is very important for on time and correct agronomic practices and also for better land use. To determine the required GDD for developmental stages of spring safflower cultivars, the data obtained from planting-date ex...

We tested the hypothesis that a high-fat diet (75% fat; 5% carbohydrates; 20% protein), for which 15% of the fat content was substituted with n-3 fatty acids, would not exhibit the diet-induced increase in pyruvate dehydrogenase kinase (PDK) activity, which is normally observed in human skeletal muscle. The fat content was the same in both the regular high-fat diet (HF) and in the n-3-substitut...

In terms of tillering potential, the aboveground portions of rice are significantly influenced by the nitrogen level (NL) and transplant density (TD). To obtain a suitable combination of NL and TD, five NLs (0, 90, 180, 270 and 360 kg ha-1) and two TDs [high density (HD), 32.5×104 hills ha-1; low density (LD), 25.5×104 hills ha-1] were used in the rice experiments during 2012 to 2014, in Jiangs...

Controlled release urea (CRU) has been widely adopted to increase nitrogen (N) use efficiency and maize production, but the impacts can range widely depending on water availability in the soil. In an experiment using Zhengdan 958 (a popular summer maize hybrid), three levels of water treatments (adequate water condition [W3], which maintained soil moisture at about 75% ± 5% of the soil's field ...

Effects of NPK 15:15:15 compound fertilizer and planting season on flowering and sex expression of pumpkin were analyzed at the Teaching and Research Farm, Obafemi Awolowo University, Ile-Ife, Nigeria in year 2010. Results deciphered that day to 50% flowering, number of male and female flowers responded to season than fertilizer rates. Late season planting reached 50% flowering 5 days earlier t...
