Abstract

An experiment was carried out at Sher-e-Bangla Agricultural University, Dhaka in the tenure of from January to March, 2018 to evaluate the effect of alternate furrow irrigation and varying fertilizer management on the yield performance of baby corn. Two irrigation methods viz. IC (Conventional irrigation) and IA (Alternate furrow irrigation); and six fertilizer managements viz. F0 (No fertilizer application; control), F1 (Recommended doses of fertilizer), F2 (125% of recommended doses of fertilizer), F3 (75% of the recommended doses of fertilizer), F4 (50% of the recommended doses of fertilizer) and F5 (25% of recommended doses of fertilizer) were tested. Both the individual and that of the combined effects of the treatments varied significantly in respect of most of the parameters studied. In respect of combined effect of irrigation and fertilizer, the highest cob diameter (7.03 cm), cob length (18.00 cm), fresh single cob weight with husk at harvest (46.07 g), dry weight of single cob without husk (7.74 g) and fresh cob yield without husk (2.40 t ha-1) were observed from the combination treatment IAF1 whereas, the respective lowest values were found from treatment combination of ICF0.

Abstract

The present experiment was undertaken with the aims to investigate the response of potassium fertilizer and mulches on growth and yield of potato in the field condition during the period from November 2017 to March 2018 at Horticultural farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. The variety “Diamant” was used as a test crop. Four levels of potassic fertilizer (KCl) viz. K0: (Control), K1: 110 kg ha-1, K2: 140 kg ha-1, K3: 170 kg ha-1 and three types of mulches viz. M0: (Control), M1: Straw, M2: Black polythene were used for the present study. The experiment was laid out in Randomized Block Design (RCBD) with three replications. Different potassium level showed significant influence on most of the parameters and the treatment. The highest yield (27.20 t ha-1) of potato was obtained in K2 treatment whereas the lowest (12.25 t ha-1) was obtained from K0. Considering the different mulches, the highest yield (24.57 t ha-1) of potato was obtained in M1 and the lowest (17.68 t ha-1) was obtained from the M0 treatment. In terms of the combined effect of potassium and mulching, most of the studied parameters were influenced significantly. The highest yield (31.75 t ha-1) was recorded from the combination treatment of K2M1 whereas the lowest yield (9.74 t ha-1) was found in the combination treatment K0M0. Hence, we summarized that 140 kg ha-1 potassium fertilizer with straw mulch gave the maximum output in terms of yield compared with other treatments.

Abstract

The study was conducted at breeder seed division of Bangladesh Jute Research Institute, Dhaka from September 2018 to January 2019 to determine prestorage hardening effects on chemical composition of jute seed. The experiment was conducted in Complete Randomized Design (CRD) with four replications. The highest total soluble protein (210.6 and 185.2 mg g-1) were obtained in control treatment, while the lowest were (204.3 and 182.0 mg g-1) in treated seeds of capsularis and olitorius seeds, respectively. The highest total free amino acids (32.69 mg g-1 and 24.80 mg g-1) were estimated in treated and the lowest (30.11 mg g -1 and 23.30 mg g -1) from control treatment in capsularis and olitorius seeds, respectively. Total soluble sugar was statistically identical both in treated and control treatment though total soluble sugar was always higher in capsularis than in olitorius seed. Presence of soluble sugar in seed has great implication on seed quality as there was positive correlation between the total soluble sugar content and germination percentage of jute seed which indicated that higher the amount of soluble sugar, higher the germination percentage. Oil content and ash content of jute seed were not significantly influenced by hardening treatments. Among two species of jute higher oil content was observed in olitorius seed than in capsularis seed. On the other hand, ash content was always higher in capsularis than in olitorius.

