Abstract/ Executive Summary:

Boron (B) is an essential micronutrient of mustard and play a vital role on its normal growth, and development. A study was conducted at (AEZ-20) Shiberbazar, Sylhet during November 2016-February 2017, to quantify the effect of boron on yield and yield attributes of mustard (BARI Sarisha-14), and different doses and form of B application. Randomized Complete Block Design (RCBD) was followed with three replications to design the study. Five B (boric acid) levels viz.T1 = basal application of B @ 2kg ha^-1; T2 = foliar spray (FS) of B @ 0.5% at vegetative stage (VS) ; T3 = FS of B @ 1% at VS; T4 = FS of B @ 0.5% at VS + pod formation stage (PFS) and T5 = FS of B @ 1% at VS + PFS and T6 = control (no boron) were used. Results indicated that yield and yield attributes of mustard were significantly influenced by boron application. The effects of boron were significant on number of siliquae plant^-1, number of seeds siliqua^-1, seed yield, stover yield, 1000-seed weight, biological yield and harvest index (%). The highest number of siliquae plant-1(35.93), number of seeds siliqua-1(30.03), stover yield (1946.0 kg ha^-1) and 1000-seed weight (3.617 g) were obtained from the treatment T5. The seed yield (801.17 kg ha^-1) was found also in the treatment T5 which was over double than control (T6). Therefore, two times foliar application of B @1% at VS and PFS is a good option to increase yield and yield contributing characters of BARI Sarisha-14 in AEZ 20.

Commodity: Fertilizer, Mustard

Objectives:

This study was designed to ascertain proper application method and rate to increase grain yield and improving yield contributing characters of high yielding mustard variety BARI Sarisha-14.

Methodology:

To quantify the proper application methods and rate of boron fertilizer in BARI Sarisha-14 an experiment was conducted under Farmer’s field at Sotero Tekerbari, Shiberbazar, Sylhet Sadar, Sylhet under Surma-Kushiyara Floodplain (AEZ-20) during the period of November 2016 to February 2017. The soil was clay loam having a pH value of 4.80, low in fertility status having available phosphorus 0.05 μg g^-1 soil, exchangeable potassium 0.05 meq 100 g^-1 soil, low amount of nitrogen and boron but available sulphur was 25 μg g^-¹ soil, organic matter content was 1.82%. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Each replication was divided into six plots where different doses of boron were applied according to treatments. The unit plot size was 6 m × 4.15 m (24.9 m²≈25 m²). The experiment was comprised of 6 treatments viz.T1= Basal application of boric acid (BA) @ 2 kg ha-1 during final land preparation; T2= Foliar spraying (FS) of BA @ 0.5% at vegetative stage; T3= FS of BA @ 1% at vegetative stage; T4= FS of boricacid @ 0.5% at vegetative stage + pod formation stage; T5= FS of BA @ 1% at vegetative stage + pod formation stage; T6= Control (no boron applied). The experimental plots were fertilized at the rate of 150-110-90 and 120 kg ha^-¹ N-P-K and gypsum (BARC, 2012). Boric acid (Bingo, 20 % Boron) was used as the source of boron and applied according to experimental treatment set up. Seeds were sown on 24 November, 2017 at the rate of 8.5 kg ha-1 and crop was harvested at 76 DAS. Intercultural operations such as weeding, thinning, irrigation, spraying of insecticides and weedicides were done uniformly. Different growth parameters were recorded from different days after sowing of seeds for observing effect on plant growth. At harvesting stage, randomly 10 sample plants were uprooted from each unit plot to collect data on different yield contributing characters and 1 m × 1 m area was selected for yield data. Data were analyzed by statistical analysis program “R”. The significance of the mean differences among the treatments was estimated by the Least Significant Deferent Test (LSD) at 5% level of probability (Gomez et al.1984).

Achievement/Findings:

The yield contributing characters of brassica genotype perform well in two times foliar application of B at vegetative and pod developmental stages,and that finally leaded to higher seed yield. The foliar application of B @1% found as effective application method and rate in this study. However, 1% rate of B for foliar application was maximum dose in this study and showing increasing tread. Therefore, it is very difficult to precisely recommend this rate and method of B application for whole AEZ-20 as the study was conducted in only one location. Multi-location study with same setup with another above 1% two or three doses of B is necessary to finally conclude the proper application rate and method.
