“…An imbalanced nutrient profile can affect cotton yield even if phosphorus levels are sufficient (Sekhon and Singh, 2013;Iqbal et al, 2020;Solangi et al, 2023). The interaction between sowing dates and phosphorus levels is not significant for plant height, suggesting that the effect of sowing dates on plant height is consistent across different phosphorus levels, and vice versa (Iqbal et al, 2023). Similarly, the interaction is not significant for the number of leaves per cotton plant, implying that the influence of sowing dates on the number of leaves and the influence of phosphorus levels on the number of leaves are consistent and do not interact significantly (Khan et al, 2019).…”

This study assessed the effects of sowing dates and phosphorus levels on cotton performance in Chato-Msilale village in Chato District, Tanzania. The soil analysis revealed that field exhibited slightly acidic soil with normal electrical conductivity but suffered from severe deficiencies in total nitrogen and organic carbon. The same field presents common issue of low cation exchange capacity, indicating limited nutrient-holding capacity. Furthermore, both fields displayed very low levels of total nitrogen (<0.1%), signaling a nitrogen deficiency. Available phosphorus was rated as medium (16.8 mg kg−1 soil). Trace elements fluctuated and could be managed based on specific crop requirements. The factors at different levels were: (1) sowing dates – (i) 25th November 2022, (ii) 15th December 2022, and (iii) 4th January 2023; and (2) Phosphorus levels – (i) control, (ii) 20 kg P ha−1, (iii) 40 kg P ha−1, and (iv) 60 kg P ha−1. Regarding cotton growth and yield, sowing dates significantly (p < 0.001) influenced plant height, gin turnout, lint yield, number of bolls per plant, and boll weight while phosphorus levels did not exhibit significant effects. Earlier sowing dates resulted in higher yields, albeit with variations in yield components. Interactions showed that growth and yields were only numerically higher in the middle sowing date at higher levels of phosphorus applied. Overall, these insights offer valuable guidance for optimizing cotton cultivation in Chato District, emphasizing the importance of selecting appropriate sowing dates for improved yields.

“…Mahdi et al (2019) reported that early planting (1 st April) is suitable for the Egyptian cotton genotypes, especially Giza 95, through the appropriate climatic window that corresponds to the different growth stages to produce higher production by creating a good equilibrium between vegetative growth and fruiting ability and maximizing the activity utilization of heat thermal units. The most important and most manageable factor for cotton yield is the optimal time to plant the new variety in the area (Iqbal et al, 2023). The environment change affects agricultural production by affecting managing practices like planting time.…”

Two field experiments were executed during the 2021 and 2022 seasons at Sids Agricultural Research Station, in Beni-Suef Governorate, Egypt to study the effect of foliar spraying with two growth regulators, i.e. indole -3-butyric acid (IBA) at two levels (20 and 50 ppm) and 1-naphthalene acetic acid (NAA) at two levels (30 and 50 ppm) in addition to the control (spraying only water) under two planting dates (during April and May) and their interactions, on growth, chemical composition, water relations, fiber quality, and productivity of cotton Giza 95 var. Data indicated that early planting date (1st April), foliar spraying with 50 ppm of IBA and their interactions resulted in significant increase on leaf photosynthetic pigments, total soluble sugars, N, P, K, IAA, GA3, and kinetin concentration, leaves total water content and relative water content in both seasons and significantly decreased proline, phenols, ABA, and plasma membrane permeability (which supports and confirms membrane integrity). In addition, early planting date (1 st April) and foliar spraying with 50 ppm of IBA resulted in a significant increase in sympodia, open bolls number/plant, earliness percentage, and seed cotton yield/fed in both seasons, boll weight, and seed index in the second season only. The interaction between them gave the best results. It is advisable to apply early sowing and spraying IBA at 50 ppm twice (at start and top of flowering) to realize the most efficient effects on improving productivity and increasing the efficiency use of heat units.

Cotton crop is an imperative role in Pakistan’s economy. It faces several environmental situations which check its growth and production. Climate changes bring a head new pressure for cotton cultivation in the Pakistan especially in Sindh province. The present study was carried out at Nuclear Institute of Agriculture (NIA), Tandojam in 2021. Four advance lines NIA-88, M-32, NIA-Bt. 89 and NIA-Bt.90 along with two local check varieties IUB-2013 and CRIS-121 were evaluated under two planting dates viz. 1st April and 1st May having three replicates under randomized complete block design with factorial arrangements. The data depicted that crop sown on 1st April produced more seed cotton yield (2855.5 kg ha-1) than sown on 1st May with (1674.4 kg ha-1). Comparing the average varietal performance in both sowing dates, NIA-88 produced maximum seed cotton yield (2339.2 kg ha-1) while minimum seed cotton yield (2137.2 kg ha-1) was exhibited by check variety CRIS-121. Boll retention % was maximum (44%) in advance line NIA-88. The maximum number of bolls plant-1 (42.0), sympodial branches plant-1 (26.0), ginning out turn percentage (42.0), seed index (8.1g) and staple length (29.0mm) respectively was obtained in 1st April sowing date while minimum number of bolls plant-1, sympodial branches plant-1, ginning out turn percentage, seed index and staple length (33.0), (15.0), (36.3), (6.0g) and (27.0mm) took in 1st May sown crop. Associating the average varietal performance in both sowing dates NIA-88 produced maximum number of bolls plant-1(44.0), sympodial branches plant-1 (23.0), ginning out turn percentage (40.4), seed index (9.0g) and staple length (29.0mm) respectively. The results indicated that the planting dates and genotypes influenced on seed cotton yield and associated traits in current changing climate scenario for cotton crop.
