Abstract: A field experiment was conducted during rabi season of 2004 at College Farm, Navsari Agricultural University, Navsari to study the "Response of rabi greengram [Vigna radiata (L.)l to irrigation, phosphorus and bio-fertilizer under South Gujarat condition." The soil of the experimental field was clay in texture having medium to poor drainage, low in total nitrogen (0.043 per cent), medium in phosphorus (32.35 kg ha'l) and fairly rich in potash (352.0 kg ha'l) with 7.8 pH. Eighteen trea~ment combinations consisting of three levels of irrigation viz., 0.3 IW/CPE ratio (Id, 0.5 IW/CPE ratio (h) and 0.7 IW/CPE ratio (13) with 6 cm depth of irrigation at each irrigation, three levels of phosphorus viz.: 20 kg P20 S ha'i (Pd, 40 kg' P20 5 ha'i (P2) and 60 kg P205 ha'i (P3) and two levels of bio-fertilizer namely control (Bo) and PSB inoculation (B 1) were tried in a factorial randomized block design with three replications. Seed and stover yields as well as most of the growth and yield attributes, quality of greengram seed, nutrients (N and P) content and uptake by seed, stover as well as total were significantly influenced by irrigation levels. In most of the character, treatment 0.7 IW/CPE ratio (I,) showed its superiority over treatment 0.3 IW/CPE ratio (Ill. Irrigating the crop at an IW/CPE ratio of 0.7 (I,) recorded significantly the highest seed (1045.6 kg ha· 1 ) and stover (2110.6 kg ha· 1 ) yields of greengram. These were 38.43 and 20.04 per cent higher over 0.3 (Ill and 0.5 IW/CPE (12) ratio, respectively. The consumptive use of water was increased with increase in levels of irrigation (I,) whereas consumptive water use efficiency was recorded higher with 0.3 IW/CPE ratio (Id. The highest net return (Rs.18435 ha· 1 ) with BCR value (5.01) was obtained under treatment 0.7 IW/CPE ratio (13). Among the levels of phosphorus, the highest level of 60 kg P20 S ha· 1 (P 3) out rightly dominated and established its superiority in respect to almost all growth and yield attributes. Application of 60 kg P20 S ha· 1 (P,) produced significantly the highest seed (1028.9 kg ha· 1 ) and stover (\978.5 kg ha· 1 ) yields. The per cent increase in seed yield with 60 kg P20 S ha· 1 (P3) were 17.23 and 34.43 per cent over treatment of 40 kg P20S ha· 1 (P2) and 20 kg P20 S ha· 1 (Pd, respectively. Crop fertilized with 60 kg P20 S ha· 1 (P3) recorded significantly higher protein content in seed as compared to rest of the lower levels. Similarly, 60 kg P20 S ha· 1 (P3) also recorded the highest nutrients (N and P) content and uptake by seed, stover and its total. The highest
