SHEKH, MD. NAZMUL ISLAM
A field experiment entitled “Effect of foliar application of micronutrients on growth,
yield and oil quality of sesame (Sesamum indicum L.)” was conducted during Kharif-1
2017 at central farm of SAU, Dhaka and chemical analysis were done in the laboratory
of BARI, Gazipur. Sesame (Sesamum indicum.L) is one of the most valuable oilseed
crops whose seeds are used as traditional health food, with high quality oil, protein and
natural antioxidants. The experiment was laid out in a Randomized Block Design with
ten treatments and replicated thrice. The treatments were comprising of T
1
: control (no
micronutrients), T
2
: B (100 ppm), T
3
: Zn (100 ppm), T
4
: Mo (50 ppm), T
5
: Cu (100
ppm), T
6
: Fe (100 ppm), T
7
: Mn (100 ppm), T
8
: Co (50 ppm), T
9
: (combination of above
micronutrients) and T
10
: commercial mixture of micronutrients. Observations on plant
height, number of branches, total dry matter, growth analysis parameters, chlorophyll
content of leaf at various stages of crop, yield and yield attributes, oil content and N, P
and K uptake by plant and plant parts were recorded. The results revealed that most of
the putative morphological traits like plant height, number of branches, total dry matter
of plant and plant parts increased with foliar application of different micronutrients but
significantly the highest increase was found when micronutrients were applied in
combination followed by individual application of Zn, B and Mo. Physiological growth
parameters such as leaf area index, leaf area duration, relative growth ratio , net growth
ratio , crop growth ratio and chlorophyll content of leaf increased significantly by foliar
application of different micronutrients either in single or in combination. Seed yield in
sesame increased significantly over control by foliar application of different
micronutrients used in single or in their combination. In view of such beneficial effects
of foliar application of micronutrients on sesame, it may be asserted that improvement
in productivity of sesame can be achieved under a depleted soil condition through
supplementary application of micronutrients viz. B, Zn, Mo, Cu, Fe, Mn, Co, either in
single or their combination along with basal dose of N, P and K.

In case
of combined effect of variety and

A pot experiment was conducted at the net house of Agro-Environmental Chemistry
Laboratory of the Department of Agricultural Chemistry, Sher-e-Bangla Agricultural
University, Dhaka-1207, during the period from November 2017 - August 2018 to
find out the alleviation of adverse effects of salt stress in tomato by foliar application
of salicylic acid. The experiment comprised of two factors: Factor-1. Salinity levels:
0, 3, 6 and 9 dSm
-1
and Factor- 2. Rate of salicylic acid: 0 mM, 0.5 mM, 1 mM and
1.5 mM. BARI tomato -14 was used as the test crop. Data were taken from plant
height, leaves plant

, number of branches plant

flowering from
transplanting, number of flower cluster

, K, Na, Ca and P content in fruit. When single effect was considered, salinity
adversely affected most of the growth and yield parameters and nutrient content
except Na, but application of salicylic acid elevated all the mentioned parameters.
When combined effect was considered, maximum plant height (70.33 cm), leaves
