    Storage behaviour of potato as affected by time of haulm killing and harvesting
    (CCSHAU, 2005) Suhag, Munish; Nehra, B.K.
    The investigation “Storage behaviour of potato as affected by time of haulm killing and harvesting was conducted at vegetable research farm and laboratories of CCS HAU Hisar during 2001-02. The study was conducted under two sets. Ist set of samples was used for studies under ambient storage and IInd set was used for cold storage studies. The investigation consisted of eighteen combination of nine treatment of haulm killing at 90, 100 and 110 days after planting and field curing for 0, 10 and 20 days after haulm killing in each treatment with two varieties (Kufri Badshah and Kufri Sutlej). Total tuber yield increased from 246.9 q/ha to 277.4 q/ha in Kufri Badshah and from 216.3 to 248.3 q/ha in Kufri Sutlej with increase in crop duration from 90 to 110 days after planting. The mean weight loss under ambient condition decreased from 11.3% where crop duration was 90 days and no field curing was done to 7.4% where crop duration was 110 days and field curing was for 20 days in Kufri Badshah. Figures for these two treatment in Kufri Sutlej were 14.6 and 11.9% respectively. The mean weight loss increased from 0.9 to 27.5% as the storage period prolonged from 10 to 105 days. Similarly during cold storage mean weight loss decreased as crop duration and field curing increased. After cold storage also weight loss decreased with increase in crop duration and field curing. But after cold storage the mean weight loss increased from 10.1 to 23.5% within one month. Sprouting percentage was decreased from 54.0 to 47.6% in Kufri Badshah and 55.1 to 50.3% in Kufri Sutlej as the crop duration increased from 90 to 110 days and field curing was allowed for 20 days. Sprouting percentage increased from 22.5 to 76.1% during storage from 60 to 150 days. As the crop duration and field curing increased mean dry matter content also increased. It ranged from 16.5 to 18.1% in Kufri Badshah and 15.3 to 17.9% in Kufri Sutlej with increase in crop duration from 90 to 110 days and field curing was allowed from 0 to 20 days. The dry matter content also increased as the storage period increased. It ranged from 16.4 to 17.3% during storage of 30 to 150 days. Sugar content slightly increased with increase in crop duration and also with field curing, however there was no set pattern. During storage sugar content increased for the first 60 days and lateron it decreased.

    Diallel Analysis in bitter gourd (Momordica charantia L.)
    (CCSHAU, 2005) Gupta, Vishal; Nand Kishore
    The present investigation was undertaken to study correlation, path, combining ability, heterosis and gene effects using 9x9 half diallel set for sixteen characters in Randomized Block Design with three replications at the Vegetable Research Farm and Laboratory, CCS Haryana Agricultural University, Hisar during spring-summer season, 2003. Analysis of variance indicated sufficient variability among parents and their hybrids. Significant positive correlations were observed for fruit length with number of fruits per plant, average fruit weight and total fruit yield per vine. Days to first female flower showed the highest direct contribution followed by number of fruits per plant and average fruit 9 weight towards yield while days to first fruit harvest exhibited its highest indirect contribution via days to first female flower followed by fruit length and fruit diameter via days to first fruit harvest. IC-44410 was the best general combiner for average fruit weight, number of fruits and total fruit yield per plant whereas, BL-237 for chlorophyll ‘b’ and ascorbic acid content. IC-44410 x IC-68316, Pusa Vishesh x BL-237 and IC-44410 x BL-237 were rated as the best crosses on the basis of their sca, heterotic effects and per se performance for yield and for one or other yield attributes. Component analysis revealed that all the characters showed non-additive type of gene effects. Medium heritability (ns) was recorded for node to first female flower, fruit diameter, average fruit weight and TSS. Four dominant genes were present for every recessive gene in parents for days to first fruit harvest and average fruit weight. The comparative evaluation of combining ability, component analysis and mean degree of dominance predicted that characters viz., fruit length, number of fruits per plant, average fruit weight, total fruit yield per plant, chlorophyll ‘a’, chlorophyll ‘b’, total chlorophyll, carotenoid, ascorbic acid and dry matter contents showed non-additive gene effects and hence these characters can be improved through hybridization.

