The present study entitled, “Influence of nitrogen levels and spacing on seed yield and economics of fennel (Foeniculum vulgare Mill.)” was conducted during the Rabi season of 2021-22 with fennel variety HF-143 using four different nitrogen levels (0, 25, 50 and 75 kg ha-1) and three-row to row spacing (30x20 cm, 45x20 cm, and 60x20 cm). Sowing of the crop was done on 30th October 2021 in factorial randomized block design (RBD), and harvesting on 10th May 2022. The yield parameters, i.e., number of umbels per plant, number of umbellate per umbel, seeds per umbels, and seed yield (per plot and hectare), were recorded with three replications of each treatment. The economics of each treatment was also calculated. The result revealed that 50 kg N ha-1 treatment with 45x20 cm spacing was best for obtaining higher seed yield. Fertilizing the fennel crop with 50 kg ha-1 nitrogen level and sowing at 45x20 cm is economical to obtain a high seed yield. Though seed yield increased with an increase in nitrogen fertilizer dose, the rise in the value of seed yield from 50-75 kg N ha-1 was found non-significant. From the present study, it can be concluded that the fennel crop produced a higher seed yield (18.23 q ha-1), maximum net return (Rs. 1,14,670 ha-1), and benefit-cost ratio i.e., B: C (2.71) at 50 kg N with 45x20 cm spacing under the semi-arid, subtropical condition in sandy loam soil of Haryana.
An experiment was undertaken to categorise the coriander genotypes based on visual morphological diagnosis. The investigation was carried out at research farm area of department of vegetable science, Chaudhary Charan Singh Haryana Agricultural University, Hisar during the year 2011-2012. Sixty genotypes of coriander obtained from the Department of Vegetable Sciences were studied for the experiment, the seeds of all the genotypes were sown in Augmented block design (ABD) in four blocks with 15 entries in each block along with 4 checks (DH-5 = Hisar Anand, DH-36 = Hisar Sugandh, DH-228 = Hisar Bhoomit and DH-246 = Hisar Surbhi) randomized with in block with single row of 3.0 m length at spacing of 50 X 20 cm within each row. Plant morphological parameters i.e. stem pubescence, stem colour, streaks on stem and number of primary and secondary branches per plant of all sixty genotypes was recorded for categorization. It was found from the results that out of total sixty genotypes, maximum genotype's stem were pubescence, purple in colour and were more branched in terms of primary and secondary branches. These parameters showed wide divergence and hence these can be used as varietal identification.
Three seed lots of fifteen genotypes of coriander were subjected to study the effect of natural ageing on different seed quality parameters. Results revealed that all the genotypes showed the germination percentage above the Minimum Seed Certification Standards (65%) in Lot-1 (freshly harvested seed) and Lot-2 (1 year old seed). Standard germination (%), seedling length (cm), seedling dry weight (mg), seedling vigor index-I & II and accelerated ageing test (%) revealed that quality of seeds declined with faster rate inLot-3 (2 years old seed). Among all the genotypes, maximum germination was retained by genotype DH-339 (75.5%) followed by Hisar Surbhi (74.5%) and maximum loss of germination was observed in genotype DH 352-1 (61.2%). Hence, the genotypes DH-339 and Hisar Surbhi were found superior in terms of viability, vigor and storability whereas genotype DH 352-1 was found poor under ambient conditions.
