| Description |
The present investigation entitled “Effect of dates of planting and nitrogen on growth and yield of cabbage (Brassica oleracea var. capitata. L.)” was carried out in late kharif 2013-2014 at Horticultural College and Research Institute, Venkataramannagudem, Dr.Y.S.R.Horticultural University, West Godavari (Dist.), Andhra Pradesh Present study included 16 treatments each replicated thrice in Factorial Randomized Block Design. The treatments included four levels of planting dates (15thAugust, 1stSeptember, 15thSeptember, 1stOctober) and four levels of nitrogen (100 kg ha-1, 200 kg ha-1,300 kg ha-1,400 kg ha-1). Different dates of planting showed significant influence on vegetative parameters. The growth parameters like plant height, number of leaves per plant and leaf area at all growth stages were maximum with the crop planted on 15th September (D3).The number of days taken to initiation of head, days to harvest and percentage of abnormal heads were found to be minimum with 15th September planting (D3). Similarly crop planted on 15th September (D3) recorded the highest head circumference, volume of head, head weight and estimated yield per hectare when compared to all other treatments. Nitrogen uptake by the plant and available soil potassium were found to be highest with the crop planted on 15th September (D3) and available soil nitrogen was found to be highest with 1st October planting (D4). However, dates of planting had no significant influence on available soil phosphorus. Different nitrogen levels had shown significant influence on vegetative parameters. All the growth parameters like plant height, number of leaves per plant, leaf area and plant spread at different growth stages viz., 30DAT, 60 DAT and at harvest recorded highest values with application of nitrogen @ 300 kg ha-1 (N3).The number of days taken to initiation of head, days to harvest and percentage of abnormal heads were found to be minimum with application of nitrogen @ 300 kg ha-1 (N3). Similarly the crop applied with 300 kg N ha-1 (N3) recorded the highest head circumference, volume of head, head weight and estimated yield per hectare. Nitrogen uptake by the plant and available soil nitrogen content were found better with nitrogen application @ 300 kg ha-1. However, available soil potassium content was highest with application of nitrogen @400kg ha-1(N4).The effect of different nitrogen levels on available soil phosphorus was found non-significant. The interaction effect of dates of planting and nitrogen was found non- significant on vegetative characters. But it had significant influence on yield and yield attributing characters. Among all the treatments, combination of 15th September planting with an application of nitrogen @ 300 kg ha-1 (D3N3) recorded the highest volume of head, head weight and estimated yield per hectare. Similarly the crop planted on 15th September with an application of nitrogen @ 300 kg N ha-1 (D3N3) recorded highest available soil potassium content. Highest benefit cost ratio was also recorded with the same combination. Hence the combination of 15th September planting with an application of nitrogen @ 300 kg ha-1 (D3N3) may be recommended to get higher yields and quality heads of cabbage in coastal Andhra Pradesh. |