    Storage studies in pea under different types of polythene and storage conditions
    (CCSHAU, 2006) Singal, Vikramjeet; Malik, T.P.
    The present investigation was carried out at the Post Harvest Laboratory of the Department of Vegetable Science at CCS Haryana Agricultural University during the year 2006. The main objective was to enhance the shelf life of pea pods and grains of varieties i.e. Arkil under ambient room temperature and zero energy chamber using different types of packaging materials viz., polyethylene bags (LDPE, HDPE and PVC) and News paper bags of 1 kg capacity for pods. LDPE packing at zero energy chamber storage was most effective in checking the PLW and decay loss. There was continuous decrease in sugar, TSS, chlorophyll content irrespective of the packaging treatments. However carotenoids content showed an increasing trend. Penicillium sp., Colletotrichum sp., Fusarium sp. & Aspergillus sp. were the main causal organism responsible for the decay. Among different treatment LDPE pods and grains packing at zero energy chamber storage were the best in maintaining physical, biochemical and pathological parameters up to 12th and 8th day respectively of storage. Whereas maximum degradation of fruits was found in News paper stored at room temperature.

    Production of hybrid seed using GA3 and genetic markers in tomato (Lycopersicon esculentum Mill.)
    (CCSHAU, 2005) Ram Narayan Singh; Batra, Vinod
    The present study was conducted at CCS HAU, Hisar for production of hybrid seeds using different concentration of GA3 and genetic markers. Five lines, i.e., selection-21 (potato leaf type), CLN-2366A, CLN-2116D9F1-180-31-9-40, CLN-2-16-8-2-176 and EC-339357 (anthocyaninless type) were used as female parent. Three lines Hisar Arun, H-86 and VFN-8 were used as male parent are cut leaf type and anthocyanin present on the hypocotyl. Cut leaf type is dominant over potato leaf type and anthocyanin type is dominant over anthocyaninless type. GA3 was sprayed 40 and 60 days after transplanting as whole plant spray @ 50 and 100 ppm. Fifteen different crosses were made and observations for per cent fruit set, number of seeds per fruit, seed germination, seed vigour index I and II and percent hybrids plants. Confirmation of markers was done at early stage of seedling in the green house. Among all the treatments, the GA3 50 ppm was found best for fruit setting and seed germination. However, for the number of seeds per fruit and seed vigour index I and II, hand emasculation and hand pollination was at par with GA3 50 ppm. The per cent hybrid plants identified at seedling stage were non significant under different treatments. However, cost of producing hybrid seed was 38% less in GA3 50 ppm as compared to hand emasculation and hand pollination. The futuristic approach of hybrid seed production using different concentrations of GA3 on different genetic markers and ancillary investigations have been suggested.

    Effect of crop residues and FYM on yield and quality of carrot roots (Daucus carota L.)
    (CCSHAU, 2005) Ashwini Kumar; Rana, M.K.
    The present study entitled “Effect of crop residues and FYM on yield and quality of carrot roots (Daucus carota L.)” was carried out at Vegetable Research Farm of CCS Haryana Agricultural University, Hisar during winter season of 2004-05. The experiment comprising twelve treatments, viz. T1 (maize root incorporation), T2 (sorghum root incorporation), T3 (pearl millet root incorporation), T4 (dhaincha root incorporation), T5 (maize root incorporation + recommended decomposed FYM), T6 (sorghum root incorporation + recommended decomposed FYM), T7 (pearl millet root incorporation + recommended decomposed FYM), T8 (dhaincha whole plant incorporation), T9 (recommended decomposed FYM), T10 (recommended un-decomposed FYM), T11 (recommended NPK), T12 (control) was laid out in a randomized block design with three replications and 3x3 m plot size. Ten competitive plants were randomly selected from each experimental treatment to record data on various parameters, which were influenced significantly by various treatments. The crop residues had negative effect on all the characters studied during the course of experimentation. Incorporation of recommended decomposed farmyard manure in soil increased the root length, shoot length, average crown diameter, dry matter content, TSS content, and carotene content, however, decreased the forking of carrot roots significantly. Similarly, application of recommended dose of NPK had significant positive effect on all the characters mentioned above in addition to cortex: core ratio, root: shoot ratio and yield. The study suggested that for getting maximum root yield of carrot the crop should be supplied with recommended dose of NPK, and so far quality was concerned farmyard manure and recommended NPK had similar effects, however, incorporation of crop residues produced adverse effect on growth, yield, and quality attributes.

