Answer 1

Your insert query, before you edited your question, contained ...

...VALUES ('$plantation_journal_no',$configurarion','$slope','$water_table_in_...

Notice that your single quotes aren't matched. You should have

...VALUES ('$plantation_journal_no','$configurarion','$slope','$water_table_in_...

If you had checked for an error in your query you would have found this problem immediately. Code like this would have helped.

if($result){
    echo "<script>alert('data submitted.');</script>";
    header("Location:create_journal.php");
}
else {
    die  $mysqli->error;
}

Pro tip : Format your code so you don't have to scroll horizontally to see entire queries. It's far easier to examine your queries and find mistakes that way. You can use php's heredoc syntax for string constants to do that.

This is how it looks.

    $sql= <<<INSERTQUERY
INSERT INTO `plantation_journal_nursery_details`
       (`plantation_journal_no`, `location`, `area`, `type_of_nursery`, 
        `central_nursery_name`, `state_nursery_name`, `mother_bed_size`, 
        `quantity`, `source_of_seed`, `polypot_bed_size`, `quantity_p`, 
        `hycopot_bed_size`, `quantity_h`) 
  VALUES 
       ('$plantation_journal_no','$location','$area1','$type_of_nursery',
        '$central_nursery_name','$central_nursery_name','$mother_bed_size',
        '$quantity_m','$source_of_seed','$polypot_bed_size','$quantity_p',
        '$hycopot_bed_size','$quantity_h');
INSERTQUERY;
