“…Allam and Galal, (1996); Salehi and Bohrani, (2000); Al-Thabet, (2006) dedicated that decreasing in plant density was led to an increase in head diameter which results are similar with our study. Several studies have reported that with increasing plant density decreases head diameter but increasing plant density enhances the seed yield (Johnson et al 2010;Jahangir et al 2006;Panhwar et al 2017). Modanlo et al (2021) reported that, with increasing plant density yield and oil yield have effected positively but, head diameter, plant height, 100grain yield and grain yield per plant were decreased with increasing plant density.…”

The objective of this study was to determine the effects of plant population per unit area on micro nutrients (Fe, Cu, Zn, Mn, B) uptake of some sunflower genotypes. Three sunflower varieties (Sanay MR, Oliva CL and LG5543 CL) were used as genetic material and three different plant populations: 40800, 57100 and 95200 plants/ha (sowing spacing; 0.35 x 0.70, 0.25 x 0.70 and 0.15 x 0.70 m, respectively). According to the results, the micronutrient concentrations as well as the seed and oil yields and partly also oil content increased significantly as the plant population increased. For all analysed micronutrients, the highest concentration has been obtained with 95200 plant ha-1. Micronutrient elements as well as seed and oil yields differed according to plant density and cultivars. Among the varieties, LG 5543 CL more effected by plant population had the highest micronutrient concentration, seed yield and oil yield. As a result, a high plant population (95,200 plant ha) with the highest micronutrient content and also the highest seed and oil yield could be recommended for Mediterranean environments with a semi-humid climate. However, optimum plant density was found differently according to varieties and years.

A field trial was carried out during 2021/2022 and 2022/2023 seasons at Itay El-Baroud, Research Station, El Behaira Governorate, Field Crop Research Institute, to study the effect of intercropping 25% plant density of sunflower (Sakha 53, Giza 102 and Giza 120) with sugar beet and four treatments of 50% defoliation for sunflower cultivars as follow at flowering stage (L1), 15 days after flowering stage (L2), 30 days after flowering stage (L3) and without defoliation leaves (L4), on sugar beet and sunflower. Results showed that when sowing sunflower Giza 102 with sugar beet in both seasons, yield, its components, and quality of sugar beet recorded the greatest values. The greatest values were obtained for all sugar beetroot character traits during the defoliation treatment (L1) in both seasons. The interaction between sunflower Giza 102 and (L1) produced the highest values for root length, root diameter, and root yield/fed in one season and TSS% in both seasons. The greatest values for all sunflower characters were found in Giza 120. The defoliation treatment (L4) had the greatest values across all sunflower character traits across both seasons. The highest values on sunflower characters were recorded in interactions between Giza 120 and (L4) over both seasons.. The Giza 102 and (L1) defoliation treatments with sugar beetroot plantings in seasons, respectively, produced the greatest LER values (1.23 and 1.31). When sugar beet root and sunflower Giza 102was intercropped with (L1) defoliation treatment in both seasons, the increases in net return were 22855.10 and 27256.59 L.E., respectively.

In Ukraine, a sunflower is the main oil crop from which more than 90% of vegetable fats are produced. An increase in production is due to the expansion of cultivation area, which necessitates research on sunflower hybrids adaptability in the northern regions of Ukraine, where in recent decades, there has been a significant change of weather conditions and which may be favorable for its cultivation. The research was carried out in the Northern part of the Forest-Steppe of Ukraine on light loam chernozems. Reaction to growing conditions of four hybrids was studied by establishing the stability and plasticity of hybrids in terms of yield formation due to changes in morphological characteristics of plants. Yield potential realization is high enough, which is provided by sufficient amounts of positive, active, effective temperatures and precipitation. Calculation of the coefficients of plasticity and stability allows identifying stable sunflower hybrids, hybrids with a high level of plasticity, and recommending them to production. The yield of early-maturing hybrid Ukrainskyi F1 increases rectilinearly with plant density increasing (r = 0.977 -0.998), while hybrids P63LL06 (r = 0.651 -0.882); NK Ferti (r = 0.589 -0.846), and NK Brio (r = 0.689 -0.804) form a higher yield at standing densities up to 60 thousand plants per hectare, and with further thickening, the yield decreases. With the thickening of sowings, the height of all hybrids plants increases (r = 0.97 -0.99), and there is a decrease in the number of seeds per anthode, and the weight of 1000 seeds. Sunflower hybrids can be divided into the groups according to the peculiarities of yield formation due to morphological features: 1) yield increases only due to sowings' thickening-Ukrainskyi F1; 2) combined efficiency-increasing sowings' density to 60 thousand plants/ha and generative organs formation-NCKBrio; 3
