In order to study the effect of cold stress in flowering stage on yield and yield components of different rice cultivars, an experiment was performed as split plot factorial based on completely randomized design (CRD) in greenhouse of deputy of rice research institute of Iran (Amol) in 2010, in three repetitions. Treatment included 5 varieties as main factors that included cultivars of shirudi, fajr, local tarom, hybrid, and line 843. Two levels of temperaturesT1(13°C, stress temperature) andT2(32°C, normal temperature, control) along with flowering stage were selected as two subfactors. Three seedlings were planted in each plot. The cold stress was done in flowering stage with holding pots at 13°C for 15 days. Results showed that low temperature had significant effect in level of 1 percent on all characters, such as the number of panicles, the length of panicle, and the number of full, empty, and total grains; as a result, yield had caused significant reduction. Interaction between temperature and varieties showed that most tolerant variety in relation to temperature stress along with least percentage yield (19%) is shirudi variety and the most sensitive one with most percentage of yield decrease (29%) was local tarom variety.

An experiment was conducted to evaluate effect of urea fertilizer on yield and yield components of Zea mays L. Using Randomized Complete Block Design (RCBD) split plots in three replications in agricultural research farm of Balkh University by 2019. Doses of urea used in this experiment were 0, 80, 160 and 240 kg ha-1 , respectively. It has been found that amount of nitrogen fertilizer (urea) had significant effect on yield of maize at p<0.05. The higher level of nitrogen caused the higher grain yield, number of kernels per ear, the number of grains per ear row, ear diameter, cob length, grain per plant and plant height. As a result 7.76 ton ha-1 was recorded as high yield while 240 kg ha-1 urea was used, and 5.12 ton ha-1 was recorded as low yield in treatment one with 0 kg ha-1 of nitrogen fertilizer. Finally, as a result using 240 kg ha-1 nitrogen fertilizer is recommended.

ABSTRACT There is a lack of researches that evaluate the development and nutrient accumulation in super early genotypes of common bean for the elaboration of fertilization programs. This study aimed at characterizing the development; N, P, K, Ca and Mg accumulation by leaves; grain yield; and yield components of super early genotypes of common bean. Field experiments were conducted in a randomized blocks design, with four replications. The treatments consisted of the IPR Colibri (control), CNFC 15873, CNFC 15874 and CNFC 15875 genotypes. Plants were sampled throughout the common bean development, being divided into leaves, stems and pods. After determining the dry matter, the contents of N, P, K, Ca and Mg accumulated in leaves were estimated. At harvesting, the grain yield and yield components were evaluated. The biomass accumulation in stems and leaves occurred until the flowering stage, and then it started in the pods until harvesting. The genotypes that absorbed more nitrogen and phosphorus had a higher grain yield. The average growing season of super early genotypes was 70 days (winter) and 63 days (summer). CNFC 15874 was the most productive genotype in the winter, with grain yield similar to the IPR Colibri cultivar (control). In the summer, CNFC 15873 and CNFC 15875 achieved grain yield similar to the IPR Colibri cultivar.

Due to the high genetic potential for yield and favourable nutritional value, triticale is a promising plant species. For achieving high and stable yields, it is necessary to have favorable agroclimatic conditions of the locality, variety and advanced agricultural techniques, with special emphasis on fertilizing. This study examines the effect of increasing rates of nitrogen on yield and yield components of five cultivars of winter triticale: Odisej, Kg-20, Triumph, Rtanj and Tango. The three-year trial (2009-2012), which was set up in a randomized block system with three replications, included control and three different doses of nitrogen fertilization (0, 60, 90 and 120 kg ha-1). In all variants of fertilization, 80 kg ha-1 P2O5 and K2O were added beside nitrogen. The obtained results showed that the use of nitrogen had a positive effect on yield and yield components in all variants and in all cultivars. The variety Tango had the highest average grain yield, while the variety Kg-20 had the lowest. Also, Tango had the highest value of the 1000 grain mass and the number of grains per spike, while Triumph had the highest value of hectoliter weight. The application of fertilizers led to a very large and significant increase of yield compared with the control. Accordingly, all studied cultivars had the highest yield with the highest quantities of nitrogen (120 kg ha-1). Considering that triticale is intended mainly for feeding livestock, the results of these studies would be valuable in terms of its growing as a forage crop as well as in terms of its breeding for grain quality and productivity.
