    Effect of nitrogen levels and row spacing on growth, seed yield and quality of coriander (CoriandrumsativumL.)
    (CCSHAU, Hisar, 2022-07-22) Ram Mehar; Tehlan, S.K.
    The present study entitled “Effect of nitrogen levels and row spacing on growth, seed yield and quality of coriander (Coriandrumsativum L.)”as conducted during the Rabi 2021-22 at research farm, Department of Vegetable Science, ChaudharyCharan Singh Haryana Agricultural University, Hisar using four different nitrogen levels (45, 60, 75 and 90 kg ha-1) and three-row to row spacing (30 x 20 cm, 40 x 20 cm and 50 x 20 cm). Vegetative growth parameters i.e., plant height, primary branches at harvest along with yield and yield attributes were recorded. The quality parameters i.e., test weight, accelerated ageing test, standard germination, seedling length, seedling dry weight and vigour indices were also recorded. It was observed that nitrogen dose of 90 kg ha1 and row to row spacing 50 x 20 cm was well suited for vegetative growth except for plant height that was best in 30 x 20 cm spacing. The yield attributes were also found highest at 90 kg N ha-1 and 50 x 20 cm spacing which were statistically at par with 75 kg N ha-1and 40 x 20 cm spacing. The seed yield (seed yield per plot and seed yield per hectare) was recorded maximum at 90 kg N ha-1 and 40 x 20 cm spacing which was statistically at par with 75 kg N ha-1and 40 x 20 cm spacing. The quality parameters were recorded highest with 90 kg N ha-1and spacing 50 x 20 cm which were statistically at par with 75 kg N ha-1 and 40 x 20 cm spacing.

    Performance of varieties as affected by different crop geometry with cut seed tuber planting of potato
    (CCS HAU, Hisar, 2022-07) Dagar, Sandeep; Panghal, V.P.S.
    The experiment entitled “Performance of varieties as affected by different crop geometry with cut seed tuber planting of potato” was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar. The treatments comprising of three potato varieties (Kufri Neelkanth, Kufri Bahar and Kufri Lima) and four different spacing (60×10 cm, 60×15 cm, 60×20 cm with cut tuber and 60×20 cm with whole tuber) were laid out in a randomized block design (factorial) with three replications keeping gross plot size 4.8x3.6 m2 net plot size 3.6x3.0 m2. The results revealed that maximum plant emergence recorded at 30 DAP, number and weight of leaves and stems per hill and number of large size tuber (>75 g grade) was recorded at spacing 60x20 cm using whole tuber, which was significantly higher as compared to other spacing. Plant height, fresh weight of foliage per m2, number of >25-50 g size tuber, marketable and biological yield was recorded maximum with 60x20 cm spacing using whole tuber for planting which was at par with 60x10 cm spacing using cut tuber, However, total number of tubers and small size tubers less than 25 g was recorded significantly higher in 60x10 cm plant spacing using cut tuber for planting. Maximum yield of large size tuber (>50-75 and >75 g grade) as well as total tuber yield (395.78 q/ha) was recorded in 60x 20cm spacing using whole tuber for planting, which was at par with cut tuber planting at 60x10 and 60x15 cm spacing. Among the varieties, Kufri Neelkanth and Kufri Lima performed better for plant emergence, plant height, number and weight of leaves and stems per hill, number and yield of tubers of >50-75 g grade as well as total tuber yield as compared to Kufri Bahar. However, maximum marketable tuber yield was recorded in Kufri Lima variety as compared to other varieties. Quality parameters such as dry matter of foliage and tuber, ascorbic acid, reducing sugar and total sugar content was recorded maximum in 60x20 cm spacing with whole tuber for planting. Among the varieties, Kufri Lima and Kufri Bahar recorded higher dry matter, reducing and total sugar content. Whereas, Kufri Bahar recorded minimum physiological, decay and sprouting losses on weight basis as compared to other varieties, hence more self-life in storage. Highest net return (Rs. 2,79,488/-) benefit cost ratio (3.18) was recorded with potato variety Kufri Neelkanth planting at 60×20 cm spacing using whole tuber for planting.

    Grafting studies in cucurbitaceous crops
    (CCSHAU, Hisar, 2022-12) Vikram; Arora, Indu
    The present study entitled “Grafting studies in cucurbitaceous crops ” was carried out at Research Farm of the Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar during summer season of 2019. Grafting crops onto resistant rootstocks is an effective technique in the management of biotic and abiotic stresses. In this experiment, the effect of different rootstocks on plant growth, fruit yield and Fusarium wilt resistance were studied in watermelon and muskmelon. Watermelon (Watermelon Scion 1 and Watermelon Scion 2) varieties were grafted onto 6 rootstock i.e Tarkakdi, Bottleguard- Local, Bottleguard-Wild, Pumpkin, Watermelon and Muskmelon. Non-grafted and self-grafted plants were used as control. Grafting significantly affected plant growth and yield. Fruit yield was positively influenced by grafting when compared with control. Maximum fruit yield per plant (9.64 kg) was found in Watermelon Scion 1 grafted onto Tarkakdi rootstock and minimum Fusarium disease incidence, was found in Watermelon Scion- 2 grafted onto Tarkakdi rootstock. Therefore Tarkakdi rootstock was found best for watermelon grafting. Muskmelon (Muskmelon Scion 1 and Muskmelon Scion 2) varieties were also grafted on 5 rootstocks i.e, Tarkakdi, Bottle guard-Local, Bottle guard-Wild, Pumpkin and Muskmelon. Non-grafted and self-grafted plants were used as control. Grafting significantly affected plant growth and yield. Fruit yield was positively influenced by grafting when compared with control. Maximum fruit yield per plant (6.94 kg) was found in Muskmelon Scion -1 grafted onto Muskmelon rootstock and in fusarium disease incidence, minimum disease incidence was found in Tarkakdi (20.39%) rootstock. Hence, Grafting improved plant growth and yield without any harmful effects on fruit quality.