Abstract

The effect of chemically disinfected wheat straw on the proximate composition and mineral content of oyster mushrooms (Pleurotus ostreatus) was investigated. Different treatment levels were used in combination with different times (12, 18 and 24 hours) and doses of Formalin (250, 500 or 750 ppm) and Bavistin (75 ppm), and regulation was compared. The highest production in terms of protein in percent (25.71) was obtained in wheat straw processed with Formalin (500 ppm) + Bavistin (75 ppm) for 18 hours. Pleurotus ostreatus grown on wheat straw treated with Formalin (750 ppm) + Bavistin (75 ppm) for 18 hours yielded the highest percentage of crude fiber (21.40), Ca (22.15 mg/100 gm) and Zn (15.10mg/100 gm) content. So, sterilizing wheat straw with Formalin (750 ppm) + Bavistin (75 ppm) for 18 hours may be an economically effective treatment for the nearest compression and the higher mineral oyster mushroom content.

Abstract
The experiment was conducted at the Agronomy Farm of Sher-e-Bangla Agricultural University, Dhaka during November 2017 to April 2018 to examine the varietal performances of white maize as influenced by different level of herbicides. The experiment comprised two varieties viz. PSC-121 and Yangnuo-3000 designed as V1 and V2 respectively combined with six weed control measures viz. T0 = No weeding, T1= Carfentrazone + Isoproturon 500g @ 1.5 g ha-1 (Affinity 50.75% WP), T2= Carfentrazone + Isoproturon 500g @ 2.0 g ha-1 (Affinity 50.75% WP), T3= Pendimethalin @ 2.0 l ha-1 (Panida 50EC), T4= Pendimethalin @ 3.0 l ha-1 (Panida 50EC) and T5= One hand weeding at 45 DAS. The experiment was laid out in split plot design with three replications. The highest plant height, leaf area index, crop growth rate, leaf area duration, 100-seed weight (35.67 g), grains cob-1 (426.5), grain yield (8.817 t ha-1), stover yield (7.35 t ha-1) and biological yield (16.17 t ha-1), WCE (74.24%), the lowest weed density (85.92 no. m-2) and biomass (95.056 g m-2) were achieved from T4. On the other hand, all the parameters studied were found lowest with T0. In case of variety, PSC-121 showed the superior performance in terms of weed density, weed biomass, weed control efficiency, plant height, leaf area index, crop growth rate, leaf area duration, 100-seed weight (33.89 g), number of grains cob-1 (412.0), grain yield (7.75 t ha-1), stover yield (6.12 t ha-1) and biological yield (13.87 t ha-1) over YANGNUO-3000. However, in terms of interaction of weed control measures and variety T4V1 showed the superior findings regarding weed density, weed biomass, weed control efficiency, plant height, leaf area index, leaf area duration and crop growth rate. This combination treatment also showed the highest values in 100-seed weight (40.33 g), number of grains cob-1 (445.6), grain yield (9.63 t ha-1) and biological yield (16.72 t ha-1) although in some instances these values were not significantly higher than T4V2. The lowest performances in respect of all the parameters studied were recorded from T0V2 which was in some cases was statistically at par when compared with T0V1.

Abstract
The experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka to evaluate the effect of phosphorus and potassium on the growth and yield of carrot during the period from November 2013 to March 2014. The two-factor experiment was laid out in a Randomized Complete Block Design with three replications. The experiment consisted of four different levels of phosphorus, viz. P0 (control), P1 (65 kg), P2 (80 kg), and P3 (95 kg) P2O5 ha-1 respectively and four levels of potassium, viz. K0 (control), K1 (150 kg), K2 (175 kg) and K3 (200 kg) K2O ha-1 respectively. Application of phosphorus and potassium influenced independently and also in combination on the growth and yield of carrot. The highest root length (16.27 cm), dry matter content of root (9.31%), gross yield (38.37t ha-1) and marketable yield (36.03t ha-1) was obtained from P3 (95 kg P2O5t ha-1) whereas, the control treatment gave the lowest results. On the other hand, treatment K3 (200 kg K2O ha-1) performed the highest root length (16.78 cm), dry matter content of root (9.35%), gross yield (42.22t ha-1) and marketable yield (38.33t ha-1) and the control treatment showed the lowest results. Considering the combined effect of phosphorus and potassium, P3K3 (95 kg P2O5 ha-1 with 200 kg K2O ha-1) produced the highest gross yield (40.58 t ha-1) and marketable yield (37.14 t ha-1). The lowest gross (24.00 t ha-1) and marketable yield (22.24 t ha-1) was produced by the control treatments combination (P0K0).
