Abstract
The field experiment was conducted during rabi season of 2018-19 and 2019-20 at Research Farm of the Department, Vegetable Science, CCS Haryana Agricultural University, Hisar to study the effect of sowing time, leaf cuttings and nitrogen levels on growth and yield of beet leaf. The experiment was laid out in a Split-Split Plot Design with 27 treatment applications comprised of three sowing dates (22th October, 05th November and 20th November) as main plots, three levels of nitrogen fertilizer (60, 80 and 100 kg N/ha) as sub plots and three levels of leaf cutting (no leaf cutting, one leaf cutting and two leaf cuttings) as sub-sub plots replicated thrice. Morphological parameters like plant height, leaf number, leaf dimensions were recorded significantly higher in 22th October crop with application of 80 kg N/ha and one leaf cutting, as compared to other levels. Phenological parameters like days to 50 % bolting and seed maturity was recorded significantly higher in 22th October crop with application of 100 kg N/ha and two leaf cuttings, as compared to other levels. Yield contributing parameters viz., number of spikes per plant, number of seeds per spike, seed yield per hectare and biological yield along with quality parameters viz., test weight, germination, seedling length, seedling dry weight and vigour indices were recorded highest in 22th October crop with 80 kg N/ha and one leaf cutting, as compared to other levels. Further, the interaction of sowing time, nitrogen level and leaf cutting significantly affected almost all the growth, yield and seed quality parameters. The highest BC ratio (1.71 and 1.75) with net returns (INR 118668/ha and INR 126462/ha) was observed in beet leaf crop sown on 22th October with application of 80 kg N/ha & one leaf cutting. In the end, it is concluded that for achieving the higher yield, better seed quality and net profit, the beet leaf crop may be sown on 22th October with application of 80 kg N/ha and one leaf cutting.
