Chickpea, Sowing time, Seed treatment, Yield and Quality seed
Agronomy experimental field of Sher-eBangla Agricultural University, Dhaka, Bangladesh during the period from November 2013 to March 2014
Crop-Soil-Water Management
The experiment was conducted at the Agronomy experimental field of Sher-eBangla Agricultural University, Dhaka, Bangladesh during the period from November 2013 to March 2014 to study the effect of sowing time and seed treatment on growth and yield of chickpea. The location of the site is 230 74/N latitude and 900 35/ E longitude with an elevation of 8.2 m from sea level. The soil belongs to “The Modhupur Tract”, AEZ – 28. [16] Top soil was silty clay in texture, olive-gray with common fine to medium distinct dark yellowish brown mottles. Soil pH was 5.6 and has organic carbon 0.45%. The geographical location of the experimental site was under the subtropical climate, characterized by 3 distinct seasons, winter season from November to February and the pre-monsoon period or hot season from March to April and monsoon period from May to October. BARI chhola-6 was collected from Bangladesh Agricultural Research Institute (BARI), Joydevpur, Gazipur. The experiment comprised as two factors one of them sowing date viz. S1: 1st sowing date: 19th November, S2: 2nd sowing date: 29th November, S3: 3rd sowing date: 9th Decemberand on the other factor seed treatment viz. T1: GA3 75 ppm, T2: GA3 150 ppm, T3: GA3 225 ppm, T4: GA3 300 ppm and T5: hydro-priming. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The size of each unit plot was 4.0 × 2.5 m. The spacing between blocks and plots were 1.0 m and 0.5 m. The plot selected for the experiment was opened in the last week of October, 2013 with a power tiller, and was exposed to the sun for a week, after which the land was harrowed, ploughed and crossploughed several times followed by laddering to obtain a good tilth. The fertilizers 50-90-40-10-10@urea, TSP, MP, Gypsum and borax, respectively were applied. The one third amounts of urea and entire amount of TSP, MP, Gypsum, Zinc sulphate and borax were applied during the final preparation of land. Rest urea was applied in two equal installments at vegetative and flowering stage. After establishment of seedlings, various intercultural operations were accomplished for better growth and development of the chickpea. The crop was harvested at full maturity on 08 March, 2014 and harvesting was done manually from each plot. The harvested crop of each plot was bundled separately, properly tagged and brought to threshing floor. Enough care was taken for harvesting, threshing and also cleaning of chickpea seed. Fresh weight of grain and stover were recorded plot wise. The grains were cleaned and finally the weight was adjusted to a moisture content of 12%. The stover was sun dried and the yields of grain and stover plot-1 were recorded and converted to t ha-1. Data were collected on date of emergence, date of 1st and 50% flowering, plant height (cm), number of branches plant-1, total dry matter, number of pods plant-1, days to pod maturity, pod length plant-1, number of seeds pod-1, weight of 1000 seeds (g), grain yield (Kg ha-1), stover yield (Kg ha-1), biological yield (Kg ha-1), harvest index (%), germination (%) and vigor index. The data obtained for different characters were statistically analyzed to observe the significant difference among the treatment by using the MSTAT-C computer package program. The significance of the difference among the treatments means was estimated by the Duncan’s Multiple Range Test (DMRT) at 5% level of probability.
