Abstract

Nitrogen is a primary macronutrient which having a key role in protein synthesis and an essential constituent of amino acids. It is immensely required for better production of radish crop. An experimental research with different nitrogen levels on growth and yield of radish under the climatic condition of Bajaur was performed at Research Farm of Agriculture Research (MAs), district Bajaur. The experimental study was carried out in RCBD with total eight treatments replicated three times and size of each plot was 2 x 2 m2. Eight different nitrogen doses (0, 30, 60, 90, 120, 150, 180 and 210 kg ha-1 N) were given in two split doses, first dose was given during sowing and another dose was applied after 30 days of sowing. The statistical results showed that application of nitrogen positively affected all the studied attributes. Maximum number of leaves per plant (19.68), plant height (37.68 cm), root diameter (7.69 cm), root length (31.62 cm), root weight (412.11 g) and total yield (102.63 t ha-1) were recorded in the plants applied with nitrogen @ 210 kg ha-1. Less number of leaves plant-1 (10.55), plant height (21.07 cm), root length (21.23 cm), root diameter (4.59 cm), root weight (328.47 g) and total yield (83.54 t ha-1) were recorded in the control treatment. It is concluded from the present experiment that utilization of nitrogen @ of 210 kg ha-1 could be applied for higher yield of radish crop under the agro-climatic condition of district Bajaur.

Research Objective

To determine the effect of different nitrogen levels on the growth, quality, and yield of radish under the agro-climatic conditions of district Bajaur.

Methodology

An experiment was conducted at the Agriculture Research Farm, district Bajaur, KP, Pakistan, using a Randomized Complete Block Design (RCBD) with eight treatments (0, 30, 60, 90, 120, 150, 180, and 210 kg ha-1 N) replicated three times. Nitrogen was applied in two split doses, at sowing and 30 days after sowing. Data were collected on number of leaves per plant, plant height, root length, root diameter, root weight, and total yield. Data were analyzed using analysis software statistic 8.1.

Discussion

The increase in growth and yield attributes with higher nitrogen levels is attributed to the role of nitrogen in photosynthesis, cell division, cell enlargement, protein synthesis, and chlorophyll production. These findings are consistent with previous research on the effect of nitrogen on radish and other crops.

Key Findings

Application of nitrogen significantly affected all studied attributes. The highest values for number of leaves per plant (19.68), plant height (37.68 cm), root diameter (7.69 cm), root length (31.62 cm), root weight (412.11 g), and total yield (102.63 t ha-1) were recorded with 210 kg ha-1 N. The lowest values were recorded in the control treatment.

Conclusion

Application of nitrogen at 210 kg ha-1 is recommended for achieving higher yield of radish crop under the agro-climatic condition of district Bajaur.
