Pomegranate (Punica granatum L.) is a tropical fruit and grown in many parts of the world predominantly in the Mediterranean region. Fresh seeds (arils) are consumed. Arils contain around 80 per cent of juice and 20 per cent of seed. However, quick browning and desiccation are the important concerns of quality during postharvest storage. To prevent quick moisture loss and browning of arils, applied different concentrations of black cumin seed oil and starch as a coating to improve the shelf life and quality of arils. Results showed that pomegranate arils coated with Nigella sativa oil at 200 ppm concentration recorded significantly lowest total sugars content and titrable acidity during the initial stages, whereas at later stages recorded significantly highest total sugars (14.408 and 13.687, respectively on days 12 and 16) and titrable acidity (0.382 and 0.358 on day 12 and 16). Further, arils treated with Nigella sativa oil at 200 ppm concentration recorded significantly lowest per cent of spoilage, physiological loss in weight and recorded significantly highest antioxidant activity, ascorbic acid and anthocyanins content. At the end, it was noticed that edible coating did not affect the natural flavour of pomegranate arils.Keywords

An investigation was carried out at Horticultural College and Research Institute, Venkataramannagudem, West Godavari district of Andhra Pradesh during the year 2015-16 to evaluate the influence of graded levels of nitrogen and potassium on physiological growth parameters and flower yield of garland chrysanthemum. The study has revealed that significantly highest number of leaves per plant (98.00), leaf area per plant (988.00 cm2), LAI (0.618), LAD (268.04), CGR, AGR, RGR, NAR, Chlorophyll-a, b and total chlorophyll content were observed by application of nitrogen at the rate of 200 kg ha-1 in combination with potassium at the rate of 150 kg ha-1along with phosphorus as a common dose to all the treatments at the rate of 100 kg ha-1during Rabi season. Significantly highest number of flowers per plant (28.00), flower yield per plant (36.00 g) and flower yield per hectare (25.25q) were observed by application of nitrogen at the rate of 200 kg ha-1 in combination with potassium at the rate of 150 kg ha-1.Keywords

A field experiment with two methods and three levels of irrigation using crop factor was carried out on eighteen years old oil palm plantation at ICAR-Indian Institute of Oil Palm Research, Pedavegi to find out their influence on vegetative growth and yield of fresh fruit bunches during the year 2016-2017. The data obtained have indicated non-significant differences for most of the parameters evaluated. However, application of irrigation water through drip method at crop factor 0.8 recorded highest number of leaves produced (25.83), highest number of female inflorescences (7.16), lowest number of male inflorescences (5.12) which contributed to increased production of number of fresh fruit bunches (7.16), total weight of FFBs (148.44 kg/palm/year) thereby FFB yield (21.23 t/ha). Further, the same treatment combination has increased percentage of fruits to the bunch (64.79%).Keywords
