Abstract/ Executive Summary:

A field experiment was conducted at the Agronomy research field of Sher-e-Bangla Agricultural University, Dhaka, 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 experiment comprised as one factor: sowing date - 3 times: 1^st sowing date: 19^th November – S₁, 2^nd sowing date: 29^th November – S₂ and 3^rd sowing date: 9^th December – S₃. The experiment was laid out in Randomized Complete Block Design (RCBD) with five replications. The result indicated significant variations in date of emergence, date of first flowering, date of 50% flowering, plant height, number of branches plant^-1, total dry matter content, number of pod plant^-1, date to pod maturity, pod length, weight of 1000 seed, grain yield, stover yield, biological yield, harvest index, germination percentage and vigor index due to sowing time. Among the treatment on maximum plant height and dry matter content recorded of plant in S₂ irrespective of growing period. This treatment also exhibited maximum number of pods plant^-1, longest pod length and maximum number of seed pod^-1, where as required minimum duration for pod maturity. The maximum weight of 1000 seed, highest grain yield, harvest index and also found maximum germination percentage and vigour index were found when chickpea was sown on 29^th November and ensure the best performance.

Keywords: Chickpea, Sowing time, Growth, Yield and seed quality.

Location: Agronomy experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh

Start Date: 00-11-2013

End Date: 00-03-2014

Program Area: Crop-Soil-Water Management

Commodity: Chickpea

Objectives:

To select appropriate time of sowing of chickpea.

Methodology:

The experiment was conducted at the Agronomy experimental field of Sher-e-Bangla 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 23074/N latitude and 90⁰35/E longitude with an elevation of 8.2 m from sea level. The soil belongs to “The Modhupur Tract”, AEZ – 28. 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, Joydevpur, Gazipur. The experiment comprised as one factor of sowing date viz. S₁: 1^stsowing date: 19^th November, S₂: 2^nd sowing date: 29^th November, S₃: 3^rd sowing date: 9^th December. The experiment was laid out in Randomized Complete Block Design with five replications. The size of each unit polt 4.0 × 2.5 m. The spacing between blocks and polts 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 cross-ploughed 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 amount 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 1^st 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.

Achievement/Findings:

In this experiment, the maximum grain yield, harvest index, germination percentage and vigor index was observed from S₂. So, the chickpea cultivation was suitable on 29^th November to “The Modhupur Tract”, AEZ – 28.
