EFFECT OF PHOSPHORUS ON GROWTH AND NODULE FORMATION OF INDIGO PLANT UNDER OLD HYMALYAN PIEDMONT FIELD CONDITION (Pages : 21 - 24)

An experiment was conducted at the soil science field laboratory Hajee Mohammad Danesh Science and Technology University, Dinajpur, during the period from March 28 to 23 October 2005 to evaluate the effect of phosphorus (P) on growth and nodule formation of indigo plant under Old Himalayans Piedmont field condition. The highest shoot length, , shoot dry weight, root dry weight, nodules plant -1 , number of effective nodules, dry weight of nodules plant -1 , 1000 seed weight, grain yield were obtained from the treatment 50kg P2O5. The tallest shoot of 63.60 cm, 140.20 cm and 241.5 cm were recorded from the treatment 50kg P2O5 at 45 DAS, 75 DAS and at harvest, respectively. The maximum dry matter of shoot 3.14, 14.74 and 71.33 g plant -1 , were recorded in the treatment 50kg P2O5 at 45 DAS, 75 DAS and at harvest, respectively. The maximum dry matter yield of root 0.56 g, 1.37 g and 4.31 g plant -1 were obtained to the treatment 50kg P2O5 at 45 DAS, 75 DAS and at harvest, respectively. The control gave the minimum dry matter yield of shoot and root. The results showed that the highest number of nodule of 12.8 and 24.6 were recorded to the treatment 50kg P2O5 at 45 DAS and 75 DAS, respectively. Download
