Effect of Spacing and Nutrition on Soil Nutrient Status and Uptake of Broccoli (Brassica oleracea var. italica)

A field study was conducted to investigate the influence of spacing and nutrition on soil nutrient status and Uptake of Broccoli and the investigation was titled "Effect of spacing and nutrition on soil nutrient status and uptake of Broccoli." The experiment consists of 3 limits of spacing i.e., S1 (45x30 cm), S2 (45x45 cm), S3 (60x45 cm) and 3 limits of nutrient i.e., N1 (100 percent recommended dose of nutrients), N2 (75 percent recommended dose of nutrients), N3 (125 percent recommended dose of nutrients). It was designed in FRCBD includes nine treatment combinations with three replications. The analysed experimental data showed that the available nutrient in the soil and nutrient uptake by the plant after harvesting of Broccoli. Increasing the spacing and nutrient levels enhances the soil N, P and K availability and absorbed by the broccoli after harvesting. The maximum availability of N (296.57kg ha-1), P (116.54kg ha-1) and K (72.85kg ha-1) in the soil was found in the S3. The higher availability of N (275.20kg ha-1), P (104.88kg ha-1) and K (71.37kg ha-1) in the soil was shown in the fertilizer limit N3. The higher N (160.16kg ha-1), P (127.13kg ha-1) and K uptake (65.83kg ha-1) by the Broccoli was reported in the wider level of spacing S3. The maximum N (158.09kg ha-1), P (127.94kg ha-1) and K uptake (65.84kg ha-1) by Broccoli was observed in the nutrient level of N3.
