Effect of sowing dates and varieties on productivity of maize in terai region of Nepal
An experiment was conducted in two years (2009/10-2010/11) at Rampur, Chitwan Nepal to study effect of sowing date and varieties on yield of maize. Three varieties namely Rampur Composite, Arun-2 and Gaurav were sown at every week from April to March. The design was randomized complete block design with four replications (week as replication). The result showed that interaction effect of variety and sowing date on grain yield of maize was significant. Rampur Composite and Arun-2 produced highest yield in August and lowest yield in May and Gaurav yielded highest in September and lowest in November. The sowing date was highly significant for grain yield. The highest production was 5.120 tha-1 in August followed by February (4.922 ton ha-1), September (4.626 ton ha-1) and March (4.395 ton ha-1) respectively. The lowest yield was of month May (2.376 ton ha-1).Therefore it was concluded that August planting was best for higher grain production

Crops are the main source of human food supply and among them, grains are more important, among cereals, corn (Zea mays L.) is an important crop due to its high grain and forage yield potential. The research experiment was conducted on maize to find out the effect of different sowing dates and plant density among three genotypes on the performance of maize, in the spring of the 2020 growing season in the Bagh-e-Zakhirah Research Farm of Takhar province Afghanistan. The experiment was laid out as a split-plot factorial in a randomized complete block design (RCBD) with three replications. Three planting dates (May 5, May 21, and June 5) as the main factor, three plant densities of 6.5, 8, and 10 plants/m2, and three genotypes, SC260, SC600, and SC302 were considered as sub-factors. All treatments sowing date, plant density, genotype, and only interaction effect of sowing date × plant density showed significantly different effects (P< 0.01) on yield and yield components. The results of the present investigation revealed that the highest grain yield 6.99 ton/h was obtained from the sowing date (May 5) and plant density of 6.5 plants/m2 and the lowest grain yield 6.21 ton/h was obtained from the sowing date (June 5) and plant density of 10 plants/m2. In general, the results showed that the sowing on the 5th of May is superior to the 5th of June in terms of grain yield and yield components, and among the three corn genotypes, the SC260 genotype is more batter than the SC600 and SC302 genotypes under the environment condition. Therefore considering all results the first week of May as the sowing date and 65000 plants/h with SC260 genotype could be recommended to the maize grower for the most effective for producing maize.

Sowing dates and varieties affect the productivity of maize. A field experiment was conducted to find out the response of maize hybrids to sowing dates on growth and productivity of maize in spring season at Lamahi, Dang in 2019. The experiment was laid out in two factor factorial Randomized Complete Block Design with four replications. The treatment consisted of combination of three different sowing dates (February 1, February12 and February 23) and two maize varieties (Arun-2 i.e. OPV and hybrid Bioseed-9220).The result revealed that earlier planting on February 1 produced the highest yield (8265 Kg ha-1) which was significantly superior than latter planting of February 12(6099 kg ha-1)and February 23 (5934 kg ha-1).The higher yield in earlier planting was due to significantly higher no of kernel per ear, non-significant but higher number of cob per unit area, thousand grain weight. Similarly, Bioseed 9220 produced higher yield (7798 kg ha-1) compared to Arun-2 (5,734 kg ha-1). Th...

The rapid climate changes are imperative to evaluate and find ways that suite to maize-specific varieties either hybrids or varieties with appropriate sowing dates to avoid the critical growth stages from the stresses due to climate condition. Sowing at proper time and selection of good verity are the most important factor cropping system. A field experiment was conducted at the University of Agriculture Research Farm during summer 2016 to evaluate the influence of sowing dates on varying maize varieties grown under the agro-climatic condition of Peshawar. The experiment was laid out in RCBD (randomized complete block design) were replicated three times with split plot arrangement. Sowing dates (10 June, 21 June, 1 July, 11 July, 22 July) were allotted to main plot and varieties (Iqbal, Azam, Jalal, Babar, SB-989, SB-909, SB-292, CS-200, CS-220, and W-888) were placed in the subplot. The subplot size was 5 m × 3 m. Experimental result showed that maximum days to tasseling (60), days to silking (65), tasseling and silking interval (6), plant height (185 cm), biological yield (21745 kg ha-1), 1000 grain weight (413 g) grain yield (5162 kg ha-1) were observed in different sowing intervals. Among the different verities the maximum days to tasseling (57), days to silking (62), tasseling and silking interval (7). Plant height, (176 cm), biological yield (17279 kg ha-1), 1000 grain weight (410 g), grain yield (5113 kg ha-1). It is concluded from the result that early sowing and tested variety W-888 give higher grain yield and yield traits of maize.
A field experiment was conducted during Kharif 2012 to study the effect of different dates on yield attributes and yield of different maize (Zea mays L.) hybrids. The experiment consists of four dates of sowing (15th June, 25th June, 5th July and 15th July) in main plot and five maize (Zea mays L.) hybrids of different maturity groups namely, HQPM-1 (long), HM-4 (medium), HM-5 (long), HM-6 (early) and HM-7 (extra early) in sub plot was replicated thrice in split plot design. The 10 days advance, normal and 10 days delayed sowing from normal sowing date being at par recorded significantly higher cob length, cob girth, 100 grain weight, shelling per cent and grain yield/ha as compared to delayed sowing by 20 days from normal sowing date. Highest cob length was recorded in HM-4 (15.6 cm) followed by HQPM-1 (14.2 cm), HM-6 (13.4 cm), HM-7 (12.9 cm) and lowest in HM-5 (12.1 cm). Highest shelling per cent was recorded in HQPM-1 (67.8 %) followed by HM-6 (65.1 %), HM-4 (63.6 %), HM-7 (62.3 %) and lowest in case of HM-5 (58.5 %). Hybrid HM-5 recorded highest cob girth (4.3 cm), 100-grain weight (27.0 g), grain yield (7.64 t/ha) and highest nitrogen, phosphorus and potassium uptake in grains and straw.

