Abstract

This experiment was conducted on a permanent layout at the west byde of BRRI farm, Gazipur during T. Aman 2019 to Boro 2021-22 to find out the suitable management practices for yield maximization of rice and soil health. Seven treatments in Randomized Complete Block (RCB) Design with three replications were imposed and each treatment was assigned in 5m × 4m sized plot. The treatments combinations were T1= Absolute Control (No nutrient supply), T2 = BRRI dose N-P-K-S@83-17-53-12 kg ha-1 in T. Aman and 138-21-75-21 kg ha-1 in Boro season, T3= Soil Test Based (STB) Fertilizer Dose N-P-K-S @ 67-10-40-10 kg ha-1 in T. Aman and 134-16-75-10 kg ha-1 in Boro, T4 = STB dose + 1 t ha-1 Cowdung, T5 = STB dose + 1 t ha-1 Poultry manure, T6 = STB dose + 1 t ha-1 Vermicompost and T7 = STB dose + 0.33 t ha-1 CD + 0.33 t ha-1 PM + 0.33 t ha-1 VC. Thirty-days old seedling of BRRI dhan87 in T. Aman and fourty-two days old seedling of BRRI dhan89 in Boro season were transplanted at 20 cm × 20 cm spacing in both seasons. All manures, soil and plant samples analysis were done by the help of soil Science Division BRRI, Gazipur. Initial soil (0-15 cm depth) properties were: soil texture, clay loam; pH, 6.94; organic Carbon, 1.59%; Nitrogen, 0.18%; Phosphorus, 21.88 ppm and Potassium, 0.19meq/100g soil. Thirty days old seedling of BRRI dhan87 in T. Aman and 42 days old seedling of BRRI dhan89 in Boro season were transplanted at 20cm x 20cm spacing. Grain yield, tiller number, panicle number, plant height and grain number were significantly affected by the different integrated nutrient management during both T. Aman and Boro season. Grain yield, tiller number, panicle number, plant height and grain number were significantly affected by the different nutrient management in both T. Aman and Boro season. Poultry manure related treatments and BRRI recommended dose performed better than the others in all the parameter except 1000-grain weight. On the other hand, Absolute Control (No nutrient supply) produced the lowest result. Every parameter, Poultry manure treatments have been performed the best. STB dose with one t ha-1 poultry manure is better for maximization of rice yield.

通过综合养分管理实现水稻（Oryza sativa）产量最大化

该试验于 2019 年天安节至 2021-22 年勃朗节期间在加济布尔 BRRI 农场西侧的永久性布局上进行，旨在找出实现水稻产量最大化和土壤健康的合适管理方法。采用随机完全区组（RCB）设计，共设七个处理，三个重复，每个处理分配在 5m × 4m 大小的地块中。处理组合为：T1= 绝对对照（无养分供应）；T2= BRRI 剂量 N-P-K-S@83-17-53-12 kg ha-1（天安季节）和 138-21-75-21 kg ha-1（波罗季节）；T3= 土壤测试（STB）肥料剂量 N-P-K-S@67-10-40-10 kg ha-1（天安季节）和 134-16-75-21 kg ha-1（波罗季节）。T4 = STB 剂量 + 1 吨/公顷-1 牛粪，T5 = STB 剂量 + 1 吨/公顷-1 禽粪，T6 = STB 剂量 + 1 吨/公顷-1 蛭石，T7 = STB 剂量 + 0.33 吨/公顷-1 CD + 0.33 吨/公顷-1 PM + 0.33 吨/公顷-1 VC。两季均以 20 厘米 × 20 厘米的株行距移栽了天安时 30 天大的 BRRI dhan87 幼苗和波罗时 42 天大的 BRRI dhan89 幼苗。所有肥料、土壤和植物样本的分析都是在加济布尔 BRRI 土壤科学部的帮助下完成的。初始土壤（0-15 厘米深）特性为：土壤质地为粘壤土；pH 值为 6.94；有机碳含量为 1.59%；氮含量为 0.18%；磷含量为 21.88 ppm；钾含量为 0.19meq/100g 土壤。以 20 厘米 x 20 厘米的株行距移栽了天安季节 30 天大的 BRRI dhan87 秧苗和波罗季节 42 天大的 BRRI dhan89 秧苗。安缦季和波罗季的谷物产量、分蘖数、圆锥花序数、株高和粒数均受到不同综合养分管理的显著影响。安缦季和波罗季的谷物产量、分蘖数、圆锥花序数、株高和谷粒数受不同养分管理的显著影响。除千粒重外，家禽粪便相关处理和 BRRI 推荐剂量在所有参数上的表现均优于其他处理。另一方面，绝对对照（不供应养分）的结果最低。在所有参数中，家禽粪肥处理的表现最好。添加 1 吨/公顷家禽粪便的 STB 剂量能更好地提高水稻产量。
