“…Especially, in stress condition the lower (old) bolls fully open while young bolls at the top part of the plant remain unopened and poor in quality. This is in line with (Siddiqui et al, 2007) who reported that the number of unopened balls increased linearly as the intra-row spacing increased. Regarding the total bolls, higher values were scored in the wider space area (90x25 cm, 80 × 25 cm and 70 × 25 cm) (Table 3).…”

The yield f cotton (Gossypium hirsutum L.) in Tigray is very low because of the lack of improved agronomic practices. Cotton producing farmers (if in row) adopt 90 × 20 cm. However, it is too wide for rain-fed cotton, which means more empty space left in-between the rows, which affect the yield negatively. Objective of this study was to estimate the optimum inter-row and intra-row spacing of cotton under rain fed condition. The experiment was laid out in split-plot design having three replications. The different levels of inter-and intra-row spacing have affected the agronomic traits and the seed cotton yield significantly. The narrow inter row and closer intra row have a higher plant population. The 90 cm inter row have taller (~90 cm) plant than the 60 cm inter row. The wider intra row (25 cm) scored higher (11-13) opened bolls in all the inter rows. The wider plant geometry recorded a higher number of unopened bolls (6). Heavier bolls (11 g) were recorded on the narrow inter-row spacing under all levels of intra-row spacing. Lighter boll weight was in 90 cm row spacing irrespective of the intra rows. Normally, boll weight was reduced as the inter-row spacing increased. Maximum seed cotton yield was recorded on 60 × 10 cm. Lower seed cotton yield was found on 90 × 25 cm. Generally, seed cotton yield was reduced as inter-and intra-row spacing increased. Therefore, the 60 × 10 cm inter and intra row should be recommended for maximum seed cotton yield under rain fed condition.

“…Moreover, as compared to CF treatments, greatest yields were achieved with organic matter treatments ( Kayikcioglu et al, 2019 ). Greater seed cotton yields of the present study than the previous ones were attributed to differences in plant density ( Siddiqui et al, 2007 ). Iqbal and Khan (2011) reported that seed cotton yields differed significantly among different plant spacing and genotypes.…”

“…We suppose that the climate and environmental conditions may be effective in ginning out turns. Additionally, the lint and seed cotton yield were affected significantly by the plant spacing and varieties ( Siddiqui et al, 2007 ). Cottonseed quality is also determined by its content of mineral and non-mineral nutrients such as N, C, S, K, Ca, Zn, and Fe because of their direct or indirect contribution to biosynthesis in plants such as protein (e.g.…”

Treated municipal sewage sludge (TSS) was applied to the cotton plant at rates of 10, 20 and 30 t/ha per year. Seed cotton yield (71.4%), lint yield (67.7%) and cottonseed yield (74.1%) were increased significantly when sludge was applied at a rate of 30 t/ha (TSS3). The effects of TSS applications on seed yield, lint yield and cottonseed yield were listed as TSS3 > TSS2 > CF > TSS1 > C according to the applications. The increasing TSS levels had a positive effect and increased the total N concentration compared to the control. The highest N value was observed in TSS3 plots, while the lowest value was recorded in control (C) plots. The highest P value was found in control (C) at 0.80% and in 10 t/ha (TSS1) at 0.80%, while the lowest value was found in the TSS2 application (0.70%). The K concentration of cottonseed increased with the increasing TSS rates, from 1.56% in control plots to 2.20% in 20 t/ha application (TSS2). Corresponding to the TSS levels, the calcium of plant tissues was determined by a range of 0.12–0.13%. The treatments of TSS and mineral fertilizer had similar effects on the Mg content of cottonseed, which was in the range of 0.38–0.43%. Na content in plant tissue increased with increasing dose of sludge application compared to control soils. Increasing doses of TSS had no significant effect on the concentrations of iron (Fe), copper (Cu), zinc (Zn), manganese (Mn) and boron (B) in cottonseed. The order of the elements with respect to their amounts in cottonseed was as follows: Fe > Zn > Na > B > Mn > Cu. The concentrations of non-essential elements (Ni, Cd, Cr, Pb, Hg and As) in cottonseed were below the permissible limits.

A field experiment was conducted at the Experimental Farm, Faculty of Agriculture, Menoufia University, Shebin El-Kom, Egypt during 2019 and 2020 seasons to study the effect of plant distribution patterns i.e. D1 (sowing cotton in furrows 70 cm width in one ridge with 25 cm between hills and two plants/hill), D2 (sowing cotton in furrows 70 cm width in one ridge with 12.5 cm between hills and one plant/hill), D3 (sowing cotton in beds 140 cm width in two ridges with 25 cm between hills and two plants/hill), D4 (sowing cotton in beds 140 cm width in two ridges with 12.5 cm between hills and one plant/hill) and foliar application with plant growth regulators i.e. control, kinetin (15 ppm), naphthalene acetic acid (15 ppm), mepiquat chloride (100 ppm), mepiquat chloride + kinetin and mepiquat chloride + naphthalene acetic acid at 80 and 95 DAS and on light intensity, morphological traits, flowering and abscission, yield and its components and seed and fiber quality of Egyptian cotton (Giza 86 cv.). The results indicated that sowing cotton plants with D3 pattern surpassed the other plant distribution patterns in most studied characters, while D1 increased plant height but decreased fiber fineness. On the other hand, number of squares/plant, boll weight, 100-seed weight, fiber strength and uniformity index were not significantly affected by plant distribution patterns. Application of growth regulators either single or dual caused a positive effect. NAA or MC+NAA were the superior treatments in most characters studied. However, unsprayed cotton plants increased total abscission. It could be concluded that sowing plants in beds with plant distribution pattern (D3) and foliar application with 100 ppm MC at 80 DAS followed by 15 ppm NAA at 95 DAS was the best interaction treatment in comparison to other interaction treatments to obtain the highest values of light intensity, total dry weight/plant, number of open bolls / plant, seed cotton yield per plant and fed, oil yield /fed and protein yield /fed).
