ASHANUZZAMAN An experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, from October 2021 to April 2022 to study the effect of organic manure and N P fertilizer on boro rice's yield and seed quality of boro rice. The BRRI dhan28 was used as the test crop in this experiment. The experiment consists of 2 factors i.e., four level of organic manure. OM 0 : Without organic fertilizer (control), OM 1 : Cowdung @ 10 tha -1 , OM 2 : Vermicompost @ 3 tha -1 and OM 3 : Poultry manure @ 5 tha ; and four different N P fertilizer level F 0 : Without N P fertilizer, F 1 : 25% less than the recommended dose of N P fertilizer, F 2 : Recommended dose of N P fertilizer and F 3 : 25% Higher than the recommended dose of N P fertilizer. The experimental design was RCBD and treatments were replicated three times. The result revealed that among the organic manures, poultry manure was found best in respect of growth, yield, and seed quality parameters, this treatment produced the highest yield (4.90 tha -1 ), tallest plant (32.66, 50.95, 78.33, 94.75 and 99.30 cm) at 30, 50 70 90 DAT and at harvest, respectively; maximum tillers per plant for all sampling dates (8.90, 12.33, 13.10, 14.33 and 15.09) at 30, 50 70 90 DAT and at harvest, respectively and gave highest yield contributing parameters like effective tiller hill -1 (12.67), panicle length (21.90 cm), grain panicle (104.15) and 1000 grain weight (21.66 g). On the other hand, 25% Higher than recommended N P fertilizer dose gave the highest yield (4.50 tha -1 ). This dose also produced maximum plant height and tillers plant -1 for all growth stages, the highest number of grains panicle -1 (104.75), 1000 grain weight (21.67 g), and straw yield (5.33 tha ). Considering the interactions, Poultry manure @ 5 tha -1 (Om 3 ), 25% higher than the recommended dose of N P fertilizer (F 3 ), gave the highest grain yield (5.83 tha ). This interaction also gave the highest effective tiller hill -1 (14.70), panicle length (22.33 cm), and grain panicle -1 (6.26 tha -1 ). Regarding seed quality parameters, Poultry manure @ 5 tha -1 (Om 3 ) and 25% higher than the recommended dose of N P fertilizer (F 3 ) gave better performance. The study concluded that, poultry manure @ 5 tha -1 (Om 3 ) and 25% Higher than the recommended N P fertilizer (F 3 ) could be recommended for better yield and seed quality of BRRI dhan28.

Three planting methods viz. M 1 = Direct sowing of seed, M 2 = 1/3 cutting of root and M 3 = 2/3 cutting of root were comprised with plant spacings viz., S 1 = 30 cm × 20 cm, S 2 = 30 cm × 30 cm, S 3 = 30 cm × 40 cm. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Different planting methods showed significant variation for growth, yield contributing parameters, yield and quality parameters of radish. The planting method M 1 (Direct sowing of seed) showed significantly highest seed yield plant -1 (10.87 g) and seed yield ha -1 (1234.00 kg) compared to M 2 (1/3 cutting of root) and M 3 (2/3 cutting of root) treatment. M 1 (Direct sowing of seed) also showed the best quality seeds considering highest germination percentage (88.43%) and vigor index (1434.57) whereas M 3 (2/3 cutting of root) treatment gave the minimum results. Different plant spacing of radish showed significant variation for growth, yield contributing parameters, yield seed quality parameters. The highest seed yield ha -1 (1283.33 kg) was recorded from the plant spacing S 1 (30 cm × 20 cm) while the plant spacing S 3 (30 cm × 40 cm) spacing gave the significantly highest germination percentage (89.00%) and vigor index (1611.74). The treatment combination of M 1 S 3 gave the highest number of pods plant -1 (82.13), number of seeds pod -1 (6.31), dry weight plant -1 (153.70 g) and seed yield plant -1 (13.81 g) but the highest seed yield ha -1 (1386.00 kg) was recorded from the treatment combination of M 3 S 1 but the lowest seed yield ha -1 (841.90 kg) was recorded from M 3 S 3 . The treatment combination of M 3 S 1 gave the maximum germination percentage (90.40%) and vigor index (1722.12) whereas M 3 S 1 gave the minimum results. From the above results, it can be concluded that among the planting methods, M 1 (Direct sowing of seed) performed the best regarding growth, seed yield and seed quality. Considering plant spacing, S 1 (30 cm × 20 cm) performed the highest seed yield whereas S 3 (30 cm × 40 cm) was the best for quality seeds production.

