The effect of pH on stem-end blackening of potato.

Experimental evidence that the stem-end blackening pigment of potatoes is a compound of iron.

Assessment of Foliar Application of Iron and Silicon on Some Agronomic, Quanti-tative and Qualitative Parameters of Potato (Solanum tuberosum L.)

This study aimed at evaluating some quantitative and qualitative properties of potato as one of the main commercial products in Iran. To this end, a split plot experiment on the basis of randomized complete bloke design with silicone and iron was carried out in jiroft as one of the commercial area of planting potatoes. The main factor included different levels of silicon (0, 10, 20, 30 mM.l-1) ...

Effect of under Irrigation Management on Potato Performance Components

To evaluate the effect of water, tape drip and furrow irrigation methods on the performance components and features of Agria cultivar potato, an experiment was carried out in the agriculture faculty of Kermanshah. Repeated three times, this study was carried out in the form of full random blocks with the main factor of different amounts of irrigation water in three levels (50, 75, and100 percen...

Evaluation of β-amylase Activity of Sweet Potato (Ipomoea batatas) Cultivated in Iran

Besides the high starch content, sweet potato contains endogenous amylases where the two Predominants are - and β-amylases. Sweet potato is thought to be a promising source of β -amylase since β -amylase is one of the major protein in the tubers. This investigation has focused on the properties of β amylase from white-flesh sweet potato that has been grown in Iran as a potential source for indu...

Effect of cover crops and application of nitrogen fertilizer on tuber yield and nitrogen use efficiency of potato (Solanum tuberosum L. cv. Sante)

Inclusion of cover crops in crop rotations has several benefits such as supplying nitrogen for the next crop. To investigate the effect of cover crops and different levels of nitrogen fertilizer on tuber yield, yield components, and different nitrogen efficiency indices of potato, a filed experiment was conducted as split plots arrangements in randomized complete block design with three replica...
