Effect of Planting Dates on the Yield of Mustard Seed

Abstract

The experiment was conducted at Shibganj upazila under Bogra district during October, 2014 to January, 2015 to observe the effect of planting dates on the yield of mustard seed. There were five planting dates viz. 25 October, 30 October, 05 November, 10 November and 15 November. Significant variations due to different planting dates were observed in plant height, number of leaves plant-1, number of siliqua plant-1, number of seed siliqua-1, 1000 weight plot-1, yield plot-1and yield ha-1of mustard. Results showed that the highest seed yield was1.50 t ha-1 obtained from 30 October. The lowest seed yield was 1.0 t ha-1 from 15 November. From the results, the best planting date of mustard is on 30 October in the northern parts of Bangladesh. Int J Appl Sci Biotechnol, Vol 3(4): 651-654

Phenological and Growth Responses of Indian Mustard (Brassica juncea L.) Genotypes to Different Sowing Dates

“…low temperature at vegetative phase and high temperature at reproductive phase in 21 November sown crop might have resulted into decreased plant growth rate. Similar results due to sowing dates has also been reported earlier in the literature (Muhal and Solanki (2014) in Brassica juncea; Alam et al, (2014) in Brassica napus; Khayat et al, (2015) in canola). At 120 DAS there was no significant difference of relative growth rate in different dates of sowing and genotypes.…”

“…This might be due to the reason that the favourable temperature prevailing on 16 October sown crop might have resulted into timely flowering while on 21 November sowing the low temperature might have extended the vegetative phase that resulted into delayed flowering in 21 November sown crop. Similar results due to different sowing dates have also been reported earlier in the literature (Khayat et al, (2015) in canola; Alam et al, (2014), Solanki and Mundra (2015) in Brassica juncea; Akhter et al, (2014) in Brassica rapa). Among all six genotypes, RH-725 took least number of days (46.7) to 50 % flowering followed by RH-0116 (47.1) and maximum number of days was taken to 50 % flowering by RH-1019 (49.5) when considered irrespective of sowing dates.…”

“…This is because of variation in different genotypes in their genetic makeup which is well reported in the literature (Muhal and Solanki (2014); Alam et al, (2014). The minimum crop growth rate (2.57 g m -2 day -1 ) was observed in plants sown on 21 November and maximum crop growth rate (3.59 g m -2 day -1 ) was observed on 23 September sown crop when considered irrespective of genotypes.…”

Storage pests of maize and their status in Bangladesh

“…Traditionally, maize grain is stored by Bangladeshi farmers, both in and outdoors for consumption and sell in the later months of the year depending on the quantity produced per household. Maize seed like also mustard seed (Alam et al 2015) has to be stored from harvesting to next planting season (usually about 7-9 months) and safe storing of maize seed (like as onion) has become an important issue in Bangladesh (Mollah et al 2016).…”
