A review of constraints to ware Irish potatoes production in Kenya
Irish potatoes are an important food crop in Kenya, with production volumes only second to maize. Potatoes are produced in the cool highlands mostly by small scale farmers under rain-fed conditions. The soils in these areas are generally acidic and of low fertility due to anthropogenic activities. The national production is far below the potential, largely due to limited use of certified seeds, low...

Nutrient content of important fruit trees from arid zone of Rajasthan
Forests have provided food and shelter to man since ages. About 20% of the plants occurring in the forests are reported to have direct utility to mankind. Around 600 plant species in Indian forests are ennumerated to have food value. Arid zone vegetation comprises a wide range of edible fruit bearing and food producing species viz. Capparis decidua (ker), Cordia...

Investigation of variations of the morphological values and flowering shoot yield in different mint species at Iran
This experiment was carried out using a randomized complete block design with three replications. The factor studied included mint species (Mentha longifolia var. amphilema (from Qazvin and Ardabil localities), Mentha spicata (from Tehran and Yazd localities), Mentha piperita (from Tehran and Ardabil localities) and Mentha aquatica (from guilan and Ardabil localities)...

Oxidative stress and antioxidant activity as the basis of senescence in Hemerocallis (day lily) flowers
Senescence can be viewed as a developmental change that leads to the death of plant tissues. Naturally senescence is generally accepted as being genetically programmed. Petals are the floral organs which primarily determine the commercial longevity of flowers and as a consequence, it is necessary to study the physiological, biochemical and genetic processes that occur during floret senescence. Most of the...

Genetic diversity analysis of Iranian citrus varieties using micro satellite (SSR) based markers
Fifteen SSR Primer Pairs were used to estimate the level of polymorphism among 23 Citrus genotypes and four natural hybrids or bud mutation was selected from Kotra Germplasm Bank (IRAN). All fifteen loci assayed in citrus plant possessed a high level of polymorphism, with the number of alleles per locus ranging from 4 in TAA41 to 12 at CAT01, ATC09, AG14 ( an average, 8.27 alleles were detected per...

Use of male gametocide: An alternative to cumbersome emasculation in coriander (Coriandrum sativum L.)
New varieties of the coriander are traditionally bred using either mass selection or pure line selection or recurrent selection. Attempts to use hybridization to combine desirable traits were scarcely successful due to cumbersome emasculation. Hence, using male gametocides as an alternative to hand emasculation offers immense scope. The present study is taken up to assess five gametocides viz. Gibberellic...

A review of edible orchids in Malawi
Orchids are mostly known for their beautiful flowers, and food-flavoring products which make them a resource of great economic importance in the global horticultural and food industries. But in the Southern African region, orchids are particularly important for their tubers which are used for food, and are therefore traded within and across the countries. A number of researchers have reported a dramatic rise...

Effect of nitrogen and phosphorous rates on fertilizer use efficiency in lettuce and spinach
In this study, Lettuce (Lactuca Sativa) and Spinach (Spinacea Oleracea) were used as a case study vegetable crop to compare models for estimating Fertilizer Use Efficiency based on nitrogen and phosphorous fertilizer and nitrate concentration. Field studies were conducted to measure yield, nitrate, Fertilizer Use Efficiency, response to applied Nitrogen and phosphorous fertilizer in two plants. The...
