    Effect of nitrogen levels under different spacing on coriander (Coriandrum sativum L.)
    (CCSHAU, Hisar, 2020) Chaman; Malik, T.P.
    The present study entitled, “Effect of nitrogen levels under different spacing on coriander (Coriandrum sativum L.)” was conducted during the Rabi 2019-20 at research farm, Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar. The nitrogen doses and different row to row spacing plays important role in growth, yield and quality of coriander crop. In the present investigation four nitrogen levels (0, 25, 50 and 75 kg ha-1) and three different row to row spacing (20 x 15 cm, 30 x 15 cm and 40 x 15 cm) were taken into consideration. The nitrogen was applied in two split doses i.e. 50 per cent at sowing and remaining dose at 40 days after sowing (DAS). Vegetative growth parameters i.e. days to emergence, plant height, primary branches and secondary branches (45, 60, 90 DAS and at harvest), yield and yield attributes were recorded. The quality parameters i.e. test weight, electrical conductivity, standard germination and vigour indices were also recorded in in-vitro condition after harvesting. It was observed that nitrogen dose at 75 kg ha- 1 and row to row spacing 40 x 15 cm was well suited for vegetative growth except plant height that was best in 20 x 15 cm spacing. The seed yield (2119 kg ha-1) and other yield attributes were found highest at 75 kg N ha-1 with spacing 40 x 15 cm and lowest in control. The quality parameters were recorded highest with 75 kg N ha-1 and spacing 40 x 15 cm and the highest cost of cultivation (Rs. 48445 ha-1) was occurred in coriander sown at higher nitrogen levels under different spacing. Among different treatments, highest gross returns of Rs. 158925 ha-1 and highest net returns of Rs. 110480 ha-1 were obtained at 75 kg N ha-1 with 40 x 15 cm. While comparing the, benefit cost ratios, highest B: C (2.29) was recorded at 50 kg N ha-1 with 30 x 15 cm.

    Standardisation of steckling size and plant spacing on seed production of carrot (Daucus carota. L)
    (CCSHAU,HiSAR, 2020-06) Yadav, Monika; Makhan Lal
    Carrot (Daucus carota L.) with chromosome number (2n) = 18 and belonging to the family Umbelliferae is one of the important root vegetable crops. Its cultivated forms have been domesticated from wild species. At first, it grows a rosette of leaves while, building the enlarged taproot. The fast growing cultivars mature within three months of sowing, while the slow growing cultivars mature four months after sowing. The roots contain high quantity of alpha- and beta-carotene, and are a good source of vitamin K and vitamin B6, thus, it is second most important crop in England after potato. Carrot roots are used as salad, cooked vegetable and in the preparation of soups, stews, pickle and sweetmeat. In India, root to seed is the standard method for the production of high quality seed as this method allows for the selection of healthy and true to type roots for the planting of stecklings. If the seed quality is not good, it may again be difficult to get enough number of uniform roots. One of the major problems faced by carrot growers in India is the unavailability of required amount of good quality seed. The yield of carrot seed can be increased by using healthy planting material and proper planting distance. A lot of work has been conducted on production technology but a little work has been carried out on carrot seed production. The relationship between harvest index and plant density in carrot seed production is very useful in optimizing plant population for maximum seed yield and quality. This study was conducted at Seed Research Area of Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar during spring-summer season of 2018-19.The objectives of the investigation were to study the effect of steckling size and plant spacing on growth, seed yield and quality parameters of carrot seed. The experiment comprised five treatments of plant spacing (60 x 30 cm (Flat), 60 x 45 cm (Flat), 60 x 60 cm (Flat), 60 x 30 cm (Single row on ridge), 60 x 45 cm (Paired row on ridge)and three steckling size (8 cm, 6 cm and 4 cm) was laid out in Randomized Block Design with three replications. Highest seed yield of carrot cv Hisar Gairic was obtained with plant spacing of 60 x 45 (Paired row on ridge) which was statistically at par with plant spacing of 60 x 30 cm (Single row on ridge) with stecklings of 8 cm. However, the quality parameters of seed were found better at plant spacing of 60 x 60 cm (Flat) with steckling size of 8 cm.

    Integratenutrient management studies in chilli (Capsicum annuum L.)
    (CCSHAU,HiSAR, 2020-07) Yugvinder; Kuldeep Kumar
    The present investigation was carried out at the Research Farm of the Department of Vegetable Science and in the laboratories of the Department of Soil Science and Vegetable Science, CCS Haryana Agricultural University, Hisar, Haryana during the summer season of 2019-20 to evaluate the effect of integrated nutrient management on the growth, yield and quality of chilli and the Seed of chilli cv. “Kashi Anmol” was grown with thirteen different treatment combinations. All the treatments were assessed for the growth, yield and quality parameters. The experimental results revealed that the application of Recommended NPK + Vermicompost @ 2 t/ha + Azotobacter (T3) followed by treatment T5 (50 % NPK + FYM @ 12.5 t/ha + Vermicompost @ 2 t/ha + Azotobacter) and T4 (Recommended NPK + FYM @ 12.5 t/ ha + Azotobacter) performed superiorly over the other treatments with remarkably higher values for all the growth yield and quality attributes viz., plant height (cm), number of primary branches, days to first fruit harvest, average fruit weight (cm), yield per plot and per hectare, ascorbic acid (mg/100g), total soluble solids (%) and NPK uptake by the plant (g/plant). During the investigation the net returns and benefit cost ratio was also found highest in these treatments. However, minimum values for these attributes were recorded under control (T13). Therefore, to reduce the cost of chemical fertilizers with maintaining sustainability of soil fertility and for higher yield and benefit-cost ratio the chilli crop may be supplied with 50 % Recommended NPK + FYM @ 12.5 t/ha + Vermicompost @ 2 t/ha + Azotobacter as per treatment (T5).
