Field experiments were carried out in the Agronomy field of BARI, Joydebpur, RARS, Jamalpur and RARS, Ishurdi during two consecutive kharif seasons of 2012 and 2013 to determine the suitable plant spacing and optimum fertilizer dose for higher yield of mukhikachu. Three levels of spacing viz., 60 cm x 60 cm, 60 cm x 45 cm and 60 cm x 30 cm and three levels of fertilizer dose viz., recommended dose (3000-96-27-81-18 kg ha-1 of CD-N-P-K-S), 25% less than the recommended dose and 25% higher than the recommended dose were used as treatment variables. The experiments were laid out in factorial randomized complete block design with three replications. Results revealed that the closer spacing (60 cm x 30 cm) in combination with 25% higher than the recommended fertilizer dose gave the maximum edible yield of mukhikachu (two years average) at all locations (20.04 t ha-1, 20.75 t ha-1 and 16.63 t ha-1 at Joydebpur, Jamalpur and Ishurdi, respectively). The wider spacing (60 cm x 60 cm) coupled with 25% less than the recommended fertilizer dose produced the lowest yield (two years average). The maximum benefit- cost ratio (two years average) was obtained from the combination of the recommended fertilizer dose and 60 cm x 30 cm spacing, that were 2.93 at Joydebpur and 3.42 at Ishurdi, while at Jamalpur the maximum benefit-cost ratio (two years average) was found maximum from 60 cm x 30 cm spacing with 25% higher than the recommended fertilizer dose (3.12).Bangladesh J.

A field experiment was carried out to study the “Effects of different maize–soybean intercropping patterns on yield attributes, yield and B: C ratio” at the Agricultural Research Farm, Bhagwant University, Ajmer. Treatment consists of Sole maize (60x20 cm), Sole Soyabean (30x10 cm), Maize-Soybean (1:1) (60X20 cm), Maize-Soybean (1:1) (75X20 cm), Maize-Soybean (1:1) (90X20 cm), Maize-Soybean (1:2) (90X20 cm) and Maize-Soybean (2:6) (Paired row 45/180 cm). There were four replicated blocks and plot sizes measuring 7 m x 4.5 m laid out in a randomized complete block design (RCBD). Results of the experiment showed that the maize-soybean intercropping patterns had significant effect on maize stover and grain yields. Sole maize recorded significantly higher yield than intercropped maize under varying geometry and row proportion. However, it was at par with maize intercropped with soybean in 1:1 row proportion with 60 x 20 cm .The intercropping patterns affected significantly the PAR intercepted and the leaf area index. The soybean sole crop intercepted significantly more light and leaf area index (LAI) than all other treatments and/or crop. Further,, the yield of sole soybean was significantly superior over other intercropped treatments. The highest benefit cost ratio revealed that higher return per unit money invested for inputs used for raising crops. The highest B: C ratio was recorded with maize + soybean in 2:6 paired row (3.57) intercropping system. The least B: C ratio was recorded in sole soybean (2.45).

A field experiment was conducted at S.V. Agricultural College farm (ANGRAU), Tirupati, India during rabi, 2009-10. The experiment was consisted of five system treatments (sole maize at 60 x 20 cm sowing, sole maize in skipped row sowing, maize in skipped row + greengram, maize in skipped row + blackgram and maize in skipped row + cluster bean) and three nitrogen doses (100, 75 and 50% recommended dose of nitrogen). The treatment combinations were laid out in factorial randomized block design with three replications. Yield attributes and grain yield of maize were maximum with sole maize at 60x20cm spacing but at par with maize + cluster bean, maize + blackgram and maize + greengram intercropping system. The lowest parameters were observed with sole maize sown in skipped rows. All the parameters were maximum with the application of 100% recommended dose of nitrogen to maize, but comparable with that of 75%. The maize equivalent yield, land equivalent ratio and benefit cost ratio were higher with maize + cluster bean intercropping as compared to other treatments. The result revealed that among the different maize intercropping systems tested, maize in skipped rows + cluster bean with 75% recommended dose of nitrogen to maize was found economically profitable.SAARC J.

