Effect of iron spray on growth and nutrient contents of karonda (Carissa carandas L.)

Abstract

Plant nutrition is necessary for the productivity and quality improvement of different fruit crops. The fruit crops being perennial in nature are quite different from other seasonal crops in their nutritional requirements due to their density, rate of root growth and the fruit bud differentiation in previous season and it relationship with yield in the following year. Determination of nutritional needs of the karonda (Carissa carandas L.) has to be made prior to the renewed growth or determination of the potential yield. However, reliable information is needed to decide, how much manures and fertilizers should be given to fruit trees for an economic response (Bhargava and Singh, 3). Karonda is an important fruit crop yet its production has not been satisfactory due to some constraints in its cultivation. One of the most important factors which limit the production is nutrition. If it is not maintained at proper level, higher yield and better fruit quality can not be achieved.
