EFFECT OF NITROGEN-PHOSPHORUS AND IRRIGATION SCHEDULES ON THE GROWTH AND YIELD OF MUSTARD (BRASSICA JUNCEA L.)

Abstract

To investigate the impact of Nitrogen and Phosphorus, as well as different irrigation schedules, on the growth and yield of the Mehran Raya variety of mustard, The results showed that the F_{3 =} 120-60 kg/ha produced population plant( 31.78 m²), height of plant(181.09 cm), branch plant^-1 (9.24),pods/plant(832.87) seeds pod^-1 (15.26), seed index (1000 seeds wt. 17.11 g), and seed yield (2407.67 kg ha^-1). while theF₁(control) results showed minimum plant population of(8.11m²), height of plant (126.98cm), branch plant^-1(4.92), pods plant^-1(471.49) seeds pod^-1 (5.07), seed index (1000seeds wt.14.44 g), and seed yield (1279.22kg ha^-1). In case of irrigation maximum plant population (24.22 m²), height of plant (165.93 cm), branchesplant^-1 (8.09), podsplant^-1(565.22) seeds pod^-1 (12.04), seed index (1000 seeds wt. 17.11 g), and seed yield (1955.11 kg ha^-1). Whereas the minimum plant population(17.11 m²), height of plant (148.80 cm), branchesplant^-1 (6.22), podsplant^-1(637.04) seeds pod^-1 (8.74), seed index (1000 seeds wt. 15.56 g), and seed yield (1579.67 kg ha^-1) was recorded in one irrigation. On the basis of results found it can be able that the balanced fertilization and irrigation scheduling was higher than alone application of treatment due to synergetic effect of NP with irrigation by mustard in terms of growth and seed yield. It was determined that despite the consequences the variation in the values different growth yield traits of mustard crop, the mustard harvest was markedly higher (2407.6 kg ha^-1) when the crop was given NP @ 120-60 kg ha^-1.