Our Nature, 2015
Genotypic yield potential of maize genotypes is greatly affected by planting dates. This study was conducted to determine optimum planting dates of maize genotypes in 2013/14 at Rampur, Chitwan, Nepal. Four genotypes namely RML-4/RML-17, RML-32/RML-17, ACROSS-9944/ACROSS-9942 and S99TLYQ-B were planted at every week from April to March. The experiments were laid out in randomized complete block design with four replications . The result of experiment showed that the highest production (5565 kg/ha) was obtained in August followed by February (5266 kg/ha), June (4475 kg/ha) and July (4255 kg/ha) respectively. The lowest yield (2572 kg/ha) was obtained in the month of November and December planting (3019 kg/ha). The highest grain yield was obtained in RML-4/RML-17 (7392 kg/ha) and RML-32/RML17 (6606 kg/ha), ACROSS-9944/ACROSS-9942 (5004 kg/ha) during August planting and higher yield of QPM variety S99TLYQ-B was obtained in the month February planting. Winter maize has higher production potential than the rainy season maize. Based on this experiment RML-4/RML-17, RML-32/RML17 and ACROSS-9944/ACROSS-9942 should be planting in August (winter season) and S99TLYQ-B in February (spring season) for higher grain yield production.

Journal of Krishi Vigyan, 2020
ABSTRACT The research experiment was conducted on maize in order to find out the effect of different sowing dates on the performance of maize at Entomology Field Laboratory, Department of Entomology, Bangladesh Agricultural University (BAU), Mymensigh during Rabi season of 2016-17. The experiment was laid out in randomized complete block design (RCBD) with three replications. BARI Hybrid Butta-09 variety of Maize and nine sowing dates viz. 3rd(S1) & 4th(S2) week of October; 1st(S3), 2nd(S4), 3rd(S5) & 4th(S6) week of November; 1st(S7), 2nd(S8) & 3rd(S9) week of December were used as experimental crop and sowing dates, respectively.All sowing dates showed significantly different effect on yield. The results of present investigation revealed that maximum morpho-physiological characters, yield components and yield was obtained with better quality sown on 1st week of November as sowing dates than others due to ensuring the highest plant height (223.66cm), number of cob/ plant (1.73), cob length without husk (23.23cm), number of grain/ cob (641.21), grain weight/cob(235.16) and maximum grain yield (10.56 t/ha), which was followed the increasing order of yield were S4<S5<S6< S7< S8< S9< S2< S1.In case of correlation between different sowing dates and yield, the present study showed that very strongly significant negative correlation between sowing dates and grain yield of maize. Therefore, considering all facts, 1st week of November as sowing date could be recommended to the maize grower for the most effective for producing of maize. Henceforth, in addition, 2nd week of November could also be suggested for second best effective sowing date where second crop of cropping pattern is not available or not apply in the field.

In order to determine the effects of sowing date on physiological characteristics, yield and yield components of six sweet maize hybrids, an experiment was arranged in split plot based complete randomized block design with three replications. Sowing date in two levels (15 June and 1 July) and sweet maize hybrids in six variants (‘Chase’, ‘Temptation’, ‘Challenger’, ‘Basin’, ‘Obsession’ and ‘Ksc403su’) were the treatments. Results of ANOVA revealed significant difference of sowing date and sweet maize hybrids on the number of days for tassel emergence, number of days to anthesis, plant height, cob height, stem diameter, plant dry weight, cob dry weight, number of grain rows, length flowers, number of leaf above the cob, raffinose content of grain and grain yield. Mean comparisons showed that the highest grain yield was obtained for ‘Basin’ variety and it was obtained from the crop established on the 15th of June as planting date. In temperate regions, maize potential productivity see...

The effect of sowing date, N fertilisation and genotype on the grain yield and yield stability of maize was studied between 1991 and 2006 in a long-term N fertilisation experiment set up on chernozem soil in Martonvásár, Hungary. The N treatments (0, 60, 120, 180 and 240 kg ha −1 ) represented the main plot of the three-factor, split-split-plot experiment, with the sowing date (early, optimum, late, very late) in the sub-plots and hybrids from different maturity groups in the sub-sub-plots. The highest yields were obtained for the early and optimum sowing dates (8.712 and 8.706 t ha −1 ). Compared with the optimum sowing date, a delay of ten or twenty days led to yield losses of 5% and 12.5%, respectively. In the late and very late sowings and in years with unfavourable weather conditions, yield increments were only observed up to an N rate of 60 kg ha −1 , while in the early and optimum sowings and in favourable years yield increments were significant up to 120 kg ha −1 N.
