dc.description.abstractA field experiment was conducted during summer season of the year 2003 at the College Agronomy Farm, Anand Agricultural University, Anand to study the "Influence of irrigation schedules (1W:CPE ratio) and bio-fertilizers on growth and yield of summer blackgram [Phaseolus mungo (L.) Hepper] under middle Gujarat conditions". The soil of the experimental plot was loamy sand in texture having good drainage, low in nitrogen, medium in available phosphorus and high in potash with pH 7.5 Twenty treatment combinations comprising four levels of irrigation schedules viz., control-irrigation at critical growth stages (lo), 0.5 IW:CPE ratio (I1), 0.7 IW:CPE ratio (b) and 0.9 IW:CPE ratio (I3) and five treatments of bio-fertilizer viz., control-no inoculation (Ro), FSB inoculation (R1), Phosphorus @ 40 kg ha-1 (R2), PSB + Phosphorus @ 40 kg ha-1 (R3) and PSB + Rhizobium inoculation (Rt) were evaluated in split plot design with four replications. The results indicated that the grain and dry fodder yield as well as most of the growth and yield attributes of summer blackgram were significantly influenced due to different irrigatipn schedules. The results further revealed that treatment I3 (0.9 IW:CPE ratio) recorded significantly higher av. plant height at 20, 40 and 60 DAS, av. number of pods per plant, av. number of grains per pod, test weight (1000- grain weight in g). Treatment I3 (0.9 IW:CPE ratio) secured the highest grain yield (1004.75 kg ha-1) and dry fodder yield (2366.43 kg ha-1) of summer blackgram. The grain and dry fodder yield increased under the same treatment was to the tune of 50.40 and 26.62 per cent, respectively over treatment Io (control-irrigation at critical growth stages). The consumptive use of water was increased with increase in IW:CPE ratio whereas, the water use efficiency and water expense efficiency were higher with lower IW:CPE ratio. The highest value of net realization (Rs. 13085) was recorded under treatment I3 (0.9 IW:CPE ratio), followed by treatment h (0.7 IW:CPE ratio) with net realization (Rs. 9611). The lowest value of net realization (Rs. 4034) was observed under treatment Io (control-irrigation at critical growth stages). The highest value of net ICBR (1:4.97) was observed under treatment I1 (0.5 IW:CPE ratio), followed by treatment I3 (0.9 IW:CPE ratio) with net ICBR of (1:4.45). The lowest net ICBR (1:4.11) was noticed under treatment I2 (0.7 IW:CPE ratio). Among the different treatments of bio-fertilizer, the treatment R4 (PSB + Rhizobiutn inoculation) resulted in the maximum growth and yield attributes and protein content which ultimately resulted in higher grain and dry fodder yield of summer blackgram. The treatment R4 (PSB + Rhizobium inoculation) secured significantly the highest grain yield (962.76 kg ha-1) and dry fodder yield (2182.88 kg ha-1). The grain and dry fodder yield increase under the same treatment was to the tune of 43.19 and 13.80 per cent respectively over treatment Ro (control-no inoculation). Significantly the highest protein content (23.98 %) was recorded due to treatment R4 (PSB + Rhizobium inoculation). Apart from this, the treatment PSB + Rhizobium inoculation (R4) secured the highest consumptive use of water, water use efficiency and water expense efficiency. The highest value of net realization (Rs. 15664) and net ICBR (1:242.67) were observed under the same treatment. During the course of investigation, interaction effect between irrigation schedules and different treatments of bio-fertilizer was not significant in respect of growth and yield attributes, yield and quality parameters of summer blackgram. For securing higher grain yield and net realization from summer blackgram crop cv. T-9 the crop should be irrigated at 0.9 IW:CPE ratio with 10 irrigations each at 50 mm depth. One common irrigation should be applied immediately after sowing, second six days after first and remaining irrigations should be applied at an interval of six to seven days. The seed should be dually inoculated with PSB and Rhizobium, each @ 2 kg ha-1 as seed treatment, for securing high grain yield and maximum net realization.en_US
