There were 12 treatment combinations with Four main plot treatments viz. conventional tillage (CT), minimum tillage (MT), zero tillage (ZT) and FIRBS; and three sub plot treatments i.e., I1: CRI+IW:CPE=0.90, I2: CRI+IW:CPE=0.75 and I3: CRI+IW:CPE=0.60 for wheat and I1: IW:CPE=0.80, I2: IW:CPE=0.70 and I3: IW:CPE=0.60 for cluster bean. FIRBS (bed) planting wheat resulted in significantly higher growth and yield parameters during 2012- 13 and 2013-14 crop seasons compared to CT and MT but the difference between FIRBS and ZT was not marked. Irrigation applied at CRI+IW/CPE=0.90 produced significantly higher growth parameters and yield parameters during both the crop seasons as compared to other irrigation schedules. FIRBS (bed) planted wheat produced significantly higher grain yield of wheat i.e., 5165 kg ha-1 during 2012-13 and 5508 kg ha-1 during 2013-14 as well as pooled grain yield of 5337 kg ha-1 as compared to CT and MT but the difference between FIRBS and ZT was at par with each other. Application of irrigation at CRI+IW/CPE=0.90 (4945 kg ha-1) during 2012-13 and during 2013-14 (5299 kg ha-1) as well as on pooled basis (5122 kg ha-1) as compared to other irrigation schedules. In the year, net returns (` 40452 ha-1 during 2012-13 and ` 49668 ha- 1 during 2013-14) and B:C (1.92 and 2.06, respectively) were significantly higher with ZT compared to other techniques. The total consumptive water by the wheat crop was 12% and 9% lower under FIRBS during 2012-13 and 2013-14 compared to CT. The total water use was around 8% and 9% lower under CRI+IW/CPE=0.75 compared to CRI+IW/CPE=0.90 during 2012-13 and 2013-14, respectively. Highest WUE was obtained with FIRBS (144.6 and 155.4 kg ha-cm-1) compared to other crop establishment techniques during both the crop seasons, respectively. Growth and yield parameters of cluster bean were significantly highest with FIRBS than ZT and MT during 2013 and 2014 seasons. Seed yield of cluster bean was significantly higher in FIRBS i.e., 900 and 471 kg ha-1 during 2013 and 2014, respectively compared to ZT, MT and CT. Net returns were significantly higher with FIRBS planting i.e., ` 20148 ha-1 during 2013 and ` 3183 ha-1 during 2014 as well as B:C i.e., 1.85 in 2013 and 1.13 in 2014 compared to other crop establishment. FIRBS (bed) planted wheat-cluster bean produced significantly higher WEY of 8233 and 7356 kg ha-1 as well as system net returns i.e., ` 60353 and ` 49741 ha-1 during 2012-13 and 2013-14, respectively compared to other crop establishment techniques. The WUE of wheat-cluster bean system was found to be highest (88.3 and 81.3 kg ha-cm-1) with FIRBS (bed) planting during 2012-13 and 2013-14, respectively than other crop establishment techniques.enirrigation, crops, wheats, yields, planting, developmental stages, irrigation scheduling, tillage, beans, seasonsThesis
