A critical review on effect of fertilizers and plant densities on growth, yield and yield attributes of cucurbitaceous crops
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2017, Vol 6, Issue 7
Abstract
Cucurbits comprise 117 genera and 825 species. Out of this 30 species of nine genera are used as cultivated plants. Most of the cucurbits viz., cucumber, bottle gourd, ridge gourd, bitter gourd, snake gourd, water melon and muskmelons are monoecious and annul in habit. However plants like pointed gourd, spine gourd, ivy gourd and chow-chow are dioecious and perennials. It is of high market demand with a special delicacy for the people of India and it fetches premium price in the market. Though are potential vegetable crops, there is not much standardized scientific cultivation technology available for improving the yield. Agro techniques like nutrition and spacing play an important role in commercial production. Spacing is an important factor which will influence the plant population and affect the nutrient uptake in plants by creating competition between plants for nutrients, water and availability of light to the plants for synthesizing the food. By manipulation of inter and intra row spacing, several workers reported higher yields. Under field conditions, optimum nitrogen, phosphorus and potassium should be supplied to overcome the bottleneck of production. Several workers reported higher yields with nutrients. However, information on spacing, nitrogen, phosphorus and potassium requirements of pointed gourd, spine gourd, chow-chow and ivy gourd is scarce under Indian conditions. The relevant literature pertaining to the fertilizer and plant densities on growth, yield and yield attributes is reviewed and presented here under with the following sub-heads. Fertilizer studies on growth, yield and yield attributes of cucurbits. Plant density studies on growth, yield and quality yield attributes of cucurbits. Interaction studies between different fertilizer and plant densities on growth, yield and yield attributes of cucurbits.
