Abstract

Healthy and uniform bulbs of tulip cv. 'Apeldoorn' were planted in two consecutive growing seasons under polyhouse conditions in FRBD design to study the effect of nutrient management on growth, flowering and bulb production in tulip in the Kashmir valley. Experimental treatments comprised of three levels of nitrogen (0,75 and 150 kg ha^-1) and two levels of phosphorus (0 and 50 kg ha^-1), potassium (0 and 50 kg/ha) and zinc (0 and 5 kg ha^-1). Except for bulb survival, nitrogen @ 75 kg ha^-1 significantly improved all the parameters. However, further increase in dose of nitrogen (150 kg ha^-1) influenced only a few parameters like scape length, wrapper leaf area, vase life and bulblet weight per plant. Application of phosphorus, potassium and zinc also resulted in better growth, flower quality and bulb production. Application of different nutrients caused increased concentration of nutrients in leaf tissue, which resulted in better performance of the plant. Combined application of N, P, K and Zn @ 75, 50, 50 and 5 kg ha^-1, respectively, was found to be the most suitable dose for obtaining better growth, quality flower and bulb production.

Abstract

Ten pomegranate (Punica granatum L.) cultivars, namely, Kabuli Kandhari, Chawla, Ganesh, Mridula, Jyoti, G-137, Dholka, Bedana, Kandhari and Local Check were evaluated for different physical and chemical characteristics of fruit at the Central Institute of Temperate Horticulture, Srinagar, during 2004. Fruit weight, diameter and volume was significantly higher in cv. Bedana compared to the rest of the cultivars. Cultivar Kandhari recorded significantly less rind thickness when compared to other cultivars. Cultivar Chawla exhibited less cracking per cent followed by Kandhari. Total soluble solids and total sugars were highest in cv. Kandhari whereas less acidity was recorded in cvs. Ganesh and G-137% acidity was lowest in cv. G-137 (0.41) and highest in cv. Bedana (0.81). Highest ascorbic acid content was found in cv. Kabuli Kandhari. The highest anthocyanin content was observed in cv. Ganesh and lowest in cv. Chawla. Juice content was found to be maximum in Bedana. The lowest anar butterfly attack was observed in cv. Bedana. The data revealed overall superior performance of cv. Bedana and Kandhari with regard to physical and chemical characteristics and these can be recommended for commercial cultivation in the Karewa belt of Kashmir valley.

Abstract

Experiments were conducted during 2002-03 and 2003-04 to study the influence of storage methods and duration on post harvest quality of cut tulip cv. Cassini. Cut tulips cv. Cassini stored either dry or wet at 4°C for 0,2,4,6 and 8 days showed that days to flower opening was the lowest in those kept under wet storage for 6 and 8 days. Flower opening was better with 0.2 and 4 days of dry or wet storage whereas flowers stored dry for 8 days did not open at all. Flower size and vase life decreased with the increase in storage period. Larger flowers were obtained with dry and wet storage of 0 and 2 days whereas higher vase life was obtained with zero days of wet and dry storage and 4 and 6 days of wet storage.
