The comparative growth and yield performances between two Mungbean (BARI Mung 6 and BARI Mung 5) varieties with foliar application of GA3 (0, 50, 100 and 150 ppm) were studied to find out the suitable variety and optimum level of GA3 application. The design of experiment followed was RCBD. Data on morpho-physiological characteristics were recorded at 15, 25, 35, 45and 55 days after sowing (DAS) and yield contributing parameters were recorded only at harvest stage. The results showed that application of GA3 @ 100 ppm produced better performance on morpho-physiological characters namely, plant height (56.59cm), number of leaves per plant (10.75), branches per plant (4.75), length of root (24.73cm), total dry matter weight (12.67g)which were recorded from the variety BARI mung 6 with the foliar application of GA3 @ 100 ppm. Yield contributing characters were also showed the highest performance in terms of number of pods per plant (23.40), pod length (6.67cm), number of seeds per pod (12.82), thousand seed weight (33.95 g), seed yield (7.53 g/plant and 1.92 t ha–1), and harvest index (35.36%) which were the highest with the application of 100 ppm GA3 in case of BARI Mung 6. Single and combined effects of treatments were found statistically significant. Between two varieties BARI Mung 6, among the treatments GA3 @ 100 ppm as foliar application and interaction effect of GA3 @ 100 ppm and BARI mung 6 showed the highest performance in respect of all growth and yield parameters.

An experiment was conducted at the research field of the Department of Agricultural Botany, Patuakhali Science and Technology University, Patuakhali under the Agro-ecological zone-13 (AEZ-13) during the period from November 2012 to February 2013. The aim of the study was to identify the most effective irrigation level for obtaining the better growth and higher yield performance of BARI Gom-25 that are suitable to cultivate under  coastal region of Patuakhali, Bangladesh. So, the present study was consists of five irrigations levels including control viz. control or no irrigation (T0), one irrigation at 25 DAS (T1), two irrigations at 25 and 40 DAS (T2), three irrigations at 25, 40 and 55 DAS (T3)  and four irrigations at 25, 40, 55 and 70 DAS (T4). The seeds of BARI Gom-25 were collected from the BARI, Joydebpur, Gazipur on 22 November, 2012. The experiment was laid out in completely randomized block design (RCBD) with four replications and analysis was done by the MSTAT-C package program where means were separated by DMRT at 5% level of probability. Data were recorded on various growth and yield attributing traits. The plot size was 5 m2 (2.5 × 2.0 m) where row to row and seed to seed distances were 20 and 10 cm respectively. Data were collected on various morpho-physiological growth, yield and yield attributing traits. Results obtained from the present study, whole characters of the study were significant at 5% by the moisture (irrigation) levels where three irrigations given at 25, 40 and 55 DAS had most effective than that of other moisture levels and no irrigation. From the results investigation, it was found that the tallest plant (76.86 cm), maximum requiring days to anthesis (61.00 days), maturity (109.0 days) and maximum number of effective tillers (5.00 hill-1),the highest grain growth (3.11g at 36 DAA) and grains (44.00 spike-1) were obtained with three irrigation (T3) levels. Similarly, T3 further showed the greater performance on spike length (17.28 cm), 1000-seed weight (50.16 g), grain (4.16 t ha-1), straw (5.89 t ha-1) and biological yield (10.05 t ha-1) as well as the higher harvest index (41.39%). Investigated above whole characters were produced lower performances under no moisture (irrigation) treatments. These results indicated that irrigation at three times (T3) would be most advantageous irrigation levels for wheat production under the studied non saline ecosystem of coastal region.Progressive Agriculture 29 (2): 99-106, 2018

