“…Maheswari et al (2019) reported that when plant growth retardants are applied to plants, internodes become shorter and leaves become thicker and greener, alters plant morphology and can alter assimilate partitioning in favor of plant growth by increasing radiation utilization efficiency and also increases net photosynthesis. These results are in agreement with those found by Sabale et al (2017) and El-Shazly (2020).…”

“…Mao et al (2015) observed that, dry and warm season aided the mepiquat chloride in increasing the boll retention and lint yield during the late boll maturation phase. Sabale et al (2017) showed that, the applied 200 ppm mepiquat chloride increased number of flowers and flower retention percentage, whereas decreased abscission. El-Shazly (2020) reported that the highest number of total flowers plant -1 resulted from foliar spraying with Pix as compared with the control.…”

A field experiment was carried out at El-Gemmeiza Agricultural Research Station, El-Gharbia Governorate, Egypt in 2018 season and repeated in 2019 season, to assess the effects of transplanting cotton seedlings of 4 weeks old with their complete root system compared with early and late direct seeding with or without Pix treatments on cotton Giza 86 cultivar productivity. A strip-plot design with four replicates was used. The obtained results indicated that planting with transplanting or early direct seeding significantly increased sympodia, monopodia, earliness attributes, yield components and uniformity index in both seasons, except plant height, internode length, shedding% and first sympodium node which were decreased. Early direct seeding and transplanted cotton significantly increased seed cotton yield fed -1 by 16.53 and 11.82%; 17.54 and 12.99% as compared to late direct seeding in the first and second seasons, respectively. Application of Pix at the two levels examined (2.5 cm 3 /L and 5 cm 3 /L) significantly decreased growth traits, whereas significantly increased earliness attributes, seed cotton yield, yield components and uniformity index in both seasons, as well as seed index, fiber length and strength in one season only, except days to first flower and shedding% in both seasons which were decreased, whereas first sympodium node did not affected. It could be concluded that early sowing or transplanting seedlings of 4 weeks old and sprayed with Pix three times at the low level (2.5 cm 3 /L) gave high productivity. That is recommended to overcome the delay of planting and its negative impact under conditions similar to El-Gemmeiza location.

“…In addition, MC is an anti-gibberellin that inhibits the production of gibberellins in the plants which normally would enlarge the plants cells by blocking the cyclization of geranylgeranyl pyrophosphate to capatyl pyrophosphate and also blocks further trans of capatyl pyrophosphate to ent-kaurene in the gibberellic acid biosynthesis pathway. Similar results were obtained by other investigators who found that foliar application of growth regulators such as kinetin at a rate of 20 ppm (Kassem et al, 2009), NAA at a rate of 30 ppm (Kataria andKhanpara, 2011 andSabale et al, 2017) significantly increased plant height compared to untreated plants. However, Priyanka and Dalvi (2019) reported that application of MC decreased plant height.…”

“…In this respect, leaf area/plant was increased by the application of NAA at rate of 0.045g/100 L (Parveen et al, 2017). Chlorophyll content was significantly increased by foliar application of growth regulators such as NAA (Parveen et al, 2017), MC (Sabale et al 2017) and kinetin (Kassem et al, 2009) compared to untreated cotton plants. Moreover, Sarlach and Sharma (2012) stated that application of NAA at rate of 20 µg/ml increased stem, leaves and total dry weights/plant compared to untreated plants.…”

“…Moreover, number of bolls/plant was increased by the application of NAA (Parveen et al, 2017) and MC (Priyanka andDalvi., 2019 andHussain et al, 2021). On the other hand, many investigators found that abscission percentage could be decreased by foliar application of NAA at rate of 30 ppm (Sabale et al, 2017 andGeethanjali et al, 2018). Also, abscission % was decreased by the application of MC (300 ppm), NAA (50 ppm) and kinetin (50 ppm) in comparison with the control treatment as reported by Deol et al (2018).…”

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).

Combined effects of organic amendments and fertilization on cotton growth and yield

With escalating fertilizer prices, interest in using poultry litter as a source of plant nutrients has increased. However, the rapid decomposition of litter, particularly in the hot and humid southern United States, makes poultry litter vulnerable to loss of nutrients. Biochar and lignite have been proposed to mitigate nutrient loss, particularly N. However, information on the integration of biochar and lignite with poultry litter on cotton (Gossypium hirsutum L.) growth and yield is limited under southeastern agro-ecosystems. A field experiment was conducted on a Leeper silty clay loam soil from 2017 to 2020 to evaluate the combined effect of poultry litter and inorganic N fertilizer with biochar and lignite on cotton growth, yield, and nutrient utilization. The treatments consisted of a 3 × 3 full-factorial arrangement of amendments and fertilization types organized in a randomized complete block design. Application rates were 6.7 Mg ha -1 for poultry litter, 6.7 Mg ha -1 for biochar and lignite, and 134 kg N ha -1 for inorganic fertilizer. Lignite and biochar were only added once.The combination of biochar and lignite with poultry litter and inorganic fertilizer was positively effective on yield and yield components. Integration of biochar with poultry litter and inorganic fertilizer increased lint yield by 42 and 44% as compared with fertilization alone. Cotton leaf area index increased by 34 and 51% when biochar and lignite were combined with inorganic fertilizer in 2020. The leaching loss of postharvest soil NO 3 -N was significantly reduced by 66 and 50% when biochar and lignite were combined with inorganic fertilizer, respectively.
