Influence of true potato seed genotype and foliar nutrient fertilizer on yield components

الملخص EN

The experiment was conducted at Greenhouse / Faculty of Agriculture, Al-Qasim Green University, to study the seedling response of three true potato seed (TPS) genotypes (MSL211, MSV093-1 and MSS927-01) to foliar fertilizer (0, 5, 10 g.L-1).

The seeds were soaked for 24 hours and planted in planting dishes, the seedlings were cared until 40 days age.

The seedlings were transferred to plastic house for a field experiment according to randomized complete block design with three replications.

The spraying were done 15 days intervals with neutral fertilizer (20-20-20 N-P-K).

After crop maturity, the data were taken as average of 10 plants by calculating plant tubers number , tuber average weight and plant tubers yield.

The genotype MSS927-01 was significantly superior in plant tuber number, average tuber weight and yield per plant ( 5.5, 7.3 g and 40.82 g , respectively).

The fertilizer was significantly affected yield components compared to control and high concentration was significantly superior by increasing plant tuber number, average tuber weight and plant tuber yield to 5.7 , 7.8 g and 44.54 g ,
