A field experiment was conducted during the wet seasons of 2013 and 2014 to evaluate the effect of three rice establishment methods: viz. puddled transplanted rice (PTR), system of rice intensification (SRI) and aerobic rice system (ARS), two cyanobacteria based inoculants, viz. Anabaena sp (CR1) + Providencia sp (PR3) consortium and Anabaena–Pseudomonas (An‐Ps) biofilm formulation, and zinc (Zn) fertilization on the rice yield, water productivity, and nutrient use efficiency. The yields of rough, brown and milled rice were highest in SRI, which was on par with PTR and both methods proved significantly superior to ARS in both years. The total water productivity of rough and brown rice in the first year was significantly higher in SRI. The SRI method saved 21.9% and 27.4% irrigation water over PTR, and savings in ARS were 37.4% and 50.8% in first and second year respectively, over PTR. The use of An‐Ps biofilm formulation along with 75% RDN improved the agronomic use efficiency of both nitrogenous and phosphatic fertilizers applied. On the basis of the present study, it can be concluded that SRI improved rice yields and water productivity; while involvement of An‐Ps biofilm formulation can be recommended for improved nutrient use efficiency.

通过改变作物种植方法、微生物接种和锌肥的应用来提高水稻的水和养分利用效率。

在 2013 年和 2014 年雨季进行了田间试验，以评估三种水稻种植方法的效果：泥插秧（PTR）、水稻强化系统（SRI）和需氧水稻系统（ARS），两种基于蓝藻的接种剂，即。鱼腥藻(CR1) +普罗维登斯(PR3) 联合体和鱼腥藻-假单胞菌(An-Ps) 生物膜配方以及锌 (Zn) 施肥对水稻产量、水分生产率和养分利用效率的影响。SRI 中的粗米、糙米和精米产量最高，与 PTR 相当，并且这两种方法在这两年中均明显优于 ARS。在SRI中，第一年糙米和糙米的总水分生产率明显更高。SRI 方法比 PTR 节省了 21.9% 和 27.4% 的灌溉水，ARS 第一年和第二年分别比 PTR 节省了 37.4% 和 50.8%。An-Ps 生物膜制剂与 75% RDN 的使用提高了氮肥和磷肥的农艺利用效率。根据本研究，可以得出结论：SRI 提高了水稻产量和水分生产率；同时建议使用 An-Ps 生物膜制剂来提高养分利用效率。
