Interaction Effect of Sowing Time and Nitrogen Levels on Growth and Yield Parameters on Cauliflower (Brassica Oleracea Var. Botrytis)
Abstract
The present investigation entitled Interaction effect of sowing time and nitrogen levels on growth and yield parameters on Cauliflower (Brassica oleracea var. botrytis) was carried out using 10 treatment combinations and was laid out in Factorial Randomized Block Design (FRBD) with three replications. The experiment comprised two main parameters, namely the sowing dates and the nitrogen levels. Sowing Time was 15th September & 20th October while Nitrogen levels were kept 50Kg N/ha, 65Kg N/ha, 100Kg N/ha,125Kg N/h, 150Kg N/ha respectively. Appropriate analysis of variance on the results of each experiment was performed and the data obtained from the field surveys was pooled and then data was analysis with the help of OP STAT software. It could be concluded that the nitrogen level 150kg/ha show maximum result both ingrowth and yield characters and sowing date 20th October performs well in all parameters. The combined effect of sowing dates and nitrogen levels showed that sowing on 20th October, nitrogen level 125kg/ha performed well in respect of contributing growth characters and yield.

Introduction
Cauliflower (Brassica oleracea var. botrytis) is a cruciferous vegetable that belongs to the Brassicaceae family, which also includes other vegetables like broccoli, cabbage, and Brussels sprouts. Cauliflower is native to the Mediterranean region and has been cultivated for thousands of years. It has become a popular vegetable worldwide due to its mild flavor and versatility in cooking. Cauliflower is a low-calorie and nutrient-dense vegetable. It's an excellent source of vitamins and minerals, including vitamin C, vitamin K, vitamin B6, folate, and potassium. It also contains dietary fiber and antioxidants. The edible part of cauliflower is known as curd, which consists of a shoot system with short internodes, branches apices and bracts. The edible portion of this vegetable is approximately 45 percent of the vegetable as purchased. It has high quality of proteins and peculiar instability of vitamin C after cooking. It is rich in minerals such as potassium, sodium, iron, phosphorus, calcium, magnesium etc. It also contains vitamin A (Nath, 1976) Conew (1959) has made an analysis on fresh weight basis. Cauliflower contains 92.7 percent water and the food value per 100 g of edible ascorbic acid 70 mg, thiamine 0.2 mg, riboflavin 0.1 mg and niacin 0.57 mg. Sulphur containing compounds viz; hydrogen sulfide methanethiol, ethanethiol, propanethiol and dimethyl sulfide in addition to acetaldehyde and 2-methyl propanol have been identified in cooked cauliflower. It’s a well-known fact that a crop when sown at optimum time is able to exploit all the environment factors efficiently in the process of dry matter accumulation. The date of sowing is governed mainly by temperature, sunlight intensity, duration and rainfall. These are the crucial factors that can decide establishment, growth and performance of crop through changing morphological system, physiological functioning and time available for the crop to complete its life cycle. Due to different factors seedling vigour is also affected which motivated researchers to evaluate the various sowing dates for growth and yield parameters of cauliflower. Therefore present study was done to investigate Interaction effect of sowing time and nitrogen levels on growth and yield parameters on Cauliflower (Brassica oleracea var. botrytis) under different growing conditions.
Conclusion
It could be concluded that the nitrogen level 150kg/ha show maximum result both ingrowth and yield characters and sowing date 20th October performs well in all parameters. The combined effect of sowing dates and nitrogen levels showed that sowing on 20th October, nitrogen level 125kg/ha performed well in respect of contributing growth characters and yield.