Source-sink manipulation may improve light interception into the canopy and reduce the competition between vegetative and reproductive sinks during seed filling period, and may help in achieving higher yield. So, an effort was made to assess the effect of source-sink manipulation on yield contributing characters and yield of sesame. The experiment was laid out in two factors randomized complete block design consisted of two varieties of sesame viz.Binatil-3 and Local-Black and five levels of source-sink manipulation viz.control (M0), removal of lower empty leaves, lower empty branches and top of the inflorescence (M1), removal of top of the inflorescence (M2), removal of all branches and removal of lower empty leaves (M3) and lower empty branches (M4) with three replications. Source-sink manipulations were imposed during capsule development stage (50 days after emergence). Results revealed that the higher number of capsules plant-1 (16.17), seeds capsule-1 (53.27), maximum 1000-seed weight (2.72 g), higher seed capsule wall ratio (2.52), seed yield plant-1 (2.35 g), yield (938.96 kg ha-1) and harvest index (36.40%) were produced by the modern variety Binatil-3 than the traditional variety Local-black. Source-sink manipulation showed positive response to yield attributes compared with control. Maximum seeds capsule-1 (57.13), 1000-seed weight (2.92 g), higher seed capsule wall ratio (2.71), seed yield plant-1 (2.78 g) and yield (1110.96 kg ha-1) were found from removal of lower empty leaves, lower empty branches and top of the inflorescence (M1). Yield was increased by 71.77%, 46.88%, 8.52% and 22.45% due to M1, M2, M3 andM4 manipulation. Although all the source-sink manipulation treatments gave higher yield in their respective variety, the highest (1258.63 kg ha-1 and 125.04%) yield was obtained when lower leaves, lower empty branches and top of the inflorescence of the variety Binatil-3 were removed i.e. from V1M1 treatment. Therefore, Binatil-3 with removal of lower empty leaves, lower empty branches and top of the inflorescence manipulation was the best treatment in respect of yield and yield contributing characters of sesame.Progressive Agriculture 29 (1): 1-9, 2018

The present study was conducted at the research field of Patuakhali Science and Technology University (PSTU), Patuakhali during the period from December 2013 to March 2014 to study on the effect of a concentrated fertilizer (Cropmax) on the growth and yield the Mung bean. It also observed the comparative growth and yield performance of foliar application Cropmax ( 0, 2.0, 3.0 and 5.0 ml L–1) . Data were collected on plant height, leaf per plant, branches per plant, length of root, leaf area, dry weight of shoot, dry weight of root, TDM, AGR, CGR and RGR, number of pod per plant, pod length, number of seed per pod, thousand seed weight, grain yield (t ha–1), straw yield (t ha–1), biological yield (t ha–1) and harvest index (%) etc.The experiment was laid out in a completely randomized block design (RCBD) with three replications. The collected data were analyzed statistically and means were adjudged by DMRT at 5% level of probability. The treatments Cropmax @ 3.0 ml L–1 as foliar application gave the highest performance in respect of all growth and yield parameters. Progressive Agriculture 29 (3): 239-247, 2018

An experiment was undertaken at Agricultural Botany Laboratory, Patuakhali Science and Technology, to screen out salt tolerant barley (Hordeum vulgare L.) genotypes. The evaluation was done based on germination percentage, shoot length, root length and shoot: root ratio. Five barley genotypes including BARI barley 2, BARI barley 3, BARI barley 4, BARI barley 5 and BARI barley 7 were used in the screening program. The barley genotypes were grown in eight levels NaCl solution like 0(Control), 20, 40, 60, 80, 100 and 120 mM. The present study shows that salinity reduced germination percentage of barley and the extent of reduction increased with the increase in the concentration of salinity in the growth medium. Shoot dry weight (1.40 mg), root dry weight (0.21 mg), shoot moisture content (80.0%), root elongation rate (1.81), vigor index (21.30), speed of germination (7.91) and root length (21.67 cm) were obtained from the variety BARI barley 4 with 80 mMNaCL (V3T4). Based on the growth attributes the genotypes BARI barley 7 and BARI barley 4 were found tolerant to salt stress as they grown up to 60 mM and 80 mMNaCl solution respectively. The genotypes BARI barley 4 was therefore selected to be grown in south coastal saline soil of Bangladesh. Progressive Agriculture 32 (1): 1-9, 2021
