Abstract

A field experiment was conducted at Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, to study the influence of irrigation scheduling (IW:CPE ratios) and sulphur on yield and quality of <italic>rabi</italic> pigeonpea (<italic>Cajanus cajan</italic> L<italic>.</italic>) under middle Gujarat conditions during <italic>rabi</italic>, 2009-10 on loamy sand soil. Irrigation scheduling at 0.8 IW/CPE ratios (I<sub>3</sub>) resulted in significantly the highest grain yield (1677 kg ha<sup>−1</sup>), protein content (20.85 %) and significantly higher stover yield (4858 kg ha<sup>−1</sup>) and gave highest net monetary returns of Rs.37591 ha<sup>−1</sup> with maximum B:C ratio of 2.34. Application of sulphur @ 40 kg S ha<sup>−1</sup> (S<sub>2</sub>) recorded significantly the highest grain (1630 kg ha<sup>−1</sup>) and stover (4819 kg ha<sup>−1</sup>) yields. In case of protein content and economics, application of sulphur @ 40 kg S ha<sup>−1</sup> recorded significantly the highest protein content (21.03 %) and the highest net monetary returns of Rs.35000 ha<sup>−1</sup> with maximum B:C ratio of 2.19. Interaction effect between irrigation scheduling and sulphur levels on grain yield was highly significant. Irrigation scheduled at 0.8 IW/CPE ratio with the application of 40 kg S ha<sup>−1</sup> recorded significantly higher grain yield (1929 kg ha<sup>−1</sup>) , however, it was at par with the irrigation scheduled at 0.8 IW/CPE ratio with 20 kg S ha<sup>−1</sup>.
