A review on Justicia adhatoda: A potential source of natural medicine
It has been established that up to 25% of the drugs prescribed in conventional medicines are allied directly or indirectly to natural substances mostly of plant origin. Hence, during the last few decades there has been an increasing interest in the study of medicinal plants and their long-established use in different countries. However, today it is compulsory to afford scientific testimony as to whether it is reasonable...

Salinity tolerance of rice lines related to endogenous abscisic acid (ABA) level synthesis under stress
As the plant hormone abscisic acid (ABA) is involved in responses to salinity stress. We tested its putative relationship with the degree of tolerance to this abiotic stress. For this purpose we have examined the responses of sensitive (IR29) and tolerant (IR651) varieties of indica rice (Oryza sativa L.) to a range of salinity (0 (control) and 100 mM NaCl). Shoot and root dry weight was reduced and leaf Na...

Effect of drought stress and N fertilizer on yield, yield components and grain storage proteins in chickpea (Cicer arietinum L.) cultivars
Among the unfavorable environmental conditions, water deficit is the most significant factor that adversely affects plant growth, development and productivity. To determine the effects of drought stress and N fertilizer on yield, yield components and grain protein profiling pattern of chickpea (Cicer arietinum L.) a field experiment was conducted on a clay soil, in Razi University of Kermanshah, Iran. The...

Effects of fungicides on pollen germination peach and nectarine in vitro
Alive pollen with good viability and germination ability for fruit setting in peach and nectarine is necessary. For pollen viability test and aware of pollen quality in these fruits, experiment was done in vitro conditions based on effects of eight fungicides including Sumi-eight, Cupravit, Karatane, Topsin-M, Vitavax thiram, Beam, Benlate and Tecto at commercially recommended concentrations and at double...

Economic aspects of intercropping systems of vegetables (okra, tomato and cowpea)
Various field experiments were conducted in the cropping seasons of 2007 and 2008 to evaluate the agro-economic returns obtainable from the intercrop involving tomato, okra and cowpea at varying levels of cropping densities. The experimental design used for each of the field analyses was randomized complete block design with each of the treatments replicated three times. Average of yields over the consecutive two-year...

Relationship between morphological characters, dry matter yield and fruit yield of cucumber
Field experiment was conducted during the wet season of 2008 at the Teaching and Research Farm of Ambrose Alli University, Ekpoma (Lat. 6° 45' North and Long. 6° 08' East and an altitude of 460 metres above sea level), to evaluate the relationship between farmyard manure, inorganic fertilizer and dry matter weights on the yield of cucumber. The experiment consisted of one variety of cucumber (Ashley),...

Response of germination, growth and yield of okra (Abelmoschus esculentus) to seed priming duration and p-sources in Northwest Pakistan
An experiment was conducted at Horticulture Research Farm, KPK Agricultural University Peshawar during summer 2008 to evaluate the response of okra to phosphorus sources and soaking durations. The experiment was laid down in randomized block design with three replications. Four priming sources that is, distilled water, Diammonium phosphate (DAP), single super phosphate (SSP), SSP + Na2CO3and 4 h durations up to 48 h...

Micrografting and micropropagation of olive (Olea europea L. ) Iranian cultivar: Zard
A protocol for micropropagation and micrografting of shoots of olive (cv. Zard) was developed in Iran, because this variety of olive (cv. Zard) had difficult in proliferation. Three-week-old seedlings were used as rootstock. Lateral meristems (1 to 1.5 cm long), taken from olive (cv. Zard) mother plants, were cut and grafted onto healthy olive seedlings, micrografts cultured on OM medium culture...

Evaluation of tomato (Lycopersicon esculentum L.) variety tolerance to foliar diseases at Kenya Agricultural Research Institute Centre-Kitale in North west Kenya
Most vegetable cultivar evaluation trials focus on yield and quality attributes. However, disease tolerance is not routinely evaluated along with other parameters. The objective of this study was to evaluate new tomato cultivar for yield, quality and tolerance to foliar diseases. The most ubiquitous and devastating pathogen that infects tomatoes in the North rift Kenya is Phytophthora infestans that causes...

Distribution, Biology and Ecology of Parthenium hysterophorus L. (Congress Grass) an invasive species in the North-Western Indian Himalaya (Himachal Pradesh)
Parthenium hysterophorus L. is a native plant of sub-tropical America and it is rapidly invading in the North-Western Indian Himalaya (Himachal Pradesh), from last two decades onwards. Here, it invaded up-to 2000 m altitude from mean sea level and drastically effecting native plant resources in the invaded habitats. The density and dominance of the P. hsterophorus has been higher in the summer and...
