A study was carried out to establish crop arrangement for sweet gourd and cauliflower intercropping systems. The experiment was carried out during two consecutive years of 2019-20 and 2020-21 to identify the appropriate cauliflower population for intercropping with sweet gourd for increased production and profitability. Seven treatments viz. T1= Sole Sweet gourd (2 m × 2 m), T2=100% Sweet gourd + 3 rows cauliflower 37.5% (60 cm × 50 cm), T3=100% Sweet gourd + 3 rows cauliflower 23% (60 cm × 80 cm), T4=100% Sweet gourd + 4 rows cauliflower 50% (50 cm × 50 cm), T5=100% Sweet gourd + 4 rows cauliflower 31% (50 cm × 80 cm), T6=100% Sweet gourd + 5 rows cauliflower 31% (40 cm × 100 cm) and T7=Sole Cauliflower (50 cm × 50 cm). The maximum sweet gourd equivalent yield (SGEY) 34.83 t ha-1 was obtained from T4. The maximum gross return (Tk. 278640 ha-1), gross margin (Tk. 180384 ha-1), BCR (2.85) and LER (1.40) were also observed from T4 and the lowest in sole cauliflower (T7). The overall results revealed that among the intercrop combinations 100% Sweet gourd+4 rows cauliflower 50% (50 cm × 50 cm) (T4) followed by 100% Sweet gourd + 3 rows cauliflower 37.5% (60 cm × 50 cm) (T2) combinations could be profitable combinations for cauliflower with sweet gourd intercropping system. \u0000Bangladesh Agron.

Six treatment combinations viz. T1= 100% RDCF of chilli + 0% RDCF of garlic, T2= 100% RDCF of chilli +10% RDCF of garlic, T3= 100% RDCF of chilli + 20% RDCF of garlic, T4= 100% RDCF of chilli +30% RDCF of garlic, T5= 100% RDCF of chilli +40% RDCF of garlic and T6= 100% RDCF of chilli +50% RDCF of garlic were tested. The experiment was laid out in randomized complete block design with 3 replications. Both chilli and garlic characters significantly influenced by different treatment combinations. The maximum yield of chilli (10.12 and 9.10 t ha-1 at Gazipur and Noakhali, respectively) and garlic (3.70 and 3.55 t ha-1 at Gazipur and Noakhali, respectively) were obtained from T6 treatments which were statistically similar with T5 treatment. Chilli equivalent yield progressively increased with the increase of inorganic fertilizers. The results showed that T6 provided the highest CEY (17.52 and 16.18 t ha-1 at Gazipur and Noakhali, respectively) followed by T5 (17.47 and 16.14 t ha-1 at Gazipur and Noakhali, respectively). The highest gross margin (Tk. 339755 ha-1 and Tk 310198. ha-1at Gazipur and Noakhali, respectively) as well as BCR (4.50 and 4.32 at Gazipur and Noakhali, respectively) were obtained from T5 treatment while the lowest net return (Tk. 266661 ha- 1 and Tk. 242264 ha-1at Gazipur and Noakhali, respectively) as well as BCR (3.92 and 3.76 at Gazipur and Noakhali, respectively) were observed from T1 treatment.

Treatments were: T1 = 2 rows spinach (50%) in between two rows of brinjal (100%), T2 = 3 rows Spinach (75%) in between two rows of brinjal (100%), T3 = 2 rows red amaranth (50%) in between two rows of brinjal (100%), T4 = 3 rows red amaranth (75%) in between two rows of brinjal (100%), T5 = Sole brinjal ( 80 cm × 60 cm), T6 = Sole spinach (Line to line 20 cm) and T7 = Sole red amaranth (Line to line 20 cm) were used in the study.

Two varieties (viz; Isd 38 and Isd 39) and five planting datesfrommid-November to mid-Marchwere laid out in a Factorial Randomized Complete Block (RCB) design with three replications. Among the varieties, there was no significant difference; however Isd 38 performed better than Isd 39 in all aspect of yield contributing characters. Growth characters viz., tillers and millable cane stalks were significantly influenced by different planting dates. The highest germination (72.17%), tiller (111.03×103 ha-1), millable cane (91.12×103 ha-1), pol % cane (14.91%)and cane yield (75.47 t ha-1) were obtained from mid- November planting and gradually decreased with the advancement of planting times where all the lowest values were recorded from mid-March planting.

Experimental results revealed that deep placement of NPK briquette (2 x 2.4 g) increased rice grain yield about 10 % and it saves 51, 9 and 20 kg NPK ha-1 than BRRI fertilizer recommended rate in Boro season. Similarly, NPK briquette (1 x 3.4 g) produced 28 and 18% more rice grain yield than BRRI fertilizer recommended rate with a savings of 29 kg N and 7 kg K ha-1 in T. Aus and T.

Undiscounted benefit cost ratio (BCR) was 1.44, 2.40 and 3.20 for Boro, T. Aus and T. Aman, respectively when comparing at the same rates of N application. Thus, use of NPK briquette over urea broadcast and incorporation was economically viable and efficient for rice cultivation.
