Effect of varying levels of silicon and restricted irrigation on productivity of wheat (Triticum aestivum L.) under Bhal condition of Gujarat

Abstract

A field experiment was conducted during rabi season 2019-20 at Agricultural Research Station, Anand Agricultural University, Dhandhuka, Gujarat, to evaluate the effect of different irrigation and silicon levels on wheat productivity. Results from the experiment indicate that significantly superior data were recorded with two irrigation (I3) in case of plant height (75.85), effective tillers per plant (6.18), ear length (cm) (8.71), grains per ear (35.42), test weight (g) (46.29) and grain yield (3360 kg ha-1) over control (I1) and being at par with three irrigation (I4). While 75% anthesis (73.33) and physiological maturity days (108.33) found significantly superior with three irrigation (I4) over control (I1) and being at par with two irrigation (I3) 72.83 and 107, respectively. Amongst different levels of silicon, 150 kg ha-1 (S3) significantly increased yield and yield attributes i.e., plant height (72.24), effective tillers per plant (6.12), ear length (cm) (7.67), grains per ear (32.81), test weight (g) (46.17) and grain yield (3182 kg ha-1) as compare to control (S1) and being at par with three irrigation (S4). The percent increase in case grain yield with silicon 150 kg ha-1(S3) is 40.29 over control (S1). Alike, results further pointed out that 75% anthesis (71.25) and physiological maturity days (104.42) found significantly superior with silicon 200 kg ha-1(S4) over control (S1) and at par with silicon 150 kg ha-1(S3).
