Tomatoes are one of the most important vegetables in every home, especially in South Asian countries, used as a vegetable, ketchup, and condiment in many kitchen recipes. It is a good source of calcium, potassium, folate, vitamin A, vitamin K, and lycopene, which are beneficial for the human body and protect it against different diseases. Nutrient management is a key factor for the best quality production of tomato fruit. The present study was conducted to compare the efficiency of different calcium salts (calcium sulphate, calcium carbonate, calcium nitrate, and calcium chloride) in improving the growth, yield, and other quality-related parameters of tomatoes. A single field experiment was conducted and laid out according to the Randomized Complete Block Design (RCBD) with a single factor in the field and a Complete Randomized Design (CRD)) for postharvest fruit storage. The results obtained from this experiment suggest that plants treated with 2% calcium chloride solution exhibited the greatest plant height (85.27 cm), number of leaves (221), yield per plant (2.3 kg), ascorbate peroxidase (290.75 m mol s−1 kg−1), superoxide dismutase (7.13 m mol s−1 kg−1), catalase (18.74 m mol s−1 kg−1), total phenolics (2.44 mg g−1), and β carotene (0.48 µg g−1). During postharvest storage, the maximum shelf life (18 days), minimum disease incidence (4.78%), weight loss (6.61%), and ethylene production (119.6 µL C2H4 kg−1h−1) rate were also observed in calcium-treated fruits.

In this article we compared two approaches: one is Griffing approach for numerical components and other is Hyman's approach for graphical representation of the components through the mating design of Complete Diallel Cross design for p=5 parental lines. Griffing (1956) approach was a numerical approach based on the estimates of combining ability effects. Here use his fourth method. Hayman (1954) approach also have four components namely (i) complete, (ii) partial, (iii) over-dominance and (iv) no dominance. Hayman's approach based on the estimation of parts of variation. We use three mutually orthogonal Latin squares design of order 5 for the construction of mating designs. ANOVA and estimates of combining ability derived and analyzed. We demonstrate the numerical accuracy of the proposed design Griffing method I and Hayman's method by using Turnip data of 5x5 crosses of plant height. [ABSTRACT FROM AUTHOR]

Chrysanthemum morifolium L. cultivators in Pakistan have frequently detected that poor root cuttings of chrysanthemum caused poor anchorage of roots that results in shipping losses of these pot plants. Optimum concentration of appropriate auxins is used to promote effective rooting. Completely randomized design (CRD) is adopted and it consisted of five treatments including control and different concentration of both auxins viz. 1-Naphthalene acetic acid (50 mg/L,100 mg/L) and Indole-3-acetic acid (100 mg/L, 200 mg/L) on tip cuttings of chrysanthemum. In this experiment, 15 pots of 9-inch diameter were used which were filled with silt, leaf mould and well rotten farmyard manure (1:1:1). Three cuttings in each pot and a total of 45 cuttings were planted. Cuttings of each treatment were dipped for 3 minutes in respective solution before planting. Uprooting was done after 60 days of plantation the cuttings. NAA with 100 mg/L proved best treatments that produced maximum root length, number of roots, dry and fresh weights of roots, number of sprouted buds, number of leaves, leaves fresh weight and dry leaves weight as compared to other treatments and control. This data suggested that NAA can be successfully used to increase root and shoot parameters in chrysanthemum propagated by means of tip cuttings. [ABSTRACT FROM AUTHOR]
