Abstract: A field experiment was carried out at Research Farm College of Horticulture, Pendri, Rajnandgaon, CG during Kharif 2015-16. The study was conducted for yield maximization of rice varieties and various management practices under moisture stress conditions. The treatments comprised six Management practices viz. M1- RDF + Sequential application of herbicide; M2- RDF + Integrated weed management (Pre-emergence herbicide f.b. mechanical weeding to act as weed control as well as soil mulch), M3-RDF+2.5 t/ha FYM in row placement + Integrated weed management, M4-RDF+ Foliar application of hydrated lime at 60-65 days + Integrated weed management, M5-RDF+ 2.5 t ha-1 FYM in row placement + Foliar application of hydrated lime at 60-65 days+ Integrated weed management, M6-125% RDF+ 2.5 t ha-1 FYM in row placement + Foliar application of hydrated lime at 60-65 days+ Integrated weed management as main plot and four varieties viz. V1- Indira Barani Dhan-1, V2- R-RF-75, V3-Indira Aerobic-1, V4-IR-64 (Drought) as sub plot with three replications. The data revealed that treatment M6 was recorded the highest grain yield (40.04 q/ha). However, in case of minimum yield was recorded treatment M1 (31.24 q ha-1). In concerning with varieties R – RF- 75 was noted the highest yield (55.15 kg/ha). However, the lowest yield was recorded treatment v1 (27.8 q ha-1). From the experiment, varieties R – RF- 75 was recorded the highest grain yield in moisture stress condition and without supplementary irrigation. It was statistically at par with other treatments. Among different varieties of V4 (R – RF- 75) fetched maximum net profit (Rs. 49344 ha-1) and B: C ratio (2.86) while V1 (Indira Barani Dhan-1) variety could bring lowest in net profit and B: C ratio. Among different Management practices @ M6 recorded highest net return (36391) and highest B: C ratio was obtained 2.37.
