Abstract
The productive efficiency of two guar varieties BR-2017 and BR-99 was studied with variable nitrogen and phosphorous levels including 0-0, 0-60, 15-60, 30-0, 30-30, 30-60, 30-90 and 45-60 NP kg ha-1 during two sowing seasons 2015 and 2016 at Agriculture Research Station, Bahawalpur. The results showed that BR-2017 performed better than the BR-99. Variable levels of nitrogen and phosphorous also enhanced the yield of guar. The results indicated that maximum average grain yield of guar 2544 kg ha-1 was recorded in BR-2017 with NP dosage of 30:60 kg ha-1 nitrogen and phosphorous that was non-significantly different (2458 kg ha-1 ) from NP level of 30:90 kg ha-1 recorded from same variety. Results indicated that ‘BR-2017’ was more receptive to fertilizer application than the BR99.
