“…It is clearly evident from results that too early planting (10-March) had experienced sub optimal weather conditions at early growth and later reproductive phases which impact the biomass portioning, source sink relationship and unable to meet the boll demand due to reduction in boll filling period ultimately less seed cotton yield produced than April and May planting (Bange and Milroy, 2004;Yeates et al, 2010;Luo et al, 2014). Although, early planting had longer season, crop growth can be maintained and fruit loss can be remunerated by the new plant growth but longer season duration tied with higher temperature which required more resources as irrigation and fertilizer to attain same or more seed cotton yield (Constable and Bange, 2006;Yeates et al, 2010). Significantly higher heat use efficiency (1.55 to 1.59 kg ha -1 °C days -1 ) was computed for 10-March to 21-April planting while lowest for 21-June planting.…”

“…Lower accrual of day degrees was reported by Bange and Milroy (2004) at early planting for all key phenophases while higher thermal time for all phenological events was accumulated when cotton was planted during peak season (Sawan et al, 2002;Sing et al, 2007). Yeates et al (2010) reported thermal time requirement of different phenological phases planted at variables dates with cotton cultivars, there are variation between results due to differences in climatic conditions and growing seasons but generally overall results are in range (Bange et al, 2008;Luo et al, 2010) while our findings are in line with the study conducted in semi-arid climatic conditions, thermal time was in range for first square, flower, boll initiation and boll opening (633, 861, 1222, 1616 °C days, respectively) but it was only for April planting (Gudadhe et. al., 2013).…”

“…Cotton biomass production is strongly related to time during which plant foliage remained within range of thermal kinetic window (23.5-32 °C), biomass productivity therefore directly influenced by TKW and temperature experienced by the plants during season (Sawan et al, 2002). Early planted varieties (89 and 111 CD) attained higher biomass because these planting harvested supra optimal growth conditions (30/22 °C) at vegetative phase, these climatic conditions enhanced number of nodes to the first fruiting branch which ultimately promote the biomass accretion and faced sub optimal at reproductive phases (40/32 °C) which affect reproductive structure, excessive fruit loss ultimately resulted less seed cotton yield (Reddy et al, 2004;Yeates et al, 2010). In late sown due to shorter time for vegetative growth and lower biomass accretion which unable to support high fruit load, in this condition crop may be moved more quickly to "cutout" and result in the seed cotton reduction (Bange and Milroy, 2004 Fig.…”

Suitable cotton variety selection is imperative to cope with temporal variations for yield enhancement and sustainability under unpredictable climatic conditions. Cotton varieties including transgenic (Bacillus thuringiensis) and non-transgenic (non Bt.) were sown from 10-March to 21-June with 20 days interval for two growing seasons (2012 and 2013) consecutively while cotton sowing after wheat harvest is normal practice at farmers' field in Cotton-Wheat cropping system of Punjab-Pakistan. Phenology, growth indices, seed cotton yield (SCY) and its heat use efficiency of varieties were estimated on daily basis by using statistical models. Seed cotton yield (SCY) was significantly correlated with crop duration exhibiting delays in planting (21-June) impact on shortening of phenophases i.e. first square, flower, boll initiation and boll opening by 8, 7, 4 and 6 days, respectively compared with 10-May planting in first season while second season advanced 0-3 days owing to deviation in frequency of cold shock <11 °C and heat stress >35 °C. Long crop cycle varieties AA-802 and IR-3701 took 6-9 days more compared to short season NIAB-112. More heat units accretion 46, 33, 20 and 13 % to switch into next phenophase (first square, flower, boll initiation and boll opening) was computed in 10-May planting than 10-March due to excessive heat stress (>40 °C) during early phenophases while reduced variations observed in later phases. Reproductive stage initiation and accumulated higher thermal time delayed in late mature varieties compared to short one with lower root mean square error (RMSE) and higher coefficient of determination (R 2 ). Significant reduction in days after planting to attain maximum LAI, CGR, TDM and SCY-heat use efficiency (HUESCY) decreased with delay in planting with good statistical indices. Less impact of cold shock and heat stress on 21-April and 10-May plantings noted while 10-March and 21-June planting had higher incidence during early growth phases. Cotton varieties MNH-886 and NIAB-9811 (NIAB-Kiran) planted 30-March to 10-May exhibited higher resilience to variable weather conditions with fostered growth potential and yield. Variety NIAB-112 seemed heat tolerant and it can be recommend for early and especially for late plating while MNH-886 and NIAB-Kiran can be adopted at farmer's field in the region for maximizing cotton production under variable environment.

“…As the fibre cell elongates to 2.5-3.0 cm within 16 days post anthesis (DPA), it is the longest single-cell structure with the fastest elongation rate in the world (Tiwari and Wilkins 1995). Fibre development is restricted by declining temperature or low light in many cotton-grown areas (Dong et al 2006;Wang et al 2005Wang et al , 2006Yeates et al 2010), and the two climatic conditions often appear as a combined factor during the periods of flowering and boll development of cotton, e.g., in the Yangtze River Valley, cotton often suffers from rainy and overcast weather during the early stages of flowering and boll formation, and is also affected by the declining temperatures accompanying the cloudy and overcast weather at the later stages. The sub-optimal environmental conditions during the fibre elongation phase may decrease the rate of elongation per day or shorten the duration of the elongation period, so that the genotype fibre length potential is not fully realised (Hearn 1976;Bradow and Davidonis 2010;Zhao et al 2012).…”

Declining temperature and low light often appear together to affect cotton (Gossypium hirsutum L.) growth and development. To investigate the interaction on fibre elongation, two cultivars were grown in fields in 2010 and 2011 and in pots in 2011 under three shading levels for three planting dates, and the differences of environmental conditions between different planting dates were primarily on temperature. Fibre length in the late planting date 25 May was the longest instead of the normal planting date. Late planting prolonged fibre elongation period and the effect of late planting on fibre length formation was greater than low light. In the normal planting date, shading increased fibre length through delaying the peak of b-1,3-glucanase gene expression and bringing the peak of b-1,3-glucan synthase gene expression forward, leading to a longer duration of plasmodesmata(PD) closure to increase fibre length, instead of changing sucrose contents or relate enzyme activities. However, in the late planting dates, the difference of the duration of PD closure between shading treatments was not obvious, but low light had a negative impact on sucrose contents, sucrose synthase (SuSy) and vacuolar invertase(VIN) activities during fibre rapid elongation period, leading to the decline of fibre length. Due to late planting and low light, the decreased extent of fibre length of Sumian 15 was larger than Kemian 1. Under the combined condition, Sumian 15 had a shorter gene expression of Expansin, and more sensitive sucrose content, VIN and SuSy activity during fibre rapid elongation period. This resulted in the length formation of Sumian 15 which was more sensitive than Kemian 1, when the cotton suffered the combined effects.

“…Winter flowering often caught in reduced atmospheric humidity, soil moisture and nutrients uptake under minimum temperatures 8°C during fibre elongation ( Figure 2) results in lower micronaire and bundle strength in later pickings (Davidonis et al, 2004;Avgoulas et al, 2005;Wang et al, 2009;Yeates et al, 2010).…”
