Plants have always been a vital source of medicines and other essential products that have been a part of human life ever since time immemorial. Pharmacognosy and its associated aspects have been going through constant evolution and investigation with every generation revealing different and new pharmaceutical properties of plants and their products. The horticulture sector of India has witnessed a great demand of exotic fruits and vegetables in the last decade. These are either imported or artificially introduced in an exotic and non-indigenous habitat. A large number of these exotic plants which are consumed as fruits and vegetables possess a variety of bioactive phytochemical compounds. These bioactive compounds impart them some really important medicinal and pharmacological properties such as anti-inflammatory, immunomodulatory, hepatoprotective, anticarcinogenic, antiulcerogenic, analgesics etc. This review article is an attempt to briefly address such exotic fruits and vegetables, the bioactive compounds associated with them and their medicinal properties useful to mankind.
The present investigations entitled "Impact of nitrogen and phosphorus on growth and seed yield of Spinach (Spinacia oleracea L.)" was carried out in experimental area of research farm of Guru Kashi Univesity, Talwandi Sabo (Bathinda) during Rabi season 2018-2019.The experiment was laid out in Randomized Block Design (RBD) keeping doses in combination with different rates of nitrogen (0, 35, 70 and 95 kg ha -1 ) and phosphorus (0, 15, 30 and 45 kg ha -1 ) on growth and seed yield of spinach.Results showed that the maximum height of plant was 84 cm, number of branches 10.94 and weight of 100 seeds was 1.30 gram was recorded with the combined application of 95 kg N ha -1 and 45 kg P 2 O 5 ha -1 .Maximum seed yield per plant 6.36 gram and seed yield 285.52 kg/ha were obtained from 95 kg N ha -1 and 0 kg P 2 O 5 ha -1 .
Fresh harvested onion seeds dried to 6.54 per cent seed moisture content were stored in four various packaging materials under two different storage conditions at laboratory of Seed Science and Technology Department, Faculty of Agriculture, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal, to identify the storage environment and packaging materials for better storage of seed.The seeds stored under cold storage condition recorded higher germination, rate of germination, seedling dry weight, vigour index, field emergence and moisture content (80.71%, 24.93, 18.61mg, 1148.80,71.29%, 8.07%, respectively) compared to the seeds stored under room temperature condition and On the other hand Seeds packed in glass container recorded better results regarding said attributes (86.75%, 25.99, 18.56mg, 1246.67,74.50% and 5.73%, respectively) as compare to other packaging materials at the end of six months of storage.The interaction effects of packaging materials and storage conditions also shows marked impact on onion seed storage.It can be concluded that, onion seeds packed in glass container, polythene bag or aluminium foil and stored under cold storage condition maintained better seed quality over a period of six months of storage.
The studies were based on effect of different recipes on storage period of Karonda candy. The experiment comprised of two types of karonda i.e. green and pink with seed and without seed were stored at ambient temperature. From the findings it was observed that, there was a gradual increase in TSS, acidity, reducing sugars and total sugars content of candy irrespective of fruit colour type and recipes used in experimentation. However, pH, nonreducing sugars, ascorbic acid, moisture, iron content of candy were found to be decreased with the advancement of storage period. The karonda candy prepared from different recipes of sugar concentration of 60 B, 65 B and 70 B can be stored upto 120 days without any microbial count. From the present findings it is concluded that karonda candy with 65 Brix sugar is suitable sugar concentration for karonda candy preparation.
The present investigation was carried out during Rabi season 2019-2020 at experimental field, Department of Horticulture, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.), India. The experiment was laid out in Randomized Block Design with three replications and 12 treatments of GOLDEN ROD (Salidago canadensis) L. C.v. GOLDEN GATE. T1- N:P:K-75:85:70kg/ha, T2- N:P:K- 75:100:75kg/ha, T3- N:P:K-75:110:85kg/ha, T4- N:P:K-75:120:90kg/ha, T5- N:P:K-75:130:95kg/ha, T6- N:P:K-75:135:100kg/ha, T7- N:P:K-75:140:110kg/ha, T8- N:P:K-85:145:115kg/ha, T9- N:P:K- 100:150:120kg/ha, T10- N:P:K-110:160:125kg/ha, T11- N:P:K-125:170:130kg/ha, T12- Control (water spray). Highest plant height (130.3 cm) and plant spread (E-W) (70.7 cm) was obtained from T4- N: P: K-75:120:90kg/ha where as highest plant spread (N-S)(67.27cm) was obtained from T1- N:P:K-75:85:70kg/ha. Highest No. of stocks/plant (15.67), length of the stock (44.13 cm), weight of the stock (56.1cm), no. of days for 50% flowering (82.33) no. of days for 100% flowering (113.0) vase life when kept in water (10 days), vase life of stock when kept in 2% sugar solution (11.67 days) was obtained from T4 - N:P:K-75:120:90 kg/ha as it can be recommended treatment for farmers.
