    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.

    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.
