dc.description.abstractAn experiment was conducted at the College Agronomy Farm, Gujarat Agricultural University, Anand Campus, Anand on loamy sandy soil during summer season of the year 1990-91. Four treatments comprising of three IW/CPE ratios (IW = 4 cm) of sprinkler method of irrigation viz., 0.45, 0.60 and 0.75, and one surface method of irrigation (IW = 6 cm) were laid out in completely randomised design with four repeatitions. The results revealed that irrigating the crop at 0.75 IW/CPE ratio through sprinkler method produced significantly the highest pod yield (2497 kg/ha) over rest of the treatments; and gave the highest net return (Rs. 15015/ha) and CBR (1 : 2.29) with net ICBR of 1 : 1.68. The increasing trend was observed in respect of pod and haulm yields as the IW/CPE ratio of sprinkler method increased. Surface method of irrigation surpassed all the sprinkler IW/CPE ratios and gave significantly the highest haulm yield (6184 kg/ha). The differences in growth characters viz., plant height, leaf area index, dry matter per plant, days to 50 per cent flower and days to maturity were found significant and almost remained higher under surface (I4) method of irrigation. Similarly, the yield attributes viz., number and weight of pods per plant, number of kernels per pod, shelling percentage and test weight were found significantly higher with 0.75 IW/CPE of sprinkler method of irrigation than lower IW/CPE ratio (I1) of sprinkler irrigation and surface method of irrigation. The different irrigation schedules had no any significant influence on oil and protein content of kernels. While, the harvest index was found significantly higher with 0.60 IW/CPE ratio of sprinkler method of irrigation. Though the consumptive use of water was higher under surface method of irrigation, water expense and water use efficiency (kg/ha) were found to be higher with all the sprinkler ratios than surface method of irrigation. The results of the present investigation, thus, indicated that potential production and profit from summer groundnut cv, CC-2 under middle Gujarat condition were secured by irrigating the crop at 0.75 IW:CPE ratio (I3) through sprinkler method of irrigation which gave the highest net realization as well as CBR and net ICBR.en_US
