Abstract

To investigate the effect of organic and inorganic fertilization on the morpho-phenological traits of sugar beet genotypes (Beta vulgaris L.) an experiment was conducted at New Developmental Farm, The University of Agriculture, Peshawar, during winter 2011-12. The design used was randomized complete block design with split plot arrangement. Three replications were used in this experiment. Treatments consists of organic and inorganic fertilizers treatments e.g., (control, Farm yard manure @ 10 t ha-1, maxicrop sea gold (extract of sea weeds @ 5 lit ha-1 was sprayed at the foliage), Higo organic plus (composted manure @ 5 t ha-1), and three nitrogen and phosphorus levels, NP (90:60), NP (120:90), NP (150:120) kg ha-1. Three sugar beet genotypes Sandrina, Serenada and Kawe Terma were also studied in this experiment. The result showed that highest number of leaves plant-1 (27.7), leaf area (170.8 cm2), leaf area index (3.9) and beet length (35.8 cm) were recorded with the application of NP levels at the rate of 150:120 kg ha-1. Highest beet weight plant-1 (1 kg), beet diameter (11.4 cm) and unit area biomass (109.2 t ha-1) with the application of Nitrogen and Phosphorus at the rate of 120:90 kg ha-1. Sugar beet genotype Sandrina show highest leaves plant-1 (21), beet length (32.7 cm) and unit area biomass (75.6 t ha-1) followed by Serenada. Kawe Terma show maximum leaf area (138.3 cm2). It is clear from the results that the sugar beet genotype sandrina and Serenada show higher yield components as compared to sugar beet genotypes Kawe Terma. In case of fertilizers treatments the results of Nitrogen and Phosphorus level at the rate of 120:90 kg ha-1 was better. Application of Nitrogen and Phosphorus levels at the rate of 120:90 kg ha-1 and sugar beet genotype Serenada and Sandrina is better as compared to other sugar beet genotype Kawe Terma.
