Abstract/ Executive Summary:

A field experiment was carried out at Calcareous Brown Floodplain Soil of Regional Agricultural Research Station, Jessore during the two consecutive seasons of 2000-2002. The objectives were to evaluate the effect of boron on the yield of mustard and to screen out the suitable variety (s) tested against different boron levels for maximizing yield of mustard in the study area. Four varieties of mustard viz., BARI Sharisha-6, 7, 8 and 9 and 4 levels each of boron (0, 1.0, 1.5 and 2.0 kg ha^-1) along with a blanket dose of N₁₂₀P₃₅K₆₅S₂₀Zn₅ kg ha^-1 and cowdung 5 t ha^-1 were taken in the study. Results revealed that BARI Sharisha-6 integrated with 1.5 kg B ha^-1 was found to be superior to all other treatment combinations. The highest mean seed yield (1.96 t ha^-1) was recorded with the said treatment by 25.64% yield increase. Among the 4 tested varieties of mustard, BARI Sharisha-7 showed a good performance and produced the highest mean yield (1.77 t ha^-1) as compared to other varieties used. On the other hand, boron at the rate of 1.5 kg ha^-1 individually increased the highest seed yield by 58.83%, over boron control (Bo). However, from regression analysis, a positive but quadratic relationship was observed between seed yield and boron levels.

Start Date: 00-00-2000

End Date: 00-00-2002

Program Area: Crop-Soil-Water Management

Commodity: Mustard

Objectives:

The present study was designed to screen out the variety(s) and to find out the optimum requirement of boron for yield maximization of mustard in southern part of Bangladesh.

Methodology:

The field experiments were conducted in Calcareous Brown Floodplain Soil (EPZ-11) at Regional Agricultural Research Station, Jessore during the rabi seasons of 2000-2001 and 2001-2002, respectively. The nutrient status of initial soil was recorded. The experiment was laid out in randomized block design replicating thrice. It was a factorial experiment with 4 levels of B (0, 1.0, 1.5 and 2.0 kg ha^-1) and 4 varieties of mustard viz., BARI sharisha-6, BARI sharisha-7, BARI sharisha-8 and BARI sharisha-9 were tested in the study. Sixteen different treatment combinations were constituted for verification. The unit plot size was 4x5 m and the seeds were sown in mid November for both the years by maintaining 30 cm row to row distance apart. Boric acid was used as a source of boron. Four levels each of B (0, 1.0, 1.5 and 2.0 kg ha^-1) along with a blanket dose of other chemical fertilizers (N₁₂₀P₃₅K₆₅S₂₀Zn₅ kg ha^-1 and CD at the rate of 5 t ha^-1) were taken in the test. All P, K, S, Zn, B and CD and ½ of N were applied at the time of final land preparation and remaining ½ N was top dressed prior to flowering. Irrigation and other intercultural management practices were done as and when necessary. The crop was harvested on 15th March for both the seasons. The necessary data on different parameters wee recorded form 10 randomly selected plants. Then it was computed and analyzed statistically. The analyzed data was adjusted with Least Significant Difference (LSD) at 5% level.

Achievement/Findings:

It can be concluded from two years study that B at the rate of 1.5 kg ha^-1 along with a blanket dose of N₁₂₀P₃₅K₆₅S₂₀Zn₅ and cowdung 5 t ha^-1 was found to be the best combination for all the varieties tested in the study area of Calcareous Brown Floodplain soil of Jessore. So, the said package of combination may be recommended for sustainable yield of mustard in the study area.