The experiment was laid out in Randomized Complete Block Design (RCBD) with five different treatment viz: T 1 : Confidor 70WG (imidacloprid) @3g/kg of seed, T 2 : Bioneemplus 1EC (azadirachtin) @1.0 ml/L of water, T 3 : Neem seed kernel extract (azadirachtin) @50 g/L of water, T 4 : Tracer 45 SC (spinosad) @0.4 ml/L of water and T 5 : untreated control, for the management of aphid and tobacco cutworm of mustard with three replications for each treatment. Data on different parameters were recorded and significant variation was observed among different treatment. Experimental result showed that at early, mid and late stage of flowering and fruiting the highest number of aphid and cutworm was observed in T 5 treatment while the lowest number of aphid and cutworm was observed in T 4 treatment. In case of aphid at flowering fruiting stage the maximum number of healthy plant m -2 (28 and 24.67) and higher infestation reduction percentage (76.92 and 72.78 %) was observed in T 4 treatment. In the case of tobacco cutworm at the flowering and fruiting stages, the highest number of healthy plants per square meter (29.33 and 28.00) and the highest infestation reduction percentage (87.64and 76.92 %) was found in the T 4 treatment. In case of growth, yield contributing characters and yield of mustard, among different treatments the maximum plant height (106.35 cm), number branches plant (16.02), siliqua plant -1 (105.10), siliqua length (4.14 cm), seeds siliqua (26.87), 1000seed weight (4.02 g) and higher seed yield (1.77 t ha -1 -1 ) was obtained from T 4 treatment which gave (84.38 %) more yield comparable to control treatment. Based on the investigation of the above results, it may be concluded that among seed treating chemical and few botanicals for controlling mustard aphid and tobacco cutworm, spraying Tracer 45 SC @0.4 ml/L of water at 10-day intervals was the most effective among the management practices for controlling mustard aphid and tobacco cutworm.

The experiment was laid out in randomized complete block design (RCBD) with three replications and consisted of ten treatments i.e. T 1 = S 0 Zn 4 B 2 Kg ha -1 , T 2 = S 10 Zn 4 B 2 Kg ha ii -1 , T 3 = S 20 Zn 4 B 2 Kg ha Kg ha -1 , T 5 = S 20 Zn 0 B 2 Kg ha -1 , T 6 = S 20 Zn 2 B 2 Kg ha -1 , T 7 = S 20 Zn 6 -1 B = S 1 20 Zn 4 B 0 Kg ha -1 , T 9 = S 20 Zn 4 B 1 Kg ha -1 , T 10 = S 20 Zn 4 B 3 Kg ha -1 , T 11 , T 2 = S . Experimental results revealed that different doses of sulphur, zinc and boron fertilizers application significantly influenced the growth and seed yield of SAU yellow cherry tomato. In case of different treatments, the height number of flowers per cluster (62.91), number of flowers per plant (568.77), number of fruits per cluster (77.11), total number of fruits per plant (499.44), individual fruit weight (12.51 g), height fruit yield per plant (4.58 kg), fruit yield per plot (27.49 kg), fruit yield per hectare (84.84 t), seeds per tomato fruit (98.22), seed yield per plant (19.12 g), seed yield per plot (114.64 kg), seed yield per hectare (353.83 kg), seed germination (90.44 %) and vogority index (3014.20) were observed in T 10 (S 20 Zn 4 B 3 4 = S Kg ha 0 Kg ha ) treatment whereas the corresponding lowest value were observed in T treatment.. Therefore, it was suggested that cultivation of cherry tomato through application of S 11 Kg ha -1 (T treatment) would help to influenced plant growth and increase its ability to enhanced better seed yield production of SAU Yellow Cherry tomato.
