For evaluation of the effects of super absorbent polymer under different irrigation regimes on the yield and yield components of Brassica napus L., a factorial experiment was carried out, based on randomized complete block design with four replicas. Treatments included super absorbent polymer (0, 1, 2, 3, 4 and 5 g/kg soil) and induced drought stress (irrigation at 25, 50 and 75 mm evaporation from class A pan). The experiment was conducted in pots with 5 kg of soil. Data analysis of variance showed the significant interaction effect between polymer and irrigation on the stem length, width and weight, the number of seeds per sheath, number of seeds per plant, the number of sterile and fertile sheath per plant, fertile sheath percentage (fertile sheath/ total sheath ×100), 1000 seeds weight, seed weight per plant, sheath weight per plant and the number of total sheath. The present study revealed that indifferent from the applied amounts of the super absorbent polymer, in all cases the measured characters have been more affected by induced drought stress.

Abstract Corn is one of the most important cereal crop grown in Iran. A complete randomized design with four replications was used to analysis the influence of soil amendment of super absorbent polymer on grain yield and yield components of corn in center of Iran in 2016 and 2017. Treatments with super absorbent polymer were 0 kg/ha (S1), 15 kg/ha (S2), 30 kg/ha (S3), and treatments with fertilizers were 50% (F1), 75% (F2), 100% (F3), which could be combined into nine pots. The influence of super absorbent polymer was significant on spike weight in 2017, above-ground biomass in 2016, one hundred seed weight in 2016, and grain yield in 2017. There was no meaningful influence of super absorbent polymer on spike weight in 2016, above-ground biomass in 2017, 100 seed weight in 2017 and grain yield in 2016. Fertilizer treatments had significant influence on spike weight, above-ground biomass, 100 seed weight, and grain yield in both 2016 and 2017. The interaction between SAP and fertilizers had significant effect on above ground biomass in 2017. In both years, the highest spike weight, above ground biomass, 100 seed weight and grain yield was related to S3 (30 kg/ha), followed by S2 (15 kg/ha) and S1 (0 kg/ha), respectively. 100% application of fertilizer (F3) had obtained the maximum spike weight, above ground biomass, 100 seed weight and grain in both 2016 and 2017. Our data have shown that the applied SAP had a remarkable effect on corn growth and yield under different fertilization treatments, and its application of 30 kg/ha gave the best corn production index.

Yield And Yield Components

The effects of time of leaf removal on Brassica napus L. were studied under field conditions at Saskatoon in 1976 and at Swift Current in 1977. Leaf removal at the start of flowering reduced the number of pods per plant, increased seed weight, and reduced seed yield. Leaf removal at the end of flowering did not affect yield or its components.

Rapeseed (Brassica napus L.) is an important alternate oilseed crop in eastern Anatolia, Turkey. No information on plant density for rapeseed is available in this region. Therefore a study was initiated to investigate the effects of spacings between rows and spacings within rows on the yield and agronomic characteristics of two genotypes of spring rapeseed (Tower and Lirawell) in Erzurum, eastern Anatolia, during 1994 and 1995. The effects of spacings between or within rows on the yield and yield components of Tower and Lirawell, two cultivars of Brassica napus L., were studied for 2 years inErzurum,Turkey. Rows were spaced at 15, 30 and45 cm. Spacings within rows were 5, 10 and15 cm. The results of this study suggested that seed yield was significantly affected by spacings between rows but not by spacings within rows, and that rape yields were higher at the narrow (15 cm) row spacing compared to the middle (30 cm) and wider (45 cm) spacings.
