Effect of Foliar Spraying of Different Calcium Concentrations on Performance tomato plant.

Abstract

The paper deals with Effect of foliar spraying of different Calcium concentrations on tomato plant performance, the calcium plays a key role in a diverse range of plant functions.

A study was conducted   In the spring 2023   in the Al-Ajailat region, Libya ,  was Seedlings planted  1200 at   standard distance between the standard distance between the lines is 80 cm, while the distance between seedlings in one line is 30-35 cm.

They were watered with water and addition mineral fertilizers to supplement the nutrient content to the optimal level and their growth clearly.

In experiment used three concentrations for Calcium T0 (control), T1 (200gm )  , T2(300 gm)  , T3 (500 gm) as to find out impact  of  Calcium  on  tomato growth.

The results showed that treatments T1 and T2 led to an increase in plant height, the number of branches, and an increase in the number of fruits, as they produced the largest amount of fruit (87.31 kg) and (82.45 kg), respectively.

The results are also proven when increased the concentration of the ca element to 500 in treatment t3, it has a negative effect on the plant, leading to decrease in fruit to  (45.48 kg). 

The results of the test also, showed that no spraying with ca at treatment T0 leading to decrease fruit yield   and Blossom-end rot incidence increased (BER), which produced 9.57 kg un deformed fruits and 7 kg of distorted fruits.
