    Effect of planting season on seed yield, yield components and seed quality in maize hybrids (Zea mays L)
    (CCSHAU, 2018) Nidhi; Bhuker, Axay
    Four maize hybrids produced during rabi and kharif seasons were evaluated for their performance for different viability, vigour and yield parameters viz. standard germination, seedling length, seed weight, seed density, seedling dry weight, vigour index-I, vigour index-II, accelerated ageing test, electrical conductivity, tetrazolium test, dehydrogenase activity test, catalase activity test, peroxidase test, lipid peroxidation test, protein content, field emergence index, seedling establishment, number of leaves, number of cobs, cob length, plant height, days to 50 % tasseling, days to 50% silking, number of seeds per cob and seed yield to assess the effect of planting season on seed yield, yield components and seed quality in maize hybrids. The rabi season produced seed showed superiority over kharif season for all the seed quality and yield parameters. Among the hybrids, HQPM-5 had the top rank for almost all the vigour, viability and yield parameters in both the seasons (rabi and kharif) indicating its superiority over other hybrids. Standard germination was found significantly and positively correlated with most of the seed quality parameters except electrical conductivity and lipid peroxidation in both the seasons. Electrical conductivity and lipid peroxidation was found significantly and negatively associated with most of the parameters recorded in laboratory and field. On the basis of correlation study, it can be concluded that the viability test like tetrazolium test, electrical conductivity test, dehydrogenase activity test, accelerated ageing test, catalase activity test and lipid peroxidation test can be used as reliable predictor of standard germination in maize and rabi season can be considered as a better option for the production of quality seed in maize in Haryana

    Studies on the pollination mechanisms in different varieties of plum (Prunus domestica L.)
    (CCSHAU, 2011) Nidhi; Sihag, R.C.
    Insects are associated with flowering plants since their evolution on the earth. While some of them act as their pests, others are either pollinators or parasites and predators of the pests. Although a variety of insects frequent the entomophilous (insect pollinated) crop blossoms for their food rewards (nectar and pollen), only bees belonging to the genus Apis outnumber others and are efficient pollinators. Plums are richest sourse of antioxidants, they provide protection against diseases. The study was made on floral biology and phenology, diversity, relative abundance and pollinating efficiencies of insects visiting the blossoms of three different varieties of plum and the role of different modes of pollination in fruit set of the three varities of plum. Flowering habit of all the three varieties of this study viz. Alu Bokhara, Titron and Kala-Amritsari was similar. Floral structure was studied under dissecting microscope revealed the presence of perigynous condition in the flowers of plum. Abundance of insect visitors studied at hourly and weekly intervals which was maximum during peak flowering period of this plant. Twelve insect species visited the crop of plum; out of these five species i.e. Apis dorsata, A.mellifera, A.florea, A.cerana and Dipterans were the main pollinators.Among the hymenopterous insects, Apis.mellifera visited maximum number of flower per minute, followed by A.cerana, A.dorsata, A.florea and Dipterans Among all the insect visitors, Apis dorsata remained active for the longest duration on plum flower followed by, A.mellifera, A.cerana A.florea and Dipterans respectively. Out of the three varieties Titron was the most prefered variety by the insect visitors followed by Kala-Amritsari and Alu-Bokhara.Pollinating efficiencies of the pollinators were derived on the basis of their abundance, foraging rate, mean activity duration and loose pollen grains on the body of insect. Among the five insect pollinators Apis dorsata came out to be on the first place and seemed to be the best pollinator of this crop .Other pollinators with relatively lower ranking in descending order of pollinating efficiency were A.mellifera, A.cerana A.florea.Studies on fruit set parameters revealed that plum flowers were highly benefited from insect visits, and insect pollination greatly enhanced its fruit set. Crop without insects produced very low fruit set. It was further revealed that plum is a cross-pollinated and entomophilous plant.The structure shape and fertility status of the flower clearly revealed that it has honeybee pollinated flowers and mellitophily pollination syndrome existed in plum.

    Development and evaluation of RTS (ready-to-serve) beverage and squash from bael-guava blends
    (CCSHAU, 2006) Nidhi; Gehlot, Rakesh
    The present investigation entitled "Development and evaluation of RTS (ready-to-serve) beverage and squash from bael-guava blends" was carried out with the objectives to standardize appropriate combination of bael-guava blends for preparation of RTS (ready-to-serve) beverage and squash and also to evaluate nutritional constituents and organoleptic quality of blended beverages during storage. Fresh bael and guava fruits were analyzed for different physico-chemical parameters. Data showed that bael and guava fruit had fruit weight (618 and 72g), pulp weight (663 and 927g/kg fruits) and peel weight (302g/kg fruit) and, whereas, pulp : peel ratio (2.19) and seed percentage (3.38 and 2.76%), respectively. Chemical constituents of bael and guava fruits such as moisture content, TSS, total sugars and reducing sugars percentage were found to be (61.76 and 83.34%), (34.50 and 13.50%), (16.93 and 8.56%) and (4.57 and 3.23%), whereas, acidity, pH, ascorbic acid, crude fibre, pectin and total phenols were analyzed to be (0.41 and 0.47%), (4.62 and 4.46), (17.25 and 167.50mg/100g), (3.27 and 2.85%), (2.38 and 0.95%) and (23.71 and 2.26mg/100g), respectively. Nutritional constituents of prepared beverages (ready-to-serve beverage and squash) were studied after processing and during storage period (two months) at monthly interval. It was concluded from the present investigation that overall acceptability of all beverages increased by blending guava pulp with bael pulp in comparison to bael or guava pulp used alone for preparation of beverages. RTS beverage prepared with 15 percent pulp (25 Bael : 75 Guava), 15 percent TSS and 0.26 percent acidity was highly acceptable (8.49) followed by RTS beverage prepared with 20 percent pulp (25 Bael : 75 Guava), 15 percent TSS and 0.26 percent acidity (8.37). Squash prepared with 30 percent pulp (25 Bael : 75 Guava), 50 percent TSS and 1.00 percent acidity was found most acceptable (8.21) followed by squash prepared with 35 percent pulp (25 Bael : 75 Guava), 50 percent TSS and 1.00 percent acidity (8.16). The comparative study of all the beverages revealed that the beverage blends prepared with 25 Bael : 75 Guava pulp ratio were highly acceptable followed by 50 Bael : 50 Guava pulp and 75 Bael : 25 Guava pulp ratio. Acceptability of all the beverages prepared from bael-guava blends slightly decreased with increase in storage period. Total sugars, reducing sugars, acidity and browning increased, whereas, pH, ascorbic acid and total phenols decreased in all the beverages during storage period. Ascorbic acid content of blended beverages showed an increasing trend with increase in proportion of guava pulp in the blends. In RTS beverage, cost of production was maximum (Rs.1.66/200ml) in beverage type (0 bael : 100 guava) with 20 percent pulp, 15 percent TSS and 0.26 percent acidity and minimum (Rs. 1.29/200ml) in beverage type (100 bael : 0 guava) with 15 percent pulp, 15 percent TSS and 0.26 percent acidity. In squash, cost of production was maximum (Rs. 18.57/700ml) in beverage type (0 bael : 100 guava) with 35 percent pulp, 50 percent TSS and 1.00 percent acidity and minimum (Rs.16.63/700ml) in beverage type (100 bael : 0 guava) with 30 percent pulp, 50 percent TSS and 1.0 percent acidity.