    Effect of Azotobacter and nitrogen on tomato production
    (CCSHAU, 2006) Virender; Malik, Y.S.
    The present investigation was conducted during 2005 at vegetable research farm of CCS HAU Hisar to study the effect of Azotobacter and nitrogen on tomato production. There are four nitrogen levels (0, 50, 75,100 kg/ha) and five Azotobacter strains (0, Ala-27, Mac-21, Mac-27, Mac-68). Experiment was layout in Spilt Plot Design allocating nitrogen levels to main plots. Transplanting was done on 31 Jan 2005. Application of 100 kg N/ha significantly improved plant height, number of fruits per plant and total fruit yield but it delayed flowering in comparison to other nitrogen levels. Maximum fruit yield per plant and 12 per hectare was recorded with 100 kg N/ha. However, it was statistically at par with 75 kg N/ha and significantly superior to other doses of nitrogen. Similar results were observed in case of seed quality (weight of seed per kg fruits, test weight, germination %). Inoculation of Azotobacter strains improved the growth and yield attributes significantly over control. Maximum fruit yield per plant and total fruit yield (q/ha) was recorded with strain Mac-27 which was closely followed by Mac-68 and these were significantly superior to control. Interaction effect of nitrogen and Azotobacter strains was significant on growth, fruit yield and seed weight per kg fruits. Highest fruit yield per plant and total fruit yield (q/ha) was under the combination of 100 kg N/ha and Azotobacter strain Mac-27. However, it was at par with all the treatment combinations of 100 kg N/ha and remaining Azotobacter strains and 75 kg N/ha plus Mac-27 and significantly superior to other treatment combinations.

    Heterosis and combining ability studies in broccoli
    (CCSHAU, 2006) Anthwal, Abhilasha; Partap, P.S.
    Fourty three genotypes comprising 13 parents (10 females and 3 males) their 30 hybrids were grown in randomized block design with three replications to study the combining ability and heterosis in broccoli. The analysis of variance indicated the presence of sufficient genetic variability for all the characters studied. Among female parents, BH-25-3-6, BH-25-3-7, DBG-B-12 and among male parents Broccoli No.1 and Cavolo Broccolo Notalima showed high gca effects for yield and other yield attributing traits. The cross BH—25-3-7  Atlantica and DBG-B-12  Broccoli No. 1 showed high sca effects for yield and related attributes. The crosses Palam Haritika  Cavolo Broccolo Notalima, BH-29-5-6  Atlantica showed high heterosis for yield and other yield contributing traits. For number of days to 50 % BH-25-3-6 was good general combiner amongst the female parents and Cavolo Broccolo Notalima among male parents, as they took minimum number of days to 50 % harvest. Among the crosses BH-14-4-2 x Cavolo Broccolo Notalima was best specific combiner as it showed significant and negative sca effect. In case of hetrosis over better parent and mid parent, the cross Palam Haritika x Cavolo Broccolo Notalima showed significant and negative heterosis for days to 50 % harvest BH- 14 – 4 – 2 x Cavolo Broccolo Notalima exhibited significant heterosis over best parent for number of days to 50 % harvest.

    “Seed quality assessment in naturally aged seed of coriander (Coriandrum sativum L.)
    (CCSHAU, 2007) Anil Kumar; Tehlan, S.K.
    The present study was carried out on ten genotypes of coriander (DH-202, DH-205, DH-206, DH-208, DH-228, DH-234, DH-242, DH-266, Hisar Anand and Pant Haritma with the objectives to study the effect of natural ageing on seed quality parameters in coriander by various tests and parameters viz ; test weight, standard germination test, tetrazolium test, seedling length, seedling dry weight, electrical conductivity of seed leachates, speed of germination, vigour index-I, vigour index-II, dehydrogenase activity test and field emergence index and, to determine the association of various seed quality parameters with field emergence. The viability and vigour of seeds declined to varying degrees in different genotypes of coriander during xv ambient storage. Genotypes DH-208 and DH-266 were found most promising for various parameters of vigour and viability. Genotypes DH-205, DH-206, DH-208, DH-266, Hisar Anand and Pant Haritma retained standard germination above 60 % in the one year old seed lot. During natural ageing, the standard germination, seedling length, dry weight, vigour index-I and vigour-II, viability percentage and test weight decreased significantly and progressively with ageing period. The interaction among genotypes and ageing period was found significant for all the characters under study except standard germination test, vigour index II and tetrazolium test (seed viability). The test weight, standard germination test, vigour index-I, dehydrogenase activity test and tetrazolium test emerged as reliable predictors of field emergence index.
