Abstract/ Executive Summary:

Experiments were conducted at Agriculture Research Station, BARI Burirhat, Rangpur during rabi seasons of 2004-05 and 2005-06 to find out the effect of lime and boron on the yield and yield attributes of mustard variety BARI Sharisha-9. Three levels of boron (0, 1.0 & 2.0 kg ha^-1) and three levels of lime (0, 1.0 & 2.0 t ha^-1) were tested in the study. Number of siliqua plant^-1, number of seed siliqua^-1, 1000 seed weight and seed yield ha^-1 were significantly influenced by levels of lime and boron application. Seed yield significantly increased and yield attributes improved with the increasing rate of boron and lime. The highest number of siliqua plant -1 (194.6 & 143.66), seeds siliqua^-1 (20.9 & 20.2) and 1000- seed weight (3.3g & 3.2g) were obtained from 2.0 kg ha^-1 of boron and 2.0 t ha^-1 of lime. The highest seed yield 1.83 t ha^-1 and 1.75 t ha^-1 were recorded from 2 kg ha^-1 of boron and 2 t ha^-1 of lime in first and second year respectively which were statistically identical with 1 kg boron ha^-1 and 2 ton lime ha^-1 (1.69 & 1.66) but significantly higher over control.

Location: Agriculture Research Station, (BARI) Burirhat, Rangpur

Start Date: 00-00-2004

End Date: 00-00-2006

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer

Objectives:

To finding out the optimum rate of lime and boron for maximizing the yield of mustard in Tista Flood Plain soil in the northern parts of Bangladesh.

Methodology:

Experiments were conducted at Agriculture Research Station, BARI, Burirhat, Rangpur during rabi seasons of 2004-05 and 2005-06 for two consecutive years. The experimental field was a piece of well drained medium high land with moderately even topography. The area belongs to Tista Floodplain (AEZ-3), noncalcareous alluvium predominates, acidic in nature, having low organic matter and deficient in nitrogen, phosphorus, potassium and boron in comparison with the standard nutrient status. There were two factors - lime and boron application. There were three rates of lime viz. 0, 1.0, 2.0 t ha^-1 in the form of Dolochun and three rates of boron viz. 0, 0.5 and 1.0 kg ha^-1 in the form of boric acid. Initial soil sample of each plot was analyzed for nutritional status. At harvesting stage 10 randomly selected plants were uprooted from each plot to collect data on plant height, number of branches plant, number of siliquae plant^-1, 1000-seed weight, seed yield per plant and seed yield per hectare. Collected data were analyzed statistically.

Achievement/Findings:

It can be concluded from the two years study that 2.0 tons lime in combination with 1 kg boron per hectare were found to be suitable for maximizing yield of mustard variety BARI Sarisha-9 in non calcareous Tista Flood Plain Soil at Burirhat, Rangpur. Therefore, 2 tons lime with 1kg boron per hectare along with the aforesaid blanket dose of other fertilizers may be recommended for sustainable yield of rapeseed and to nourish the soil fertility in Noncalcareous Tista Flood Plain Soil of Northern region of Bangladesh