A field experiment was conducted at Punjab Agricultural University, Regional Research Station, Gurdaspur (Punjab) during kharif 2016-17, to study the effect of split application of potassium on yield and yield attributes of soybean. The experiment was conducted in randomized complete block design with seven treatments applied at sowing and as split application of potassiumT1: Recommended fertilizer dose (12.5 kg N, 32 kg P2O5and no potassium application) , T2: 15 kg K2O ha-1(at sowing), T3: 30 kg K2O ha-1(at sowing), T4:60 kg K2O ha-1(at sowing), T5: 7.5 kg K2O ha-1 (at sowing) + 7.5 kg K2O ha-1 (at flowering), T6: 15 kg K2O ha-1(at sowing) +15 kg K2O ha-1(at flowering), T7: 30 kg K2O ha-1(at sowing) +30 kg K2O ha-1(at flowering). Results revealed that significantly higher grain yield (25.2 q ha-1) was obtained in T7 (30 kg K2O ha-1 (at sowing) + 30 kg K2O ha-1 (at flowering) as compared to all other treatments but it was statistically at par with the split application of potassium @ 15 kg K2O ha-1 (at sowing) + 15 kg K2O ha-1 (at flowering) (T6) with grain yield of (22.6 q ha-1). Split application of potassium significantly increased soybean grain yield over the basal application with highest benefit cost ratio (7.1). Among the split application of potassium, grain yield of soybean was increased significantly by 15.6 % in T7 treatment over T5. Split application of potassium was more beneficial than applying full dose of potassium at the time of sowing due to higher number of pods and pod weight plant-1.

A field trial on soil test based (STB) fertilizer doses was conducted during the year of 2017-2018 and 2018-2019 in Jashore region (AEZ-11) to find out the most suitable fertilizer doses for four crop based cropping pattern considering the agronomic feasibility and economic return of the system. The experiment consisted of eight different treatments viz. T1: 100% NPKSZnB (STB), T2: T1 + 25% N, T3: T1 + 25% NP, T4: T1 + 25% NK, T5:T1 + 25% PK, T6:T1 + 25% NPK, T7: 75% of T1, T8: Native fertility. Randomized complete block design (RCBD) with three replications was followed. Data revealed that seed yield of mustard was remarkably influenced by fertilizer treatments while grain yield of other components of the cropping system was not affected significantly by the treatments except control or native fertility. It was observed that 25% more NPK over 100% STB dose provided the highest yield of all the component crops. The highest rice equivalent yield (3.34 t ha-1) was recorded from T6 and the lowest (1.88 t ha-1) from T8 treatment. Maximum gross return (Tk. 420000/ha) and marginal benefit cost ratio (4.08) were also obtained from T6 treatment. So, 25% NPK+ 100% STB dose of fertilizer could be followed for productive and remunerative rice based cropping system Mustard-Boro-T. Aus-T.Aman in AEZ-11. Bangladesh Agron. J. 2021, 24(1): 109-117

The experiment was conducted in medium highland at Dacope, Khulna during rabi season of 2010-11. The aim of the study was to observe the effect of integrated use of bio-slurry along with inorganic fertilizer on the performance of water melon grown in AEZ 13. The experiment was laid out in a randomized complete block design with four replications. Three fertilizer doses viz. T1 : Soil test based inorganic fertilizer dose for high yield goal (HYG), T2 : Cowdung bio-slurry @ 5t/ha + IPNS basis inorganic fertilizer dose for high yield goal and T3 : Farmers’ practice (average of 20 farmers surveyed) were taken as treatment. Results showed that yield and yield contributing characters of water melon were significantly influenced by the treatments. The highest fruit yield (44.50 t/ha) was recorded in cowdung bio-slurry@ 5 t/ha + IPNS basis inorganic fertilizer dose (T2) followed by T1 (40.27 t/ha). The lowest yield (35.20 t/ha) was obtained from farmers’ practice. Economic analysis also revealed that the gross return (Tk. 534000.00/ha) and gross margin (Tk. 427515.00/ha) were higher in T2. Benefit-cost ratio (BCR) was also higher in T2 (5.01).DOI: http://dx.doi.org/10.3329/jesnr.v6i2.22097 J. Environ. Sci. & Natural Resources, 6(2): 61-63 2013
